When you enable configuration archive in your Oracle WebLogic Server domain, the entire domain configuration is backed up at every server restart. This is pretty much a must-have setting for every domain. There are absolutely no disadvantages in enabling this, and can come in extremely handy if you experience an issue and want to easily recover/rollback.

  1. Login to the Oracle WebLogic Server Administration Console.
  2. Click on the domain name on the left.
  3. Click on Advanced.
  4. Enable the 'Configuration Archive Enabled' option.
  5. Set the 'Archive Configuration Count'.
  6. Save and activate changes.
  7. Restart your entire domain.

The backup is saved to config-booted.jar under the $DOMAIN_HOME folder as shown:

Each archive is about 1 MB in size. Previous archives are stored in the ~configArchive folder.
