I've recently installed OEM 12c R4 and set the values for OMS_HEAP_MIN (-Xms) and OMS_HEAP_MAX (-Xmx) to 1740M in a 64-bit environment as per Oracle recommendation. This can be found at http://docs.oracle.com/cd/E24628_01/install.121/e24089/sizing.htm
But with only 1740M heap size, i am frequently getting java heap size related alerts.
Is there any specific reason for recommending only 1740M?
Can I safely increase the heap size to 4G as the manual suggest for Medium size OEM installations in case of other Java vendors
