archive_function

This parameter defines the type of backing up  with BRARCHIVE.

Syntax: 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: Back up the offline redo log files.

·        second_copy: Create a second copy of offline redo log files that were already backed up.

·        delete_saved: Delete offline redo log files that were backed up once.

·        delete_copied: Delete offline redo log files that were copied a second time.

·        save_delete: Back up the offline redo log files and then delete these files.

·        second_copy_delete: Create a second copy of offline redo log files that were already backed up and then delete these files.

·        double_save: Back up the offline redo log files on two backup devices (tape devices) in parallel.

·        double_save_delete: Back up the offline redo log files on two backup devices (tape devices) in parallel and then delete the files.

·        copy_save: Create 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: Create a second copy of offline redo log files that were already backed up. These are then deleted. 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, the second possibility is not of great interest and should only be used with the corresponding BRARCHIVE command option call if it must be used at all.
