SCO

Hi

How to increase maximum number of open file in "sco xenix binary" running in "sco unix openserver 5.0.7" ?
I have changed "NOFILES" kernel parameter to 512, but xenix binray can't open more than 60.

tnx

I didn't see anything within the 5.0.7 documentation. Does your program run on earlier releases, and if so which ones?
Also, what is the contents of /etc/conf/cf.d/stune and mtune?

sco openserver 5.0.7

I don't see NOFILES in stune, are you sure you saved the changes and re-linked the kernel.

Yes, I'm sure. but I forget to put this here.
I can increase sco unix file limitation, but it does not effect on running xenix binary.
