How to Install NetWorker Module for Databases and Applications (NMDA) for Oracle on Linux.

The installation of NMDA on Linux for Oracle database backups is composed of two steps.   

• Installing the software using RPM
• Linking the NMDA oracle library with Oracle  

1. As the root user issue the RPM command and ensure that the NetWorker lgtoclnt, and extended client package lgtoxtdclnt are installed on the Oracle host. 

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

2. Verify that the NetWorker nsrexecd background process is running, and start it if not up.

   [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. Uncompress and extract your previously downloaded NMDA tar ball.

   [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. Using the RPM installer, install the NMDA software.

   [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. Become the Oracle user (the user which owns the $ORACLE_HOME directory), and create a symbolic link to the NMDA library.

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

     8. Validate you can allocate an SBT channel using the new NMDA library, by connecting to RMAN and running a simple script.

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