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.

      Refer to the NetBackup for Oracle Administrator's Guide for more information about NFS options.

    • 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 trigger 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. Add the new mount path into the policy. Run a full backup with the Force Rescan option.

  • 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.
