Setting up the monitor

The monitor does not require any special setup. It is started automatically when JES2 is started and shuts down when JES2 terminates normally. There are no initialization statements, PARMLIB or PROCLIB statements that need to be updated. However, you may want to define the address space to your security product. The monitor does not access any RACF®–protected resources; however, JES2 builds an ACEE based on attributes in the STARTED class. You should also ensure that it is classified to WLM consistent with your JES2 classification.

You cannot turn the monitor off. If the address space terminates because of error or operator command, the JES2 address space will restart the monitor. The overhead associated with the address space is minimal (less than 1% of a CPU). Repeated failures and restarts of the monitor address space will not impact normal system operations.
