在 Linux 上安装用于 Oracle 数据库备份的 NMDA 包括两个步骤。   

 

  • 使用 RPM 安装软件
  • 将 NMDA oracle 库与 Oracle 链接  

 

提醒：请始终参阅最新版本的 NetWorker Module for Databases 和 Application 安装指南，以获得最新信息。 

 

  1. 以 root 用户身份发出 RPM 命令并确保 NetWorker lgtoclnt和扩展客户端软件包 lgtoxtdclnt 安装在 Oracle 主机上。  
    rpm -qa |grep -i lgt
lgtoclnt-19.14.0.0-1.x86_64
lgtoxtdclnt-19.14.0.0-1.x86_64
  2. 验证 NetWorker nsrexecd 后台进程是否正在运行，如果未启动，则启动它。 
    [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. 解压缩并解压以前下载的 NMDA tar 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 安装程序安装 NMDA 软件。 
    [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. 成为 Oracle 用户（拥有 $ORACLE_HOME 目录），并创建指向 NMDA 库的符号链接。
    su - oracle
    cd $ORACLE_HOME/lib
    ln -s /usr/lib/libnsrora.so  libobk.so

     8.验证您可以使用新的 NMDA 库，通过连接到 RMAN 并运行一个简单的脚本。

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