execution of the command. Only when the user confirms the command execution will the command
includes or excludes the file specified.
NOTE: The RDF administrator must ensure that the data of the files included or excluded must be
consistent. The ALTER command will neither ensure data consistency of files being included or
excluded nor it will report or correct any data inconsistency that the execution of the ALTER
command. In an emergency, if RDF initialization is not possible, HP recommends that you use the
ALTER command to modify the INCLUDE/EXCLUDE clause while RDF is running. INCLUDE/EXCLUDE
and INCLUDEPURGE/EXCLUDEPURGE are performed best during RDF Initialization.
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.
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) can affect updater
performance.
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.
To change the primary and alternate CPUs of a reverse trigger to CPUs 3 and 4, enter an ALTER
TRIGGER CPU command:
]ALTER TRIGGER REVERSE CPUS 3:4
To modify the INCLUDE/EXCLUDE clause for the MAT updater while RDF is running, enter an
ALTER VOLUME command with either the INCLUDE/EXCLUDE keyword.
] ALTER VOLUME $DATA01 INCLUDE SUBVOL.FILE
You may lose data consistency, Are you sure you want to proceed [Y/N]? y
]
In the example, $data01 is the master volume.
For an auxiliary updater, ATINDEX is a mandatory argument. If the option ATINDEX is not specified,
then the default value 0 is used will be taken and volume will be considered as MASTER volume.
] ALTER VOLUME $DATA02 ATINDEX 1 INCLUDE SUBVOL.FILE
You may lose data consistency, Are you sure you want to proceed [Y/N]? y
]
In the example $data02 is an auxiliary volume.
The ALTER VOLUME command supports inclusion/exclusion of files. This command does not support
wildcard in subvolume names and file names.
