Safeguards Utility

The Safeguards Utility is designed to provide a simple, easy way of adding or removing the CA Compress Safeguards. The Utility allows you to specify the CA Compress Control File that contains the names of the VSAM data sets under CA Compress's control and provides control statements that contain either a specific data set name or a pattern data set name to be used. The utility is useful when converting from an earlier release because it adds whatever Safeguards are missing from a data set. It can also be used to remove the Safeguards if it is necessary to run an earlier version of CA Compress that does not support them.

When the Safeguards Utility is invoked, it reads the SYSIN data set. The input can be either a pattern name or a specific data set name. If a specific data set is named, the Utility attempts to add or remove the Safeguards information from that data set without regard for its existence within the CA Compress Control File allocated to the VSAMFILE DD statement. If a pattern is named, it is stored for later processing. When the end of input on SYSIN occurs, the utility reads the VSAMFILE data set if there were any pattern data set names, trying to match each name from VSAMFILE with any of the patterns. If the match is successful, the Utility attempts to add or remove the Safeguards.

• The JCL for the Safeguards Utility is in YOUR.CAI.CCVBJCL(SGUJCL).
• The PARM can be either ON to add Safeguards to the selected data sets or OFF to remove them from the selected data sets.
• STEPLIB defines the library that contains the CA Compress load modules.
• VSAMFILE defines the CA Compress Control File that contains the names of the data sets you wish to process.

  The control statements are fixed format, with the data set or pattern name starting in column 1. A pattern name contains one or more special characters ("/", "?", "*" or "!"). For more information about these characters, see the CA Compress User Guide. A discrete data set name does not contain any special characters. To process all of the data sets in the VSAMFILE data set, use a pattern of / in column 1.
