===================================================
1 SWAPPER TECHNOLOGY
===================================================
1.1 What is it?
Norton Utilities Administrator (NUA) comes with two versions of
each of it's agents. Both versions of the programs are
identical, but the default versions have had a special
"pre-loader" attached to them. This "pre-loader" is called the
Swapper.
The Swapper allows the agents to run from a login shell with much
less memory than would normally be available. It does this by
"swapping" the login shell itself out of conventional memory,
executing the agent, then swapping the login shell back into
memory.
The Agents will automatically choose where to swap. The order of
preference is Extended (XMS) memory, Expanded (EMS) memory, then
Disk. These defaults can be modified with command line switches.
The file names of the Swapping Agents are:
NDDNET.EXE
NARESCUE.EXE
1.2 Non-Swapping Agents
The Swapping Agents may not be of benefit in all network setups.
For this reason non-swapping versions of each agent have also
been provided.
The file names of the Non-Swapping Agents are:
NDDNETB.EXE
RESCUEB.EXE
1.3 When is it useful?
Novell Netware:
The swapping agents are most useful in a Novell Netware
environment. The best way to run the NUA Agents is directly from
the system login script. Without the swapper technology, the
memory available for NDD and Rescue to run in would be limited by
the 150K overhead of the Netware login shell. With the swapping
agents, this 150K overhead is eliminated and the Agents should
never face memory limitations.
MS Lan Manager and IBM Lan Server:
Lan Man and Lan Server run external programs in an unusual manner
that limits the full potential of the swapper technology.
Instead of swapping out the entire 200K NET shell, only a small
6-10K stub of the command processor will be swapped.
Running the agents from a batch file after login (as mentioned in
the manual) may be a better solution to low memory conditions in
these environments.
Banyan Vines and Dec Pathworks:
Running the agents from a batch file after login (as mentioned in
the manual) may be the best solution to low memory conditions in
these environments.
1.4 Additional Switches
The following switches are available to control the swapping
versions of the agents.
/SWAP:n Force Swapping to use the following type of storage
Where n is: E for EMS
X for XMS
D for Disk (/TEMP is also required)
/TEMP=dir Where dir is the name of the directory where the
temporary swap file will be created. Disk swapping
will not occur without the TEMP switch being defined.
/SKIPHIGH Do not use upper memory
This switch should only be used on the non-swapping
agents.
/NOEMS Do not use EMS memory
/NOXMS Do not use XMS memory
/NOFRAME Do not use the EMS Page Frame
===================================================
2 LIMITATIONS OF THE AGENTS
===================================================
2.1 Minimum Memory Requirement to Run Each Agent
AGENTS REQUIRED MEMORY
NDDNET.EXE 375 KB (swapping version)
NARESCUE.EXE 360 KB (swapping version)
NDDNETB.EXE 360 KB + Login Shell overhead
RESCUEB.EXE 345 KB + Login Shell overhead
Please note that if you are running from a login script or shell,
you will need additional memory to make up for it's overhead. If
you use the swapping versions of the agents, this overhead can
often be eliminated.
===================================================
3 DISK DOCTOR AGENT
===================================================
3.1 Undo Files
The Disk Doctor agent can be configured to create an Undo File
every time a repair is made. The files are stored in a directory
off of the DATA directory. (Usually this directory is
NADMIN.UTD) Since these files can be quite large, and since UNDO
files are only useful if no changes have been made to the
repaired disk, they are automatically deleted after 30 days.
If an UNDO file exceeds the size of a single floppy disk, the
Create Undo Disk option in the NUA Console will not work
normally. Instead it will display the full network pathname of
the Undo file. Make note of this name. Create a Rescue Disk
which will contain Norton Disk Doctor. Run NDD on the
workstation with the problem, and choose the UNDO option. The
Undo file can then be retrieved directly from the network.
3.2 Compressed Drives
Testing the compression structures of a compressed drive
(especially very large Stacker volumes) can sometimes be a
lengthy process. If a particular workstation experiences
excessive delays, try running a defragmentation program such as
Norton Speed Disk. Alternatively, the Compression Structure
tests for that workstation can be disabled.
Norton Utilities Administrator fully supports compressed volumes
created with Stacker 2.0, Stacker 3.0, Stacker 3.1, SuperStor
2.0x, SuperStor Pro 1.0x, DR-DOS 6 SuperStor, Novell DOS 7
Stacker, IBM DOS 6.1 SuperStor/DS, and MS-DOS 6.x DoubleSpace.
Do not attempt to run the Disk Doctor agent on volumes created
with other disk compression utilities.
The NUA Disk Doctor Agent does not fully support Stacker 4.0, and
will not attempt to test or repair a Stacker 4.0 volume. It is
possible to disable testing of the compression structures. This
will allow testing and repair of the DOS disk stuctures. Running
the surface test on a Stacker 4.0 volume is not recommended.
3.3 Unsupported Drive Types
The NUA Disk Doctor Agent will not test floppy drives, removable
drives (such as Bernoulli or Sydos), or Ram drives.
===================================================
4 RESCUE AGENT
===================================================
4.1 Norton Utilities files needed to make Rescue Disks
When creating a Rescue Disk from the Console, NUA will search for
a copy of Norton Utilities. If Norton Utilities is not found in
the path, programs such as Norton Disk Doctor, Unerase, and
Rescue will not be available on the Rescue Disk.
4.2 Adding Network Drivers to RESCUE.INI
It is possible to configure the Rescue Agent to backup the
network drivers from each workstation. Since configurations and
driver names vary widely, sample sections have been left as
comments in the RESCUE.INI file contained in the DATA directory.
Review and modify the commented sections in the [NADMIN-SETUP]
and [INCLUDE] sections to suit your specific needs.
Refer to the manual for more information regarding the
RESCUE.INI file.
===================================================
5 UNINSTALL
===================================================
5.1 Location of NUA
When the Uninstall program is run, the directories that NUA is to
be removed from must be specified manually. Use the browse
buttons to select the drive and directories that NUA was
installed in.
5.2 The Data Directory
When the Uninstall program is complete, some files in the DATA
directory may not have been deleted. The file storage directory
(usually NADMIN.UTD) and it's contents should be deleted
manually.
===================================================
6 NOT FOR RESALE VERSION AND THE 10-USER PACK
===================================================
6.1 Ten Record Limitation
The "NFR" version and the 10-user pack of NUA has as built-in
limitation of ten records in the database. Once ten workstation
records have been added to the database, the Agents will report that
they can not run on any additional systems. To upgrade to a version
beyond 10 users (either for the NFR or 10-user pack) please contact
your Symantec Products representative.
===================================================
7 MISCELLANEOUS
===================================================
7.1 Problems with Memory Managers
If your system uses an advanced memory manager such as QEMM,
386Max, or MS-DOS 6.x EMM386, proper configuration can eliminate
many problems.
Fortunately, these memory managers provide utilities that
automatically optimize the memory manager's configuration. Use
this optimization program to configure your memory manager for
efficient and trouble-free use.
The optimizers for each of these memory managers are:
QEMM - OPTIMIZE
MS-DOS 6.x EMM386 - MEMMAKER
386Max - MAXIMIZE
Please refer to the memory managers' documentation for more
information.
7.2 Problems Detecting the Data Directory
If the NUA Agents report that the Database and Configuration
files can not be located, check the contents of the NADMIN.DAT
file located in the AGENTS directory. The "DataLocation=" line
in this file should show the full UNC pathname to the Data
Directory. Example:
[Options]
DataLocation=\\server\[volume]\pathname
