RRS warm start

An RRS warm start is also named recycling RRS. For an RRS warm start:
  1. Whenever doing a warm start of RRS, first shut down its exploiters whenever possible, as documented inz/OS MVS Programming: Resource Recovery. For example, WebSphere® does not handle RRS termination and terminates itself when it detects RRS is not available. Additional exploiters might encounter abends when RRS terminates if they had outstanding processing activity at that time. IMS™ can terminate for some abend conditions.
  2. Terminate RRS with one of the following commands:
    • SETRRS CANCEL, which terminates RRS with an abend code X'222'.
    • SETRRS SHUTDOWN, which first stops each resource manager and then terminates RRS without an abend (normal termination).
  3. Restart RRS with the Automatic Restart Manager (ARM) or by issuing the START RRS command.
