Got a user doing TDP for Domino backups...................
The following is a snippet from her DOMISCH.LOG

Waiting for TSM server......
We are wondering, why the "Waiting" messges ? What is it waiting for ?
The TSM server is 5.1.1 on AIX 4.3. It is dedicated to TSM. I checked and
nothing was running at this time. No other sessions were active.
FWIW, these backups go DIRECTLY to 3590E1A FC SAN attached tapes. The
client connection is a GIG-e card on a private internal subnet.
They are still running NT 4.0. I realize this is an issue when it comes to
the TCPIP settings/limitations of this platform.
Any performance options I can tweak on the server or client side?
Here are my current server options:
