Oracle批量导出AWR报告

Oracle批量导出AWR报告

工作需求：项目中需要把生产库中所有的AWR报告dump出来，然后导入到方便测试的数据库中。在测试库中的AWR报告需要根据dbid和实例名逐个导出，如果遇到很多再加上RAC系统，会很麻烦。在网上找了一些脚本，发现没有适合自己的，所以就自己学习了一个存储过程来实现这样的功能。

说明：在$Oracle_HOME/rdbms/admin/awrrpti.sql中可以看到，生成AWR报告主要使用DBMS_WORKLOAD_REPOSITORY.awr_report_html包。至于喜欢玩哪种方式，要看个人偏好。

Oracle AWR报告生成与查看

在CentOS 6.4下安装Oracle 11gR2(x64)

Oracle 11gR2 在VMWare虚拟机中安装步骤

Debian 下 安装 Oracle 11g XE R2

存储过程实现代码：

create or replace directory AWR_REPORTS_DIR as '/u01/awr/';
DECLARE

  l_file            UTL_FILE.file_type;
  l_file_name        VARCHAR(50);
  cursor cur_inum is  SELECT instance_number FROM dba_hist_snapshot WHERE dbid = l_dbid GROUP BY instance_number ORDER BY instance_number;
