The ALTERPRI command allows you to alter the priority of queued
requests for some DFSMShsm functions. You can alter the priority of
queued requests by the request number, by the userid that issued the
request, or by the data set named in the request. You can alter the
priority to make the request either the highest or lowest priority
in its queue.
You can use the ALTERPRI command to alter the queueing priority
for the following types of requests:
- ABACKUP
- ARECOVER
- BACKDS
- BACKVOL
- DELETE
- FRBACKUP
- FREEVOL
- FRRECOV
- MIGRATE
- RECALL
- RECOVER.
You cannot alter the queueing priority of BACKVOL CDS commands
and requests that have already been selected for processing.
Use the ALTERPRI command on an as-needed basis only. The ALTERPRI
command only works for queued requests and will have no effect on
any new requests.
Note: - To reprioritize a request on the Common Recall Queue, enter the
ALTERPRI command on the same host that originated the recall request.
- The BACKVOL STORAGEGROUP, BACKVOL VOLUMES, FRBACKUP DUMP, FRBACKUP
DUMPONLY, and FRRECOV DSNAME commands, and requests for single volume
recovery from incremental backups, each generate multiple requests
(one request per volume), all with the same request number. Therefore,
an ALTERPRI REQUEST command entered for one of these requests will
alter the priority of all requests generated for the command.
- This command is security protected, so a security profile must
be defined and users must be given access to it before the ALTERPRI
command can be issued. For information about defining FACILITY class
profiles, see z/OS Security Server RACF Security Administrator's Guide.
