如何处理不能正常开启 workflow mailer service 问题

Applies to: 
Oracle Workflow Cartridge - Version: 11.5.10.0 to 12.0.6 - Release: 11.5 to 12
Information in this document applies to any platform.

Symptoms
When trying to start the Workflow Notification Mailer, the following error occurs:

 

Error:
The service container is not running.
Additional information:

1) Workflow Mailer Service is down (Actual: 0, Target: 1), and when trying to start it, it remains down.

2) Workflow Agent Listener Service is up and all the corresponding listeners (workflow deferred agent listener, workflow java deferred agent

listener...) are up and running.

3) Debug service log (DebugSvcXXXXXX.txt) shows the following error:

 

[Unloading class sun.reflect.GeneratedSerializationConstructorAccessor80]
376700K->376655K(380160K), 0.6887140 secs]
Exception in thread "Cache Stats Writer" java.lang.OutOfMemoryError: Java heap
space
Cause
The memory allocated to mailer service is 384 MB which is too low.

This value can be seen in FNDSM log. When ICM diag is enabled, FNDSM log shows the command used to start mailer service:

AQCART: /u01/TEST/12.0.4/inst/apps/TEST_fin/admin/scripts/java.sh -server

-Xmx384m entry refers to the memory allocated to workflow mailer service.

Solution
Increase the memory allocated to mailer service by following the steps from Document 444939.1 How do you Change the Maximum Memory Size taken by

In a first step, set it to 512 MB and retest.
