Generating Additional Deadlock Information
If you vary deadlock details ON, the deadlock detector provides additional information in the form of DC001001 messages during the processing of a deadlock. This information can prove useful in researching the cause of a deadlock situation because it identifies the programs and subschemas involved. However, it also increases the overhead of detecting deadlocks. In an active system in which waits for resources are common, it is recommended that the generation of deadlock details only be initiated when researching a specific deadlock situation.
