Hardware: VAXstation 3200 OS: Ultrix 3.1 How do I go about increasing the allowed datasize for a user? I reconfigured the kernel with dmmin and dmmax changed to allow a large data segment, but those changes did not reveal themselves to the C shell limits. This user needs a virtual space of about 128MB, but is presently limited to about 21MB. Is it possible to get a data segment that large, and what do I need to change in order to allow it? Thanks for all replies in advance, -John

Did you rebuild the kernel after making the change in the configuration file? Did you reboot using the new kernel? What limits does limit show? Changing dmmax should be enough if you used a legal value. > This user needs a virtual space of about 128MB, but is presently > limited to about 21MB.

You should be able to use dmmin = 32 and dmmax = 8192. Now the real question is whether you have enough page/swap space to back that much virtual memory? Using a couple of RD54 just for page/swap will get you enough if you're using DEC disks. 3rd party stuff would make it easier. > > Thanks for all replies in advance, You're welcome. > -John -- Alan Rollow alan@nabeth.cxn.dec.com
