New comer to DB2

[DT]

Any website or book for studing IBM DB2 since I'm new to it and no database
experience.
Thank you for your reply.

Try DB2 for Dummies - It starts at the beginning and includes many examples

But to be fair it really is difficult to write a good book on performance
tuning. There
are just so many variables that you can't really generalize except by just
describing the low level concepts and tools. You really do need an
experienced expert who can integrate those things with the actual
implementation. I'm not a DB2 person or even a performance person,
but I've worked on engagements where performance is an issue (and
when is it not? :) and in every case there has not been a "cookbook" way
of dealing with the performance issues. It's always been a process of
trying this, trying that, do some head scratching, and so on. In many
cases you need to come up with a really innovative solution to address
the performance, and again you really can't generalize such solutions.

A lot of the things that the original poster was talking about are
addressable with the existing DB2 tools, or with third party tools.
For example there is a freeware tool called, as I recall, iotest, which
will exercise your drives very extensively and thus will pinpoint
problems with the raw drive I/O. DB2 v8 has explain as well
as a tuning wizard.

And there is a DB2/SAP book, look at amazon. I'm not familiar with
it but amazon does have sample pages, and the sample index page
does have entries regarding performance.
