Re: Calculating table sizes, index pages, extents

} [...intro deleted...] } entsize = (keysize * pctuniq) + 4 } } But in the examples (on page 10-17), they add 8, not 4, to get } entsize. } } 2. Earlier in the section (page 10-12), they define } } pageuse = pagesize - 28 } } Since pagesize is normally 2048, that means pageuse should be 2020. } But in the examples on page 10-17, they have pageuse = 2016. The } previous two examples in the section did have pageuse = 2020. } } Anyone know what's going here? Thanks for any help. } [...sig deleted...] IMHO, those are typos. I guess they fixed that in the newer release by not including that section at all. There may well be a script already written that does what you're trying to do. I have one in the archives that will calculate extent sizes, it's called /pub/informix/pub/extentsize. I just bourne-shell coded the formulas in the tutorial from chapter 10.
