Come installare NetWorker Module for Databases and Applications (NMDA) per Oracle su Linux.

L'installazione di NMDA su Linux per i backup del database Oracle è costituita da due passaggi.   

• Installazione del software tramite RPM
• Collegamento della libreria oracle NMDA con Oracle  

1. In qualità di utente root, eseguire il comando RPM e assicurarsi che il lgtoclnte il pacchetto client esteso lgtoxtdclnt sono installati sull'host Oracle. 

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

2. Verificare che il processo in background nsrexecd di NetWorker sia in esecuzione e, se non è attivo, avviarlo.

   [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. Decomprimere ed estrarre la tarball NMDA scaricata in precedenza.

   [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. Utilizzando il programma di installazione RPM, installare il software NMDA.

   [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. Diventa l'utente Oracle (l'utente proprietario di $ORACLE_HOME e creare un link simbolico alla libreria NMDA.

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

     8. Convalidare la possibilità di allocare un canale SBT utilizzando il nuovo NMDA libreria, connettendosi a RMAN e l'esecuzione di un semplice script.

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