This topic explains how to configure VMware Tanzu GemFire RMI registry ports and RMI connectors.
Tanzu GemFire programmatically emulates out-of-the-box JMX provided by Java and creates a JMXServiceURL with RMI Registry and RMI Connector ports on all manageable members.
Configuring JMX Manager Port and Bind Addresses
You can configure a specific connection port and address when launching a process that will host the Tanzu GemFire JMX Manager. To do this, specify values for the jmx-manager-bind-address, which specifies the JMX manager’s IP address and jmx-manager-port, which defines the RMI connection port.
The default Tanzu GemFire JMX Manager RMI port is 1099. You may need to modify this default if 1099 is reserved for other uses.
Using Out-of-the-Box RMI Connectors
If you need to use standard JMX RMI in your deployment for other monitoring purposes, set the Tanzu GemFire property jmx-manager-port to 0 on any members where you want to use standard JMX RMI.
If you use out-of-the-box JMX RMI instead of starting an embedded Tanzu GemFire JMX Manager, you should consider setting -Dsun.rmi.dgc.server.gcInterval=Long.MAX_VALUE-1 when starting the JVM for customer applications and client processes. Every Tanzu GemFire process internally sets this setting before creating and starting the JMX RMI connector in order to prevent full garbage collection from pausing processes.
