Having 20K concurrent users sending requests almost simultaneously is different from having a total of 20K users using the system sporadically.. My guess in a heavily used environment, concurrent users would amount to between 50 to 60% of the total user strenght.. mild to light usage environments the concurrent users may vary anywhere between 20 to 30% of the total user strenght.. With 4 GB of RAM if you have no complaints with 20K users, not more than 100 to 200 requests might be hitting the server concurrently.. Joe

It's a dual processor with 4GB of RAM...and we have outstanding performance. Zero complaints. -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:[EMAIL PROTECTED] On Behalf Of Nall, Roger Sent: Wednesday, August 20, 2008 1:16 PM To: [email protected] Subject: Re: Mid Tier Server Connections Pool ** Joe, If only that were the case. This has been thrown together with borrowed equipment some of which is actually running other processes besides the Mid Tier. The boxes are not on a load balancer although I tired. I have no idea how much memory is on any of the boxes. The one good thing is that at most we can only have 950 concurrent users as we are limited to that number of licenses. My guess is we would have no more then 600 concurrent connections. Thanks for the information. Roger A.

I am assuming with 7K users you have your mid-tier setup in a load balanced environment, if not that better be one monstor you have installed your mid-tier on.. I have heard in the past somewhere that its good to allocate upto about 4 MB of memory per expected concurrent user so with 7K users if about 60% of them should be using it concurrently, you are looking at a region of 16 GB upwards of total memory (all 3 boxes combined).. With memory as 'cheap' as it can go these days, I would even try to go all the way and consider all the 7K users as concurrent and build your environment so you are not short changed on memory when you actually have your users use the web.. 8 GB per machine would sound like a reasonable number.. Your max number of connection per server could be adjusted accordingly..

It is the first time we are delving into any extensive use of the Mid Tier. That being said we will be conducting training for the next month. We have a total of 7k users to train. We have a total of 3 mid tier boxes. Two are 7.1 and one is 7.0.1. My question revolves around the setting for Maximum Connections per Server in the config tool. Has anyone determined a good number for this setting? Thanks, Roger A.
