Jazz Infrastructure and RTC - Server Type/Size


Ken Creager (6542220) | asked Apr 30 '09, 6:11 p.m.
I'm trying to spec out a server(s) for the Jazz server, for using Rational Team Concert. Keeping in mind we're only interested in the Enterprise Ed. which will be coming out soon (hopefully). I found this link, which seems more like the "Minimum" requirements, but I want a system that will support thousands of users (at least several hundreds - say 500 - 1,500), not tens/hundred....

https://jazz.net/help/rational-team-concert/1.0.1/index.jsp

A couple of questions:

- anyone know if newer versions of RTC will be 64 bit?? any advantage of going with a 64 bit OS? Which OS would you recommend for most scalable?? Windows or Linux??

- I will have GIG connectivity to any server, i.e. the DB server. Any recommendations of DB choice, i.e. Oracle, SQL??

- This article, and some others I read, says using WebSphere instead of TomCat is better?? They mention easy of Administration? Is it more scalable, they also mention better performance from Websphere?

- OK, last but not least, how many CPUs, how much Memory?? Sure, I want faster CPUs, but what is the point of diminishing returns?

Hopefully someone can provide some guidance :-) I see there are installations out there right now supporting hundreds of users, so what are you experiencing??

Thanks
ken

Other folks can provide more specific information but here are a few answers:

64-bit Windows, Linux and AIX versions of the server are planned for RTC 2.0. In fact they have just appeared in the M3 milestone that we posted last week.

You might also want to check out the Rational Team Concert Version 1.0 Server Sizing Guide.

Also check out the recent blog post on scalability and scalability testing to see what we've been up to in this area. The Enterprise edition in 2.0 is intended to support greater than 250 users. In 2.0 M3, the Enterprise edition will support up to 10,000 users and we'll remove that limitation in a future build before the general availability release of 2.0.

Is there anything special needed to run 64-bit included in 2.0M3? For
example, if running on AIX that's using 64-bit kernel and using a 64-bit
JRE, will the RTC automatically run as a 64-bit application?

And, are there any thoughts on the advantage this will provide? Any
performance improvements? Better memory utilization? Or, perhaps, just
more scalable?

Thanks, Brian

Try again - this link worked for me a few seconds ago. Alternatively, go to developerworks directly and you should be able to search for the paper in the Rational area (www.ibm.com/developerworks/rational)

It works now...

For some reason for ME, when I use Firefox 3.0.10 and I login to the jazz site and IBM's SR support site, I can't seem to login to developerworks's web site. Killing the browser and starting over works...

I don't know what we have specifically noticed but I am guessing the biggest thing is the scalability especially for a big server being able to address more memory. Note also that we include 64-bit versions of bundled DB2 Workgroup Edition.
