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:

DECLARE

l_dir VARCHAR2(50) := 'AWR_REPORTS_DIR';
l_last_snap NUMBER := NULL;
l_dbid NUMBER := 813977229;
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;
BEGIN
for l_instance_number in cur_inum loop
l_last_snap := NULL;
FOR cur_snap IN (SELECT snap_id

l_file := UTL_FILE.fopen(l_dir, 'awr_' ||l_instance_number.instance_number||'_'|| l_last_snap || '_' || cur_snap.snap_id || '.html', 'w', 32767);
FOR cur_rep IN (SELECT output

LOOP
UTL_FILE.put_line(l_file, cur_rep.output);
END LOOP;
UTL_FILE.fclose(l_file);
END IF;
l_last_snap := cur_snap.snap_id;
END LOOP;
end loop;
