Install gc agent on client is getting 'Please specify a Unique Oracle Base directory'(redhat 5.3_x8

在使用遠端安裝gc clinet的agent時,執行agentDownload.linux命令,遇到了"Please specify a Unique Oracle Base directory"的錯誤,本文描述瞭解決這個問題的方法和步驟.

主要的方法是: 修改/etc/oraInst.loc檔案,將本次agent安裝的日誌存放在一個新的目錄中(本次為/oracle/oraInventory2)

另外的一個方法: 備份舊的inventory內容,清空inventory 目錄,完成安裝後,恢復回來.

二. 問題分析與解決

嘗試了幾次從遠端安裝agent都失敗,都報"Please specify a Unique Oracle Base directory"錯誤.

在網站找到一個朋友的提示,可能是inventory的問題,嘗試修改inventory,獲得的安裝成功.

兩個修改inventory 的方法:

方法一. 使用root使用者身份,修改/etc/oraInst.loc 檔案,

#vi /etc/oraInst.loc

Modify:

inventory_loc=/oracle/oraInventory

inst_group=oinstall

To:

inventory_loc=/oracle/oraInventory2

inst_group=oinstall

方法二. 備份inventory目錄後,清空該目錄,安裝完成後,再恢復回去.

$tar -cvf /setup/oraInventory_old.tar /oracle/oraInventory

$rm -rf /oracle/oraInventory/*

...

然後執行安裝

Gc client:

$rm -rf /oracle/OracleHomes/agent10g/*

$cd /oracle/OracleHomes/agent10g

$wget

$chmod u+x agentDownload.linux

$export ORACLE_HOME=/oracle/OracleHomes/agent10g

$./agentDownload.linux -b /oracle/OracleHomes -m ocmdb2 -r 4889

……

#Root script to run

/oracle/OracleHomes/agent10g/root.sh

To execute the configuration scripts:

1. Open a terminal window

2. Log in as "root"

3. Run the scripts

開啟一個視窗,使用root身份,執行/oracle/OracleHomes/agent10g/root.sh

$cd /oracle/OracleHomes/agent10g/bin

$./emctl secure agent

[oracle@ocmdb1 bin]$ ./emctl secure agent

Oracle Enterprise Manager 10g Release 5 Grid Control 10.2.0.5.0.

Agent successfully stopped... Done.

Securing agent... Started.

Enter Agent Registration Password :

到此安裝完成.

三 . 問題總結:

透過以上的操作,我們基本上明白了,錯誤之源在於oraInventory目錄的設定,只需要修改/etc/oraInst.loc檔案,將本次agent安裝的日誌存放在一個新的目錄中(本次為/oracle/oraInventory2),與原來安裝DB的inventory分開,就可以避免報"Please specify a Unique Oracle Base directory"錯誤.這個問題在redhat 5.3_x86上遇到,在redhat5.3 x86_64位上好像沒有遇到,也許是oracle的安裝程式指令碼存在一些bug.
