OB8116: DANGER - Insufficient SQA, command aborted when entering the OMEGAMON PEEK command

Question & Answer


Question

When I enter the OMEGAMON PEEK command, I receive the following error:
OB8116: DANGER - Insufficient SQA, command aborted
My system appears to be running ok and is not having SQA shortage issues.

Answer

The PEEK command requires below the line csa or sqa storage to gather the requested data. This is the logic:

If the job is non-swappable, then use cross-memory code path which uses CSA storage to process the request.
If the job is swappable or the cross-memory code failed, then use the SRB code path which uses SQA storage to process the request.
The amount of csa or sqa storage required is defined by the PEEK WSIZ minor command. That value is also maintained in the .SET command as PEEKSIZE. OMEGAMON will need to allocate about 12K more than the WSIZ specification. The default WSIZE value is 32K, therefore by default 44K of csa or sqa is needed. You can issue the SYS CSA and SQA commands to determine the amount of csa/sqa available on your system. On the right hand side of the screen you will see the Largest Free Blk column which shows the amount of storage available. If your WSIZ specification is larger than the amount of available storage, then the OB8116 error is displayed. In order to successfully issue the PEEK command, lower the WSIZ value to an amount that is available on your system. You can restore the original WSIZ value when more csa or sqa becomes available or after the next IPL. Below if sample output of the commands mentioned above.
