Default value: save

Possible values:

  • save: backs up the offline redo log files

  • second_copy: creates a second copy of offline redo log files that were already backed up

  • delete_saved: deletes offline redo log files that were backed up once

  • delete_copied: deletes offline redo log files that were copied a second time

  • save_delete: backs up the offline redo log files and then deletes these files

  • second_copy_delete: creates a second copy of offline redo log files that were already backed up and then deletes these files

  • double_save: backs up the offline redo log files on two backup devices (tape devices) in parallel

  • double_save_delete: backs up the offline redo log files on two backup devices (tape devices) in parallel and then deletes the files

  • copy_save: creates a second copy of offline redo log files that were already backed up and then back up the offline redo log files that have been created in the meantime

  • copy_delete_save: creates a second copy of offline redo log files that were already backed up and then deletes these files. The offline redo log files that have been created in the meantime are backed up.

If there is only one tape device, you can use parameter archive_function = copy_save or copy_delete_save to ensure that BRARCHIVE creates a second copy of the offline redo log files in one run, deletes it if necessary and continues backing up immediately. This can also be done by first calling BRARCHIVE with archive_function = save and then with archive_function = second_copy or second_copy_delete. However, two BRARCHIVE calls with modified parameters are necessary in this case. In practice, we recommend you to only use the second possibility with the corresponding BRARCHIVE command option call if at all.
