12.2 NEW FEATURE JOB_QUEUE_PROCESSES=4000 CAN ONLY HANDLE A MAXIMUM OF 1024 JOBS

(Doc ID 2315892.1)

Last updated on OCTOBER 17, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 12.2.0.1 and later
Information in this document applies to any platform.

Symptoms

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. 

Testcase:

Despite the fact that sufficient resources are available the number of maximum simultaneous jobs will not overcome a limitation of 1024.
