Networker Cluster Client Configuration
Need to configure backup of a cluster client with Oracle RAC
Can someone help to explain the following configuration steps? based on document extract Cluster Installation Guide pg 31
3. Make each virtual client within the cluster a client of the NetWorker server. For each virtual client in the cluster:
a. Create a new client.
b. For the Name attribute, type the name of the NetWorker server.
c. For the Remote Access attribute, add entries for each physical client within the cluster.
For example: root@clus_phys1
d. For the Group attribute, select a group.
Why create a Virtual Client using Networker Server name instead of Virtual Client Name?
In Oracle backup script nsrnmo script will use NSR_Client of virtual host name instead.
Maybe I am new to NSR, but i read this cluster admin guide very confusing since it tried to include Networker Server in Cluster setup.

I didn't check docs, but it is typo in that case. If you use vip with RAC, use that one for NSR client and for NSR_CLIENT in RMAN script (and you can allocate channels towards different RAC nodes).
What got my attention a bit is that you mention nsrnmo - that backup script belongs to NMO module which is obsolete and you should use NMDA module instead.

completed the setup with NMDA
in general
1) link $ORACLE_HOME/lib/libobk.so -> /usr/lib/libnsrora.so
2) edit configuration file for $ORCLE_HOME and optional /nsr/apps/config/nmda_oracle.cfg
3) saveset input RMAN://
4) access *@*
or can follow document
5) backup command nsrdasv -z /nsr/apps/config/nmda_oracle.cfg
I think the most important part is working with DBA to set the rman scripts, since in RAC, the hostname, IP, connecting string, and instances needs to be very clear with sysadmin and DBA.
Networker point to the
so which every physical node with active instance _1 will be backup. DBA said _2 same so no need backup.
auto backup control file is enabled and the control file directory is backup separately
created the physical nodes clients with SKIP as documentation but dunno what is the effect or it..
I hope networker has a better documentation since they try to include all database in each section configuration instead of separate by oracle, db2, etc..
