Timid users

I am migrating from z/OS v1.4 to z/OS v1.7. I have applied the maintenance to TERASAM for the migration. I need the users to test, but they are afraid to run the segment definition job, because it as been a very long time since it has run. They would like another to test the migration fixes without necessarily re-assembling the segment table. Is there a way to do this? The users do not like the fact that all of the datasets both production and test are in the same assemble. Is there another method of separating the test and production datasets? Thank you.

I can think of 2 ways off the top of my head.

1: Use the TeraSAM SEGDEF utility for your test data sets. This uses Catalog control, marks the excpexit field of the data set & uses that to identify candidate data sets to TeraSAM. This would mean you would need to have TeraSAM enabled with CONTROL=BOTH - meaning use segment tables and catalog control.

2: You can also use a Test Segment Definition table.

Your test jobs would need the //SEG@nnnn DD statement as described in the manual above.

Does that help?

David,

I do think this would help. Can I turn Catalog=BOTH on when I next enable TERASAM? I will start my research now.

These methods also work for TSM 3.2.3.

Yes, a subsequent enable with control=both would work.

I attached 2 files as examples.

Best regards,

Both TS$SDF and SEGDEF as described by Dave Yates will work. But if the current implementation is with SEGTAB, use the test segtab as in the example SEG@xxx attached by Dave. Don't forget to include //SEG@xxx DD DUMMY to the job step. This will make TeraSam search for segtab SEG@xxx.

Here's an example TeraSAM table (attached).
