Sådan installerer du NetWorker Module for Databases and Applications (NMDA) til Oracle på Linux.

Installationen af NMDA på Linux til Oracle-databasesikkerhedskopier består af to trin.   

• Installation af softwaren ved hjælp af RPM
• Sammenkædning af NMDA-orakelbiblioteket med Oracle  

1. Som rodbruger skal du udstede RPM-kommandoen og sikre, at NetWorker lgtoclntog udvidet klientpakke lgtoxtdclnt er installeret på Oracle-værten. 

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

2. Kontroller, at NetWorker nsrexecd-baggrundsprocessen kører, og start den, hvis ikke.

   [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. Udpak og udpak din tidligere downloadede NMDA tjærekugle.

   [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. Brug RPM-installationsprogrammet til at installere NMDA-softwaren.

   [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. Bliv Oracle-bruger (den bruger, der ejer $ORACLE_HOME bibliotek), og opret et symbolsk link til NMDA-biblioteket.

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

     8. Godkend, at du kan allokere en SBT-kanal ved hjælp af den nye NMDA bibliotek, ved at oprette forbindelse til RMAN og kører et simpelt script.

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