Converting to DFSMSrmm from ASG-ZARA or AutoMedia

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

F DFRMM,M=xx

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

 VOLSER

 Retention date or equivalent in the vendor product

 Assigned or creation date or equivalent

 Job name

 Volume sequence number

 Data set sequence number
