This parameter defines the type of BRARCHIVE backup.
archive_function = save|second_copy|delete_saved| deleted_copied|save_delete|second_copy_delete| double_save|double_save_delete|copy_save|copy_delete_save
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.
