Hi! lets do a poll here, anyone who is running IDS 7.30 on linux dual-processor machine raise his hand, by mail, pls. Peter's mail was shocking. To install or not to install IDS 7.30 with this hw, Hamlet. Regards.

I'm using IDS 7.30.UC7 on a dual CPU Dell 410 without any obvious problems. I don't recall whether I've set MULTIPROCESSOR or SINGLE_CPU_VP and so on. I am conservative, so I normally set MULTIPROCESSOR when there are multiple processors on the machine, simply to ensure that it uses appropriate locking. On my boxes, I usually set SINGLE_CPU_VP etc because I don't want any one OnLine system eating too much of my resources -- or of the other two or three OnLine systems also running on the machine. I doubt if I've done anything that would notice the problems, though. I'm logging to /dev/null, and I don't think I've run ontape. Of course, there's a bigger question: why is anyone running ontape -c to /dev/null? If you set the log device to /dev/null in $ONCONFIG, OnLine handles the log backups anyway! Maybe ontape recognizes that it is doing nothing and goes away in disgust. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v0.95 -- see http://www.perl.com/CPAN #include <disclaimer.h>
