REPROCESS function description

Use the REPROCESS function to reinsert messages that have been processed into the shared and nonshared message queues.

If an application program has processed messages incorrectly because of a logic error, you can reprocess the messages after the program error is corrected.

Attention: Database batch backout or database recovery is required before using the REPROCESS function to avoid double updating.

You can locate checkpoints and mass-insert transactions into the IMS message queue by concatenating several system logs.

REPROCESS can be used for stress, regression, or application testing an IMS system in both the shared and nonshared queue environment.
