Weblogic - List running instances

Unix-List all instances of weblogic instances running on a server

At times we need to find the weblogic instances which are up and running on a particular machine mostly in clustered environments. This might be required to figure out weblogic process from a particular domain and kill that process.

You can do a grep as below which gives all the Java processes running on the machine and it may be tough to correlate PID with the running server instances.

$ps -ef | grep java 

Below shell script can be handy to list down the servers running on a particular machine.

clear

echo "PID and  webLogic instances"

echo  "**************************************"

/usr/ucb/ps -awwx | grep "weblogic.Name" | grep -v "grep weblogic.Name" | nawk 'BEGIN {print "PID\tWeblogicServer";

print  "**************************************" } ;

        {

        NUM = match($0, "weblogic.Name=") ;

        START_POS  = RSTART+RLENGTH ;

        START_STR = substr($0, START_POS) ;

        FINISH = match(START_STR, " ") ;

        FINISH_POS = START_POS+RSTART+RLENGTH ;

        FINISH_STR = substr($0, START_POS, FINISH_POS) ;

        NUM = split(FINISH_STR,FINISH_ARRAY) ;

        printf ("%s\t%s\n",$1, FINISH_ARRAY[1]) ;

        }

        END {

        print "**********************************"}'

Below is a sample output.

PID and  webLogic instances

**************************************************

PID     WeblogicServer

**************************************************

12624   AdminServer

13367   wls_soa1

13369   wls_wsm1

**************************************************

To stop a particular server issue the below.

$ kill -9 PID

If it's admin server,to avoid the conflict of existing .lok and .DAT files you can remove the tmp and cache folders or rename them.

Another handy way to find the running process will be using the jps script in the java bin folder. For example navigate to /usr/local/java/bin and run $jps -v which gives the server name in the parameter weblogic.Name  as below.
