Command Overview
If you need to change an updater’s image trail volume, it is recommended that you stop
TMF; wait for RDF to stop; delete the volume; re-add the volume back into the
configuration, associating it to a different image trail volume; and then restart the TMF
and RDF subsystems. This is the only way to ensure that the backup database will
remain synchronized with the primary database.
Examples
To change the priority at which an extractor process is currently running, issue an
ALTER EXTRACTOR PRIORITY command. For example, the following command
changes the execution priority of the master extractor process to 170:
]ALTER EXTRACTOR PRIORITY 170
The following command changes the execution priority of the auxiliary extractor process
associated with the auxiliary audit trail $AUX02 to 170:
]ALTER EXTRACTOR ATINDEX 2 PRIORITY 170
To change the primary and backup CPUs for the master receiver process to CPUs 3 and
4 respectively, enter an ALTER RECEIVER CPUS command:
]ALTER RECEIVER CPUS 3:4
Remember you cannot do this particular alter operation while RDF is running.
Note. Altering the RDF UPDATERDELAY value is not recommended unless you have a very
specific reason for doing so; any value less than the default (10 seconds) may affect updater
performance.
