Hi,
OK, some things to check.
First, ensure that the networking is properly set all the way from client to server. By that I mean,
- All speeds must match - under no circumstances allow auto negotiation.
- Everything should be full duplex all the way through.
- Ensure that the "NET_BUFFER_SZ" variable matches your DB requirements.
A little by the way of explanation, all your network interfaces all the way through should be set to the same speed - for arguments sake - 100Mb Full Duplex - this includes switches.
There are a lot of available settings to configure the Client and the Server communications in Netbackup, also your version is later than the version I'm running here. I'm assuming that you will have support on a version as new as that. So I'd be tempted to check the Symantec site - the support there tends to be quite good.
Anyway, let me know how you get on.
Regards
Dave
