<h1 class="topictitle1">Job queue entries</h1>
<div><p>Job queue entries in a subsystem description specify from which
job queues a subsystem is to receive jobs. When the subsystem is started,
the subsystem tries to allocate each job queue defined in the subsystem job
queue entries. </p>
<p>For example, a job queue entry in the subsystem description QSYS/QBASE
specifies that jobs can be started using the job queue QGPL/QBATCH. Jobs can
be placed on a job queue even if the subsystem has not been started. When
the subsystem QBASE is started, it processes the jobs on the
queue. A subsystem description can specify the maximum number of jobs (batch
or interactive) that can be processed at the same time. The number of jobs
that can be active from any job queue is specified in the job queue entry.</p>
