使用RDA巡檢MYSQL資料庫

RDA(RemoteDiagnostic Agent)是oracle用來收集、分析資料庫的工具，執行該工具不會改變系統的任何引數，RDA收集的相關資料非常全面，可以簡化我們日常監控、分析資料庫的工作。
一般Oracle 原廠的人巡檢也是使用RDA工具。 不過一般國內的DBA 巡檢時很少使用這個工具，一般都是透過AWR 或者自己整幾個指令碼，跑了在分析一下就ok了。
在MOS 上建立SR(Service Request)時（我08年剛接觸Oracle時，那是MOS 上還是稱呼Tar，後來改成了SR了）。 Oracle 也會要求客戶上傳RDA的資訊。 透過RDA 可以快速的瞭解系統的狀況。
RDA 是用Perl 指令碼寫出來的。 可以透過MOS 下載RDA。 RDA 是一個客戶端，解壓縮之後就可以直接使用了。
同樣RDA也可以對mysql資料庫進行簡單的檢查，並生成檢查報告。

  You can review the reports by transferring the
  /data/mysqldata/scripts/rda/output directory structure to a location where
  you have web-browser access. Then, point your browser at this file to
  display the reports:
    RDA__start.htm


  Based on your server configuration, some possible alternative approaches
  are:
  - If your client computer with a browser has access to a web-shared
    directory, copy the /data/mysqldata/scripts/rda/output directory structure
    to the web-shared directory and visit this URL:
   
  or
  - If your client computer with a browser has FTP access to the server
    computer with the /data/mysqldata/scripts/rda/output directory, visit this
    URL:
    ftp://root@jing1.jing1//data/mysqldata/scripts/rda/output


  If this file was generated to assist in resolving a Service Request, send
  /data/mysqldata/scripts/rda/RDA_output_jing1.zip to Oracle Support by
  uploading the file via My Oracle Support. When sending with FTP, make sure
  you send it in BINARY format.


  Note: Do not submit any health, payment card or other sensitive production
  data that requires protections greater than those specified in the Oracle
