HP Data Protector Operations Guide
Example:
Note:
C:\Program Files\OmniBack\bin>omnidbutil –purge_stop
This is useful command to stop a purge in case you need to run urgent Data Protector operations.
/opt/omni/sbin/omnidbutil –writedb [–mmdb /db_unload/mmdb] –cdb /db_unload/cdb
C:\Program Files\OmniBack\bin>omnidbutil –readdb [–mmdb Directory ] [–-cdb
Directory ] [–no_detail ] [–check_overs ]
C:\Program Files\OmniBack\bin>omnidbutil –writedb [–mmdb Directory ] [–cdb
Directory ] [–no_detail ]
Note:
The [–mmdb /db_unload/mmdb] option is only required when executing a writedb on the
Manager of Managers (MOM) server. If you have a Manager of Managers (MOM) you need no
–mmdb on a client cell server.
Excluding the
mmdb from maintenance on a standalone cell is not a best practice.
During the course of the
writedb, you will be prompted to copy the IDB message and dcbf files
as follows:
Note
:
Please make a copy of following Internal Database directories and then press
ENTER to return Internal Database to normal state:
"/var/opt/omni/server/db40/msg"
"/var/opt/omni/server/db40/dcbf"
For example, copy them as follows:
cp –r /var/opt/omni/server/db40/msg/* /db_unload/idb/msg
cp –r /var/opt/omni/server/db40/dcbf/* /db_unload/idb/dcbf
/opt/omni/sbin/omnidbinit –force
/opt/omni/sbin/omnidbutil –readdb [–mmdb /db_unload/mmdb] –cdb /db_unload/cdb
Caution: Do not use the
omnidbinit command without being directed to do so by HP Support.
After the
readdb has completed, you need to copy the msg and dcbf files back to their orginal
location:
For example, copy them as follows:
cp –r /db_unload/idb/msg/* /var/opt/omni/server/db40/msg/
cp –r /db_unload/idb/dcbf/* /var/opt/omni/server/db40/dcbf/
Note: Refer to the HP Data Protector IDB Purge Best Practices White Paper (4AA2-4988ENW) for
more details.
DCBF
For Data Protector 6.x, it is recommended that the dbcf directories have the following properties:
• Maximum usage in MB (–
maxsize) = 32768
• Maximum number of files in directory (–
maxfiles) = 10000
• Minimum free space in MB (–
spacelow) = 2048
Note: The sequence number, Allocation sequence (–
seq), is not important since the global option
DCDirAllocation will be set.
