Oracle 数据库日常巡检脚本，通用版， 主要是资源使用情况，可增加导出awr等相关报告，后续优化，如有题问题，可联系我，
具体脚本如下:
#!/bin/bash
#=====================================================
# summary: Daily check script,eg:tablespace resource usage info
# note:root_exec.linux:/bin/bash unix:/usr/bin/ksh
# support: Oracle10g/11g linux/aix/unix
# default logfile: /opt/xunjian/logs
# 2020/03/27, modify listener_time and display format
# 2020/05/08, modify if statement bug,find listenerlog_11g
# 2021/10/14,modify Output format and environment variable
