You may need to update your vital record specifications, either
to exploit a new function available in the latest release or to make
policy changes based on the needs of your business. You can perform
these steps to ensure that these changes go smoothly.
- Before updating your vital record specifications, back up your
DFSMSrmm control data set using EDGBKUP or EDGHSKP.
- Perform cleanup on the name vital record specifications by making
sure that any retention information in them is correct. DFSMSrmm provides
the EDGRVCLN REXX exec described in EDGRVCLN REXX procedure to clean up vital record specifications to report and clean up problems with name vital record specifications.
- Run DFSMSrmm inventory management vital record processing so the
DFSMSrmm control data set reflects the cleanup you have done.
- Make sure that all systems sharing DFSMSrmm control data sets
have the same parmlib options.
- Run the inventory management VERIFY function against
the control data set without introducing any of the new vital record
specification functions. When you run VERIFY, changes are not actually
made to the DFSMSrmm control data set so that you can look at the results
before any changes are made. The changes that would have been made
on a non-VERIFY run are included in the REPORT file and written to
the ACTIVITY file.
- Inspect the inventory management VERIFY ACTIVITY file by looking
at changes in matching vital record specification information, vital
record status, and retention date. DFSMSrmm provides a sample job
EDGJACTP that you can use with DFSORT to format and print fields in
the ACTIVITY file. Verify that the ACTIVITY file records reflect
only the changes you have made. If no changes have been made, the
ACTIVITY file should be empty. If there are entries, run EDGJACTP
from SAMPLIB and look at the summary files. Look in particular at "VRSS DD Statement - summary by status". Verify the data sets that
changed from V/R to not V/R retained or vice versa. The details of
why it changed is shown in "VRS DD Statement - data sets with changed
V/R status". The reports produced in other DD statements will also
be of interest. Be sure to review each of the summary and detail files
to understand the changes that would have been made.
- Correct vital record specifications as needed to make sure that
the policies you want are in place.
- Continue running the VERIFY function and inspect the results until
you get the results you expect using the new functions
- Begin defining and updating vital record specifications
to use new or different options and retention. We suggest starting
slowly until you gain more experience with using the new vital record
specification functions. We recommend using the RMM ISPF dialog to
add the new vital record specifications or to make changes to existing
vital record specifications. The kind of changes you make might include
VRS release options, use of COUNT(0), exploit the OPTION GDG of parmlib,
consolidation to generic data set name masks, or cleanup of unused
VRSs or VRS chains.
- Repeat the process from step 5 and step 9 until you are satisfied
that the results are what you expect.
- Run inventory management production run processing.
- Check the vital records retention report to make sure that data
sets and volumes are retained as you intended.
