[jianmin_Tan]

Dear all:

I have seven media server and one master server in my environment.I want to backup both the oracle data and archive to the netapp storage system.

I use two channel for the backup and set the parameters in the scripts.

There are some error occured  on two media server when I try to backup the oracle data.(Other five media server were worked normally.)

The error information is below.

I have check the oracle link and bp.conf but there no configuration error in them.

Can anyone give me some suggestion?

1.) Check the values in the NET_BUFFER_SIZE file value on the client and on the server side are same ?

2.) ORA-19511: Error received from media manager layer, error text:
VxBSACreateObject: Failed with error:


As per the Error ORA-19511, If you see the below link it seems that the problem is with media management software.

Are you able to backed up other data/Flat files backup on these two media Server, means Network connectivity is fine, and DNS too.

'Server Status:  failed to communicate with resource requester'

Are normal (filesystem) backups working with these two media servers?

This error message looks like a NetBackup Status 811.

Here is my own experience with status 811: https://www-secure.symantec.com/connect/forums/netbackup-655-media-server-problems#comment-3702681
