    How to prevent IDS server from taking the whole CPU

    Hi, I'm running a IDS on a Windows 2000 machine with just one CPU. Sometimes I found that oninit took 95+% CPU and caused other application failure. Is there a way to configure Informix so that it would not take too much CPU resource. Thanks Peng

    Write a command script to be run by SQL Editor

    Sorry, Shriyan. Maybe I didn't make the question clear. What I wanted actually is how can I pass in the password without having to manually input them at Runtime. I just wanted to run a script to update the database at background without any interruption. Although I could use the using...

    Can I use "Load" statement in E/SQL

    Thanks a lot. But what I was trying to do is that we need a upload/load program which will do the upload/load when a certain condition happens and it would do the upload/load many times a day. I guess HPL won't meet the requirement. The program for now is using a cursor to insert row by row...
