NOVELL TECHNICAL INFORMATION DOCUMENT
TITLE: DS Enhancement Pak (DS.NLM v4.89a)
README FOR: DSENH.EXE
NOVELL PRODUCTS and VERSIONS:
NetWare 4.1
ABSTRACT:
The DS Enhancement Pak contains DS.NLM version 4.89 for NetWare
4.10 file servers. This file replaces the previous Directory
Services and provides increased performance, additional
functionality, and addresses any known issues. All NetWare 4.10
servers should be updated to this new version to obtain the new
functionality.

SOLUTION:
The DS Enhancement Pak contains DS.NLM version 4.89 for NetWare
4.10 file servers. This file replaces the previous Directory
Services and provides increased performance, additional
functionality, and addresses any known issues. All NetWare 4.10
servers should be updated to this new version to obtain the new
functionality.
Performance:
This DS.NLM significantly increases the performance of NetWare
Directory Services. Some of the improvements will be noticeable
to the users, while others will improve the background processes
and are not immediately apparent.
Changes in the login and authentication process will reduce the
time it takes to accomplish tasks when large numbers of users
attempt concurrent access. Improvements in the resolve name
routines will also allow DS to more quickly locate objects and
complete the required actions.
Background processes involving revision attributes and
backlinks have been altered to improve synchronization and
replication, especially when operations were not "normal" because
of server or communications faults. The introduction of a "tuned
resolve
name" ability in background consistency checking of external
references insures greater reliability and improved performance.
Bindery Services:
Code changes in how the bindery handles names have been
improved, and in general performance will be improved and server
utilization will be reduced. A name can now exist in more than
three of the bindery contexts set on a server and show up during
a list operation. Previously, this was not the case.
Management:
The addition of the "Partition Status" attribute makes it easy
to determine the health of background synchronization. This
attribute keeps a record of the last successful time a complete
synchronization cycle was accomplished. If synchronization
errors were encountered, a record of those errors is recorded in
this attribute. Included in the error record is the object on
which the failure occurred, the server to which synchronization
was being attempted and whether it was a local or remote error.
This status is displayed by the new DSREPAIR.NLM, the enclosed
sample utilities, and will be used in future management tools.
This functionality reduces the time required to administer the
Directory Services.
Internal DS commands were added to assist in making future
utilities more useful. These will promote self-healing and
global repair strategies. Status flags may be used in future
In addition to enhancement of the Directory Services Novell
continues to enhance the diagnostic and repair utilities. At
your convenience you should copy the DSREPAIR.NLM to the
SYS:\SYSTEM directory of each file server. The DSREPAIR.NLM
version 4.26b contains new functionality and will more
completely identify and correct data inconsistencies. The older
DSREPAIR.NLM version 4.23 may still be used with the new version
of the DS, but will not provide these improvements.
Although the DSREPAIR version 4.26 will identify and correct
data inconsistencies for any version of the DS you cannot obtain
status information from servers which are not running the new DS
version 4.89.
Once the new DS NLM is loaded and synchronization has occurred
the status information about DS replication and synchronization
will be available. The option on the first menu
"Report Synchronization Status" will display and log the status
of ALL copies of ALL replicas of ALL partitions contained on this
server. It will contact each server which contains a replica
copy and verify the status. If this involves multiple partitions
and many copies the screen display will scroll rapidly and the
logfile will be required to check the results.
By careful selection of servers you should be able to obtain
data on the status of your entire tree without checking all
servers.
A sub-set of the above information may also be obtained. From
the "Advanced Options" sub-menu you may select "Replica and
Partition Operations" and then select a partition. Selecting the
new option "Report Synchronization Status" will contact all
servers with a replica of that partition and then display and log
the status.
You may also select the option "View Replica Ring", select a
server, and display the status of the replica on that server.

Installation Instructions:
HOW TO INSTALL THE DS.NLM
If you are upgrading from NetWare 4 versions prior to 4.10
Please read the attached UPGRADE.TXT file first.
DS.NLM is normally installed as part of a server upgrade or new
install. It also may be loaded and activated on existing NetWare
4.10 servers without the need to restart the server.
Note: If you have installed the NetWire patch DSPRCSFX.NLM
version dated 4-28-95 it MUST be replaced with the version dated
5-10-95 and the server rebooted before the new DS is installed.
A. EXISTING 4.10 SERVERS
MANUAL METHOD
To install the new DS.NLM on an existing NetWare 4.10 server
you should:
1. Log into the network as ADMIN or a user with rights to the
SYS:\SYSTEM directory of a current NetWare 4.10 file server.
Locate the file SYS:\SYSTEM\DS.NLM
2. Copy the new DS.NLM file to the SYS:\SYSTEM directory of
the NetWare 4.10 file server to be upgraded and overwrite the
existing file. You should also copy the DSREPAIR.NLM and
overwrite the old file on SYS:\SYSTEM.
3. At the file server console of the server being upgraded (or
using RCONSOLE) toggle to the system console screen.
4. Enter the command "SET DSTRACE = *." and press <Enter> to
reload the Directory Services without downing the server.
5. Repeat the process for each 4.10 server in the network
which may be running the older version.
6. Although you do not have to upgrade all servers at once,
the DSREPAIR status commands will not report the status of
servers running the older version.
NOTE: Reloading the DS will not affect currently connected
users. Users who request new connections while the file server
reloads will, however, receive an error because the data base is
still closed. You may wish to perform the upgrade during a
period
of minimal user activity.
B. NEW INSTALLS OF NETWARE 4.1
Because it is not possible to copy the DS.NLM file to the
read-only CDROM one of the following processes must be used:
1. Staging Server (Preferred)
Many people copy the contents of the CDROM to another server's
magnetic disk drive and perform the install across the network.
Generally this provides high performance and
the ability to alter the files to be installed. If you use
this method you should copy the new DS.NLM to the
NW410\SYSTEM\PREINST directory.
Run the installation and the correct DS will be loaded and
activated.
2. Install or Upgrade from CDROM
The CDROM may be connected directly to the file server being
installed or upgraded or it may be attached to another file
server and accessed across the network.
BEFORE you begin the upgrade of the NetWare 4.0x server you
must first copy the new DS.NLM onto the file server in the
SYS:\system directory. Prior to NetWare 4.10 the DS was embedded
in the Operating System, so this will have no effect on the
operation of the server and may be done at any time before the
upgrade.
Begin the installation in the normal fashion. During the
"Preliminary file copy" the older DS.NLM would normally be copied
to the file server. When the install program detects
a newer version is already present it will display the file
name and ask "over write newer version?" Answer "NO" and
continue with the installation.
