title: Altering JOB_QUEUE_PROCESSES
body: <p>Does altering the JOB_QUEUE_PROCESSES to 0 on an Oracle DB block the Oracle jobs from being scheduled too?  </p>
  
  <p>I found in <a href="http://download-west.oracle.com/docs/cd/A97630_01/server.920/a96521/jobq.htm" rel="nofollow noreferrer">http://download-west.oracle.com/docs/cd/A97630_01/server.920/a96521/jobq.htm</a> some information about it, principally, the following: </p>
  
  <blockquote>
    <p>The JOB_QUEUE_PROCESSES initialization
    parameter controls whether a
    coordinator job queue process is
    started by an instance. If this
    parameter is set to 0, no coordinator
    job queue process is started at
    database startup, and consequently no
    job queue jobs are executed. The
    JOB_QUEUE_PROCESSES initialization
    parameter also specifies the maximum
    number of Jnnn processes that can
    concurrently run on an instance. The
    maximum number of processes that can
    be specified is 1000.</p>
  </blockquote>
  
  <p>However, I am uncertain what the "coordinator job queue" represents in the grand scheme of things. </p>
  
  <p>Thank you very much in advance for your timely responses.</p>
