Setting the Archive Mode

By default the management server database runs in no-archive mode, which requires you to backup the database manually by using a cold RMAN backup. A cold RMAN backup is an RMAN backup without the management server running. If you want to take an RMAN hot backup of the database, switch the database to archive mode. An RMAN hot backup is with the database running while the backup is occurring.

Keep in mind the following implications if you decide to leave the database in no archive mode.

•If you leave the database in no archive mode (Disable Database Archive Mode and RMAN Backup), it is up to you to back up the management server manually. If you forget to back up your management server and your management server fails, you will not have a database to import. To learn more about manual backups, see ”Running a Cold Backup” on page 213. Export the database after you change the database mode to no archive. See ”Exporting the Database” on page 208.

•Scheduled RMAN backup jobs do not run. If you change the database mode to no archive during an RMAN backup, the RMAN backup will error out.

•If the database fails as a result of a corrupt data file, the database can only be restored to the last export backup available. This requires recreating the database along with the import.

To change the archive mode:

1.Access the Database Admin Utility as described in ”Accessing the Database Admin Utility” on page 206.

2.Click Archive Mode Switch in the left pane.

3.Select one of the following:

•Enable Database Archive Mode and RMAN Backup - Select this option if you plan to run database in archive mode and automated backup while the management server is running. If database is already in archive mode, you can use this option to clean up archive files. See ”About the Database Admin Utility” on page 206 for more information about the automatic backups. When you change the database to archive mode, you reset the logs SCN, set the archive parameter in the database parameter file and enable the RMAN backup scheduler. Take a current RMAN backup after switching to archive mode (Options > Storage Essentials > Manage Product Health > Disk Space > RMAN Backup > Backup Now in HP Systems Insight Manager) as described in ”Performing an RMAN Hot Backup” on page 204.

•Disable Database Archive Mode and RMAN Backup - Select this option if and only if you always shut down the management server prior to a backup. With database running in no-archive mode, you can only cold back up your database. When you change the database to no archive mode, you reset the logs SCN, set the archive parameter in the database parameter file and disable the RMAN backup scheduler. See ”Running a Cold Backup” on page 213 for more information. Export the database after switching to no archive mode. See ”Exporting the Database” on page 208.
