Re: After OS upgrade, can't run database engine
I had the same problem, utiill I rebuilt the kernel as follows;
cd /etc/conf/bin
./idtune -f HCPULIM 0x7FFFFFFF
./idtune -f SCPULIM 0x7FFFFFFF
./idtune -f HFSZLIM 0x7FFFFFFF
./idtune -f SFSZLIM 0x7FFFFFFF
./idtune -f HDATLIM 0x7FFFFFFF
./idtune -f SDATLIM 0x7FFFFFFF
./idtune -f HSTKLIM 0x7FFFFFFF
./idtune -f SSTKLIM 0x7FFFFFFF
./idtune -f HCORLIM 0x7FFFFFFF
./idtune -f SCORLIM 0x7FFFFFFF
./idtune -f HFNOLIM 0x00000800
./idtune -f SFNOLIM 0x00000800
./idtune -f HVMMLIM 0x7FFFFFFF
./idtune -f SVMMLIM 0x7FFFFFFF
./idbuild -B
reboot and your informix engine should now work ok
