NetWare Btrieve v6.1 in the NetWare Environment
===============================================
The NetWare 3 (v3.11 and v3.12) and NetWare 4 (v4.0 and v4.01) operating
systems provide a nonpreemptive, multitasking environment. NetWare
Loadable Modules (NLMs) reside in server memory with the NetWare
operating system.
IMPORTANT: In a NetWare 4 environment, NetWare Btrieve v6.1 runs at
the highest privilege level (domain 0), with direct access
to the NetWare operating system. You cannot run NetWare
Btrieve v6.1 in protected mode (domain 1, 2, or 3).
You can run NetWare Btrieve v6.1 in a NetWare 3 (v3.11 and v3.12) or a
NetWare 4 (v4.0 and v4.01) environment. The list of NetWare products
with which you can run NetWare Btrieve v6.1 will be updated as the
products become available and are tested.
Before You Begin
================
Before you proceed with the installation procedure in the next section,
perform these preliminary steps:
1. If you have an earlier version of NetWare Btrieve loaded on your
system, unload it before you install NetWare Btrieve v6.10c.
2. If you have an earlier version of CLIB.NLM loaded on your system,
unload it before you load the new version of CLIB.NLM.
3. If you have a later (more recent) version of CLIB.NLM on your
system, use that version rather than installing the version that
comes with this release of Btrieve.
Installation Procedure
======================
To upgrade your existing NetWare Btrieve program files in a NetWare 3
(v3.11 or v3.12) or NetWare 4 (v4.0 or v4.01) environment, follow the
installation procedure outlined in the following table. An "X" in either
of the first two columns indicates that the step applies to that NetWare
environment.
NOTE: The following installation procedure replaces the NetWare
INSTALL procedure documented in Chapter 3 in the "Btrieve
Installation and Operation" manual. Upon completion of this
installation procedure, refer to "Configuring Btrieve" in
Chapter 3 in the "Btrieve Installation and Operation" manual.
NetWare NetWare
v3.11 3.12/4.x Installation Procedure
------ -------- -----------------------
From the NetWare Btrieve v6.10c Upgrade source
media:
X 1. Copy the AFTER311.NLM, CLIB.NLM, and
NWSNUT.NLM files in the \NW311 directory to the
\SYSTEM directory on the NetWare server.
NOTE: NetWare v3.12 and NetWare v4.x include
these files, so you do *not* need to copy them
if you are using either of those versions of the
operating system. Note that if you *do* attempt
to use these NetWare v3.11-specific files in a
NetWare v3.12 or a NetWare v4.x environment,
your server may end abnormally.
X X 2. Copy all the .NLM files and corresponding
.HLP files in the \SYSTEM directory to the
\SYSTEM directory (or to the appropriate
subdirectory for your configuration) on the
NetWare server.
X X 3. Copy the BSTART.NCF and BSTOP.NCF files in
the \SYSTEM directory to the \SYSTEM directory
(or to the appropriate subdirectory for your
configuration) on the NetWare server.
X X 4. Copy all the program files in the \PUBLIC
directory to the \PUBLIC directory (or to the
appropriate subdirectory for your configuration)
on the NetWare server.
X NOTE: Copy the NWLOCALE.DLL file in the
\PUBLIC\OS2 or \PUBLIC\WIN directory to the
appropriate subdirectory on the NetWare server
or on the hard drive of the client workstation.
NetWare v3.12 and v4.x includes these files, so
you do not need to copy them.
X 5. Copy the .MSG files in the \SYSTEM and
\PUBLIC directories to the appropriate language
subdirectory in \SYSTEM\NLS on the NetWare
server.
X X 6. Use the Btrieve Setup utility to configure
NetWare Btrieve according to your application's
requirements. For more information about the
Setup utility, see Chapter 3, "Installing and
Configuring Btrieve" in the "Btrieve
Installation and Operation" manual.
NetWare Btrieve v6.1 Upgrade Information
========================================
For a description of the enhancements to NetWare Btrieve v6.1, refer to
Chapter 1 of the "Btrieve Installation and Operation" manual.
Before you start NetWare Btrieve v6.1, read the following sections in
this document.
- NetWare Btrieve v6.1 File Recovery -- Outlines how to ensure
uncorrupted Btrieve files when upgrading to NetWare Btrieve v6.10c.
- NetWare Btrieve v6.1 File Format -- Addresses some of the
differences between the NetWare Btrieve v6.1, v6.0, and v5.x file
formats.
- NetWare Btrieve v6.1 Record Locking -- Describes the new
implementation of record locking within concurrent transactions.
- NetWare Btrieve v6.1 Operations -- Highlights the new NetWare
Btrieve v6.1 chunk operations and the restrictions that apply when
using NetWare Btrieve v6.0 to operate on records larger than 64 KB.
- NetWare Btrieve v6.1 Utilities -- Provides important notes on
NetWare Btrieve's logging feature.
- NetWare Btrieve v6.1 Requesters -- Highlights the new NetWare
Btrieve v6.1 configuration options for the DOS and OS/2 Requesters.
- NetWare Btrieve v6.1 Communications Programs -- Describes the
enhanced NetWare Btrieve Message Router that provides NetWare
Btrieve support for NLMs that need to run in the IOEngine of a
NetWare SFT III server.
- NetWare Btrieve v6.1 Status Codes -- Discusses error conditions
specific to different versions of NetWare Btrieve.
NetWare Btrieve v6.1 File Recovery
----------------------------------
If you have a previous version of NetWare Btrieve and you are upgrading
to NetWare Btrieve v6.10c, ensure that you have uncorrupted Btrieve files
before continuing any further. To detect file corruption, perform either
of the following procedures for each Btrieve file immediately after
installing NetWare Btrieve v6.10c.
- Method 1 -- Implement this procedure if you have large files and
are interested in detecting PAT corruption only.
- Method 2 -- Implement this procedure if you are interested in
detecting PAT corruption as well as other types of file corruption.
NOTE: Before you perform either procedure, make a backup of your Btrieve
files.
Method 1 -- Detecting PAT Corruption
1. Determine the page size of each Btrieve file using the BUTIL
-STAT command.
2. Use the BUTIL -SALVAGE command on each Btrieve file.
Note: The SALVAGE command does not recover records from your Btrieve
file. Therefore, this repair procedure will not take as long to complete
as when using the BUTIL -RECOVER command.
a. If the utility does not report PAT corruption, the file is
fine. You do not have to take further corrective measures.
b. If the utility reports PAT corruption, proceed to step 3.
3. The utility asks if you wish to repair the file. Select Yes
and provide the page size that you recorded for the file in step 1.
4. Use the BUTIL -SALVAGE command a second time on each Btrieve
file.
a. If the utility fully recovers the PAT pages on the first
run, it reports no errors. The file is fine. You do not
need to take further corrective measures.
b. If the utility again reports PAT corruption, proceed to step
5.
5. Make sure you have enough disk space to hold two copies of the
Btrieve file you are working with.
6. Use the BUTIL -CLONE command to create a duplicate empty Btrieve
file.
7. Use the BUTIL -COPY command to recover records from the damaged
file and insert them into the new file.
8. You may now resume normal operation with your NetWare Btrieve
application.
Method 2 -- Detecting PAT Corruption and Other Types of Corruption
1. Use the BUTIL -SALVAGE command on each Btrieve file.
a. If the utility does not report PAT corruption, the file is
fine. You do not need to take further corrective measures.
b. If the utility reports PAT page corruption, proceed to step
2.
2. The utility asks if you wish to repair the file. Select No.
3. Make sure you have enough disk space to hold two copies of the
Btrieve file you are working with.
4. Create a description file for each Btrieve file that must be
recovered. (See Appendix A, "Description Files" in the "Btrieve
Installation and Operation" manual for instructions.)
5. Use the BUTIL -CREATE command to create a duplicate empty Btrieve
file. (Using the CREATE command ensures an uncorrupted Btrieve
header. You can also use the BUTIL -CLONE command to create the
duplicate empty Btrieve file, but this command does not guarantee a
clean header.)
6. Use the BUTIL -COPY command to recover records from the damaged
file and insert them into the new file.
7. You may now resume normal operation with your NetWare Btrieve
application.
NetWare Btrieve v6.1 File Format
--------------------------------
When creating files, Btrieve v6.0 and v6.1 use a new file format that
allows faster data access than possible with versions of Btrieve prior to
v6.0. This new file format, first introduced in Btrieve v6.0, has been
slightly modified in Btrieve v6.1. For more information on the Btrieve
v6.1 file format, refer to the "Btrieve Programmer's Manual" included in
the NetWare Btrieve v6.1 Developer's Kit Supplement, which is available
through the Novell Professional Developers' Program (PDP).
When working with Btrieve files created with different versions of
Btrieve, consider the following.
- New file features supported by Btrieve v6.1 include the following:
multiple alternate collating sequences (ACSs), locale-specific ACSs,
Variable-tail Allocation Tables (VATs), and the ability to mark a
file as using index balancing.
Btrieve v6.1 returns a file version of 6.1 if the file specified in a
Stat operation or BUTIL -STAT command was created with multiple ACSs,
locale-specific ACSs, VATs, or the index balancing option.
NOTE: Files created with any of these features are created in the
Btrieve v6.1 file format. If Btrieve v6.1 creates a file without any of
these features, it creates the file in the Btrieve v6.0 file format by
default. You can override the v6.0 default and create Btrieve v5.x files
by using the Setup utility. Refer to Chapter 3, "Installing and
Configuring Btrieve" in the "Btrieve Installation and Operation" manual
for more information on the Setup utility.
- Btrieve v6.0 operates on a file created by Btrieve v6.1, unless
the file uses multiple ACSs, locale-specific ACSs, VATs, or the
balanced index flag. That is, Btrieve v6.0 cannot open a file that
uses the Btrieve v6.1 file format.
NOTE: Btrieve v6.0 returns a Status Code 30 (The file specified is not a
Btrieve file) when you attempt to open a file created in the Btrieve v6.1
file format. (This is generally true whenever you use an earlier Btrieve
version to open a file that has a more recent Btrieve file format.)
- Btrieve v6.1 can open files that were created with earlier
versions of Btrieve. For example, Btrieve v6.0 can open files
created with Btrieve v5.x, and Btrieve v6.1 can open files created
with Btrieve v5.x or v6.0. Additionally, Btrieve v6.1 can write to
files using the existing file format. In other words, Btrieve v6.1
writes to v5.x files using the v5.x file format and writes to v6.0
files using the v6.0 file format.
NOTE: When Btrieve v6.1 opens files from earlier versions, it does not
convert them automatically to the v6.1 file format. For example, if you
use Btrieve v6.1 to open a v6.0 file, Btrieve v6.1 does not convert the
v6.0 file to a v6.1 file format. However, if an application uses Btrieve
v6.10a on a v6.0 file and creates an index that uses a second ACS or a
locale-specific ACS, the file format will be upgraded to a version 6.1,
thus preventing the file from being opened by an earlier Btrieve version,
which would not recognize these features.
If your database contains files created with versions of NetWare Btrieve
prior to v6.1, you may want to upgrade them to take advantage of the
NetWare Btrieve v6.1 features. The Btrieve Rebuild utility converts
Btrieve data files to the v6.1 file format. Refer to Chapter 3,
"Installing and Configuring Btrieve" in the "Btrieve Installation and
Operation" manual for information on how to rebuild your existing Btrieve
files.
- NetWare Btrieve v5.x cannot open files that have a v6.0 or v6.1
file format.
NOTE: If you are using NetWare Btrieve v6.1 and you need backward
compatibility with Btrieve v5.x, use the Btrieve Setup option Create
Btrieve Files in Pre v6.x Format. This option allows you to create files
with NetWare Btrieve v6.1 and use them with Btrieve v5.x. (Keep in mind,
however, that many of the NetWare Btrieve v6.1 features require the
NetWare Btrieve v6.1 file format.) Refer to Chapter 3, "Installing and
Configuring Btrieve" in the "Btrieve Installation and Operation" manual
for more information on the Setup utility.
- NetWare Btrieve v6.1 supports a longer STS data type than NetWare
SQL.
NOTE: Make sure that the length of the STS data type does not exceed 15
bytes if you plan to use the NetWare Btrieve v6.1 files with NetWare SQL.
- NetWare Btrieve v6.1 allows the creation of an STS data type index
in files using the NetWare Btrieve v6.0 file format.
IMPORTANT: If you use NetWare Btrieve v6.00d or an earlier Btrieve
version to access a file with an STS data type index, a
server abend may occur.
NetWare Btrieve v6.1 Record Locking
-----------------------------------
NetWare Btrieve v6.1 provides more concurrency by allowing true
record-level locking in concurrent transactions. An explicit record lock
(by adding a bias to the Get and Step operations) does not lock the
corresponding data page; it locks only that particular record.
Additionally, NetWare Btrieve v6.10b/c provides the ability to share
locks between multiple cursors of the same file in an application.
Successful locking of a record (inside or outside a transaction)
guarantees that no other client is able to update or delete that record.
In other words, when a user performs an Update or Delete operation on a
record that he has previously locked, he will eventually succeed unless a
deadlock situation is detected. (A deadlock occurs when two or more
clients are each waiting on resources that one of the clients has not yet
released.)
If an application opens the same file multiple times, the locks issued by
different cursors do not block each other. The cursors are still
independent in the sense that they cannot explicitly unlock (using an
Unlock operation) the records that were locked by the other cursors.
After a cursor has read a record with a lock, a second cursor can update
or delete the record regardless whether this second cursor locked the
record. The first cursor will not get an error until it tries to delete
or update that record.
In general, when implementing multiple cursors within a concurrent
transaction, locks obtained on a cursor before the application starts a
concurrent transaction are automatically released when the cursor becomes
an active participant of that transaction. (A cursor becomes an active
participant of a concurrent transaction if a lock is requested or an
Insert/Delete/Update operation is executed with that cursor.) The
transaction does not have any effect on the inactive cursors. That is,
locks obtained before the transaction are still maintained after
ending/aborting the transaction of inactive cursors.
NetWare Btrieve v6.1 Operations
-------------------------------
NetWare Btrieve v6.1 supports the following new Btrieve operations. For
more information about these new operations, refer to the "Btrieve
Programmer's Manual" included in the NetWare Btrieve v6.1 Developer's Kit
Supplement, which is available through the Novell Professional
Developers' Program (PDP).
- Find Percentage and Get By Percentage -- Windows-oriented
applications can use these new operations for implementing scroll
bars.
- Get Direct/Chunk and Update Chunk -- NetWare Btrieve v6.1 allows
applications to operate on portions of a record, called "chunks,"
rather than on the entire record. Through the new Get Direct/Chunk
and Update Chunk operations, NetWare Btrieve v6.1 supports records
larger than 64 KB.
NOTE: Applications can use the new chunk operations to build records
larger than 64 KB in files that use the NetWare Btrieve v6.0 file format.
When NetWare Btrieve v6.0 operates on files containing records larger
than 64 KB, however, the following restrictions apply.
- If you use an Update Chunk operation in a file that uses the
NetWare Btrieve v6.0 file format, one of the file's Free Space
Lists may be left in a state that can cause NetWare Btrieve
v6.00d or an earlier NetWare Btrieve version to overwrite its
own cache; a server abend may occur.
- NetWare Btrieve v6.0 does not recognize the Get Direct/Chunk
or Update Chunk operations, and therefore can perform only
operations that update or retrieve entire records. Those
"entire record" operations can retrieve or update only up to 64
KB of a record because the operations' data buffer length
parameter, which specifies the amount of data to update or
retrieve, can contain a maximum value of 64 KB.
- If you use an Update Chunk operation to create a record
larger than 64 KB in a file that uses the NetWare Btrieve v6.0
file format, NetWare Btrieve v6.0 (which can use operations
only to update or retrieve entire records) cannot retrieve more
than the first 64 KB of the record.
NetWare Btrieve v6.0 returns a Status Code 22 (The data buffer
parameter is too short) or a Status Code 97 (The communications
buffer is too small) to indicate that there is more data to be
retrieved.
- Because NetWare Btrieve v6.0 does not recognize the Update
Chunk operation, you cannot use NetWare Btrieve v6.0 to modify
a record that is larger than 64 KB and still have the resulting
record be larger than 64 KB. You can use the Update operation
to shorten such a record. The length of the record resulting
from a successful Update operation is defined by the
operation's data buffer length parameter, which has a maximum
value of 64 KB.
NetWare Btrieve v6.1 Utilities
------------------------------
Btrieve Monitor Utility (BTRMON.NLM) -- The NetWare Btrieve v6.1 Monitor
utility (BTRMON.NLM) replaces the NetWare
Btrieve v5.x Console utility (BCONSOLE.NLM).
IMPORTANT: NLM applications that call NetWare Btrieve must
issue a Btrieve Reset before unloading. Failure
to do so may lead to a server abend when you try
to use the Btrieve Monitor utility to monitor
the NLM application's activity.
Rebuild Utility (BREBUILD.NLM) -- This new Btrieve utility
allows you to upgrade files created with
versions of NetWare Btrieve prior to v6.0. Use
this utility to upgrade your files to take
advantage of the NetWare Btrieve v6.1
features. For more information about rebuilding
your existing files, refer to "Rebuilding
Existing Btrieve Files" in Chapter 3 of the
"Btrieve Installation and Operation" manual.
NOTE: Before running the Rebuild utility (either from the
command line or through the Setup utility), you must start
NetWare Btrieve v6.1.
Roll Forward Utilities (BROLLFWD.EXE, PBROLL.EXE, and WBROLL.EXE) -- When
using NetWare Btrieve's logging feature and the Roll Forward utility,
consider the following:
- NetWare Btrieve does not allow a log file to contain log entries
created by different versions of NetWare Btrieve. That is, all
entries in a log file must be logged under the same version of
NetWare Btrieve. Otherwise, NetWare Btrieve displays a system error
message on the server console and ignores logging for the Btrieve
file.
- If you need to restart NetWare Btrieve, specify the same index
balancing setting that was used when you first loaded NetWare
Btrieve (after a backup) and performed logging. Otherwise, you may
receive a Status Code 43 (The specified record is invalid) when you
run the Roll Forward utility.
- If you need to run the Roll Forward utility (for example, after a
system crash), load the same version of Btrieve and specify the same
index balancing setting that was used during logging. Otherwise,
you may receive a Status Code 43 (The specified record is invalid).
NOTE: If you want to switch to a different version of NetWare
Btrieve, or you want to change the index balancing
setting, first create a backup of the Btrieve files to be
logged and then delete the corresponding log files.
- If you attempt to create a log file for a Btrieve file that
contains records larger than 57 KB, you may receive a Status Code 43
(The specified record is invalid) when you run the Roll Forward
utility.
The NetWare Btrieve v6.1 BROLLFWD.EXE file for DOS workstations
replaces the NetWare Btrieve v6.0 file DBROLL.EXE.
NetWare Btrieve v6.1 Requesters
-------------------------------
NetWare Btrieve Requester for UnixWare -- This new Requester
provides UnixWare clients with access to Btrieve data residing on a
NetWare Btrieve server. For detailed information about this
Requester, refer to the separate Readme document, BTRUNIX.TXT, that
is included in this upgrade.
NetWare Btrieve Requester for DOS -- This Requester has three new
configuration options. For detailed information about this
Requester, refer to Chapter 4 in the "Btrieve Installation and
Operation" manual.
- NetWare Runtime Server Support (/C) -- Enables or disables NetWare
Runtime support.
- DOS Session Load (/L) -- Allows you to load another instance of
the Btrieve DOS Requester even if it is already loaded. This option
is useful if you want to run Windows applications using the Btrieve
DOS Requester while running DOS VM applications that are also using
the Requester.
- Real-Time Data Compression (/O) -- Helps reduce network traffic by
reducing the number of packets required to complete a request to
Btrieve.
NetWare Btrieve Requester for OS/2 -- This Requester also provides
Runtime Server support. For detailed information about the NetWare
Btrieve OS/2 Requester, refer to Chapter 4 in the "Btrieve
Installation and Operation" manual.
NetWare Btrieve v6.1 Communications Programs
--------------------------------------------
An enhanced NetWare Btrieve Message Router (BROUTER.NLM) and a new
communications module (BTRVSTUB.NLM) were provided with NetWare Btrieve
v6.10b to support NLMs that need to run in the IOEngine of a NetWare SFT
III server. BROUTER.NLM redirects all Btrieve calls from the IOEngine to
NetWare Btrieve running in the MSEngine (Mirror Server Engine).
To run NLMs that require Btrieve in the IOEngine, perform the following
steps:
1. Load BTRIEVE.NLM and BSPXCOM.NLM in the MSEngine. You can
configure the BSTART.NCF NetWare command file to load these NLMs.
NOTE: Depending on the particular NLM that you will be running in
the IOEngine, you may need to increase BSPXCOM's data buffer size
with the Btrieve Setup utility (BSETUP.NLM). Consult the "Btrieve
Installation and Operation" manual for more information.
2. Load AFTER311.NLM in the IOEngine.
3. Load BTRVSTUB.NLM in the IOEngine. This NLM provides Btrieve API
names so that BROUTER.NLM may be loaded.
4. Load BROUTER.NLM in the IOEngine.
NOTE: Depending on the particular NLM that you will be running in
the IOEngine, you may need to increase BROUTER's data buffer size
with the Btrieve Setup utility (BSETUP.NLM). Consult the "Btrieve
Installation and Operation" manual for more information.
NetWare Btrieve v6.1 Status Codes
---------------------------------
Status Code 11 (The specified filename is invalid) -- If you receive
this status code when you open a Btrieve file using the NetWare Btrieve
OS/2 Requester (BTRCALLS.DLL), make sure that you are using the latest
NetWare OS/2 Requester.
Status Code 30 (The file specified is not a Btrieve file) -- NetWare
Btrieve v6.0 returns this status code when you attempt to open a file
that has the NetWare Btrieve v6.1 file format. (This is generally true
whenever you use an earlier NetWare Btrieve version to open a file that
has a more recent file format.)
Status Code 43 (The specified record address is invalid) -- The Btrieve
Roll Forward utility receives this status code when the address acquired
from the Free Space List of the Btrieve file during an Insert operation
at roll forward time is different from the one received at logging time.
The synchronization problem with Free Space Lists occurs when you use
different versions of Btrieve or the same Btrieve version but with a
different index balancing setting.
The following is a summary of the specific conditions for which Status
Code 43 can be returned:
- During logging, you loaded Btrieve multiple times and did not
specify the same index balancing setting each time.
- You inserted or updated a record larger than 57 KB.
- At roll forward time, you loaded a different version of NetWare
Btrieve or the same NetWare Btrieve version but with a different
index balancing setting from what you used at logging time. To
correct the synchronization problem with Free Space Lists, load the
proper version of NetWare Btrieve with the proper index balancing
setting.
Status Code 44 (The specified key path is invalid) -- NetWare Btrieve
v6.1 returns this code for some situations in which earlier versions of
NetWare Btrieve returned Status Code 82 (The application lost
positioning). These situations can occur when you define the key
attribute to be manual or null (all-segment and any-segment). If you have
an existing NetWare Btrieve application that checked for Status Code 82,
you may want to rewrite the application to check for Status Code 44 as
well.
Refer to Chapter 2 in the "Btrieve Programmer's Manual" (included in the
NetWare Btrieve v6.1 Developer's Kit Supplement) for more information
about all-segment and any-segment null keys.
Status Code 102 (Insufficient stack space is available) -- NetWare
Btrieve v6.1 requires 3 KB of stack space. If your NLM application
receives this status code, try increasing the size of the stack in your
application. You may need more than 3 KB of stack space if you are
accessing files defined by NetWare SQL as being under referential
integrity (RI) constraints. Because NetWare Btrieve uses recursion when
enforcing these constraints, at least 3KB of stack space should be
available when you make the Btrieve call.
NetWare Btrieve v6.1 Program Files
==================================
The first part of this section includes information about the files that
comprise NetWare Btrieve v6.1. The second part lists the specific files
included in this NetWare Btrieve v6.10c Upgrade.

Code Changes in NetWare Btrieve v6.10c
======================================
The following information describes changes made to the NetWare Btrieve
v6.1 code. This current code was released in November 1993 as NetWare
Btrieve v6.10c. The descriptions for the NetWare Btrieve v6.10c engine
appear first, followed by those for the requesters, the utilities, and
the communications programs.
Each description includes one or more search strings. These search
strings indicate areas in which you may encounter the problem that this
specific code upgrade addresses. The search strings may help you quickly
determine whether the code you need for a specific problem is included in
this upgrade package.
NOTE: In some cases, the text describes a problem or reported bug that
the update does NOT fix. In those cases, use the workaround provided.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: BINARY KEY FLAG, CREATE COMMAND, EXTENDED KEY FLAG
Problem Fixed by This Upgrade:
If you set a key specification's key flag to both binary (4) and extended
(256) when creating a file, Btrieve creates the key as a binary rather
than an extended type. This code upgrade ensures that NetWare Btrieve
ignores the binary key flag and successfully creates an extended key.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: 25, 59, CREATE KEY NUMBER -1, OPEN FILE
Problem Fixed by This Upgrade:
When you attempt to perform a Create operation using -1 as the key number
parameter on a file that is already open, NetWare Btrieve returns Status
Code 25 (Btrieve cannot create the specified file). This code upgrade
ensures that NetWare Btrieve returns the correct status code, Status Code
59 (The specified file already exists).
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: 66, 67, 72, 73, ABEND, DEADLOCK, DELETE, INSERT,
REFERENTIAL INTEGRITY, UPDATE
Problem Fixed by This Upgrade:
When Referential Integrity (RI) is enabled on a database and two or more
clients attempt to perform Insert, Delete, or Update file operations
simultaneously, NetWare Btrieve may create a deadlock situation. In
addition, when two or more clients attempt to modify RI-referenced files,
the server may end abnormally, or NetWare Btrieve may incorrectly return
one of the following Status Codes: 66 (The maximum number of open
databases has been exceeded), 67 (Btrieve cannot open the SQL data
dictionaries), 72 (Btrieve cannot open the RI referenced file), or 73
(The RI definition is out of sync).
This code upgrade ensures that NetWare Btrieve handles such situations
correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: DATA COMPRESSION, FREE SPACE BIT
Problem Fixed by This Upgrade:
When you create a file with both fixed-length records and data
compression, NetWare Btrieve ignores the free-space specification. This
code upgrade ensures that the free space specification is now supported
when you select data compression.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: ABEND, HANG, REFERENTIAL INTEGRITY UTILITY /R OPTION
Problem Fixed by This Upgrade;
When you attempt to run the Referential Integrity utility (RIUTIL) with
the /R option, the NetWare Btrieve engine may hang, or the server may end
abnormally. This code upgrade ensures that NetWare Btrieve handles
RIUTIL -R operations correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: 5.X FORMAT FILES, DUPLICATABLE/NON-DUPLICATABLE KEYS,
CORRUPTED FILES
Problem Fixed by This Upgrade:
If you attempt to perform an illegal operation such as inserting a
duplicate key into a file that does not allow duplicates, the Insert
operation should fail. In one specific situation, however, NetWare
Btrieve does insert the record, but NetWare Btrieve inserts it
incorrectly and does not update the file's indexes.
Note that this situation occurs only when all four of the following
conditions are in effect during the Insert operation:
(1) The file is in a pre-v6.x file format.
(2) The file allows only one record per data page.
(3) A succesful insert operation would cause NetWare Btrieve to
allocate a new page to the file.
(4) The failed insert operation is followed by a successful insert.
Although the Insert returns an error status code in this situation,
indicating that the operation failed, the record is placed (incorrectly)
in the file, and you can access that record with Step operations but not
with Get operations.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: 132, 2 GB FILE SIZE, 512 PAGE SIZE, CORRUPTED FILE
Problem Fixed by This Upgrade
NetWare Btrieve specifies that v6.0 and v6.1 files with a page size of
512 can be no larger than 2 gigabytes in size. However, NetWare Btrieve
does not enforce this limit. As a result, when a file grows beyond the
512 page-size limit, NetWare Btrieve corrupts the file or overwrites
memory. This code upgrade ensures that NetWare Btrieve now returns Status
Code 132 (The file is full).
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: 80, 2+GB FILE, DELETE, STEP, UPDATE
Problem Fixed by This Upgrade:
NetWare Btrieve does not perform some operations correctly on files
larger than 2 gigabytes in size. Most notably, attempts to update or
delete a record with a "physical" address larger than 2 gigabytes will
fail, with NetWare Btrieve incorrectly returning a Status Code 80 (Record
conflict.) Also, attempts to perform a Step Next operation to access a
record with a "physical" address greater than 2 gigabytes incorrectly
returns a record much closer to the beginning of the file. This code
upgrade ensures that NetWare Btrieve handles files larger than 2 gigbytes
correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: COMPRESSION BUFFER, DEFAULT
Enhancement:
This release of NetWare Btrieve changes the value of one of the default
Btrieve load parameters. The default now specifies a compression buffer
of 8 kilobytes rather than a compression buffer of zero.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: PERFORMANCE DEGRADATION, STAT CALLS
Problem Fixed by This Upgrade
When an application makes a status call, NetWare Btrieve allocates memory
dynamically. Numerous STAT calls cause the engine to run more slowly,
which is the result of the operating system occasionally allocating
memory inefficiently. This code upgrade ensures that numerous STAT calls
do not cause undue performance degradation.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: 48, 49, -D LOAD OPTION, LOCALE-SPECIFIC ACS FILES,
INVALID PRE V6.0 FILES, STS DATA TYPE
Problem Fixed by This Upgrade:
If you load NetWare Btrieve with the -d option (Create Btrieve Files in
Pre v6.x Format), the engine incorrectly allows applications to create
locale-specific alternate collating sequences (ACSs) and STS key types,
both of which are Btrieve v6.1 file-format features. This code upgrade
ensures that NetWare Btrieve successfully blocks the creation of files
with these features when you specify the -d option. Instead, the engine
correctly returns either Status Code 48 (The alternate collating sequence
definition is invalid) or Status Code 49 (The extended key type is
invalid), as appropriate.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: KEY/FILE CORRUPTION, INSERTING RECORDS, TRANSACTION
Problem Fixed by This Upgrade:
After inserting records into a file as part of a transaction, NetWare
Btrieve occasionally corrupts the data file. This code upgrade ensures
that NetWare Btrieve handles this type of operation without file
corruption.
* * * * * * * * *
Product/Platform: NetWare Btrieve - BTRIEVE.NLM, v6.10
Search Strings: FILES NOT CLOSED AFTER CONTINUOUS OPERATIONS
Problem Fixed by This Upgrade:
NetWare Btrieve occasionally fails to close files after they are removed
from Continuous Operations mode. Although NetWare Btrieve returns a zero
from the call to end Continuous Operations mode, indicating that the
operation was successful and the files released, the Btrieve Monitor
Utility shows the files as still in use by the client who initiated
Continuous Operations mode until that client issues a Reset call. This
code upgrade ensures that NetWare Btrieve successfully closes all files
after completing a Continuous Operations procedure.
* * * * * * * * *
Product/Platform: NetWare Btrieve Requester for DOS - BREQUEST.EXE,
v6.10
Search Strings: RAM USAGE
Problem Fixed by This Upgrade:
The NetWare Btrieve DOS Requester uses 6K more RAM than earlier versions,
causing NetWare Btrieve to return Status Code 1002 (Btrieve cannot
allocate the memory needed). This code upgrade ensures that NetWare
Btrieve allocates the correct amount of RAM.
* * * * * * * * *
Product/Platform: NetWare Btrieve Requester for DOS - BREQUEST.EXE,
v6.10
Search Strings: 12, NETWARE 4.X
Problem:
The NetWare Btrieve Requester for DOS (BREQUEST) returns Status Code 12
(Btrieve cannot find the specified file) when you login to a NetWare 4.x
server and then attempt to run the requester. The problem does not exist
if you login to a NetWare 3.x server and then map a drive to the NetWare
4.x server prior to running the requester.
* * * * * * * * *
Product/Platform: NetWare Database Communications Requester for OS/2 -
NDBCOMM.DLL, v6.10
Search Strings: 3, OPEN, RESET/STOP, START TRANSACTIONS STATEMENTS, SPX
CONNECTION
Problem Fixed by This Upgrade:
The Communications Requester keeps an SPX connection usage count that it
increments after executing each START TRANSACTION statement. If you issue
more than approximately 64,000 START TRANSACTION statements without
issuing a RESET or STOP operation, the Requester resets the usage count
to zero, resets the SPX connection, and closes the file. The next START
TRANSACTION statement therefore returns Btrieve Status Code 3 (File Not
Open). This code upgrade ensures that the Requester handles such cases
correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve Requester Utility for DOS -
BREQUTIL.EXE, v6.10
Search Strings: DATA BUFFER LENGTH, GARBAGE VERSION NUMBER
Problem Fixed by This Upgrade:
When you load the client version of Btrieve, the NetWare Btrieve
Requester utility for DOS first prints the correct version number and
then prints garbage characters. This code upgrade ensures that Btrieve
resets the data buffer length correctly after a version call, printing
only the version number.
* * * * * * * * *
Product/Platform: NetWare Btrieve Requester Utility for DOS -
BREQUTIL.EXE, v6.10
Search Strings: RESET COMMAND
Enhancement:
This release of the NetWare Btrieve Requester utility has a new command,
RESET. The syntax is as follows:
BREQUTIL -RESET [ConnectionID]
This command performs a Btrieve Reset operation to release the resources
used by Btrieve at a workstation. RESET aborts any pending transactions,
releases all locks, and closes all open files for the workstation.
* * * * * * * * *
Product/Platform: NetWare Btrieve Maintenance Utility - BUTIL.NLM,
v6.10
Search Strings: DUPLICATE KEYS, DUPLICATE POINTER FLAG, LINKED
DUPLICATABLE STORAGE METHOD, STAT COMMAND
Problem Fixed by This Upgrade:
Executing the NetWare Btrieve Maintenance utility STAT command (BUTIL
-STAT) does not print the number of available duplicate keys in a file
that uses the linked duplicate method of storing duplicates. After you
drop one of the duplicate keys from that file, NetWare Btrieve does not
set the duplicate pointer flag in the file header, so the Maintenance
utility reports an incorrect number of available duplicate keys in the
file. This code upgrade ensures that BUTIL -STAT always prints the actual
number of available duplicate keys.
* * * * * * * * *
Product/Platform: NetWare Btrieve Maintenance Utility - BUTIL.NLM,
v6.10
Search Strings: 22, DATA COMPRESSION, RECORD LENGTH GREATER THAN PAGE
SIZE
Problem Fixed by This Upgrade:
The NetWare Btrieve Maintance utility (BUTIL) returns Status Code 22 (The
data buffer parameter is too short) when you attempt to copy data from a
Btrieve file that specifies data compression and also has a fixed record
length larger than the page size of the file. In addition, BUTIL fails
to create such a file. This code upgrade ensures that BUTIL creates and
processes this type of file correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve Maintenance Utility - BUTIL.NLM,
v6.10
Search Strings: 22, ACS, 5.X FILES, CLONE COMMAND, SUPPLEMENTAL INDEX
Problem Fixed by This Upgrade:
The NetWare Btrieve Maintenance utility - CLONE command (BUTIL -CLONE)
returns Status Code 22 (The data buffer parameter is too short) when a
supplemental key in a Btrieve 5.x file has an alternate collating
sequence (ACS). This code upgrade provides a larger buffer for this type
of operation.
* * * * * * * * *
Product/Platform: NetWare Btrieve Maintenance Utility - BUTIL.NLM,
v6.10
Search Strings: FILE VERSION, REDIRECTION OUTPUT PROBLEM, STAT COMMAND
Problem Fixed by This Upgrade:
The NetWare Btrieve Maintenance utility STAT command (BUTIL -STAT) does
not correctly redirect output after noting the file version. This code
upgrade ensures that BUTIL -STAT handles this type of situation
correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve Maintenance Utility - BUTIL.NLM,
v6.10
Search Strings: BUFFER SIZE, 5.x FILES, HEX 1A CHARACTER, LOAD COMMAND
Problem Fixed by This Upgrade:
The NetWare Btrieve Maintenance utility -LOAD command (BUTIL -LOAD) stops
the loading operation if it encounters a record that uses 0x1A as the
first, or first and last characters in the file. This code upgrade
instructs the -LOAD command to ignore the hex 1A character in this
situation. In addition, this code change also increases the maximum
buffer size to 57K for clients in order to accommodate handling large
records for v5.x files.
* * * * * * * * *
Product/Platform: NetWare Btrieve Maintenance Utility - BUTIL.NLM,
v6.10
Search Strings: VATS OPERATIONS FAILURE
Problem Fixed by This Upgrade:
The NetWare Btrieve Maintenance utility (BUTIL) is not handling
Variable-tail Allocation Tables (VATs) correctly, causing VAT operations
to fail. This code upgrade ensures that BUTIL handles VATs correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve Maintenance Utility - BUTIL.NLM, v6.1
Search Strings: COPY COMMAND COPYING INCORRECT NUMBER OF RECORDS
Problem Fixed by This Upgrade:
The -COPY command does not always copy the specified number of records.
This code upgrade ensures that BUTIL handles copying operations
correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve Maintenance Utility - BUTIL.NLM, v6.1
Search Strings: EMPTY FILE, LOAD COMMAND, VATS
Enhancement:
This code upgrade enables the NetWare Btrieve Maintenance utility (BUTIL)
to load Variable-tail Allocation Tables (VATs) into an empty file.
* * * * * * * * *
Product/Platform: Rebuild Utility - BREBUILD.NLM, v1.10
Search Strings: TTS BIT, CREATING TRANSACTIONAL FILES
Problem Fixed by This Upgrade:
The Rebuild utility does not work properly when you load NetWare Btrieve
using the -i option (Create files as transactional), which instructs
NetWare Btrieve to create a file with the TTS bit set. This code upgrade
ensures that the TTS bit is removed from a rebuilt transactional file
prior to renaming it to its original filename. After renaming the
rebuilt file, the TTS bit is again set for that file.
* * * * * * * * *
Product/Platform: Rebuild Utility - BREBUILD.NLM, v1.10
Search Strings: 28, TEMPORARY FILE
Problem Fixed by This Upgrade:
When the NetWare Create operation fails to create the Rebuild utility's
temporary file, the Create operation first returns Status Code 28 (The
record length is invalid). Then, although no temporary file was
generated during the Create operation, the Rebuild utility still attempts
to delete the non-existing file and then returns the message "BRebuild
could not delete temporary file xxxx.tmp." This code upgrade ensures
that the Rebuild utility handles temporary files correctly.
* * * * * * * * *
Product/Platform: Rebuild Utility - BREBUILD.NLM, v1.10
Search Strings: SPECIFYING MULTIPLE OPTIONS ON COMAND LINE
Problem Fixed by This Upgrade:
When you specify multiple options following the filename on the Rebuild
utility's command line, BREBUILD ignores those options. (If you specify
only one option following the filename, BREBUILD displays the syntax Help
screen indicating that you should specify options preceding the
filename.) This code upgrade ensures that the Rebuild utility correctly
parses all command-line options.
* * * * * * * * *
Product/Platform: Roll Forward Utility for DOS - BROLLFWD.EXE, v 6.10
Roll Forward Utility for MS Windows - WBROLL.EXE, v6.10 Roll Forward
Utility for OS/2 - PBROLL.EXE, v6.10
Search Strings: 4, DOUBLE SLASHES IN LOG FILE NAME, INCORRECT LOG FILE
SPECIFICATION
Problem Fixed by This Upgrade:
The NetWare Btrieve Roll Forward utilities do not always work correctly
when you enter a pathname to the log file that includes double slashes
preceding the server name, as in the following example:
\\server\vol:\path\btr.log
For example, if the log file is on a different volume, the Roll Forward
utilities return Status Code BROLLFWD-6.1-21 (The utility is unable to
open \\server\vol:\path\logfile. The number of the applicable system
error code is 2).
This code upgrade ensures that if you specify a pathname such as
\\server\vol:\path\logfile, the Roll Forward utilities change that path
to the following:
\\server\vol\path\btr.log
This is the pathname that appears on a print out of a log file.
In addition, this code upgrade also ensures that the Roll Forward
utilities accept any of the following as valid pathnames to a log file:
\path\btr.fil
\path\btr.fil=\path\btr.log
\path\btr.fil=\\server\vol:\path\btr.log (where the volume is either
the same or different than the default)
\path\btr.fil=\\server\vol:path\btr.log
* * * * * * * * *
Product/Platform: Roll Forward Utility for DOS - BROLLFWD.EXE, v 6.10
Search Strings: UNFORMATTED SCREEN DISPLAY
Problem Fixed by This Upgrade:
A number of Roll Forward messages are formatted incorrectly for screen
output. This code upgrade ensures that BROLLFWD correctly formats
messages displayed on the workstation screen.
* * * * * * * * *
Product/Platform: Roll Forward Utility for DOS - BROLLFWD.EXE, v 6.10
Search Strings: COMMAND-LINE FUNCTIONALITY
Enhancement:
This release of the NetWare Btrieve Roll Forward utility (BROLLFWD)
includes the ability to use the command line to instruct NetWare Btrieve
to roll your files forward. Note, however, that the functionality of the
utility has not changed.
* * * * * * * * *
Product/Platform: Roll Forward Utility for DOS - BROLLFWD.EXE, v 6.10
Search Strings: DBROLL
Problem Fixed by This Upgrade:
The Roll Forward utility DBROLL.EXE, which was used in the DOS
environment, is obsolete. It is no longer supported because it could not
be enabled for translation. Instead, use BROLLFWD to roll your files
forward in the DOS environment.
* * * * * * * * *
Product/Platform: Roll Forward Utilities for DOS and MS Windows -
BROLLFWD.EXE, v6.10 and WBROLL.EXE, v6.10
Search Strings: DISPLAYING KANJI DATA, /L OPTION
Problem Fixed by This Upgrade:
The Roll Forward utilities for DOS and MS Windows do not display Kanji
characters correctly when you attempt a roll forward operation using the
List File (/l) option. This code ensures that the utilities print the
correct Kanji data without displaying garbage characters. In addition,
this code also includes double-byte checking on print operations.

Product/Platform: Roll Forward Utility for MS Windows - WBROLL.EXE,
v6.10
Search Strings: ADD, OPENING FILE, OWNER NAME, QUEUE
Problem Fixed by This Upgrade:
The MS Windows Roll Forward utility does not apply the owner name on
write operations to files that require such a name. This occurs when the
owner name level is 1 or 3. This code upgrade ensures that WBROLL checks
for a correct owner name when the file is added to the queue. If,
however, you enter an incorrect owner name, WBROLL prompts you to reenter
that name if the owner level is 0 or 2, but it returns Status Code
WBROLL-6.1-2 (Continue roll forward?) if the owner level is 1 or 3.

Product/Platform: Roll Forward Utility for MS Windows - WBROLL.EXE,
v6.10
Search Strings: DOUBLE BACKSLASH IN PATHNAME, ROLLFORWARD FAILURE
Problem Fixed by This Upgrade:
When you attempt to add a file located in a root directory to the queue,
the MS Windows Roll Forward utilty incorrectly lists the file in the
queue with a double backslash (\\) as the first characters in the
pathname. In addition, when you attempt to roll the file forward, WBROLL
returns the following messages:
WBROLL-6.10-8: The following file was not found in BLOG.CFG
\\<filename>.
WBROLL-6.10-2: Continue roll forward?
This code upgrade ensures that WBROLL does not append a double backslash
to the filename if the last character in the Btrieve directory name
already contains a single backslash.

Product/Platform: Roll Forward Utility for MS Windows - WBROLL.EXE,
v6.10
Search Strings: ABORT OPERATION DOES NOT CLOSE BTRIEVE FILE
Problem Fixed by This Upgrade:
When you abort a roll forward operation before it completes, the MS
Windows Roll Forward utility does not close the Btrieve file that is
currently being rolled forward. This code upgrade ensures that WBROLL
handles this operation correctly.
* * * * * * * * *
Product/Platform: Roll Forward Utility for MS Windows - WBROLL.EXE,
v6.10
Search Strings: DIRECTORY ENDING IN BACKSLASH (\) CHARACTER
Problem Fixed by This Upgrade:
The MS Windows Roll Forward utility omits a backslash character (\)
between the directory name and the filename when the directory name
itself ends with a backslash. (For example, WBROLL incorrectly shows the
path x95x5C\test.btr as x95x5Ctest.btr.) This code upgrade ensures
that WBROLL handles directory names correctly.
* * * * * * * * *
Product/Platform: Roll Forward Utility for MS Windows - WBROLL.EXE,
v6.10
Search Strings: ENABLED FOR TRANSLATION
Enhancement:
This version of the MS Windows Roll Forward utility is enabled for
translation.
* * * * * * * * *
Product/Platform: Roll Forward Utility Resource File for MS Windows -
WBROLLRS.DLL, v6.10
Search Strings: KANJI CHARACTERS, GARBAGE CHARACTERS, QUEUE-ADD
Problem Fixed by This Upgrade:
The MS Windows Roll Forward utilty displays garbage characters in some
entry and filename fields that should contain Kanji characters. This
code upgrade changes the display character font in the resource file from
ANSI_FIXED_FONT to OEM_FIXED_FONT, ensuring the correct display of the
characters in the various fields.
* * * * * * * * *
Product/Platform: Roll Forward Utility for OS/2 - PBROLL.EXE, v6.10
Search Strings: LIST OF FILES READ INCORRECTLY
Problem Fixed by This Upgrade:
The OS/2 Roll Forward utility does not correctly read the test file that
contains the list of files to roll forward. This code upgrade ensures
that PBROLL handles such files correctly.
* * * * * * * * *
Product/Platform: NetWare Btrieve SPX Communication Program -
BSPXCOM.NLM, v6.10
Search Strings: PACKET PROCESSING
Enhancement:
The NetWare Btrieve SPX Communication Program (BSPXCOM) is processing
packets twice. This code upgrade ensures that BSPXCOM uses less CPU time
by processing each packet only once.

NetWare Btrieve Documentation
=============================
The NetWare Btrieve v6.10c Upgrade includes the same "Btrieve
Installation and Operation" manual that accompanied the NetWare Btrieve
v6.10b upgrade package. Currently, you can print the v6.10b manual using
the set of ASCII text files included in that upgrade.
NOTE: You can place an order for a printed manual through Novell
Fulfillment. For ordering information, see the "Novell Fulfillment"
section below.
This v6.10c upgrade package does not include an updated manual set,
although it does note changes to the documentation.

The following documentation updates apply to the "Btrieve Installation
and Operation" manual included in the v6.10b upgrade package.
Chapter 3, "Installing and Configuring Btrieve" -- Replace the
installation procedure in the "Using the NetWare INSTALL
section with the infor Utility" section with the
information presented in the "Installation Procedure"
section of this Readme document.
Chapter 4, "Configuring and Using the Requesters" -- In the "Loading
the Windows Requester" section, change the name of the

2. Print the document files, using a print utility of your choice.
3. Photocopy the printed Btrieve manual as needed.
Associated Documents
--------------------
For information about the Btrieve v6.1 file format and Btrieve
operations, refer to the "Btrieve Programmer's Manual." This manual is a
component of the NetWare Btrieve v6.1 Developer's Kit Supplement, which
is available through the Professional Developer's Program (PDP).
NOTE: Some NetWare Btrieve developers find it necessary or useful to
provide data dictionaries with their Btrieve-based products.
(Dictionaries are Btrieve files that you create and maintain
with the XQL products.) In addition to XQL, NetWare SQL
products, Developer's kits, and Xtrieve, there are also a
number of third-party products that provide this functionality.
For detailed information about data dictionaries, see "Using NetWare
SQL to Access Relational Inormation from Btrieve Data," NetWare
Application Notes, September 1992.
