The Save TAATOOL Libraries command is intended for those users who
want to restore the TAA Productivity Tool early during a disaster
recovery. This allows the TAA Productivity Tools to be used to
assist in restoring the rest of the system.
* If your disaster recovery solution is *
* to restore all of the libraries (both *
* system and user) before using any of *
* the TAA Productivity Tools, you should *
* not consider SAVTAATOOL. *
The TAA Productivity Tools such as RSTALLLIB, RSTMNYLIB, and
RSTALLCHG can be used to improve your critical recovery needs by
allowing you to do selective restores or restore multiple libraries
whether the tapes were created with a LIB(*nnn) on the save commands
SAVTAATOOL can be used with either of two special libraries $$TAATOOL
or Q$$TAATOOL. These will be described as 'backup libraries'. Save
files are used in the backup libraries to save the TAATOOL and
TAASECURE libraries. The use of the special library names allows the
library containing the save files to be restored by a single RSTLIB
command (this does not restore the TAATOOL or TAASECURE libraries).
The special TAASAVPC program (exists in the backup libraries) can
then be used to restore the TAA Productivity Tool libraries from the
save files. The TAA Productivity Tool commands can then be used to
restore the remainder of the system.
The TAAWORK library is not saved by SAVTAATOOL. The TAAWORK library
is used by various tools for temporary work objects. The typical
tools you would use to help restore the system do not use TAAWORK.
To determine whether to use $$TAATOOL or Q$$TAATOOL as your backup
library, you must first consider your save/restore strategy.
** The $$TAATOOL library is intended for those users who use
SAVLIB LIB(*NONSYS) or the Operational Assistant option to
save the entire system. When *NONSYS is used, both user and
system libraries are saved in alphabetical sequence. Using
the name $$TAATOOL will place that library at or near the
beginning of the tape. If the Operational Assistant option
was used, the library will be after the libraries saved by
** The Q$$TAATOOL library is intended for those users who use
SAVLIB LIB(*IBM) and then SAVLIB(*ALLUSR). Using the library
name Q$$TAATOOL will place the library at or near the
beginning of the SAVLIB(*IBM) tape. SAVLIB LIB(*IBM) saves
all Qxxx libraries that are not in a specific list.
To successfully use the SAVTAATOOL approach, you must properly save
the backup library and the save files. The default on the SAVLIB
commands is SAVFDTA(*YES). This must be used to allow for a restore.
To use the SAVTAATOOL function as intended will require save files to
exist in your backup library with compressed versions of the TAATOOL
and TAASECURE libraries.
** For a CISC system (prior to V3R6), this will require
approximately 50 MB.
** For a RISC system (V3R6 and after), this will require
approximately 90 MB.
Once you decide which special library you want to use, a user with
*ALLOBJ special authority must use the CRTSAVTAA command to create
the required library. For example, to use the Q$$TAATOOL library,
the following command should be run (it is a short running command):
When the command completes, the library will exist with the save
files TAATOOL and TAASECURE plus the special restore program
TAASAVPC. Note that the libraries have not been saved.
Any user with *SAVSYS authority can then use the save command such
to save the libraries to the save files. This is a long running
command and should be submitted to batch.
SAVTAATOOL determines which library ($$TAATOOL or Q$$TAATOOL) is
being used, ensures the proper objects exist, and saves the TAATOOL
and TAASECURE libraries in a compressed format to the save files.
You may want to consider using SAVTAATOOL periodically to ensure that
the libraries are current. See the later discussion on use of
The CRTSAVTAA command may also be used anytime the objects must be
re-built. See the later discussion on changing the TAASAVPC program.
Automatic SAVTAATOOL on Install of TAA Productivity Tools
When the TAA Productivity Tools are installed and either the
$$TAATOOL or Q$$TAATOOL exist, a job is automatically submitted to do
SAVTAATOOL. This occurs when any update or new release of the
product is installed.
This ensures that the new version is properly saved in the backup
During the install processing, a check will be made for the TAASAVPC
program in the backup libraries. If the program exists, the new
version of the program will replace the existing version.
Restoring from $$TAATOOL or Q$$TAATOOL
In a disaster recovery situation, you would normally install the LIC
(Licensed internal code) and then i5/OS. Then there are important
steps such as:
At the point where you are ready to restore:
- The remaining system libraries from a SAVLIB(*IBM)
- Restore from a SAVLIB(*NONSYS)
is when you would typically want to restore the TAA Productivity
The library you selected ($$TAATOOL or Q$$TAATOOL) would normally be
restored by the normal RSTLIB command such as:
Assuming your save strategy is consistent with your backup library,
the backup library should be at or near the front of the saved media.
Once the library is installed, a user with *ALLOBJ special authority
should call the TAASAVPC program in the specified library.
For example, if you created $$TAATOOL, the command would be (the
command could be submitted to batch if a batch subsystem is running):
This will restore the TAATOOL and TAASECURE libraries.
The TAA Productivity Tool commands may then be used to assist in
restoring the remainder of the system. All of the product including
the commands, command help text, the HELPTAA menu, and documentation
would then be available.
If you have a tape from SAVLIB LIB(*xxx), the first file (sequence
number 1) contains a list of libraries that is used by the
corresponding RSTLIB SAVLIB(*xxx) function. To use a TAA
Productivity Tool command like RSTALLLIB, you must specify SEQNBR(2)
to start with the first library after the special first file.
Use of a Command Library for TAA Tool Commands
If you are using a command library for TAA Tool commands such as
TAACMD, you do not have to save or restore the library to use the
SAVTAATOOL concept. All TAA commands are always in the TAATOOL
library. You must have the TAATOOL library on your library list when
using a command like RSTALLLIB for disaster recovery.
Normal saves of the TAATOOL and TAASECURE libraries
If you follow the intent of the SAVTAATOOL function, there should be
no reason to backup the TAATOOL and TAASECURE libraries thru the use
of SAVLIB LIB(*NONSYS) or SAVLIB(*ALLUSR). You may use the OMITLIB
parameter to omit the libraries.
If you save the libraries on the normal save media (without using
OMITLIB), the following considerations exist if you first restore
from the backup library.
** The system RST commands will probably operate successfully and
restore over the top of existing objects in TAATOOL and
TAASECURE. If the the same version of the libraries is
restored, there should be no difference. If the versions
differ, there may be error conditions that would have to be
** If the TAA Productivity tool commands RSTALLLIB, RSTMNYLIB, or
RSTALLCHG are used, the TAATOOL library is automatically
bypassed because the program that is running is in TAATOOL.
The TAASECURE library would be restored over the existing
Use of SAVTAATOOL
Each time SAVTAATOOL is used, the command determines that the proper
objects exist in either $$TAATOOL or Q$$TAATOOL and then saves the
TAATOOL and TAASECURE libraries in a compressed format to save files
in the backup library.
In some unique situations you may want to use both libraries. If
both libraries exist, both will be saved to.
You would normally want to include the SAVTAATOOL command in a
regular backup procedure to ensure that any changes in the TAATOOL
and TAASECURE libraries are backed up.
A previous section has discussed the use of the automatic save that
occurs during the install of a new update or release of the TAA
Productivity Tools. This ensures that at least a base level version
of the tools will exist.
See the discussion on the HELPTAA menu of 'Backup considerations' for
the types of changes that can occur in the TAATOOL and TAASECURE
libraries. The major reason for a change in the TAATOOL library
would be if you re-created one of the tools.
Tailoring the TAASAVPC restore program
In most cases there should not be a need to tailor the special
If you do, follow the instructions for 'Modifying a tool' on the
You should re-create the new version in the TAATOOL library and then
CRTSAVTAA will ensure that the proper save files exist and create
them if they do not. It will also delete the current version of the
TAASAVPC program and duplicate the version from TAATOOL.
Note that during install of a new update or release of the TAA
Productivity Tools, the latest version from the TAATOOL library of
TAASAVPC will be placed into your backup library. Therefore, if you
have modified the TAASAVPC program, you must go thru the steps again
to re-create the tool and then use CRTSAVTAA to get your tailored
version of the object into your backup library.

There are several restrictions discussed throughout. The following
are the major considerations.
** The backup library chosen must be consistent with your save
** SAVFDTA(*YES) must be specified (or defaulted to) on your
normal backup such as SAVLIB LIB(*NONSYS).
** Only a user with *ALLOBJ special authority can use CRTSAVTAA
to create or refresh the backup library objects.
** Only a user with *SAVSYS special authority can use the
