Solaris memory management

I am trying to find out what the limit is on contiguous memory in Solaris. Can I grab one segment of 20G, or will Solaris break the segment down into smaller pieces ? For example, if I run onstat -g seg, can I have one segment of 20G, or is this not possible ? I am using Solaris 9 and IDS 7.31 FD3 ...... 64bit Dirk Moolman Database and Unix Administrator MXGROUP "People demand freedom of speech as a compensation for the freedom of thought which they seldom use." sending to informix-list

Hi, On UNIX systems INFORMIX reserves memory in blocks( this is 8k each one). Your 20Gg of Memory are 20 Gb / 8Kb of contigous blocks. If you see in your onstat -g seg one virtual value, there are one contiguos Virtual segment. Otherwise, remember that INFORMIX manage a RESIDENT portion, that is other memory segment, so at the end the minimun segments in INFORMIX are one resident and one virtual. regards.
