Linux上的oracle巡检脚本

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Linux上的oracle巡检脚本相关的知识,希望对你有一定的参考价值。

修改自大神博客:http://www.cnblogs.com/jyzhao/p/5364049.html

 脚本巡检的优化:自动化,节省时间。

 脚本需加强:巡检结果中有大量的sqlplus连接信息,后期考虑用shell只过滤出有用信息,优化查看。

 

开始介绍:

1.环境sentos6\\7、redhat6

2.可以将脚本放至/home/oracle/checkdir/ORA_check.sh

3.修改脚本文件权限:

# chown -R oracle:dba /var/ORA_check.sh
# chmod u+x ORA_check.sh

4.vim ORA_check.sh

#!/usr/bin/ksh

echo "ORAWatcher Version:1.0.1"
