Use the PROBKUP utility with the online and enableai qualifiers to enable after-imaging on an online database. The completed backup is the baseline for rolling forward after-image extents.

To enable after-image for an online database:

  1. Create the AI areas in your database. See Create after-image areas for detailed instructions.
  2. Simultaneously backup your database online and enable after-imaging with PROBKUP.

    Use the command shown:

    probkup online dbname output-device enableai

    For complete PROBKUP syntax information, see PROBKUP utility.
