(Oracle)自定义调用AWR

Oracle->自动发送AWR报告 2016年9月21日 09:31 需求描述：每日或定期手动使用AWR报告来检查Oracle数据库状态不仅耗时也费力，需求使用脚本自动收集AWR报告。

分析方案：　　收集AWR报告的脚本：$ORACLE_HOME/rdbms/admin/awrrpt.sql ->主要运行脚本。　　首先来查看脚本都做了写什么，用了哪些视图。 cat $ORACLE_HOME/rdbms/admin/awrrpt.sql |grep -v ‘Rem’|grep -v ‘^–‘ (排除‘Rem’和‘–’相关得到主要信息-> select d.dbid dbid , d.name db_name , i.instance_number inst_num , i.instance_name inst_name from v$database d, v$instance i; 和关联脚本@@awrrpti 再查看@@awrrpti脚本都执行了些什么 cat $ORACLE_HOME/rdbms/admin/awrrpt.sql |grep -v ‘Rem’|grep -v ‘^–‘ (排除‘Rem’和‘–’相关注释) 　　

得到核心内容->（这就是生成AWR报告的程序）

spool &report_name;
 
select output from table(dbms_workload_repository.&fn_name( :dbid,
                                                            :inst_num,
                                                            :bid, :eid,
                                                            :rpt_options ));
 
spool off;
 
select output from table(dbms_workload_repository.&fn_name( :dbid,:inst_num,:bid, :eid,:rpt_options ));
 
&fn_name->类型名称如awr_report_html和awr_report_text
:dbid->数据库id号
:inst_num->实例名
:bid->snap开始id
:eid->snap结束id
:rpt_options->控制显示ADDM

关联脚本 @@awrinput.sql ->主要获取snapshots id号 @@awrinpnm.sql ‘awrrpt_’ &&ext ->主要生成AWR报告名称 AWR生成脚本的流程： @awrrpt.sql（提供dbid和inst_num） @@awrrpti.sql(主程式脚本) @@awrinput.sql(提供snap id) @@awrinpnm.sql(提供awr生成名称) select output from table(dbms_workload_repository.&fn_name( :dbid,:inst_num,:bid, :eid,:rpt_options ));(生成awr报表) 制定脚本：<ora_auto_awrrpt.sql> 复制 @@awrrpti.sql内容并且加以更正就行

设定shell脚本定时执行并发送邮件。

针对脚本进行加密
使用shc工具 wget http://www.datsi.fi.upm.es/~frosal/sources/shc-3.8.7.tgz 参考http://www.thegeekstuff.com/2012/05/encrypt-bash-shell-script/
[root@xxx oracle]# tar xvfz shc-3.8.7.tgz
[root@xxxx shc-3.8.7]# ./shc -r -f oracle_auto_awr.sh ->对shell脚本进行加密 oracle_auto_awr.sh ->(原文件) oracle_auto_awr.sh.x ->(二进制文件) oracle_auto_awr.sh.x.c ->（C语言）
shc常用参数： -e date Expiration date in dd/mm/yyyy format [none]（指定过期日志） -m message Message to display upon expiration [“Please contact your provider”]（指定提示的信息） -f script_name File name ofr the script to complie（指定要编译的shell路径及文件名） -f Relax security. Make a redistributable binary which executes on different systems run（可以相同操作系统的不同系统中执行） -V Verbose compilation（编译的详细情况）参考： http://blog.csdn.net/tianlesoftware/article/details/6319198 http://blog.itpub.net/12457158/viewspace-753875/
