checking Weblogic status in Weblogic UNIX/Linux

[Ravi Kiran Va]

Hi we have weblogic deployed under Linux Enterprise 5 .

Now i want to write a script that checks if weblogic is running or not

I have found that weblogic uses Java as process .
Can i do this way :my Script File :

Echo Checking Status 
if [ps -ef | grep java ]
then
echo Server Running
else
echo Server Not  Running Do Something 
fi

Please correct me if i am wrong .I am posting here because there are other process that uses Java as their process status.

Why not hit an application URL and check if the server is up ? Netcat can do that for you

Deepak's suggestion is a good one. We use a commercial product, IP Monitor, to keep tabs on our server's external interfaces. To check the server process, I start the server with a bogus system property (this code is actually in startWebLogic.sh):

java -Dcheck.system.status.flag=admin_server    

This is on a Solaris system, so to get the command line for a process we run:

/usr/ucb/ps -axwww     

and then we grep through that output to find "admin_server".

Hi thanks all for replying ,
First of all sorry as i am not clear in my first post of this Thread.

My requirement is that i am using unix crontab for job scheduling that checks or runs this script for every 30 minutes .
So i need to dynamically check .

Any suggestions .

The solutions mentioned here can work with cron tab and make the checks dynamically. What part of the requirement is not met yet ?

If you would start the WLS with a command line like:

java -server -Dweblogic.Name=TheOne -Xms700m -Xmx750......

you can easily grep for "TheOne".

If you have a lot of managed Servers, and you use a naming scheme like: [prefix][number][number] (for example prod10) you could use a script like that (tested on Solaris with WLS 10.3):

 
  #put prefix here
  __domain="prod"

  # location of your config.xml
  __configFile="/wls/config/config.xml"

  # get all lines with servernames | remove blanks | remove double entrys | remove html-like tags | sort the output
  __servers=`grep \<name\>${__domain}[0-9,0-9] ${__configFile} |  tr -s '[:space:]' | uniq | sed -e :a -e 's/<[^>]*>//g;/</N;//ba' |sort`

  # walk through list of found servers
  for server in ${__servers}; do
    # list all processes | ignore all lines containing "grep" | look for a line like "java -server -Dweblogic.Name=prod10..."
    __test=`ps -ef | grep -v grep | grep -i "name=${server}"`

    # if ${__test} contains some text then the server was found in "ps -ef"
    if [ "${__test}" ] ; then
      echo "${server} is up"
    else
      echo "${server} is down"
    fi
  done
