RMAN server integration with Netbackup 7.1.0.3

[mudasir_shah]

Hi All,

I have a customer who has Multiple databases running on different hosts.

They have a seperate RMAN server where from they are able to take database backups on disks, even though the databases are hosted on different physical hosts.

I tried to take the backup onto tapes using netbackp when initiated from RMAN server, but they fail with below errors.

Need help if someone has configured RMAN server with Netbackup

Server Status:  Communication with the server has not been initiated or the server status has not been retrieved

The above error says that the client is trying to connect to the NBU master and is not getting any reponse.

2 things to check:

1. Forward and reverse hostname lookup between client and master server. 
   Master must be able to resolve Client's IP address to the exact same hostname that is in Client tab of Oracle policy.
   Check connectivity from client to master with this command on client:
   bpclntcmd -pn
   Check that client resolves own hostname with same name as in the Oracle policy:
   bpclntcmd -self
   You can use bpclntcmd to verify forward and reverse lookup from master and client side.  See http://www.symantec.com/docs/TECH50198 and http://www.symantec.com/docs/TECH141117  
2. Port connectivity between client and master. 
   Check that port 1556 is open in both directions between server and client.
   Check that Windows firewall is disabled on Oracle client.

Not sure if you know about the NBU for Oracle Guide? http://www.symantec.com/docs/DOC3672

Look at the Toubleshooting section and ensure that all of the following logs exist:

On master: bprd (restart NBU for log to take effect)
On media server: bptm and bpbrm
On client: bpcd and dbclient

We will need logs to troubleshoot if failure is still seen after checking above 2 points.

Also check the size of nblog.conf file on client machine .

if its 0 kb or corrupt then also backup will fail.
