Verifying takeover by a standby controller
To verify that a standby controller can take over the functions of the controller, perform these actions:
- Stop the controller.
- Unless automatic takeover was not specified in the Tivoli Workload Scheduler for z/OS runtime
options, order the standby controller to take over the functions of
the controller, using this command:
MODIFY ssname,TAKEOVER
See the XCFOPTS statement in the Tivoli Workload Scheduler for z/OS Customization and Tuning guide to learn how to set up automatic takeover as a runtime option. - Check that this message appears in the message log:
Standby controller message
EQQZ129I TAKEOVER IN PROGRESS
When the standby controller has taken over the functions of the controller, more messages will appear in the message log. These are the same messages that appear when a controller is started. Verify that the takeover was successful by following the procedures used in the verification of the controller.
