HI all: I recently heard about the possibility of upgrade de query optimizer. I 've got ON-LINE 5.0 and at Informix Seminary, It was listened taht by upgradin only the query optimizer, somes exposed queries at the seminary, had down its times from 30 minutes to seconds. I want to know, If anyone heard something about this points. I would apreciate very much information about this. We have a system with deal with some millions of rows per table and we need improve perfomance in queries because of the time processing that is critical for us. We can't, for the moment, migrate to a new Informix's ON-Line version. Thanks in Advance. @@@@ @@@@@@@ Mauro G. Pisano @@@ @@@ @@@ @ Analista Programador. @@@ @ @ @@@@@@@ Direcc.
