Sorry, I didn't see the [UV] in the subject line! It's amazing how similar these two are at the colon prompt, yet how different underneath... -- Wendy Smoak --- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] [UV] How far can STR1 := SPACE(1000000) grow?
Thanks guys for all the responses. Can someone tell me why I'm getting a miserly 30MB on a system with 8Gb. Anyone try this on unixware or sco openserver? If you get anything different for unixware/sco, please I want to know how your system is configured.

No Wendy - you cheated and used UniData where variable space is allocated (and garbage collected) from shared memory by smm which means that you can tune this sort of thing in udtconfig. On UniVerse variable space is malloc()ed (or an equivalent) so: 1) the limits are different - probably kernel or maybe ulimit based on UNIX; and 2) there is a further issue that after you've created this large variable, you may get strange behaviour out of other code which normally works fine because you've already used up the memory available to you from the heap.

Please try the following on your server and find out how far you can go before malloc fails. On my Unixware server with 8Gb RAM, I can only go as far as 24 to 30 MB before the process fails with 'Available memory exceeded'. Running 'sar -r' at the Unix prompt shows me over 3 Gig of RAM is still free. Are there any parameters I can change to increase the limit? On my XP latop with 512MB RAM, I can run the program upto 250MB then it begins to really crawl, taking upto 15 seconds to go through the loop.

255MB on uv 10.0.8 on a sun solaris sparc "netra" w 512MB memory - it was quite fast except a few hangs ( caused by garbage collect?) until it died with Available memory exceeded, -- mats Marco Manyevere wrote: Please try the following on your server and find out how far you can go before malloc fails.
