A CV Batch job runs fine on most days but sometimes fails with an 1153 abend code.
In most cases re-running the job is successful.
What can cause an 1153 abend code?
CA IDMS, all supported releases.
The 1153 abend code can be caused by a corrupt index but it can also be caused by other things:
When specifying RETRIEVAL NOLOCK in the SYSGEN and a retrieval run unit reads a record being updated by another transaction.
When a retrieval run unit in local mode reads a record being updated by another transaction running under the CV or another batch job.
Change the SYSGEN to remove RETRIEVAL NOLOCK,
Try re-running the job when there is no or low update activity.
