Tobi,

One thing to consider when running ASF2 is that the Teradata nodes (TPA) are tuned for Teradata. What I have seen in the past is that non-DBMS processes will tend to have contention problems with the DBMS when the DBMS is very busy. I have seen instances where arcmain processes running on TPA nodes will virtually come to a stop when the DBMS is at 100%.

My experience has been that you are better off running ASF2 and your arcamin scripts on the non-TPA nodes. This would mean connecting your tapes drives to the non-TPA nodes as well. In tests that I been involved with, the throughput is virtually identical to running on the TPA nodes and the performance is far less affected by DBMS utilization.
