Linux上的oracle巡检脚本

修改自dba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
