DataPump Job Can Abort Under Extremely Heavy Loads And High Degrees Of Parallelism (Doc ID 1906165.1)

Last updated on JULY 10, 2014

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.3 to 11.2.0.4 [Release 11.2]
Information in this document applies to any platform.

Symptoms

- Starting too many DataPump exports/imports at the same time (eventually from a shell script),  after some time, some random DP jobs start throwing errors:


- The issue is related to the amount of datapump processes/jobs started at the same time. A similar issue was addressed in <Bug:16362123>, but Patch 16362123 didn't fix the errors.

Changes

 Many DP jobs are running concurrently. Under extremely heavy loads, when a Data Pump job is starting up, timeouts would occur during the creation of worker processes.
