Answer: The job_queue_processes parameter specifies the maximum number of processes that can be created for the execution of jobs and the value for job_queue_processes. It specifies the number of job queue processes per instance.
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. DBMS_JOB and Oracle Scheduler share the same job coordinator and job slaves, and they are both controlled by the JOB_QUEUE_PROCESSES parameter.
コンテナには、 CDB$ROOT 、 PDB Thanks for your comments. We have reset the value of parameter job_queue_processes to 5 now. Its working fine now. I have one question, if the machine has 1 cpu and i set the parameter job_queue_processes=2 as you have suggested then what will be the effect if there are 3 jobs scheduled like this:- 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. 2016-03-08 · job_queue_processes.
If you have job queue processes = 2, then two will run at the same time, it will take about 45+ minutes -- 15plus minutes (for two) + 15plus minutes (for next two) + 15 minutes for one 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. … 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 2016-03-08 Question: Is there a way to automatically remove jobs from the job queue? Also, can I remove a job after it is finished executing?
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.
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). Replication uses job queues for data refreshes. Advanced queuing uses job queues for message propagation. You can create user job requests through the DBMS_JOB package.
2016-03-08 · job_queue_processes. See the Oracle Documentation – value specifies the maximum number of job slaves to be created to execute jobs started by either DBMS_JOBS or DBMS_SCHEDULER; 1000; Set it to a rough equivalent of 2 * CPU cores; In Oracle Database 12c we introduced the automatic stats gathering during CTAS and IAS (into an empty table only) operations.

This is one of the most common Scheduler questions asked. Here we list some of the common problems and their solutions. 1) job_queue_processes may be too low (this is the most common problem) The value of job_queue_processes limits the total number of dbms_scheduler and dbms_job jobs that can be running at a given time.
Answer: The job_queue_processes is the number of concurrent jobs running, which your DBA should know from their daily job stream.
Oracle says that at some point in the future, it is expected that dbms_job will
1、job_queue_processes参数 alter system set job_queue_processes= 0,1000 下面是11g reference的描述： 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. 最近在一个oracle11g数据库里面新建了一个job，job不会在设定的时间执行。但是手动执行是可以的。后来网上找到是因为job_queue_processes的参数设置问题：1. job_queue_processes取值范围为0到10002. As another example, assume that the parameter job_queue_processes is set to 32, and you issued a dbms_stats.gather_schema_stats on the SH schema.

DBMS_JOB and Oracle Scheduler share the same job coordinator and job slaves, and they are both controlled by the JOB_QUEUE_PROCESSES parameter. Setting job_queue_processes=4000 should allow a maximum of 4000 jobs to be executed simultaneously as long as OS resources allow this to happen. However, on a system with sufficient resources the maximum number of simultaneous jobs that we can run is 1024.
