Managing the Data Protector Internal Database

 

 

Recovering the IDB

 

 

the procedure below, bring the OBVS_VELOCIS and OBVS_MCRS

 

 

cluster groups online using the Cluster Administrator utility.

How to Replay

Proceed as follows:

Transaction Logs

1.

Run the following command to replay the transaction logs:

 

 

 

omnidbrestore -replay_only -firstlog

 

 

<FirstTransactionLog>

 

 

where <first_trans_log> is the first transaction log that was

 

 

created just after the IDB backup was started.

 

 

At the end of the omnidbrestore -autorecoveroutput, Data

 

 

Protector displays the exact command you should use to replay the

 

 

transaction logs, giving you the name of the first transaction log.

 

 

For example, the command could be:

 

 

omnidbrestore -replay_only -firstlog AAAAAC

 

 

where AAAAAC is the first transaction log created after the IDB

 

 

backup was started.

 

2.

Run the omnidbcheck command.

 

This completes the recovery procedure.

 

Recovering the IDB to a Different Disk Layout

 

You can restore the IDB to a disk of a different size than before the

 

disaster, and to different directories than at the backup time.

Prerequisites

Ensure the following before recovering the IDB to a different disk layout:

 

If possible, store the media.log file from the previous installation to

 

 

a safe place. It will provide you with information about the media

 

 

used since the last IDB backup.

 

Verify that Data Protector is installed on the Cell Manager and the

 

 

system where a device is attached. (Preferably, this device was used

 

 

for the IDB backup.)

 

Import the media with the IDB backup.

Recovery

After you meet the prerequisites, proceed as follows to recover the IDB:
