Starting and stopping the Usage Monitor

Before you begin

A Usage Monitor job HZACUMON is provided with an embedded PROC named HZACJMON. If you want to start HZACJMON as a started task, copy from the embedded PROC from the hzac.HZACCONT.CNTL to an authorized PROCLIB.

Procedure

Procedure

  1. To start the Usage Monitor in normal mode, enter the following command:
    S HZACJMON
  2. To fully stop the Usage Monitor, enter one of the following commands:
    P HZACJMON

    F HZACJMON, STOP F

    HZACJMON,END

    These commands cause the Usage Monitor to stop data collection, attach a writer task to process the existing data in the collection repository, wait for the writer task to output the data, and then terminate.p

  3. To perform an immediate termination, enter the following command:
    F HZACJMON,CAN

    This command causes the server address space to stop data collection, detaches any running writer task which renders the output data in the data set unusable, deletes the current collection repository without writing out its contents, and terminates. If you use the z/OS system command CANCEL to stop the Usage Monitor, its collection repository remains in storage. To clear the collection repository from storage, you must restart the Usage Monitor.
