Use the RFUTIL utility with the AIMAGE BEGIN qualifier to enable after-imaging. The use of after-imaging requires a recent backup of the database because the database backup and AI files are treated as a recoverable set of files.

To enable after-imaging for an offline database:

  1. Create the AI areas in your database. See Create after-image areas for detailed instructions.
  2. Back up your database.
  3. After you back up your database, enable after imaging.

    Use the following command to enable after-imaging:

    rfutil db-name -C aimage begin

After imaging is enabled. However if the database has been modified since it was last backed up, RFUTIL displays an error message and does not enable after-imaging.
