After configuring Coherence Cache for WebCenter Portal Content Presenter customer was not able to see the Coherence MBeans in the Enterprise Manager to verify the installation. Further investigation shown that this was due to WebLogic Server configuration. When starting the WebCenter Portal managed server following message was noticed in the logs:
<Warning> <Management> <BEA-141277> <The JMX MBean PlatformMBeanServerUsed attribute is true, but the Platform MBeanServer was created without the hooks for the WLS security infrastructure. The Platform MBeanServer will NOT be used and Platform MBeans will NOT be available via the WLS Runtime or Domain Runtime MBeanServers. This can occur if you have defined Platform MBeanServer system properties or JVM options (-Dcom.sun.management.jmxremote or JRockit -XManagement).
To allow the Platform MBeanServer to be used, you must either remove the system properties/JVM options or start WLS with the following system property:
If you want to eliminate this log error and do not need Platform MBeans to be available via WLS, then set the PlatformMBeanUsed attribute in the JMXMBean to false.>
