System Backup to Tape for Oracle Databases
9.12 Support for Oracle RDB database
Install the file as a shared known image. This associates a known image with the latest version of
the image file
$INSTALL REPLACE /OPEN/HEAD/SHARE
SYS$COMMON:[SYSEXE]MDMS$SBTSHR_NMA32.EXE
The default catalog and archive used by SBT for backup/restore are ORACLE_DB and
ORACLE_DB_ARCHIVE. You should create one oracle_db type catalog and an archive.
Use the following command to create a oracle_db type catalog:
$ MDMS CREATE CATALOG ORACLE_DB /TYPE=ORACLE_DB
Use the following command to create the default archive:
$ MDMS CREATE ARCHIVE ORACLE_DB_ARCHIVE -
/ARCHIVE_TYPE=TAPE -
/CATALOG=(NAME=ORACLE_DB) -
/MAXIMUM_SAVES=36 -
/MEDIA_TYPE=DLT_III -
/POOL=DB_BACKUP_POOL -
/RETENTION_DAYS=35
9.12.1 RMU Commands that accept /LIBRARIAN Qualifier
RMU/BACKUP command accepts the /LIBRARIAN qualifier to backup data using ABS SBT.
$RMU/BACKUP/LIBRARIAN=(trace=disk:[directory]tracefile.trace)/LOG DATABASE
FILENAME.RBF
RMU/RESTORE command accept the /LIBRARIAN qualifier for retrieving data using ABS
SBT.
$RMU/RESTORE/LIBRARIAN=(trace=disk:[directory]tracefile.trace)/LOG FILE-
NAME.RBF
FILENAME.RBF is the backup filename. The backup filename excluding the extension must be
the same name previously used for an RMU backup using SBT.
The RMU command used with the /LIBRARIAN qualifier cannot specify a list of tape or disk
devices. It accepts a backup file ("rbf file") name. Any disk or device specification or file extension
specified with the backup file name is ignored for the backup file name specified to the
archive. For example, "device:[directory]FILENAME.RBF" is specified as "FILENAME" when
the backup file data is stored in or retrieved from the archive. SBT writes trace data to the tracefile,
if specified.
The archive application is a "black box" to RMU and the backup file name is the identifier of the
stream of data stored in the archive. The MDMS utility used with the ARCHIVE BACKUP
SYSTEM is used to associate devices with the stream of data sent to or retrieved from the
archive by RMU. Since SBT is a black box to RMU that can store data to tape or disk, device
specific qualifiers such as /REWIND, /DENSITY or /LABEL cannot be used with this interface.
$RMU/BACKUP/LIBRARIAN=(WRITER_THREADS=2, trace=disk:[directory]tracefile.trace)/LOG
DATABASE FILENAM.RBF
Each writer thread for a backup operation or reader thread for a restore operation manages its
own stream of data. Therefore, each thread uses a unique backup file name generated from the
backup file name specified on the command line. A number is incremented and added to the end
of each backup file name specified to the archive (except for the first) representing a unique data
stream. This number is the equivalent of the volume number associated with non SBT RMU
backups and restores.
