一、安裝部分
Backup Exec是一款主要用於Windows平台的數據保護產品，但是它也包含了用於Linux或Unix的代理程序。要清楚你所使用的Backup Exec支持哪些Linux或Unix系統，請訪問技術支持網站上的軟件兼容性列表，以現在用戶數量最多的BE10d為例，它的兼容性列表網址是：
http://support.veritas.com/docs/278254
你可以在軟件兼容性列表中發現兩個用於Linux或Unix的代理產品，它們的兼容性不同：
Remote Agent for Linux and UNIX Servers (RALUS) Compatibility // 即RALUS，新的代理程序，收費，性能較高。
Legacy Linux/UNIX/Mac Compatibility // 傳統的代理程序，免費，性能較低，以後會被RALUS取代。
查過兼容性列表之後，如果你所使用的操作系統包括在兼容性列表之中，就可以考慮采用Backup Exec來保護你的系統。如果兼容性列表中沒有列出你所使用的系統，則可能存在兼容性問題，建議先進行測試，確認可以使用再購買。
下面將介紹RALUS的安裝（Legacy Agent現在很少有人使用，就不介紹了）
下面假定你的Media Server（安裝有Backup Exec的備份服務器）己經安裝好，並且安裝了RALUS選件。
首先，RALUS的安裝程序較大，被放在單獨的光盤中提供。如果沒有安裝光盤，也可以通過Symantec網站下載：
http://support.veritas.com/docs/279329
下載的安裝包是壓縮的，需要先解包，光盤中的安裝程序不是壓縮的，可以直接安裝。下面是我的安裝記錄（用的是BE11d RALUS安裝程序），中間加了一些解釋（紅色部分）。

二、配置部分
BE11d的Oracle Agent與以前的版本有本質的不同，它采用RMAN來備份Oracle數據庫，也支持Linux系統上的Oracle數據庫，很多用戶對它的配置還不熟悉，特別是在Linux系統上的配置，下面是我所做的一個配置實例。中文部分是我加的說明。
[root@ora10g lib]#/opt/VRTSralus/bin/AgentConfig // 安裝好RALUS之後，請使用root用戶來配置代理程序。

Do you want to use the full computer name/IP address for Oracle operations? (Y/N):n // 指定名字的好處是，避免因為計算機名字或IP地址的變化導致Recovery Catalog中的記錄信息混亂。
Do you want to use a custom port to connect to the media server during Oracle operations? (Y/N): n
// 默認的端口號是5633，建議不要改動它，除非這個端口己經被其它應用程序占用，如果這裡做出了改變，介質服務器端也要做同樣的修改。
Commit Oracle operation settings to the configuration file? (Y/N): y

安裝代理
安裝文檔
http://seer.entsupport.symantec.com/docs/282010.htm
配置agent
主要文件為ralus.cfg這裡注意配置格式，需要將media server改為BE server的hostname或者IP address，
1. From the /etc/VRTSralus/ directory, open the RALUS.CFG file using a text editor
2. To add additional media servers, add the following line:
Software\VERITAS\Backup Exec\Engine\Agents\Agent Directory List<Suffix>=<Media Server Name>
where <Suffix> is a UNIQUE identifier, 'A', 'B', 'C', '1', '2', '3', and where <Media Server Name> is the name or IP address of the Backup Exec 10.x media server.
排錯
如果不能夠成功在BE找到Linux資源，就需要排錯。
一般不能夠找到資源的問題是Linux的防火牆（建立關閉）、SElinux關閉、版本不一至。
配置oracle代理
(1) 關閉代理 agent /etc/init.d/VRTSralus.init stop
(2) cd /opt/VRTSralus/bin
(3) ./AgentConfig開始配置
關於權限配置http://seer.entsupport.symantec.com/docs/302179.htm
備份資源
這裡注意賬號的選擇，系統登陸使用oracle賬號,oracle資源使用sys賬號。

Exact Error Message
Final error: 0xe0001402 - This server name is not in the list of authentication credentials on the media server. Enter the server name and its logon account on the media server, and then retry the operation.
Details:
This error occurs when the Oracle server name is not added in Backup Exec. To add the Oracle server name, follow the steps mentioned below:
1. Open the Backup Exec console, then click on Tools > Options > Oracle.
2. Click on the Modify List button as shown in Figure 1. Add the Oracle server name and the logon account name to the media server's list of Oracle servers and authentication credentials using (1) the fully qualified domain name, (2) NetBIOS name and (3) IP address as separate entries, each using the same logon account.

啟動db控制台
從網頁進入管理：

使用sys用戶登錄
特別注意Connect as選項選擇SYSDBA
oracle
rm -rf $ORACLE_BASE/*

rm -f /usr/local/bin/coraenv /usr/local/bin/dbhome /usr/local/bin/oraenv
ORA-00119 和 ORA-00132 的解決方法
由於今天修改了測試數據庫的hostname，造成一下錯誤：
SQL> startup
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00130: invalid listener address '(ADDRESS=(PROTOCOL=TCP)(HOST=orcl)(PORT=1522))'
其實解決起來很簡單的，請查看詳情。。。。。
因為修改了主機的hostname（原來是orcl，修改後是vmware10g），所以10g的實例就沒有辦法動態注冊，那麼就沒有辦法啟動了，我的監聽配置的也是正確的：
Listening Endpoints Summary...
(DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC2)))
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=10.10.10.2)(PORT=1521)))
Services Summary...
所以呢，當你修改了主機的hostname以後，就要相應的修改數據庫的初始化參數。
-bash-3.00$ sqlplus "/ as sysdba" （先連接上數據庫）
SQL> create spfile from pfile='/export/home/oracle/1.ora';
修改pfile裡面的local_listener如下：
*.job_queue_processes=10
*.local_listener='(ADDRESS_LIST=(Address=(Protocol=tcp) (Host=vmware10g)(Port=1521)))'
*.open_cursors=300
SQL> create spfile from pfile='/export/home/oracle/1.ora';
SQL> startup
ORACLE instance started.
