TK, did you work on the issues with Sun Support? Or did you just rely on free 
resources on mailing list? Thanks. Peter

growth with concurrent updates) - which are hitting us very hard (e.g. 
estimated query costs growing into the hundreds of thousands and some in the 
20+ million within days with just a dozen live rows in those tables, even when 
after creating otherwise-unnecessary indices for direct access), plus other 
issues where the compress table stored proc isn't reclaiming the dead space 
unless we really bring the application server down, we have to abandon Derby, 
and I just wanted to thank you all for your support.
