TAA Tools
BACKUP CONSIDERATIONS


The following is recommended:

-   A full library save such as SAVLIB LIB(*ALLUSR) on a regular basis
    of the TAATOOL, TAASECURE, and TAAWORK libraries.

-   A full library save such as SAVLIB LIB(*ALLUSR) of any libraries
    (or files created in other libraries) associated with the TAA
    Tools.

-   A regular SAVSYS or SAVSECDTA to capture the TAA Authorization
    Lists and their authorizations.

-   If you use a SAVCHGOBJ approach on a daily basis, consider
    including the TAATOOL and TAASECURE libraries to capture any daily
    changes along with your other libraries. The amount of change
    activity from TAATOOL and TAASECURE should be none or very little.

If you are using a SAVCHGOBJ approach on a daily basis, the TAAWORK
library may be bypassed. This library only contains work objects which
do not need to be saved.

The following describes the major pieces that make up the TAA
Productivity Tools product and any unique backup considerations.


TAATOOL Library

The TAATOOL library contains mostly programs, commands, display files,
and model files (used to create physical files from). Very few of the
objects will have any changes made to them.

For example:

-   The QATTxxx source files in TAATOOL are intended to contain source
    you have copied out of the TAA Archive that you do not intend to
    change permanently, but want a copy for use in SEU copying or
    browsing. If a back level version is restored, the source could be
    copied out again (See the discussion on the HELPTAA menu for
    'Modifying a Tool').

-   The QATTDDS source file in TAATOOL will contain source if you have
    a demonstration license. This source is used to create files such
    as with the SPLARC tool.

-   The PRTDBFSRC source file in TAATOOL is intended to contain the
    source created by CRTPRTPGM (it is the default source file). By
    default, the member is removed after the program created.

-   Some data areas in TAATOOL are used for recovery processing while
    a tool is running.

With normal use, there will probably be few if any changes made to the
TAATOOL library on a daily basis. However, you have the capability to
modify tools and re-create them in the TAATOOL library. Any of these
types of changes should be backed up regularly.


TAASECURE Library

The TAASECURE library is used for security sensitive objects and
allows the Security Officer to make entries that control how other
tools are processed.

For example:

-   The data area ADPMBR is used by the ADPMBR tool to determine what
    files are valid for the use of a command such as ADDPFMADP.

-   The data area ACCSECLIB is used by the ACCSECLIB tool to determine
    what private libraries may be used by the ACCSECLIB tool.

-   The DSPPWD tool is designed to allow a capture of user passwords
    so that the actual passwords may be reviewed. The file containing
    the passwords is kept in TAASECURE. No entries will be made unless
    the Security Officer makes an overt act to implement the steps
    needed to activate the DSPPWD tool.

There will probably be few if any changes made to the TAASECURE
library on a daily basis. However, there are a few tools such as
DSPPWD and CHGUSRPWD2 where use of the tools require that you
re-create the tools with some objects being placed in TAASECURE. Any
of these types of changes should be backed up regularly.


TAAWORK Library

The TAAWORK library is used for various work objects. The library must
exist for certain tools, but the objects in the library are not needed
beyond an IPL. The tools that use the library provide for cleanup
functions.


TAA Authorization Lists

Several tools are security controlled by TAAxxx Authorization lists
that exist in QSYS. The use of Authorization Lists allows you to grant
authority to use various tools and retain the authority when a new
update or release of the TAA Productivity Tools is installed.

The system saves Authorization Lists in QSYS when SAVSYS or SAVSECDTA
is used. A regular use of these commands is recommended.

There will probably be few if any changes made to the TAA
Authorization Lists on a daily basis.


TAAINS and TAAINSLIC libraries

The TAAINS and TAAINSLIC libraries are used for installing the TAA
Productivity Tools. After the successful installation of the tools,
the libraries are automatically deleted. The libraries do not need to
exist permanently on your system and do not need to be backed up.


Other Special Install Libraries

During the install process, the TAAINS2 library is created on your
system. It will be automatically deleted if the product is
successfully restored. The library does not need to exist permanently
on your system and does not need to be backed up.

The TAATOOLZ, TAASECUREZ, and TAAINS2Z are restored as part of the
install process and deleted shortly after they are restored. They are
used to set the user attribute of the corresponding libraries. They
should not exist on your system if the product has been successfully
restored.


TAACMD Library

The TAACMD library is not a formal part of the TAA Productivity Tools
product. This is the recommended name for the library to contain the
commands if you want a separate library for the TAA commands.

A separate library is optional. See the discussion in 'Library List
Requirements' on the HELPTAA menu.

If you have such a library, it should be backed up as your own data.

There will probably be few if any changes made to the separate command
library on a daily basis.


TAAFILE library

The name TAAFILE is are not part of the TAA Productivity Tools
product. When the TAA tools of QUSRTOOL were being used, the TAAFILE
library was often used to contain the files required by certain tools.
When the TAA Productivity Tools product was introduced, the commands
that created files allowed the user to decide the library to be used.

If you are still using TAAFILE, you should review the objects. If they
are no longer being used, you may delete the library.

Some users may prefer to keep all TAA created files in a specific
library in which case any name may be used.


Other Tool Libraries

Certain tools require you to create libraries of specific names or
optionally require you to create such a library. Each tool that
requires such a library will normally discuss the backup
considerations.

For example:

-   The SPLCTL tool requires that you create the SPLCTLS and SPLCTLD
    libraries. These libraries will contain your data and will
    probably have a significant amount of daily changes.

-   The CHKSPELL tool (also the other tools involving spell checking)
    optionally allow the entry of a list of dictionaries. These
    dictionary lists (in the form of data areas) must exist in the
    TAADCT library. You must create the library and other objects in
    the library if you want to enter a list of standard dictionaries
    instead of using the default. There will probably be few if any
    changes made to the TAADCT library on a daily basis.


Created Files and Other Objects

Some of the tools support CRT or CVT commands that will create data
base files and other objects in a library that you specify. These
libraries should be backed up regularly as they will contain your
data.

The amount of change to the data will vary significantly depending on
the tool.


SAVTAATOOL ($$TAATOOL and Q$$TAATOOL libraries)

Because the TAA Productivity Tools can be helpful in a total restore
situation, some users may prefer to restore the TAATOOL and TAASECURE
libraries before restoring the normal set of libraries.

For example, the system commands RSTLIB LIB(*IBM) or RSTLIB
LIB(*NONSYS) require the restricted state. If you want to restore
without using the restricted state, RSTALLLIB may be helpful.
RSTALLLIB has been used to successfully restore without using the
restricted state, but since the function is not supported by the
system, you run at your own risk. There are no known problems.

RSTALLLIB has the additional benefit that it has both a beginning and
ending file sequence number as parameters on the command. Thus if you
have multiple tape devices and a high speed CPU, you can have multiple
restore operations in process at the same time.

The SAVTAATOOL tool requires that either the $$TAATOOL or Q$$TAATOOL
library be created by using the CRTSAVTAA command which is part of the
same tool. You then save to either library with the SAVTAATOOL
command. The intent of using these library names is that the libraries
would be saved at the beginning (or close to the beginning) of a tape
created by one of the special values for the SAVLIB LIB parameter.

For example, if you want to use the TAA Tools to help you restore the
system, you would choose one of the special libraries based on your
backup strategy.

-   If you use SAVLIB LIB(*IBM), you would use the Q$$TAATOOL library
    as the Q libraries are saved by the special value *IBM.

-   If you use SAVLIB LIB(*NONSYS), you would use the $$TAATOOL
    library as the libraries are saved in straight alphabetical
    sequence.

After restoring the SAVSYS media, configuration, and security data,
you would mount the SAVLIB media and call the TAASAVPC program in the
library you are using (either $$TAATOOL or Q$$TAATOOL) to restore the
TAATOOL and TAASECURE libraries. After restoring TAATOOL and
TAASECURE, the TAA Tool commands (such as RSTALLLIB) can then be used
to install the remainder of the libraries.

If you want to use the SAVTAATOOL approach, see the documentation
about the tool.
