Ebs opp error solution 1. pai_parameters of OPP is a runtime param of concurrent manager OPP, and the option of concurrent program 'xdotmgen' is a runtime param of the concurrent program. they are different. and to this issue, it shoshould tune parameter _parameters of OPP. 1. determine what the heap size per OPP process is currently: select parameters _parameters from FND_CP_SERVICESwhere SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUESwhere CONCURRENT_QUEUE_NAME = 'fndcpopp '); 2. the default shoshould be: J: oracle. apps. fnd. cp. gsf. GSMServiceController:-mx 512m3. increase the Heap Space per Process to 1024: update FND_CP_SERVICESset parameters _parameters = 'J: oracle. apps. fnd. cp. gsf. GSMServiceController:-mx1024m' where SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUESwhere CONCURRENT_QUEUE_NAME = 'fndcpopp'); 4. bring the managers down.5. Run cmclean. SQL script from Note 134007.1-CMCLEAN. SQL Non-Destructive Script to Clean Concurrent Manager Tables.6. Bring the managers up again. OR2. XML Publisher Administration configuration navigation path: XML Publisher Administrator> Home> Administration> Configuration. 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 shoshould be at least 5 GB or 20x larger than largest XML data file you generate3. Under FO Processing, set: o Use XML Publisher's XSLT processor set to True o Enable scalable feature of XSLT processor set to Falseo Enable XSLT runtime optimization set to True
