We have found success using: txnbytelimit 2097152 *Use for LTO, DLT and 9940 drives.
We use txnbytelimit 25600 * Use for 9840 and 3590 Paul van Dongen <[EMAIL PROTECTED]> wrote: 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).

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?
