VSAM RLS hang conditions

Should a hang condition occur, you can generate dumps of the following spaces from all systems:

SMSVSAM address space
SMSVSAM dataspace
Catalog address space

The following is an example of how to generate a dump SYS01 for systems SYS01, SYS02, and SYS03:

   SYS01   DUMP COMM=(MULTI SYSTEM DUMP)
   SYS01   R nn,JOBNAME=(SMSVSAM,CATALOG),CONT
   SYS01   R nn,REMOTE=(SYSLIST=(SYS02,SYS03)),CONT
   SYS01   R nn,DSPNAME=('SMSVSAM'.SMSVSAM,'SMSVSAM'.MMFSTUFF),CONT
   SYS01   R nn,DSPNAME=('SMSVSAM'.*),END

To get all data spaces, use .* as the last line of the example shows.

You might need to dump one or more of the users' address spaces if it appears that they are involved in the hang condition.

IBM's Customer Support might request a report of the active threads. Invoke IPCS VERBX SMSXDATA 'F(AS) JOB(SMSVSAM)' to obtain a summary of TCBs running in the SMSVSAM address space and the users' requests that were active at the time of the failure.
