定期訪問WebLogic Server返回狀態的腳本

在運維過程中,經常要獲悉WebLogic Server的狀態以便於主動的維護,本文通過weblogic WLST腳本初步設計了一下

腳本大概為2個,一是WLST的py腳本,getStates.py

connect('weblogic','weblogic12','localhost:7001')
serverRuntime()
state('AdminServer')

另一個是linux的sh腳本

#!/bin/bash
. /home/weblogic/Oracle/Middleware/user_projects/domains/base_domain/bin/setDomainEnv.sh
cd /home/weblogic/WLST
while [ true ]; do
/bin/sleep 60
java weblogic.WLST /home/weblogic/WLST/getStates.py > /home/weblogic/WLST/result.log
result=$(grep "RUNNING" /home/weblogic/WLST/result.log | wc -l)

echo "*************** $result"
if [ "$result" = "1" ]; then
echo "Connecting successfully"
else
echo " ======= Connecting fail ========"
fi

done

腳本為沒隔1分鍾去訪問一下weblogic server的AdminServer,獲取狀態信息,並把結果輸入到result.log

在實際的生產環境中,基本可以設置為5分鍾或者10分鍾定期訪問一下

另外需要注意的是,在網絡不是太穩定狀態下,建議修改腳本,5分鍾訪問如果失敗,再等5分鍾再訪問一次,如果還是失敗,就再等5分鍾再訪問一次,如果三次訪問

失敗,觸發后續的操作.

后續操作可以是echo,或者發郵件,或者調用api發短信到手機的模式.

試驗了一下,運行不多久把weblogic server直接給停了,輸出如下:

[weblogic@dockervm WLST]$ sh getStates.sh

*************** 1

*************** 1
