Fully-Optimized Rman Configuration For Tsm - HP 12000 Design Manual

The deduplication-optimized RMAN settings:
FORMAT 'df.%d.%f.<other_identifiers>' for each data file
FILESPERSET 1
MAXOPENFILES default
Number of channels does not impact deduplication performance, but does impact backup
performance so consider increasing the number of channels while maintaining concurrency at 1)
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE 'SBT_TAPE' TO
'%F';
Compression off
Encryption off

Fully-optimized RMAN Configuration for TSM

For larger or more complex Oracle (version 10 or higher) databases, the following RMAN changes
can be used to provide fully optimized deduplication for TSM with firmware version 3.4 and higher,
though the required changes are simplified for version 6.0 and higher. For version 3.4 with TSM,
to get optimum Oracle deduplication you can customize your RMAN scripts to add the additional
FORMAT information (for data files use FORMAT 'df.%d.%f.<other_identifiers>'), but
with version 6.0 and higher this FORMAT change is no longer required. With both versions 3.4
and 6.0, you must still disable multiplexing.
The deduplication-optimized RMAN settings:
Version 3.4 only:
FORMAT 'df.%d.%f.<other_identifiers>' for each data file
Versions 3.4 and 6.0:
FILESPERSET 1 (optional on version 6.0 but if you set this to greater than 1 you must set
MAXOPENFILES to 1
MAXOPENFILES default
Number of Channels defined in RMAN must equal the maximum number of mount points as defined
for your system
