RDF System Management Manual for H-Series RVUs (RDF 1.8)

for certain that AA000007 will never be needed again. When this message is written, you
can start the backup process to dump AA000007 to tape.
3. When the backup process opens AA000007 and the backup is in progress, you can stop the
file-opening process run in Step 1. The purger will continue its attempts to purge AA000007,
but these attempts also will fail as long as the backup process has AA000007 open. Eventually,
when the backup is complete and AA000007 is successfully copied to tape, no processes will
have this file open. After this point, the purger will be able to purge AA000007 successfully.
Repeat the preceding steps for each image trail file you want to back up.
Making Online Dumps With Updaters Running
RDF/IMP, IMPX, and ZLT allow you to take dumps of the backup database while the updaters
are running. To do this, you use the UPDATEROPEN parameter of a SET RDF or ALTER RDF
command to specify the access mode (protected or shared) that all of the updaters use when
opening database files.
The default is protected access.
Protected access is strongly recommended, except when you specifically want to take dumps of
the backup database with the updaters running.
To take online dumps of the backup database while the updaters are running:
1. Stop the updaters (issue a STOP UPDATE command on the primary system).
2. Alter the UPDATEROPEN attribute of the RDF configuration to SHARED:
ALTER RDF UPDATEROPEN SHARED
3. Restart the updaters (issue a START UPDATE command on the primary system).
4. Initiate the online dump.
After dumping is finished, change the access mode back to protected:
1. Stop the updaters (issue a STOP UPDATE command on the primary system).
2. Alter the UPDATEROPEN attribute of the RDF configuration to PROTECTED:
ALTER RDF UPDATEROPEN PROTECTED
3. Restart the updaters (issue a START UPDATE command on the primary system).
Doing FUP RELOAD Operations With Updaters Running
Because the backup database is audited by TMF, you cannot do FUP RELOAD operations on it
unless you have set the updater access mode to shared by using the UPDATEROPEN parameter
of a SET RDF or ALTER RDF command.
The default is protected access.
Protected access is strongly recommended, except when you specifically want to do a FUP
RELOAD on the backup database with the updaters running.
To do a reload on the backup database while the updaters are running:
1. Stop the updaters (issue a STOP UPDATE command on the primary system).
2. Alter the UPDATEROPEN attribute of the RDF configuration to SHARED:
ALTER RDF UPDATEROPEN SHARED
3. Restart the updaters (issue a START UPDATE command on the primary system).
4. Initiate the reload.
After the reload is finished, change the access mode back to protected:
1. Stop the updaters (issue a STOP UPDATE command on the primary system).
2. Alter the UPDATEROPEN attribute of the RDF configuration to PROTECTED:
ALTER RDF UPDATEROPEN PROTECTED
