Enabling JMX for remote monitoring of Oracle ATG instances running behind a firewall causes the Publishing or BCC server to fail to connect to the instances due to firewall connection problems.

The Publishing server connects to the remote instances over a random port that is determined at JVM startup instead of using the RMI port configured by the Oracle ATG server instance (in the rmiPort property of the /atg/dynamo/Configuration component).

This document deals only with RMI connectivity problems when JMX is enabled in the JVM. Other types of RMI connectivity issues are described in <Document 1447769.1>.



JMX monitoring is enabled via the com.sun.management.jmxremote or com.sun.management.jmxremote.port JVM arguments. JMX is documented in detail in "Monitoring and Management Using JMX Technology":
