How to resolve Java Heap Space error in Output Post Processor?




Solution 1
==========




1. Determine what the heap size per OPP process is currently:
select DEVELOPER_PARAMETERS from FND_CP_SERVICES
where SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUES
where CONCURRENT_QUEUE_NAME = ‘FNDCPOPP’);


2. The default should be:
J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx512m


3. Increase the Heap Space per Process to 1024:
update FND_CP_SERVICES
set DEVELOPER_PARAMETERS =
‘J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx1024m’
where SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUES
where CONCURRENT_QUEUE_NAME = ‘FNDCPOPP’);


4. Bring the managers down.
5. Please run the Concurrent Manager Recovery feature to address any Concurrent Manager / Concurrent Processing issues within the Oracle Application Manager.  NOTE: Regular use of the CP Analyzer in Note 1411723.1 can provide an Immediate Analysis and Output of a Concurrent Environment.
6. Bring the managers up again.

Configure the XML Publisher Administrator Configuration settings.
1. As XML Publisher Administrator navigate to Administration->Configuration.
2. Under Temporary Directory pick a temporary file location on your concurrent processing node. This should be at least 5GB or 20x larger than largest XML data file you generate
3.  Under FO Processing, set:
o Use XML Publisher’s XSLT processor set to True
o Enable scalable feature of XSLT processor set to False
o Enable XSLT runtime optimization set to True
