Thanks for writing it up. The parameters should be in the same place for any SCO OpenServer release. > Solution > ---------- > NOTICE: It seems that you must edit the mtune, stune and config.h manually > to get SCO to use these values!

You don't have to edit it at all; it's re-generated from mtune, stune and other items. stune contains only those parameters which have been changed from defaults, so it's natural that you would have to add to it (except see below). In general, you shouldn't edit mtune and stune at all. Kernel parameters are normally tuned with configure(ADM) on OpenServer, but some of the changes you want to make aren't supported by that, so use idtune(ADM). Something like: cd /etc/conf/cf.d ../bin/idtune SEMMNI 2048 -max 8192 ../bin/idtune SEMMNS 2048 -max 8192 ../bin/idtune SEMMAP 2048 -max 8192 ../bin/idtune SHMMAX 671088640 ./link_unix -y I think those lines summarize what you changed, in a reasonably easy-to-use form. >Bela<
