Performing a Cross-Machine or Duplicate Restore from an Oracle Conflicting Backup

If the same backup piece name exists for two different Oracle instances, errors can occur in a cross-machine or duplicate restore.

• ORA-19626: backup set type is archived log - cannot be processed by this conversation

• ORA-19615: some files not found in backup set

• ORA-19613: datafile 3 not found in backup set

Procedure

• Include the CvSrcClientName environment variable for the source client name in the following RMAN restore script.

  allocate channel ch1 type 'sbt_tape'
  PARMS="SBT_LIBRARY=$[software install path]/Base/libobk.so,BLKSIZE=1048576,
  ENV=(CvClientName=$[clientname],CvInstanceName=$[instance_name],CvSrcClientName=$[sourceclientname])";
  

  CvClientName is required in a clustered environment. It is the virtual client name in the CommCell from where you are running the RMAN script.

  CvInstanceName is required in an environment with multiple Commvault instances.
