Handling a checkpoint-in-doubt condition
One of the two checkpoints in the restart data set is always valid for restart. Under certain circumstances,
AR/CTL
may be writing the checkpoint to the restart data set when an abend or system failure occurs. At restart, if the checkpoint does not have a COMPLETED status,
AR/CTL
issues message BMC74301E to request manual intervention.
Before you can restart the job step, you must handle the checkpoint-in-doubt condition. The procedure depends on the DBMSs involved in application program execution. Part of the procedure is to issue the TOGGLE command on the Restart Data Set Information panel (which you access by selecting the restart control record with action code C). For more information about using the TOGGLE command, see Reference.
