Tuning OPP Heap Memory Issue

SELECT service_id, service_handle, developer_parameters
FROM fnd_cp_services WHERE service_id = (SELECT manager_type
FROM fnd_concurrent_queues
WHERE concurrent_queue_name = 'FNDCPOPP');

use the below command to check whether you will succeed with 2GB of heapsize or not.

$ java -Xmx2048m -version

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

Increase the memory value from 512 to 1024 or higher

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');
