如何在 Linux 上安裝適用於 Oracle 的資料庫和應用程式 NetWorker 模組 （NMDA）

在 Linux 上安裝 NMDA 以進行 Oracle 資料庫備份包含兩個步驟。   

• 使用 RPM 安裝軟體
• 連結 NMDA Oracle 程式庫與 Oracle  

1. 以根使用者身分發出 RPM 命令，並確定 NetWorker lgtoclnt和延伸用戶端套件 lgtoxtdclnt 安裝在 Oracle 主機上。 

   rpm -qa |grep -i lgt
   lgtoclnt-19.14.0.0-1.x86_64
   lgtoxtdclnt-19.14.0.0-1.x86_64
   

2. 確認 NetWorker nsrexecd 背景程序正在執行中，如果沒有啟動，請將其啟動。

   [root@nmda19-1 nsr]# ps -ef |grep -i nsr
   
   [root@nmda19-1 nsr]# systemctl start networker
   
   [root@nmda19-1 nsr]# ps -ef |grep -i nsr
   root      434734       1  1 15:59 ?        00:00:00 /usr/sbin/nsrexecd
   [root@nmda19-1 nsr]#

3. 解壓縮並解壓縮之前下載的 NMDA 焦油球。

   [root@nmda19-1 19.4]# gunzip nmda19401_linux_x86_64.tar.gz
   [root@nmda19-1 19.4]# ls
   nmda19401_linux_x86_64.tar
   [root@nmda19-1 19.4]# tar -xvf nmda19401_linux_x86_64.tar
   LGTO_METAFILE_linux86w_nmda.mf
   lgtonmda-19.4.0.1-1.x86_64.rpm
   sd_products.res
   [root@nmda19-1 19.4]#
   

4. 使用 RPM 安裝程式安裝 NMDA 軟體。

   [root@nmda19-1 19.4]# rpm -ivh lgtonmda-19.4.0.1-1.x86_64.rpm
   warning: lgtonmda-19.4.0.1-1.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c5dfe03d: NOKEY

   ***  Important information for completing your NMDA installation: ***
   ---------------------------------------------------------------------
   Depending on the database or application that you want to protect
   with NMDA, there might be additional postinstall steps you have to
   perform. Refer to the NMDA installation guide for instructions.
   
   ***  Important Information for Configuring NetWorker Module backups   ***
   -------------------------------------------------------------------------
   You can now start the NMC Backup Configuration wizard to configure the backups.
   To start the wizard:
   1. In your web browser, go to the URL of the console server
      http://nmc_server_name:9000 (the default port is 9000).
   2. Log in to the console server.
   3. Select the appropriate server name, click Launch NetWorker Administration
      in the right pane to start the NetWorker Administration interface.
   4. Click the Protection button, right-click Clients in the left pane, and
      select New or New Client Wizard from the menu.
   [root@nmda19-1 19.4]#
   

5. 成為 Oracle 使用者 （擁有 $ORACLE_HOME 目錄），並創建指向 NMDA 庫的符號連結。

    su - oracle
    cd $ORACLE_HOME/lib
    ln -s /usr/lib/libnsrora.so  libobk.so

     8.驗證您可以使用新的 NMDA 庫，透過連接到 RMAN 並運行一個簡單的腳本。

export ORACLE_SID=orcl    
[oracle@nmda19-1 config]$ rman target /
