DBMS_JOB and Oracle Scheduler share the same job coordinator and job slaves, and they are both controlled by the JOB_QUEUE_PROCESSES parameter. The actual number of job slaves created for Oracle Scheduler jobs is auto-tuned by the Scheduler depending on several factors, including available resources, Resource Manager settings, and currently running jobs.

We have 2 production environments say XX and XY. Both are on Oracle 11g Release 11.2.0.2.0. Both the environments have a queue table and a job queue to en-queue/de-queue jobs and process them.

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. Answer: The job_queue_processes is the number of concurrent jobs running, which your DBA should know from their daily job stream. The easy way to set job_queue_processes is to set it to a reasonable value such as five, since only very busy batch system will have n=more than five … If you have job queue_processes = 1, then one at a time will run.
