最近几天被厂商的数据库弄得头大，他们应用一小时能跑2TB的读数据出来
百度了一把搜索到了sql monitor这个工具出来，学习了一下
改成了脚本，执行以后会在/home/oracle目录下面生成badsql.txt文件，用more命令就可以看了
vi badsql.sh
添加下如内容
#!/bin/bash
su - oracle<<EOF
sqlplus / as sysdba
spool badsql.txt
col status fro a15
col username for a10
col module for a20
col PROGRAM for a20
set linesize 1000
set pagesize 300
select status,username,module,program,sql_id,PHYSICAL_READ_BYTES/1024/1024 READ_IO_MB,sql_text from v\$sql_monitor order by PHYSICAL_READ_BYTES desc;
spool off;
exit;
EOF
保存退出
打开badsql.txt文件
取出里面的sql_id，代入到下面的命令，就能出现详细的报告了
su - oracle
more badsql.txt
