| TSM: ANS1809W A session with the TSM server has been disconnected |

Problem:
While backing up large files over slow links, the following message may appear:
ANS1809W A session with the TSM server has been disconnected. An attempt will be made to reestablish the connection.

Solution:
First of all, this is a warning message which simply indicates that the client will set up a new connection and resume the operation in a few moments. It does affect the overall throughput though, so if it happens frequently you may want to do some tuning. This is what IBM says:
Keep in mind the TSM concept of Producer and Consumer sessions, where the former is the "manager" who mostly stands around, and the latter is the "worker", busy transferring data. The Producer session is expected to time out during long data transfers, as we've previously explored on the List, and explained by IBM in Technote 1161949. Having a long Idletimeout value reduces the occurrences of these.
How to adjust the timeout values? On your TSM server, start DSMADMC (found in your baclient directory) and use the following commands:
SETOPT COMMTIMEOUT 60
SETOPT IDLETIMEOUT 15
The values shown are default values, you may wish to increase them slightly. COMMTIMEOUT is in seconds, IDLETIMEOUT is in minutes.
