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
### my_server1 State is: RUNNING
### my_server2 State is: RUNNING
