If the disk runs out of space and no empty after-image extent is available (even if you are using variable extents), you must perform emergency maintenance; otherwise, the database is forced to shut down. To prevent the database engine from shutting down when it exhausts after-image disk space, you must start your database with the after-image stall (-aistall) startup parameter.
You must archive and manage after-image extents as part of standard after-image processing. For further information about archiving your after-image extents, see OpenEdge Data Management: Database Administration.
