Manual Balancing - HP Data Protector A.06.11 Integration Manual

• RMAN stores information about backups in the recovery catalog. For security
reasons, keep the catalog in a separate database. This requires more
administrative work.
• In a disaster situation (such as the loss of a production database and recovery
catalog), the restore and recovery of data is complicated. It may be impossible
without the help of Oracle Support. If the Recovery Manager does not have
administrative data stored in the recovery catalog, it cannot recover the database
only by using the backups that have been made.
• For each RMAN channel, set the SBT_LIBRARY parameter to point to the correct
platform–specific Data Protector MML. For details on the Data Protector MML
location, see
If RMAN is used through the BRBACKUP utility, consider the following:
• The recovery catalog is not used. Information about backups is saved in the control
file and SAP R/3 log files. After each backup, the control file and SAP R/3 log
files are saved. When data is restored, the control file is copied back first, followed
by data files. In case of a disaster, restore SAP R/3 log files before you restore
any data files.
• Other important files will still be automatically backed up using the backint
program.
• All previous SAP R/3 backup strategies can still be used with RMAN. However,
RMAN cannot be used for offline redo log backups with BRARCHIVE, or for
standby database backups.
• Ensure that the SBT_LIBRARY parameter in the initSAP_instance.sap file
points to the correct platform–specific Data Protector MML. For details on the Data
Protector MML location, see

Manual balancing

Manual balancing means that you manually group files into subsets, which are then
backed up in parallel. To group files into subsets, add the manual_balance section
to the Data Protector SAP R/3 configuration file as described in the following example.
Example
Suppose that we have a backup specification named SAP-R3 with the following files
to be backed up: fileA, fileB, fileC, fileD . To group the files into three
subsets (0={fileA, fileC}, 1={fileB}, 2={fileD}), add the following lines
to the Data Protector SAP R/3 configuration file:
manual_balance={
SAP-R3={
