Does Job Scheduler expose a management interface?
Job Scheduler does expose a management interface that can be access through JMX MBeans. Two kinds of MBeans are published: SchedulerMBean
and JobMBean
. The former is used to manage a Job Scheduler instance and the later a specific job instance. These MBeans are accessible from the OC4J Administration Console.
Can I enable and disable MBean publication?
Yes. If the <env-entry>
value of oracle.ias.scheduler.jmx
is set to true, then MBean publication is enabled; otherwise, the beans are not published.
What privileges are required to access the Job, Job Scheduler, and Job Scheduler Aggregation MBeans?
Access to the Job and Job Scheduler MBeans requires the same privileges as those of the user application in which they are defined. Access to the Job Scheduler Aggregation MBean requires OC4J administrator privileges.
