JOB_QUEUE_PROCESSES determine the maximum number of concurrently running jobs. In Oracle HTML DB release 2.0, transactional support and SQL scripts require jobs. If JOB_QUEUE_PROCESSES is not enabled and working properly, you cannot successfully execute a script.
JOB_QUEUE_PROCESSES specifies the maximum number of processes that can be created for the execution of jobs. It specifies the number of job queue processes per instance (J000, ... J999).
