Recovering the IDB
Chapter 9422
• If the IDB is installed on Microsoft Cluster Server, take the
OBVS_VELOCIS cluster group offline using the Cluster Administrator
utility on the active node before performing the guided autorecovery.
When the guided autorecovery has finished, bring the OBVS_VELOCIS
and OBVS_MCRS cluster groups online using the Cluster
Administrator utility.
Recovery
Procedure
To recover the IDB, run the omnidbrestore -autorecover command.
The command reads the IDB recovery file and if IDB backups are logged
to the file, it stops the services and starts restore of the IDB back in
place. All the options are generated automatically using data from the
IDB recovery file.
Once the restore is complete, the omnidbrestore checks if transaction
logs are available to be replayed. If logs are available, you are asked to
confirm the replay of the logs. If this step is cancelled or transaction logs
are not available, output describes how to update the IDB since the last
IDB backup by:
• importing media
• finding the transaction logs and replaying them later
Once you replay logs or import media to update the IDB, the full IDB
should be successfully recovered.
Handling Minor Database Corruption in the DCBF
Part
If you detect that the IDB corruption is of minor severity, it means that
some DC binary files are missing or corrupted. If this is the case, there is
no need for complete IDB recovery. You can easily recreate the binary
files by importing catalog from media. Choose the recovery procedure
depending on the corruption type.
Recovering if DC
Binary Files Are
Missing
DC binary files are organized so that one binary file exists for each
medium. If some DC binary files are missing, media positions of some
media point to the non-existent files. An error message is displayed when
browsing the relevant filesystems. Proceed as follows:
1. From the omnidbcheck -bf output, identify the Medium ID of the
missing binary file. Run the omnimm -media_info <Medium>
command to get other attributes of the medium, such as medium
