Description
Resolution:
When EMS uses a database as a datastore or JAAS/JACI modules, JRE needs to be configured in tibemsd.conf. You can find out the garbage collector by adding the following option:
Configure jre_option = -XX:+PrintCommandLineFlags in tibemsd.conf.
When EMS (8.2 with JRE 1.7) is started, it prints:
-XX:InitialHeapSize=262838336 -XX:MaxHeapSize=4205413376 -XX:+PrintCommandLineFlags -XX:+ReduceSignalUsage -XX:+UseCompressedOops -XX:+UseParallelGC
It shows that the JVM uses a parallel garbage collector.
