System Backup to Tape for Oracle Databases
9.6 Using System Backup to Tape with Oracle's Recovery Manager
9.6 Using System Backup to Tape with Oracle's Recovery Manager
This section describes how to use SBT to backup your Oracle database. If you have configured
SBT correctly using the above steps, you are now ready to use SBT with Oracle's Recovery
Manager. How to use Oracle's Recovery Manager is described in Oracle's documentation. This
section describes what Oracle Recovery Manager command keywords and parameters affect
SBT.
The following topics are covered in this section:
• Specify SBT shared library
• Specifying an archive
• Specifying a catalog
• Specifying I/O block size
• Specifying archives for duplex backups
9.6.1 Specifying SBT Shared Library
9.6.2 Specifying an Archive
This is applicable only to Oracle9i Release 2 (9.2.0.2). Oracle9i Release 2 (9.2.0.2) has support
for shared libraries in RMAN. The SBT shared library must be specified as part of the RMAN
script for Oracle to load the sbt shared library.
run
{
allocate channel t1 type 'sbt_tape'
parms="SBT_LIBRARY=abs_sbt,
ENV=(MDMS$SBT_ARCHIVE=REG_RMAN_ARCH,
MDMS$SBT_IO_BLOCK_SIZE=65024)";
backup filesperset 4
database;
release channel t1;
}
In the above script SBT_LIBRARY is a keyword which is assigned the logical name abs_sbt.
Remember that abs_sbt is a system wide logical pointing to
SYS$SHARE:MDMS$SBTSHR_MA64_9I2.EXE. We defined abs_sbt to
SYS$SHARE:MDMS$SBTSHR_MA64_9I2.EXE in rdbms_logicals.com
If you do not specify SBT_LIBRARY params in the script, Oracle will not be able to load the
SBT shareable image.
Moreover params should be specified for each and every channel in the script.
In order to have SBT select the archive that you want, you must specify the archive in the Oracle
Recovery Manager allocate command. The archive is specified in the parms keyword for the
allocate command. Example 9–9 shows how to code an Oracle Recovery Manager script for the
archive OFFSITE_ARCH. The Oracle server creates the process logical
MDMS$SBT_ARCHIVE.
Example 9–9 Specifying the Archive in the Allocate Command
run
{
allocate channel t1 type 'sbt_tape'
parms="ENV=(MDMS$SBT_ARCHIVE=OFFSITE_ARCH)”;
backup tablespace system;
release channel t1;
}
