Server & NodeManager Listing

 Following script will display the details on machine Server Name, Process owner, Process ID and NodeManager:

#!/bin/ksh

echo "################################################################################"
echo "# WebLogic Servers"
echo "#  [owner]  [server]  [pid]   "
echo "################################################################################"
ps -ef | grep "[D]weblogic.Name="|while read tmp
do
  owner=`echo $tmp | awk '{ print $1 }'`
  webLogicServer=`echo $tmp | grep -oP "(?<=Dweblogic.Name=)[^ ]+"`
  pid=`echo $tmp | awk '{ print $2 }'`
    echo "$owner $webLogicServer $pid $port"
done|sort|column -t

echo
echo "################################################################################"
echo "# Node Managers"
echo "#       "
echo "################################################################################"
ps -ef | grep "[w]eblogic.NodeManager"|while read tmp
do
  owner=`echo $tmp | awk '{ print $1 }'`
  pid=`echo $tmp | awk '{ print $2 }'`
  port=`echo $tmp | netstat -tlpn 2>/dev/null | grep $pid | awk '{ print $4 }' | tr '\n' ',' | tr ' ' ',' | grep -o ":....," | sort -u | tr -d '\n' | tr -d ':' | sed 's

  if [ -z "$port" ]; then
    port="null"
  fi
  mw_home=`echo $tmp | grep -oP "(?<=bea.home=)[^ ]+"`
    echo "$owner $mw_home $pid $port"
done|sort|column -t

exit 0

Output will be like this:

Getting State of all Servers in a domain

First you may create secure key files to avoid using plain text uname and password for weblogic.

Step1:

Run WLST --> /opt/admin/fmw/oracle_common/common/bin/wlst.sh

Initializing WebLogic Scripting Tool (WLST) ...

Welcome to WebLogic Server Administration Scripting Shell

Type help() for help on available commands

wls:/offline>connect('weblogic','welcome1',url='t3://localhost:7001')
wls:/myDomain/serverConfig> storeUserConfig('/tmp/myUserConfigFile','/tmp/myUserKeyFile')
wls:/myDomain/serverConfig> exit()

Step2:

File name: getAllServerStatus.py

import sys
import os

connect(userConfigFile='myUserConfigFile', userKeyFile='myUserKeyFile', url='t3://localhost:7001')
domainRuntime()
cd('ServerRuntimes')

sServers=domainRuntimeService.getServerRuntimes()
for sServer in sServers:
     serverName=sServer.getName();
     print '###' , serverName,'State is:', sServer.getState()

disconnect()
exit()

Step3:

FileName: getAllServerState_wls.sh

#!/bin/ksh

echo "Getting All Servers State......"

/opt/admin/fmw/oracle_common/common/bin/wlst.sh getAllServerStatus.py > /tmp/allServerStatus.log

cat /tmp/allServerStatus.log | grep -i state

exit 0

Example Run:

./getAllServerState_wls.sh

Getting All Servers State......
### AdminServer State is: RUNNING

Clean up Weblogic Server Cache

In many situations we would need to clean up weblogic server cache and we need to be careful while doing this. It's better to have a script which can do our job can help in reducing manual effort/human errors.

Following script can be run using 2 parameters (domain name & server name). This is required because there may be multiple domains in one machine and server name needs to mentioned as we can clean-up any server depending on the need basis.

clearWLCache.sh 

#!/bin/ksh

usage()
{
 echo "\n!!!!!Usage!!!!!!!"
 echo
 echo " clearWLCache.sh "
 echo "\ne.g. clearWLCache.sh myDomain myServer"
 echo
}

if [ $# -ne 2 ]
then
 usage
 exit 2
fi

domain=$1
server=$2
WLS_HOME=/opt/fmw

state=`cut -f1 -d ":" $WLS_HOME/domains/${domain}/servers/${server}/data/nodemanager/${server}.state`
echo "Server state is $state"

if [ $state = RUNNING -o $state = STARTING ]
then
    echo "Server is in $state mode, please shutdown and then use this script "
    exit
else

 if [ -d $WLS_HOME/domains/${domain}/servers/${server} ]
 then
   path=$WLS_HOME/domains/${domain}/servers/${server}
   rm -Rf $path/cache/*
   rm -Rf $path/tmp/*
   echo "Cache clean-up completed successfully"
   exit
 else
   echo ${domain} "or" ${server} "doesn't exists, please check"
   exit
 fi

fi

echo "There was some error, script not executed, please check the command/server name/admin name"
exit

Useful Scripts

Following script is used to clean up the logs by executing the script with 2 parameters (domain name & server name)

cleanLogs.sh

#!/bin/ksh

usage()
{
 echo "\n!!!!!Usage!!!!!!!"
 echo
 echo " cleanLogs.sh "
 echo "\ne.g. cleanLogs.sh mydomain myServer"
 echo
}
if [ $# -ne 2 ]
then
 usage
 exit 2
fi

domain=$1
server=$2
FMW_HOME=/opt/fmw/

#Remove the logs older than 30 days
find $FMW_HOME/user_projects/domains/${domain}/servers/${server}/logs/*_log.* -mtime +30 | xargs rm

#Compress the logs older than 15 days
find $FMW_HOME/user_projects/domains/${domain}/servers/${server}/logs/*access_log.* -mtime +15 | xargs compress
