wlst script example to start, stop and run as service

Below are the wlst script example which you can use in combination to make weblogic a service and automate the start/stop of Admin servers , managed servers and Node manager.

Create a folder at your server for ex: /opt/WLS/scripts/ where you will store all your scripts.

There are 5 scripts

MainWLS.sh : Script to manually start/stop all servers(including nodemanager). Can be used in /etc/init.d so that after system/machine reboot also the weblogic servers will comeup automatically.

Commands: MainWLS.sh start|stop

#! /bin/bash
#
# description: Oracle Weblogic auto start-stop script.

# Source function library.
. /etc/init.d/functions

MW_HOME="/u01/app/oracle/middleware"
DM_HOME="/u02/weblogic/user_projects/domains/base_domain"

JAVA_OPTIONS="-Dweblogic.security.SSL.ignoreHostnameVerification=true"

fileDate=`date '+%F_%H%M'`
RETVAL=0
start() {
export MW_HOME DM_HOME JAVA_OPTIONS
logFileName=nodemanager.log.$fileDate
nohup $MW_HOME/wlserver_10.3/server/bin/startNodeManager.sh > $MW_HOME/logs/$logFileName &

chown oracle:oinstall $MW_HOME/logs/$logFileName
su oracle -c '/opt/WLS/scripts/startServers.sh'
return $RETVAL
}

stop() {
export MW_HOME DM_HOME JAVA_OPTIONS
su oracle -c '/opt/WLS/scripts/stopServers.sh'
return $RETVAL
}
case "$1" in
start)
start
;;
stop)
stop
;;
*)
echo $"Usage: $0 {start|stop}"
exit 1
esac

exit $?

Above wlst script example can be used as a linux/*NIX service to start servers using “chkconfig –add servicename”
The above MainWLS.sh script refers 3 script files for starting servers.

startNodeManager.sh -> Provided by Oracle. ($MW_HOME/wlserver_10.3/server/bin/) -> Starts Nodemanager
startServers.sh -> We will create it in below section to start all servers including Admin and Managed.
stopServers.sh -> We will create it in below section to stop all servers including Admin and Managed.

Now we will create startServers.sh script to start all servers.(Admin and Managed)

startServers.sh:

#Shell to start Admin Server First.
export JAVA_OPTIONS="-Dweblogic.security.SSL.nojce=true\
-Dweblogic.security.SSL.ignoreHostnameVerification=true"
export PRE_CLASSPATH="${MW_HOME}/wlserver_10.3/server/lib/jsafeFIPS.jar"
export USER_MEM_ARGS="-Xms1280m -Xmx1280m -XX:MaxPermSize=256M"
export LOG_DIR="${MW_HOME}/logs"
export WLS_REDIRECT_LOG=${LOG_DIR}/AdminServer.log
#echo "Starting admin server"
mv ${WLS_REDIRECT_LOG} ${WLS_REDIRECT_LOG}.`date +%F_%H%M`
#
# start the WLS admin server.
#
nohup $DM_HOME/startWebLogic.sh &
#
# once Admin Server is started, now we can start all the managed servers
#
echo `env` >> $MW_HOME/logs/startup.log
source $DM_HOME/bin/setDomainEnv.sh
#
#Below startMS.py python script is used to start all the managed servers present in your domain(Ex: base_domain).
#
java weblogic.WLST /opt/WLS/scripts/startMS.py

Above script startServers.sh refers startMS.py python script to start all the managed servers.
Please find the python code for startMS.py

startMS.py:

import time
sleep=time.sleep
configFile = "/u02/weblogic/user_projects/domains/base_domain/userConfig.dat"
pwFile = "/u02/weblogic/user_projects/domains/base_domain/userKey.dat"
while True:
try:
connect(userConfigFile=configFile,
userKeyFile=pwFile,
url='t3://my.Adminserver.com:7001')
break
except:
sleep(60)
nmConnect(userConfigFile=configFile,
userKeyFile=pwFile,
domainName='base_domain')
nmStart('ManageServer1')
nmStart('ManageServer2')
exit()

you can see I have given configFile and Password file instead of username and password for better security.
You can also create you own secured/encrypted secure file using wlst.
Tips:

When you use this command with no arguments the user configuration file for the current user will be generated within the current OS user’s home folder.

wls:/testdomain/serverConfig>storeUserConfig()

All above scripts were for starting Adminserver, Nodemanager and Managed servers.

Now we will see the stop part scripts for AdminServer, managed servers.
stopServers.sh -> Referenced in MainWLS.sh

cd /opt/WLS
source $DM_HOME/bin/setDomainEnv.sh
java weblogic.WLST /opt/WLS/scripts/stopMS.py
exit

stopMS.py -> Python script to stop Managed servers, Admin server and Nodemanager

configFile = "/u02/weblogic/user_projects/domains/base_domain/userConfig.dat"
pwFile = "/u02/weblogic/user_projects/domains/base_domain/userKey.dat"
connect(userConfigFile=configFile,
userKeyFile=pwFile,
url='t3://my.AdminServer.com:7001')
nmConnect(userConfigFile=configFile,
userKeyFile=pwFile,
domainName='base_domain')
print " shutting down managed servers"
shutdown('ManageServer1',force='true')
print " ManageServer1 shutdown"
shutdown('ManageServer2',force='true')
print " ManageServer2 shutdown"
print "Shutting down Admin Server"
shutdown('AdminServer',force='true')
print "Stopping node manager"
stopNodeManager()
exit()
