Optimizing JVM settings
PORT_MEM_ARGS , in the setSOADomainEnv.sh(.cmd) script, controls most
JVM related configuration settings. The following JVM settings for JRockit are
proven to be good in most environments:
PORT_MEM_ARGS="-Xms1536m -Xmx1536m -Xgcprio:throughput -XX:+HeapDumpOnOutOfMemoryError -XXtlasize:min=16k,preferred=128k,wasteLimit=8k"
We will describe each of these arguments in detail.
