I've seen this problem before.  The physical nodes need to be configured 
clients on the server, and you should add the physical node names to the remote 
access list of the client config(something like *@<node name> for each physical 
node that it can run on).

Subject: [Networker] NMDA for Oracle - Linux Cluster

Hi All;

We have a Linux cluster (2 nodes) running oracle 11.
NW 7.6 SP5 (Backup Server Solaris 10)
NMDA (NetWorker Module for DB and Apps) version 1.2

We have the error:
     nsrdasv : The NSR /client resource/ for <active_node_hostname> could not 
be located.
We have configured the backup using the virtual name as client resource (using 
the NMC Wizard).

This problem does not occur if we use the active node hostname as client 
resource (the VIP's CLI is updated as the RMAN script contains the NSR_CLIENT 
variable set)

To be High Available we obviously need to use the VIP but we get that error.
We have checked the name resolution and all aliases without success.

Does anyone has successfully configured NMDA for Oracle cluster backup?
Any idea what the problem can be related to? I might have missed something 
during the configuration/installation?

Thanks in advance.
