Oracle Scheduler Locking Tasks Causing Performance Issues
Last updated on NOVEMBER 14, 2017
Applies to:Oracle Scheduler - Version 12.1.3 and later
Information in this document applies to any platform.
Scheduler locking Tasks for more time, which is causing Performance issues.
Since upgrading to 12.1.3 the optimizer run cycles have more than doubled, and more importantly, it is locking records that it should not.
This locking issue was fixed in 12.1.2, but this fix does not seem to have been included in 12.1.3.
This is happening frequently since upgrade, locking Mobile updates for as long as 10 minutes in some cases.
