Deadlocks

A deadlock is an unresolvable contention between multiple requestors for a resource. Resources are either DC/UCF system resources (such as programs and storage) or database resources (such as areas and records). CA IDMS/DB uses different control block structures to track contention for DC/UCF system resources and database resources. Although it tracks deadlocks using different control block structures, the same deadlock detection mechanism is used to resolve deadlocks.
