HP Archive Backup System for OpenVMS Guide to Operations

System Backup to Tape for Oracle Databases
9.12 Support for Oracle RDB database
All other RMU commands that accept the /LIBRARIAN qualifier only use one writer thread or
one reader thread representing one archive data stream.
Note
RMU commands only support the retrieval of data using the /LIBRARIAN qualifier
that has been stored by other RMU commands using the /LIBRARIAN qualifier.
In addition to the /LIBRARIAN qualifier used with existing RMU commands, there are new
commands as follows:
$RMU/LIBRARIAN/LIST=(OUTPUT=disk:[directory]listfile.ext) FILENAME.RBF
RMU/LIBRARIAN/LIST command to list data streams stored using SBT that have been created
by RMU from a backup filename.
"/LIST" used alone will display to the default output device. If the "OUTPUT" option is used
output will be displayed to the specified file. All data steams existing in the SBT that was generated
for the specified backup name will be listed.
$RMU/LIBRARIAN/REMOVE=([NO]CONFIRM) FILENAME.RBF
RMU/LIBRARIAN/REMOVE command to delete data streams stored using SBT that have been
created by RMU from a backup filename.
"/REMOVE" deletes all data steams stored using SBT that were generated for the specified
backup name.
Warning
This command should be used with caution. The user should be sure that a more
recent backup for the database using SBT exists under another name before using this
command.
The "CONFIRM" option is the default. It will prompt the user to confirm that he wants to delete
the backup from the ABS. The user can then reply "Y(ES)" to do the deletion or "N(O)" to exit
the command without doing the deletion if he wants to confirm that a more recent backup for the
database exists in the SBT that was generated using a different backup name. The user must
specify the “NOCONFIRM" option if he does not want to be prompted. In this case the deletion
will be done with no confirmation prompt.
9.12.2 BACKUP/RESTORE Using PLAN Files
The /LIBRARIAN qualifier can be used for parallel backup operations where backup threads
can execute in multiple processes. The database backup command can be invoked as a parallel
command which uses multiple processes but the other RMU commands which accept the
/LIBRARIAN qualifier do not support parallel processes but execute in one process. RDB V7.1
SQL/Services is required to be installed for RMU parallel backup operations.
The following lines in the backup PLAN file used to specify the parameters for parallel backup
operations relate directly to ABS SBT.
Backup File = MF_PERSONNEL.RBF
Style = Librarian
Librarian_trace_file = FILE.TRACE
Writer_threads = #
The backup file name must be the same file name specified for the restore and the style must be
set to "Librarian" indicating a backup to the LIBRARIAN. "Librarian_trace_file
=FILE.TRACE" are optional parameters specified with the /LIBRARIAN qualifier and passed
