JVM Already Bind-When try to start server with degub port

[abhijitprusty]

Hi All,

I have a Jboss server running with two nodes using the following command, now I have added the below mentioned line to the run script. Now when I start my first node. it starts fine.When I try to run my second node, it gives JVM already in use error as the debug port added to run script i.e. 8787 is already started.

-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n

Can any one suggesst me how, can I handle this scenario.

Thanks,

Abhiji

If you have two nodes started on the same server and add the -Xrunjdwp option the address must be different.

This connection port will be opened by the JVM to connect the remote-debugger and it must be unique.

Hi Wolf,

Can you let me know how can I mention two different port.

Thanks,

How do you start the JBoss instances?

I suppose you add "-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n" to both run.conf[.bat] right?

You can't use 8787 port twice, try a different one.

For the debugger you have to decide which instance do you want.

BTW it will be difficult to debug with two instances

I start using the run.bat file, but to run both instances I ahve only one run.bat file. Do I need to add the degug line twice with different ports? Is it possible to make separate run.bat for the different isntances

PFA for my run.bat

Thanks,

Abhijit

You might do this with a copy of run.bat.

I think you will run two instance for development right?

But why you need two for debugging?

That was a great help. It's the exactly what I wantred..:)
