    How to avoid starting JBoss AS, if already running

    Farhan Khan Newbie

      Hello,

      I want to configure my JBoss so that if another instance is laready running on the same machine, then it should not start. How can I do that ??? Currently, it start another instance on some other port.

      Thanks in advance
      Farhan !

          Are you sure it starts successfully? I would expect the second instance to fail to start when the first one is already running (and if you have not configured a different set of ports for the second instance).

            Thanks for your prompt response. Please see the server logs as following. My requirement is that if the server is already running, then another instance should not start, instead it should give a message and exit.

              Peter Johnson Master

              There is no way to do this within JBoss AS itself. However, the run script is, after all, just a script. You can modify the script to test if another instance is running first, either by examining the existing processes or using a "lock" file. How you do either of those depends on the operating system.

                I have Linux Fedora Core 9 installed on my server. Would you please guide me through the steps to modify the run script. I would really appreciate if you provide me some sample script.

                Thanks in advance.
                Farhan !

                  Too bad you are not running Windows or I would have pointed you to the service.bat script (comes with JBoss AS 5.0 and with JBoss Native). That script uses a lock file to prevent multiple runs.

                  For Linux, look at the jboss_home/bin/jboss_init_hpux.sh script. It greps the output from ps looking for a JBoss AS instance running. I don't know if you can use that script as-is on Fedora, but if not you should be able to use the code that does the isJBossRunning check as an example for writing your own code.

                    Farhan Khan Newbie

                    Thankyou Peter ! I have solved the problem by adding the following to my runJBoss.sh script

                    jbossRunning=$(ps -ef | grep "sh runJBoss.sh" | grep -vc grep)
                    echo "jbossRunning = " $jbossRunning

                    if [ $jbossRunning -gt 2 ]; then
                    die "Already running JBoss . . . Going to exit"
                    else
                    warn "No instance running. Going to start this"
                    fi

                    I would also try the other method that you mentioned.

                    Thanks a lot
