I’d like to know if there is anyone out there that has a way to use more than 2.25gb of memory per domino instance under AIX 5.3.
We have much more than 2.25gb available and had to create 12 domino instances, just to take some advantage of the extra memory and processors. There is still more memory and processors available.
I see these notesbench reports stating they increase memory from 2gb to 8gb-16gb of memory to a single instance, and user capacity increases dramatically, is this True? If so how does one accomplish this? How do you get a single domino instance on AIX to use 16gb’s of memory as they do in notesbench reports?
An example of a notesbench with this 16gb claim on AIX is found at IBM - United States, they claim 10,000 user capacity with a single instance on 12x400 MHz CPUs and 16 GB of RAM.
We have faster, larger, newer hardware. How can we acheive the numbers notesbench obtains on lower class machines?
Subject: Anyone able to use > 2.25gb on AIX domino instance? Notesbench advertises 16gb.
i’m no expert at all at this, just adding my 2 cents… (carefully listend to what Daniel Nashed told some time ago:)
Domino on AIX is still a 32bit program. AIX OS is 64 bit. Domino itself consists of more than one process (servertask, agentmanger, …) and all tasks but servertaks can have more than one instance. So since AIX is 64 bit each of these processes can adress up to 4 gb (without having it to share with others and OS like in 32 bit OS).
But on the other side there’s shared memory which domino makes heavy use of and that’s limited in AIX to ~2.25gb. (similar limits in linux and other os).
but tasks like http will for shure benefit from extra memory, so will others (but i’m not shure to which extent). and i really doubt consumed memory will not go up higher then 2.25, maybe you just didn’t have enough concurrent users? or there are other limits that are reached before…
the link to the benchmark doesn’t tell anything about mem-consumption.
