RE: [cinjug-users] Displaying which JVM in a cluster.

["Arnett, Matt" <Matt.Arnett@xxxxxxxxxx>]

We added system properties (-Dserver.dns=myServer1 -Dserver.port=7001) to the java command line in the startup scripts for each app server and then access these through code:

String dns = System.getProperty(“server.dns”);

String port = System.getProperty(“server.port”);

There's a class called VMID - I've not used it that much but it may be helpeful - It's in the RMI package (I think)

Subject: [cinjug-users] Displaying which JVM in a cluster.

Hi all,

We've got a clustered environment of two physical machines, each with two JVMs. Mirroring and magic dust yields a total of four identical JVMs and application trees. Same URL, different ports, but that's hidden under the covers.

Occasionally we (the developers) find ourselves wanting to know which JVM is providing a particular instance of an app. Does anybody know of any way we can retrieve an ID, port designation, etc to let us know this information?

Thanx,
