In some environments JVMs have transient identity, such as when a single script spawns multiple JVMs.
For example, an environment may consist of WebSphere on IBM Mainframes, using a dynamic workload management feature that spawns new JVMs for an existing application server (called a servant). These JVMs are exact clones of an existing JVM, but each of them has a different process ID. Based on load, any number of additional JVMs may be created.
To name nodes automatically
The App Server Agent can automatically name the dynamically generated JVMs using the appdynamics.agent.reuse.nodeName property. See Reuse Node Name Property to enable re-use of node names and Auto Node Name Prefix Property to set the prefix used for automatically-named nodes. You specify these properties in your startup script, using the following format:
-Dappdynamics.agent.reuse.nodeName=true -Dappdynamics.agent.reuse.nodeName.prefix=<node name prefix>
The name of a node is available for reuse if the node has been out of contact with the Controller for a period of time that exceeds the node retention setting. For more about historical nodes, node retention and deletion, see Remove Unused Nodes.
