Perhaps the developers could comment on that?Yes, it seems like a Small Matter Of Programming. http://wombat.doc.ic.ac.uk/foldoc/foldoc.cgi?SMOP In seriousness, yes, it would seem a reasonable idea to calculate some of these values a bit more dynamically. I would be inclined to start with something that ran a workload, and provided static values based on how that workload went. That would require NO intervention inside the DB server; it could be accomplished simply by writing a database script. Feel free to contribute either a script or a backend "hack"... -- let name="cbbrowne" and tld="libertyrms.info" in String.concat "@" [name;tld];; <http://dev6.int.libertyrms.com/> Christopher Browne (416) 646 3304 x124 (land) ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
