CA Disk Parameter Library (PARMLIB)

The control parameters that CA Disk uses, provide the following information for processing:

• How CA Disk operates
• The format of reports
• Data sets that CA Disk is to skip processing for
• Provide user-dependent information to CA Disk functions

These parameter lists are specified as members of a partitioned data set known as the parameter library (PARMLIB). The PARMLIB implementation allows CA Disk to tailor its operation to your requirements. The contents of a PARMLIB member can be easily changed. After they are changed, the next execution of CA Disk uses them.

The parameter library is ready to use as it was loaded from tape. Do not change the supplied members. The supplied members are parameter lists that are used for internal CA Disk system functions. The members are replaced with each new release. You can place parameter information, for your installation and users, in a new member of the parameter library that you create.

For more information about common CA Disk parameter lists and the purpose of each, see CA Disk Libraries in the Systems Guide.

For the remainder of the installation process, only the following two members of PARMLIB are of primary concern:

• SYSPARMS

  SYSPARMS indicate your processing options to CA Disk. See the Sysparms section in the Systems Guide for all available system parameters.

  For example, the default retention period for data sets being archived is 30 days. To change the 30 days to 120 days, create a member that is named SYSPARMS in the PARMLIB data set. Add one line that contains ARCRETPD0120 or one line with RETRETPD0120. Optionally you can add both lines.

• FILEDEFN

  FILEDEFN defines the internal attributes of the CA Disk FILES data set (FDS).

  Because the CA Disk parameter library is a partitioned data set, it can be updated like any other PDS.
