Hello all,
I usually don't use this number, since I have a lot of retries due to
changing files and so on, and I would have a huge amount of
re-transmitted files. However, I've been testing (with LTO1, but I will
do it again with LTO2) and found out that you should not set this to a
number less than the buffer size of the LTO drive. Doing so will produce
a buffer flush on the drive each time you commit the transaction in
TSM's database.
Since I was working with IBM LTO drives (64MB buffer) I determined
that 65536 was the smallest number to use. I got my best results using
TXNBYTELIMIT 131072 (128MB).

Hey Everyone!
I have been looking into tuning client and server parameters for when I
move to an AIX 5.2 TSM server at 5.2.2.5. I noticed that in an
environment with LTO2, the clients txnbytelimit should be 2097152. Is
the TSM Performance and Tuning Guide correct? Thanks!
