Configuring the Scheduler › Configure the Scheduler Heartbeat Interval

Configure the Scheduler Heartbeat Interval

The primary, shadow, and tie-breaker schedulers update the database with their heartbeats at regular intervals. If a scheduler does not update the database after two intervals, that scheduler is deemed unavailable and the system either fails over to the available scheduler or leaves high availability mode. You can configure the length of each interval.

Notes:

• The default value is 15 seconds.
• If CA Workload Automation AE runs in high availability mode with dual event servers, the specified HA Poll Interval value doubles. The increased interval provides enough time for both databases to be updated before the schedulers poll for one another's status. For example, when you set the interval to 15 seconds, the schedulers refresh their status every 15 seconds in single event server mode and every 30 seconds in dual event server mode.
• On UNIX, the equivalent configuration parameter is HAPollInterval.

Follow these steps:

1. Click Start, Programs, CA, Workload Automation AE, Administrator.

   The Services - CA Workload Automation AE Administrator window appears, displaying a list of services installed on the selected instance.

4. Right-click the scheduler and select Stop.

   The scheduler stops.

5. Click the Scheduler icon on the toolbar.

   The Scheduler - CA Workload Automation AE Administrator window appears. The Controls tab is selected by default.

6. Enter the interval (in seconds) between status polls in the HA Poll Interval field, and click Apply.
7. Click the Services icon on the toolbar.

   The Services - CA Workload Automation AE Administrator window appears, displaying a list of services installed on the selected instance.
