Use the RESTART parameter

The optional RESTART parameter forces the subsystem to complete initialization by passing checks designed to prevent the start of a second address space.

About this task

The RESTART parameter requires the FORCE operand, as in this example:

START IBMCN,RST=’,RESTART=FORCE’

You can stop the subsystem by issuing the z/OS® STOP command, as in this example:

STOP IBMCN

Important:

Use the RESTART parameter only if the subsystem address space ends abnormally and subsequent attempts to start the subsystem result in the CNDL018I message; this message indicates that the subsystem is already active. Verify that the subsystem address space named in the CNDL018I message is not active before using the RESTART parameter. If the RESTART parameter is used when the subsystem is already active, results are unpredictable. You must restart the subsystem to pick up any maintenance that was installed.

The OMEGAMON® subsystem cannot be executed as a batch job; it must be invoked as a started task.
