When running a SARBCH job, the following messages were received:
IEF861I FOLLOWING RESERVED DATA SET NAMES UNAVAILABLE TO C726812Y
IEF863I DSN = XXXXXX.XXXXXX.SARTAPE.T0001659 C726812Y RC = 04 RSN = 00000000 FROM SERVICE ENQ
87 IEF458D C726812Y REPORT WAITING FOR DATASET. TO CANCEL WAIT REPLY 'NO'
SARTPI42 Tape allocation failed ERR=0484 INFO=0000 DSN=XXXXXX.XXXXXX.SARTAPE.T0001659
SARTPI44 DUPLEX Tape does not exist or does not contain file - TSQ=1659
What do the above messages mean and what would be the recommended corrective action?
All of the messages found in the batch job output involved the same tape being in use at the time of the job run.
The IEF861I messages indicate that a job requested the use of a dataset that was not available at the time, as the dataset was reserved for other jobs currently running in the system.
The IEF863I messages indicate that View tape ....SARTAPE.T0001659 was requested for use, but was not available.
The IEF458D messages indicate that the system was requesting a dataset that was in use by another job.
The SARTPI42 messages indicate that there was a dynamic allocation error in accessing tape ....SARTAPE.T0001659.
The SARTPI44 messages indicate that, as there was a problem accessing tape ....SARTAPE.T0001659, there was a switch attempted to use a duplex tape, however the client was not using duplexing, so no duplex tape was available as well.
A View backup was running during the time range of the messages and had control of the requested tape.
A suggestion was made to review the SARSTC log, for time ranges of the start and end of Phase 1 processing, and to run the batch job at a time when the backup did not have control of the tape.
