Hi,
I'm not sure if you are aware, but there is already a tool to do this, based on the p6spy jdbc driver. It's available under the Apache license too.
I believe the only thing it doesn't do is the analysis of the data to suggest indices.

I've only glanced at the tool, not used it.
Even if that tool is not what you want, it's probably better to extend the p6spy driver to do what you want - as it would be applicable across all environments that use jdbc
Cheers,
Charles.

Hi,
I would like to know where the best place would be to hook into ojb a class
which logs all sql statements sent to the DB.
My idea is to analyze the from and where clause and log into a database
table the actual statements used in a live system. I then would like to
write a tool which analyzes this table and suggests the "best" indices to
create on the database.
To make sure I really catch all statements I would like to directly hook
into ojb. Also, this could then easily be re-used.
We thought about a trace but the amount of data just seems to big.
Any ideas / suggestions ?
Thanks, Stefan Schlösser
