【RDA】使用RDA（Remote Diagnostic Agent）工具對資料庫進行健康檢查

secooler發表於2010-03-05
REM資料庫
RDA英文全稱叫做“Oracle Remote Diagnostic Agent”。
這個Oracle診斷工具是用perl編寫的，包含非常豐富的診斷指令碼，使用它可以非常便利的採集到Oracle資料庫伺服器系統配置和資料庫的詳細資訊。
如果您在向Oracle支援人員尋求幫助時能夠提供一份RDA報告，將會大大的縮短問題處理的週期，避免資訊的反覆採集。
RDA不會更改資料庫伺服器的任何配置，僅僅是採集資訊，瞭解系統。大家可以放心使用RDA工具。

這篇文章給大家介紹一下這個RDA工具的使用方法，供參考。

1.下載RDA安裝包
參考MOS（Metalink Note）：314422.1
“Remote Diagnostic Agent (RDA) 4 - Getting Started [ID 314422.1]”文章中提供了不同作業系統版本的介質下載。
這裡選擇“Linux x86 (64-bit)”版本進行演示操作。

該工具支援以下作業系統：
Apple Mac OS X
HP OpenVMS
HP Tru64
HP-UX Itanium
HP-UX PA-RISC (32-bit)
HP-UX PA-RISC (64-bit)
IBM AIX on POWER Systems (32-bit)
IBM AIX on POWER Systems (64-bit)
IBM Dynix/Ptx
IBM Linux on POWER
IBM zSeries Based Linux
Linux Itanium
Linux x86 (32-bit)
Linux x86 (64-bit)
Microsoft Windows (32-bit)
Microsoft Windows (64-bit)
Sun Solaris Intel (32-bit)
Sun Solaris Intel (64-bit)
Sun Solaris SPARC (32-bit)
Sun Solaris SPARC (64-bit)

2.在資料庫伺服器上建立一個RDA目錄
建立的RDA目錄需要保證有足夠的空間可用。
ora10g@secDB /home/oracle$ mkdir RDA

3.將下載到的安裝檔案上傳到伺服器上
$ scp p9079828_418_LINUX.zip oracle@172.17.193.211:/home/oracle/RDA
oracle@172.17.193.211's password:
p9079828_418_LINUX.zip                     100%   26MB   8.8MB/s   00:03

4.解壓檔案
1）解壓
ora10g@secDB /home/oracle/RDA$ unzip p9079828_418_LINUX.zip
Archive:  p9079828_418_LINUX.zip
  inflating: readme.txt
   creating: rda/
   creating: rda/RDA/
... 此處省略大量解壓資訊 ...
  inflating: rda/rda_linux56
   creating: rda/ccr/
  inflating: rda/ccr/ccr-Production-10.3.2.0.0-Linux-i386.zip

2）解壓後，當前目錄下將會建立一個rda目錄和一個readme.txt檔案
ora10g@secDB /home/oracle/RDA$ ls -ltr
total 27M
-r--r--r-- 1 oracle oinstall   48 Dec  4 14:45 readme.txt
drwxr-xr-x 6 oracle oinstall 4.0K Dec  4 14:45 rda/
-rwx------ 1 oracle oinstall  27M Mar  5 02:07 p9079828_418_LINUX.zip*

3）readme.txt檔案記錄了RDA軟體的版本資訊
ora10g@secDB /home/oracle/RDA$ vi readme.txt
RDA/OCM bundle for RDA 4.18-091204 for linux_x86
~

5.驗證RDA工具安裝是否成功
1）第一種方法
ora10g@secDB /home/oracle/RDA/rda$ perl rda.pl -cv
Loading the file list ...
Checking the directory '.' ...
Checking the directory 'RDA' ...
Checking the directory 'RDA/Handle' ...
Checking the directory 'RDA/Library' ...
Checking the directory 'RDA/Library/Remote' ...
Checking the directory 'RDA/Local' ...
Checking the directory 'RDA/Object' ...
Checking the directory 'RDA/Operator' ...
Checking the directory 'RDA/Value' ...
Checking the directory 'hcve' ...
Checking the directory 'modules' ...
No issues found

2）第二種方法
ora10g@secDB /home/oracle/RDA/rda$ rda.sh -cv
Loading the file list ...
Checking the directory '.' ...
Checking the directory 'RDA' ...
Checking the directory 'RDA/Handle' ...
Checking the directory 'RDA/Library' ...
Checking the directory 'RDA/Library/Remote' ...
Checking the directory 'RDA/Local' ...
Checking the directory 'RDA/Object' ...
Checking the directory 'RDA/Operator' ...
Checking the directory 'RDA/Value' ...
Checking the directory 'hcve' ...
Checking the directory 'modules' ...
No issues found

經檢查，RDA工具安裝沒有問題。

6.配置並執行RDA
1）驗證perl是否可用
ora10g@secDB /home/oracle/RDA/rda$ perl -V

2）保證rda.sh和rda.pl兩個檔案具有執行許可權
ora10g@secDB /home/oracle/RDA/rda$ ls -l rda.sh rda.pl
-r-xr-xr-x 1 oracle oinstall  47K Nov 30 16:02 rda.pl*
-r-xr-xr-x 1 oracle oinstall 3.5K Jan 14  2009 rda.sh*

如果不具有執行許可權，可以使用下面的命令進行調整。
ora10g@secDB /home/oracle/RDA/rda$ chmod +x rda.sh rda.pl

3）使用“-L modules”選項列出所有可供採集的模組
通過下面的這個列表體現出了RDA在資料庫採集方面的強大優勢。
ora10g@secDB /home/oracle/RDA/rda$ ./rda.sh -L modules

4）我們選擇四個模組（OS DB DBA INST）配置一下
只要按照提示的資訊進行配置即可，基本上都可以使用預設設定的內容。
需要注意的是最後兩步我們這裡輸入“/”和“Y”，目的是在執行RDA採集資訊的過程中不需要輸入密碼，避免互動操作。
ora10g@secDB /home/oracle/RDA/rda$ ./rda.sh -S OS DB DBA INST
-------------------------------------------------------------------------------
S000INI: Initializes the Data Collection
-------------------------------------------------------------------------------
RDA uses the output file prefix to identify all files belonging to the same
data collection. The prefix must start with a letter and must contain only
alphanumeric characters.

Enter the prefix to be used for all the generated files
Hit 'Return' to accept the default (RDA)
>

Enter the directory used for all the files to be generated
Hit 'Return' to accept the default (/home/oracle/RDA/rda/output)
>

Do you want to keep report packages from previous runs (Y/N)?
Hit 'Return' to accept the default (N)
>

> localhost.localdomain

-------------------------------------------------------------------------------
S010CFG: Collects Key Configuration Information
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
S090OCM: Set up the Configuration Manager Interface
-------------------------------------------------------------------------------
RDA benefits from Oracle Configuration Manager by improving its data
collection. Oracle Configuration Manager (OCM) collects the configuration
information and uploads it to the OCM Repository in connected mode. When OCM
is configured in disconnected mode, it adds the OCM payload to the RDA report
packages in future RDA runs.

Select the mode that you want to install Oracle Configuration Manager in
/oracle/app/oracle/product/10.2.0/db_1
  C  Connected Mode
  D  Disconnected Mode
Enter the letter corresponding to your choice
Hit 'Return' to accept the default (C)
>

Do you want to install OCM Database collection scripts (Y/N)?
Hit 'Return' to accept the default (Y)
>

Enter a SYSDBA user for installing the OCM Database collection scripts
Hit 'Return' to accept the default (sys)
>

Is /oracle/app/oracle/product/10.2.0/db_1 an Oracle E-Business Suite Database
Oracle home (Y/N)?
Hit 'Return' to accept the default (N)
>

-------------------------------------------------------------------------------
S909RDSP: Produces the Remote Data Collection Reports
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
S919LOAD: Produces the External Collection Reports
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------

-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
S100OS: Collects the Operating System Information
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
S130INST: Collects the Oracle Installation Information
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
S200DB: Controls RDBMS Data Collection
-------------------------------------------------------------------------------
Is there a database for RDA to analyze (Y/N)?
Hit 'Return' to accept the default (Y)
>

Is the database associated to the current Oracle home (Y/N)?
Hit 'Return' to accept the default (Y)
>

Enter the Oracle SID to be analyzed
Hit 'Return' to accept the default (ora10g)
>

Is the INIT.ORA for the database to be analyzed located on this system? (Y/N)
Hit 'Return' to accept the default (Y)
>

Enter the location of the spfile or the INIT.ORA (including the directory and
file name)
Hit 'Return' to accept the default
(/oracle/app/oracle/product/10.2.0/db_1/dbs/spfileora10g.ora)
>

Enter an Oracle User ID (userid only) to view DBA_ and V$ tables. If RDA will
be run under the Oracle software owner's ID, enter a forward slash (/) here,
and enter Y at the SYSDBA prompt to avoid a prompt for the database password
at runtime.
Hit 'Return' to accept the default (system)
> /

Is '/' a SYSDBA user (will connect as SYSDBA) (Y/N)?
Hit 'Return' to accept the default (N)
> Y

-------------------------------------------------------------------------------
S201DBA: Collects RDBMS Information
-------------------------------------------------------------------------------

配置完成後，會在當前目錄下生成output目錄和配置檔案setup.cfg（如果再次執行配置過程，會生成備份檔案setup.bak，只儲存一份備份檔案。）。
配置檔案setup.cfg是可編輯的，可以直接對其進行調整。

5）此時再使用“-L modules”選項檢視，如果模組名前有“*”號表示已經配置過。
這裡為顯示清晰，省略一部分輸出資訊。最後一行有關於“*”號的解釋
ora10g@secDB /home/oracle/RDA/rda$ ./rda.sh -L modules
Available data collection modules are:
  ACFS     Collects ASM Cluster File System Information
... ...
 *DB       Controls RDBMS Data Collection
 *DBA      Collects RDBMS Information
  DBC      Collects Database Control Information
... ...
 *FLTR     Controls Report Content Filtering
... ...
 *INST     Collects the Oracle Installation Information
... ...
 *OS       Collects the Operating System Information
... ...
  XTRA     Collects User Defined Data
A '*' before a module name indicates that its setup has been done.

6）我們使用“-vCRP OS DB DBA INST”選項執行RDA對系統進行資訊採集
ora10g@secDB /home/oracle/RDA/rda$ ./rda.sh -vCRP OS DB DBA INST

解釋一下用到的選項含義。
v選項含義：詳細顯示報告生成過程，如果不加這個選項，僅會顯示上面輸出的第一部分內容；
C選項含義：採集診斷資訊；
R選項含義：生成HTML格式的報告；
P選項還以：對生成的報告檔案打包，壓縮成zip格式。

7.獲得RDA的幫助資訊

2）獲得詳細的幫助資訊
使用“-M”選項檢視詳細的幫助文件。
內容非常詳細，這裡不做展示。
如果做進一步的查詢，這個詳細幫助文件內容是由下面rda.pod檔案格式化後生成的。
ora10g@secDB /home/oracle/RDA/rda$ ls -l ./modules/rda.pod
-r--r--r-- 1 oracle oinstall 15K Nov 23 20:37 ./modules/rda.pod

8.檢視RDA生成的報告
內容簡潔實用，查詢方便。
【RDA】使用RDA（Remote Diagnostic Agent）工具對資料庫進行健康檢查

9.小結
RDA工具對於資料庫健康檢查的意義是重大的，使用RDA可以快速準確的獲取資料庫的基本資訊（資料採集整體時間最常一般不會超過15分鐘），對於資料庫的故障亦有裨益。
RDA的強大的資料採集功能不限於本文的演示內容，建議朋友們對細節引數進行研究。

Good luck.
