DCMT VARY QUEUE Usage

Varying a Queue Online or Offline

A queue is initially defined as online or offline at system generation time by the ENABLED/DISABLED parameter of the QUEUE statement. The following considerations apply:

• When a disabled queue that has exceeded its threshold is varied ONLINE, the task associated with the queue is invoked at the next request to place a record in the queue.
• Varying a queue OFFLINE prevents the task associated with the queue from being invoked to process queue records. However, records can still be written to the queue until the maximum entry count is reached.
