For the first phase of incremental restore with Analytics Database 16.20 Update 2, the following limitations and restrictions apply:

  • DBC only jobs are not supported.
  • The incremental restore job must be created from an incremental restore enabled backup job.
  • The next incremental restore option can only process one save set at at a time. You select the backup to start from and run the job repeatedly till you get to the save set you want restored.
  • You cannot stop this command: build_restore_objects.
  • You can stop these commands only through cnsterm 6:
    • To stop cleanup_ir_source_system, run this command from the source database:

      start bardsmain -a|abort c|cleanup

    • To stop reset_ir_target_system, run this command from the target database:

      start bardsmain -a|abort r|reset

  • SQLE 17.00.09.01 and later versions support online incremental restore.
  • You cannot restart an incremental restore job.
  • Enhanced locking management is not supported with IR.
  • IR does not work with a down AMP.
  • LOGGING INCREMENTAL ARCHIVE is not retried indefinitely.
