oracle数据库状态监控

1、功能介绍     1、检查oracle数据库的运行状态     2、第一次失败后，等待5秒钟再次检查一次 2、脚本

#!/bin/bash
source /etc/profile
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
w=$(cd $(dirname $0);pwd)

#检查数据库的方法
fun(){
result=$(sqlplus -s ${user}/${pass}@${database} <<EOF
WHENEVER SQLERROR EXIT FAILURE ROLLBACK
SET HEADING OFF
SET FEEDBACK OFF
SET VERIFY OFF
${sql_query}
EOF
)
new_result=$(echo "$result"|tr -d '[:space:]')

#判断结果情况
if [[ $new_result -eq 'OPEN' ]];
   then
     echo oracle数据库${hj}'连接成功'
   else
     echo oracle数据库${hj}'连接失败' >>$w/online-check-tmp.txt
fi
