Enabling Multiple Oracle Backup Copies Using RMAN

Create multiple copies of the data or log backups by using the RMAN commands. During a restores operation, if one of the copies is missing or corrupted, the restore operation automatically performs a failover to the other copy and can then restore the data.

Procedure

1. Edit the Oracle pfile or SP file and set the BACKUP_TAPE_IO_SLAVES initial parameter to TRUE.

2. Configure device type. On the RMAN command line, type the following command.

   Example

   RMAN> CONFIGURE DEVICE TYPE 'SBT_TAPE' PARALLELISM $[2] BACKUP TYPE TO BACKUPSET;
   

3. Specify two copies of data. On the RMAN command line, type the following command.

   Example

   RMAN> CONFIGURE $[DATAFILE] BACKUP COPIES FOR DEVICE TYPE 'SBT_TAPE' TO $[2];
   

4. Specify two copies of log backups. On the RMAN command line, type the following command.

   Example

   RMAN> CONFIGURE $[ARCHIVELOG] BACKUP COPIES FOR DEVICE TYPE 'SBT_TAPE' TO $[2];
   

5. Add the environmental variables for the client and instance where the Oracle instance is installed. On the RMAN command line, type the following command.

   Example

    
   configure channel $[ch1] type 'sbt_tape' 
    PARMS="$[software_installation_path/Base/libobk.so],
    ENV=(CvClientName=$[client_name],
    CvInstanceName=$[instance_name])"

What to Do Next

• Perform backup operations from the CommCell Console.
