Subj:   V2R5 Memory Usage...
 
From:   Frank C. Martinez IV

Hola Teradudes & dudettes,

Well, we just heard from our friendly neighborhood NCR person (Cathy Vollmer, a very nice lady) that there's a new (about 3 week old) recommendation that we upgrade the memory on our nodes from 2 gigabytes to 4 gigabytes when we go to v2r5. We were told this was a recommendation, but there are people running v2r5 with as little as 1 gigabyte/node. We also heard that if we turn off all the new features, we'd still use 15% more memory. Well, the question came up, how much "memory/node" are we currently using. I (finally) got a report using Teradata Mangler, menu option Analyze>>Resource History>>Memory Utilization, and when I finally got some results out of it (it's a painful process, even though it seems simple, and I still can't figure out why half the time, we get no rows back), it showed "Mem Free %", which varies between 2.5 and 14% during the last six months.

Great.

What does that mean? Is this free memory outside of FSG Cache, the stuff that's left for Unix? I want to see what we've been using during our month-end process, memory-wise, so that I can see how much "we have left".

How do I do that? Anyway, you're help would be greatly appreciated.

iv
