Integrating Oracle and Data Protector
Backing Up an Oracle Database
Chapter 164
2. Allocate the Oracle channels.
Allocating a channel tells RMAN to initiate an Oracle Server process
for backup, restore, or recovery on the Oracle target database. For
example:
allocate channel 'dev_0' type 'disk';
or
allocate channel 'dev_1' type 'sbt_tape';
where you specify the backup directly to disk in the first case and
directly to tape in the second case. Note that if Data Protector is
linked with Oracle, Data Protector will perform the backup to the
tape in the second case.
If you specify more than a single allocate channel command,
RMAN will establish multiple logon sessions and conduct multiple
backup sets in parallel. This “parallelization” of backup and restore
commands is handled internally by RMAN.
IMPORTANT On Windows, a maximum of 32 or 64 (if device is local) channels can be
allocated.
To use Data Protector backup media, specify the channel type
SBT_TAPE.
3. Specify the parms operand:
parms'ENV(OB2BARTYPE=Oracle8,
OB2APPNAME=<DB_NAME>,OB2BARLIST=<backup_ specification_name>)';
Note that the RMAN script will not work without the above
parameters being specified in this form.
4. Specify format:
format '<backup_specification><<DB_NAME>_%s:%t:%p>.dbf'
Note that %s:%t:%p and the Oracle database name are required,
whereas the backup specification is recommended.
