For scenario 1:
This problem occurs most often after a new installation or an upgrade of CA Dispatch, but this problem is not limited to these situations.
This problem is likely the consequence of having the cai.CADSOPTN file (formerly PPOPTION) allocated with block size larger than 3120.
Check the DCB attributes for the CADSOPTN file and ensure it is allocated with LRECL=80, RECFM=FB and BLKSIZE=3120.
Having the option file blocked with 3120 is mandatory.
For scenario 2:
Receiving these S878-10 or S80A abends can indicate the CA Dispatch is running short of internal IDMS LSQA storage which is the area of storage used for processing reports and maintaining Bundles.
Clients who run the CA Dispatch started task with a REGION setting that is too high may encounter these types of abends. It a common abend for clients who, for example, specify their CA Dispatch region as REGION=0M. CA recommends NEVER setting a value of 0M for the CA Dispatch region.
For more information on tuning the CA Dispatch region, please refer to Knowledge Document ID: TEC504770.
