Chapter 7. Parallel running and validation 335
5. DFSMSrmm is now running with the journal data set disabled and the
EDGHSKP PARM(VRSEL) job can start. Running EDGHSKP without
journaling also reduces the execution time.
7.3.3 Enabling the journal data set
When the EDGHSKP run is complete, the journal data set should be activated
again. To activate the journal data set do the following:
1. Restart DFSMSrmm with the EDGRMMxx PARMLIB member, with the
command shown in Example 7-34.
Example 7-34 Restarting the DFSMSrmm subsystem
2. Backup the DFSMSrmm CDS and the journal data set, with the EDGHSKP
PARM(BACKUP) utility.
DFSMSrmm journal data set is now active, nullified, and synchronized with the
DFSMSrmm CDS after the backup.
7.4 Validating DFSMSrmm operation
In this section we show how to validate the DFSMSrmm operation. During the
validation phase of the conversion process, you must create reports to compare
and verify the correct conversion of the database and policies. We will explain
how to obtain reports that are useful for product comparisons.
7.4.1 Data set name list of non-scratch volumes
In both tape management systems, you should produce a list of the data sets for
every non-scratch volume. This list should include:
Data set name
Retention date or equivalent in the vendor product
Assigned or creation date or equivalent
Job name
Volume sequence number
Data set sequence number
