Use the following procedure to enable after-imaging on your source database:

  1. Create a new structure file—named, for example, source-db-name_ai.st—and edit it to add after-imaging.

    The following is sample of the structure file:

    # addai.st
a C:\OpenEdge\WRK\ f 1024
a C:\OpenEdge\WRK\ f 2048

    Be sure to give the new structure file a different name from the one you created in Step 1: Create a structure file.

  2. Apply source-db-name_ai.st to the source database.

    The syntax is shown:

    prostrct add source-db-namesource-db-name_ai.st
  3. Back up the database.

    The syntax is shown:

    probkup source-db-name source-db-backup-name
  4. Begin after-imaging.

    The syntax is shown:

    rfutil source-db-name -C aimage begin
