The following applies to warm and cold starts of the
Enterprise Server IMS Database Control feature.
- All database statuses are set to NOTOPEN when an enterprise server is first started and when a cold start is performed.
- When IMS Database Control is started via a warm restart, either by an automatic restart after the abnormal termination of Database Control or by a normal startup, database statuses are restored.
- If a warm start is the result of Database Control termination and the databases have been left in an ambiguous state, they are recovered by the Backward Recovery process.
- If a warm start is the result of Database Control termination and the databases are not recoverable, then they might be placed in a stopped state.
