Oracle AWR报告提取方法

本文旨在用来指导项目人员自行提取Oracle数据库的AWR报告.

1.当前连接实例的AWR报告提取：@?/rdbms/admin/awrrpt

2.RAC的其他实例AWR报告提取：@?/rdbms/admin/awrrpti

3.手工生成一个快照 

1.当前连接实例的AWR报告提取：@?/rdbms/admin/awrrpt

SQL> @?/rdbms/admin/awrrpt //注意输入的@?/rdbms/admin/awrrpt 中间没有任何空格，需要在数据库服务器上Oracle用户登陆，sqlplus / as sysdba 进入SQL> 下执行.
