runtime JVM options

[Victor Cheung]

I just did a ps and got the following:

13301 pts/1    00:00:00 bash
13796 pts/1    00:00:00 ps

Jps gives me the following:

13974 Jps


My unix account does not have permission to see any processes but my own...

It is a JBoss web application.

I also tried:

jinfo -flags localhost
jinfo -flags 127.0.0.1

But got the following:

Attaching to remote server localhost, please wait...
Error attaching to remote server: java.rmi.ConnectIOException: non-JRMP server at remote endpoint

[~]$ jinfo

Usage: jinfo [option] <pid>
                (to connect to a live java process)
    or jinfo [option] <executable> <core>
                (to connect to a core file)
    or jinfo [option] [server_id@]<remote server IP or hostname>
                (to connect to a remote debug server)

where option must be one of:
     -flags     to print VM flags
     -sysprops  to print Java System properties
     <no option>        to print both of the above
     -h | -help to print this help message
