Recommendations when you configure an Oracle Copilot with universal shares

Note the following recommendations when you configure an Oracle Copilot with universal shares:

  • Ensure that there is at least one datafile on one share or backup may fail with an empty share error.

  • Ensure the following:

    • Multiple shares are mounted with the correct NFS options on the Oracle server.

      See About policy attributes.

    • Multiple mount paths are added into the selection list of an Oracle Copilot policy.

  • Ensure that the backup datafile stream number is larger than number of shares in the Oracle Copilot policy.

    If the number of streams are less, NetBackup automatically changes the number of parallel streams to match the shares.

  • If the source Oracle is of the type RAC, ensure that multiple shares are mounted on each instance node with the same mount path.

    For example, if there are four shares on four nodes, each node must have all shares mounted.

  • If you want to replace an old share, ensure that the new share is mounted on the same path. Run RMAN crosscheck before you start any backup job.

  • If you want to add a new share to the policy, ensure that the new share is mounted on all Oracle nodes.

    If you have new datafiles added to the database, the datafiles are backed up to the new share. If there is no new datafile added, the new share is empty and the backup job partially succeeds. It is recommended that you create a new policy for all the shares including the new share.

  • You can restore datafile copies on the new mount shares from multiple nodes of Oracle RAC. It helps to improve the restore performance. To improve the performance, start by configuring multiple instances in RMAN script.
