Specifies the JNDI name of the work manager, which is used to manage
the number of tasks that can run concurrently with the scheduler. The work
manager also can limit the amount of Java EE context applied to the task.
The work manager is a server object that serves as a logical thread pool
for the scheduler. Each repeating task that is created using this scheduler
uses the Number of alarm threads specified in the work manager, which
affects the number of tasks that can run concurrently. Use the work manager Service
Names property to limit the amount of context information that is propagated
to the task when it runs.
When a task runs, the task is run in the work manager associated with the
scheduler instance. You can control the number of actively running tasks at
a given time by configuring schedulers with a specific work manager. The number
of tasks that can run concurrently is governed by the Number of alarm threads parameter
on the work manager.
Note: When you configure a scheduler resource on a Version 5.x
node or server, the scheduler must reference a work manager in the same scope.
For example, a scheduler instance configured at the server1 scope must use
a work manager also configured at the server1 scope.
