CA Dynam for VSE User Guide

Using Cataloged Information
Example:
// JOB DAILY REPORTS
// TLBL IJSYSBK,'CA Dynam/T BKUP',,,,,,2
// DLBL WORK1,'WORK FILE',O,SD
// EXTENT SYS001...
// EXEC DYNCAT,SIZE=128K
BACKUP
SCRATCH
/*
/&
This job stream produces all required daily reports. It first backs up the
Catalog file and verifies its integrity. Then it returns all eligible volumes to the
SCRATCH pool. It also provides the following:
• A list of all scratched tapes
• An exception list
• A list of all active data sets and their associated volumes in alphabetic
sequence
• A list of all volumes in numeric sequence
The sequence in this example is highly recommended; the backup step
ensures that you will be notified of any errors found in the Catalog. It also
produces a tape file from which you can rebuild the Catalog if necessary.
Use only the DYNCAT BACKUP command to back up the Catalog. No other
utility or user-written program properly resolves the internal pointers used in
the Catalog file.
Reporting Exceptional Occurrences
CA Dynam/T enables you to record exceptional occurrences. You can report
these occurrences upon request or whenever the DYNCAT SCRATCH command
is performed.
Also, transactions can be logged to the audit file and can be reported upon
using AUDTUTIL.
Exceptional occurrences include the following:
• Manually cataloging a version of a data set
• Returning a tape which has not been initialized under CA Dynam/T to
SCRATCH status
• Using a CA Dynam/T initialized scratch tape as output for an uncontrolled
file (generation option)
