You can use WLST commands to start, stop, and monitor a server instance without connecting to an Administration Server. WLST commands and scripts-WLST offline serves as a Node Manager command-line interface that can run in the absence of a running Administration Server. For more information about JMX, see Developing Custom Management Utilities With JMX for Oracle WebLogic Server. You access either version of Node Manager-the Java version or the script-based (SSH) version-from the following clients: (In addition, an SSH client in the form of a shell command template is provided for use with the script-based Node Manager.)Īdministration Console, from the Environments > Machines > Configuration > Node Manager page.įor example, you can create JMX utilities that communicate with the Administration Server and perform operations on the ServerLifeCycleRuntimeMBean which in turn uses Node Manager internally to perform operations. inetd allows Node Manager to be automatically restarted upon receiving a request on the configured port.Ī Node Manager client can be local or remote to the Node Managers with which it communicates. The Java version of Node Manager can be used in conjunction with inetd on supported UNIX systems. The script version of Node Manager also requires a smaller footprint than the Java version. RSH and SSH are generally easier to configure than SSL which is the security method used by the Java version of Node Manager. The script-based Node Manager requires a much simpler security configuration than the Java version. In order to use consensus leasing, you may see faster performance when using the Java version of Node Manager. The scripted version of Node Manager is not supported on Windows. If you are installing WebLogic Server on a Windows system, you must use the Java version of Node Manager. The following considerations can help you decide which version is ideal for your environment: Which version of Node Manager to use depends on the requirements of your WebLogic Server environment.
