Figure 13–1 illustrates how the queue manager works to manage queue activity
in an OpenVMS Cluster environment.

Job Controller
When a user submits a batch or print job to a queue, the queue manager performs
the following tasks:
1. Receives the user’s queue request, including information about the type of
job, the file name or names, the name of the queue, and any special options.
2. Stores and retrieves appropriate information from the queue database to
print or execute the job.
3. Places the job in the appropriate queue to await its turn for processing:
a. Print jobs are sent to an independent process, called a symbiont, for
formatting and are then sent to the printer for printing.
b. For batch jobs, the job controller creates a batch job process.
