Bereich	Beschreibung
Putty	Login as oracle on telde.local [oracle@telde ~]$ cd middleware/user_projects/domains/base_domain/ [oracle@telde base_domain]$ vi startWebLogic.sh
Putty/vi	Add the following java Options before starting the WLS instance: JAVA_OPTIONS="-Xmanagement:ssl=false,authenticate=false,port=7091" export JAVA_OPTIONS ${DOMAIN_HOME}/bin/startWebLogic.sh $* Save file and Close vi.
Putty	Start WLS [oracle@telde base_domain]$ ./startWebLogic.sh …. Notice the starting of the management server … [JRockit] Management server started on port 7091, ssl=false, authenticate=false. …
Client	Start JRockit Mission Control
JRMC	Create a new connection Enter Host Enter Port Click: Test connection => Status keeps “Unable to connect” Click: Finish Starting the console on the newly created connection you might receive the following exception: Could not open Management Console for telde.local.   com.jrockit.mc.rjmx.ConnectionException: Connection refused to host: 127.0.0.1; nested exception is:     java.net.ConnectException: Connection refused: connect     com.jrockit.mc.rjmx.ConnectionException: Connection refused to host: 127.0.0.1; nested exception is:         java.net.ConnectException: Connection refused: connect         at com.jrockit.mc.rjmx.ConnectionManager.connect(ConnectionManager.java:63)         at com.jrockit.mc.console.ui.actions.StartConsole$1.preConnect… So how to fix?
Putty	Stop WLS
	Edit startWebLogic.sh Add -Djava.rmi.server.hostname=<remotehost> to the java options so that it looks like
Putty/vi	.. JAVA_OPTIONS="-Djava.rmi.server.hostname=telde.local -Xmanagement:ssl=false,authenticate=false,port=7091" export JAVA_OPTIONS ${DOMAIN_HOME}/bin/startWebLogic.sh $* Save file and exit vi.
Putty	Start WLS once again [oracle@telde base_domain]$ ./startWebLogic.sh
JRMC	Now try to test connection again. Result should be
JRMC	Start the console and monitor CPU, Mem, seak for memory leaks, etc.

Resources

java.rmi.server.hostname (1.1 and later)

The value of this property represents the host name string that should be associated with remote stubs for locally created remote objects, in order to allow clients to invoke methods on the remote object. In 1.1.7 and later, the default value of this property is the IP address of the local host, in "dotted-quad" format.
