# Modify classpath to as per the weblocic server location in your environment
# The script takes 3 parameters
# The first parameter is the admin url
# The second parameter is the Username of admin server
# The third parameter is the password of admin server

Problem Description This script can be used to restart the weblogic server using crontab in unix without any manual intervention.

Solution Description This script can be used to restart the weblogic server without any manual intervention. It also sends email to the list of people once the restart is done.We can add few more manipulations if you need before restarting the weblogic server. This can be enabled through crontab in the unix.

Code Snippet

#! /bin/ksh

#This script is used for restarting the Weblogic server using CRONTAB

#-------------------------------------------------------------------

# Mail list is used to email the list of users once the restart is done

Maillist=" "

# Mail file is the file which will get emailed to the mail list users

Mailfile= " "

#This is the temporary log file where stopWeblogic.sh result will be stored

> Stop_log

# Stopping the Server

echo "Stopping Weblogic server"

. ./stopWebLogic.sh > Stop_log 2>& 1

sleep 90

echo "Confirming that the Weblogic server stopped"

. ./stopWebLogic.sh >> Stop_log 2>& 1

# Searching for the exception when you shut down the weblogic server for the second time

egrep '[Destination unreachable | "OPUSServer" was shutdown successfully]' Stop_log > /dev/null

if [ $? -eq 0 ]

then

echo "Weblogic server stopped successfully"

# Starting the Server

echo "Trying to start Weblogic server"

#. ./startWebLogic.sh > Start_log 2>& 1 &

. ./startWebLogic.sh > /dev/null

#Getting the process id for startWebLogic.sh process

id=$!

if [ $? -eq 0 ]

then

echo "Weblogic server started successfully"

#Killing the process startWebLogic.sh using process id

#kill -9 $id

#echo "Killed startweb"

break

done

if [ $i -ne 2 ]

then

Server dosent come up if deployment fails	Server boots in ADMIN mode if deployment failes

You can add a startup script to your UNIX rc scripts to run WebLogic Server at UNIX boot time. Here is an example from an HP-UX 11 system, running under JDK 1.1. You need to supply the URL for your WebLogic Server and your system password. This file, wlstart, is placed in the /sbin/init.d directory and there is a link to it in the /sbin/rc2.d directory:

export SHLIB_PATH=\
/home/user1/weblogic/lib/hpux11:/oracle/8.0.4/lib
export CLASSPATH=/home/user1/weblogic/classes:\
/home/user1/weblogic/lib/weblogicaux.jar
export ORACLE_HOME=/oracle/8.0.4
export ORACLE_SID=DEMO
export ORACLE_TERM=vt100
export QAT=/home/user1/weblogic
cd $QAT
PATH=/sbin:/usr/sbin:/usr/bin:/opt/java/bin
export PATH
case $1 in
'start')
java -ms64m -mx64m -verbosegc weblogic.Server > \
/home/user1/weblogic/server.out 2> #emp;
;;
'stop')
java weblogic.Admin URL shutdown system password
;;
*)
echo "usage: $0 {start|stop}"
;;
esac

You should work with your UNIX system administrator to set up scripts similar to this for your system.
