Unixware 2.0 Kernel Parms for 7.10 DSA?

Hi All! Got me a UW2.01 box with 48MB of RAM, and we seem to not be able to allocate more that 12MB to the shared memory instance. This is a dev system with one user (me) and the engine. No X, no nothing. The SHMVIRTSIZE is 8000, and SHMADD is (currently) set to 8192. The system initializes, but when I do an 'onmode -a 8192', the memory allocation fails. I seem to be able to 'onmode -a 1024' until the instance size hits around 12MB. I've got my parameters set to everything appropiate according to the Release Notes, but still no enchilada. So, I was hoping that someone out there in the great etheral Beyond(tm) might ALSO be running UW and 7.1 DSA, and might, perhaps, being willing to share their kernel parameters. Informix Tech Support and I tried some assorted changes, but they don't seem to be working, and they don't have any cases that seem relevant. I tried playing with SVMMLIM and HVMMLIM (which are not in the release notes), but to no avail. The only case they had close to this said to double these parameters, but not from what number to what number. I'm not sure even what these do. As some final tidbits: The error I get when I try to add more memory (or when the engine tries itself), from the log - 11:35:47 shmat: [ENOMEM][12]: out of available data space, check system MAXMEM Version 7.10UC4. Thanx one and all, Will Hartung (villy@collinscomp.com)
