Oracle Configurator performs poorly (Java: Out of memory)
When using the Oracle Configurator observing strange behaviour of the oacore java process.
Customer has defined 5 oacore java processes in the OC4J container with a max heap space of 2GB (the jdk is 32-bit).
The load increases when the Java process consumes 100% CPU and is finally killed by opmn.
In the oacorestd.err is seen: java.lang.OutOfMemoryError: GC overhead limit exceeded
Tried adding the paramter -XX:-UseGCOverheadLimit to startup, and paramter
-XX:-UseGCOverheadLimit , Both didnt help
The CPU still shows at100%
(Five oacore JVMs, 1 forms JVM and one oafm JVM (was earlier onlyl 2 oacore
JVM's). 24 cores.
and EBS users Average 45.84 Max 108
Concurrent Requests Average 47.31 Max 140
MaxPermSize is set to 512MB
