job_queue_processes = 5 (5 for saying a value) job_queue_interval = 1 This means that 5 new processes are raised that wake up every minute to see if there are any JOBs to launch. – It is recommended to put the name of the JOB to be able to identify its monitoring and follow-up later.

job_queue_processes is as simple and basic as it sounds - it is simply YOU telling US how many jobs to allow to run at the SAME TIME. Nothing more, nothing less. …

all jobs disabled to run. To schedule a job you submit it to the job queue, using the Oracle supplied DBMS_JOBpackage, and specify the frequency at which the job is to be run. Additional functionality enables you to alter, disable, or delete a job that you previously submitted. Job queue (Jnnn)processes execute jobs in the job queue.

Both the environments have a queue table and a job queue to en-queue/de-queue jobs and process them. However, if the job_queue_processes parameter is 0, then the max_job_slave_processes attribute will act as the upper limit for the number of slave processes.

Each one takes 15 minutes to execute serially You have a 4 cpu machine and discover that if all ran at the same time, it takes 20 total minutes for all 5. job_queue_process Hi Tom,I have been asked to find out optimal value for job_queue_process parameter on Oracle 11g on specific hardware.The approach that we have taken is as follows:1. Set the parameter value to 1000 (max limit) and execute 1000 jobs concurrently. The job procedure will have an infinite l Oracle Database - Enterprise Edition - Version 9.2.0.1 and later: JOB_QUEUE_PROCESSES Parameter, its Significance and Recommended value JOB_QUEUE_PROCESSES Parameter, its Significance and Recommended value JOB_QUEUE_PROCESSES Parameter, its Significance and Recommended value (Doc ID 2118028.1) JOB_QUEUE_PROCESSES specifies the maximum number of job slaves per instance that can be created for the execution of DBMS_JOB jobs and Oracle Scheduler (DBMS_SCHEDULER) jobs.
