The key is "will be". So be patient. Alternative is list archives - performance considerations were many times discussed. Third option might be DB2 docs. Basic DB2 performance tuning looks just like TSM DB tuning but is having more switches and levers ,-) On the end internal TSM DB is just the DB2 code at version 1 or 2 with some functionality stripped out. Single DB instance, unknown number of tablespaces (with no individual control), single bufferpool for tables and indexes, etc. The only curious thing (for me) is that DB2 does have a tablespace limit of 64 GB if 4kB pagesize is used. And even if TSM uses separate tablespaces for BACKUPS, CONTENTS and AS.Segments tables it is unknown what can happen if any table reaches this limit (and is this a limit for TSM). On the list I've seen client, driver, TDP developers, support people but not yet server developer (or I missed him/her) to reveal the mistery :) So if you need a book right now just ask a DB2 admin for some hints or visit DB2 docs site and read few chapters there.
