Hi
Check duplexing on the NIC on the Oracle server and the switch port for the 
server.

It might be set to half duplex. Try setting both to full  Dup.

Subject: [Networker] Large Oracle database failing on one channel.

I'm running networker 7.6.3.5 and NMDA 1.2.  We have a large database, probably 
around 3TB or better.  It will complete mostly, but error out on a single 
channel for some files.  We've reduced the channels down to 2 and it helped 
some, but we are still seeing database files failing with the below errors.  
Any thoughts?
