I cannot address load balancing or the 64-bit JVM, but I have had very good performance and stability (knock on wood) with mid-tier 7.1.00.002 on Win2K3 Enterprise R2 x64 using the 32-bit Tomcat 5.5.26 (app server AND web server) on top of the 32-bit JDK 1.5.0_14. I give the JVM 1536 mb min and max and a thread stack size of 3000, and I see it using about 900 mb max. In our environment I have never seen it go over a gig, even when pre-fetching the ITSM 7 applications, but it sounds like you will have more load in terms of concurrent users. Our mid-tier is just serving 280 support staff users (55 licenses) using the Service Desk in ITSM 7; the customers hit a Kinetic Request web on the same server which runs on its own instance of Tomcat 5.5.20 (32-bit). Hardware is an HP DL380 G5 with two quad-core Xeons and 12 gb RAM, and it's just loafing. BTW, the AR Server is also on Win2K3 Enterprise x64 (not R2, DL385, two dual-core Opterons) using the 32-bit JVM, with memory usage usually 700 mb but it peaks to over 1,290 mb during a prefetch.

The reason why they do not support this is because their engineer's have not completed their testing Mid-Tier 7.1.0 with a 64-bit JVM. They did say that some of their customers are running this configuration anyway and some are not running into any issues but of course could not give me any people to talk too nor any details. This is not good because the first time around I talked to Remedy Support and they assured me that they supported 64-bit OS's and that the server configuration below would handle what we want to accomplish so, confidently I ordered the servers. Now, to my surprise, I caught a sub-clause in their compatibility matrix that said they do not support the 64-bit JVM. This is bad news. I would like to know if there is anyone out there that has this setup (below) or something like it, and I would like to know, if any, what bugs have you experienced with running Mid-Tier over a 64-bit JVM? We plan to run 2 load balanced Mid-Tier servers each with Quad Xeon Intel based processors with 16GB of RAM using Windows 2003 64-bit as the OS and Tomcat as the JVM. We can only use Windows server so UNIX and Solaris are out of the question. We plan to deploy the Mid-Tier to out customer base as part of a front-end customer support website where customers can submit and update their own tickets. We plan to scale the aforementioned server configuration out to about 20,000 customers. Will the 2 Web Servers support that type of environment? Also, with that many customers to be supported could those 2 servers also handle another 100 licensed Support Staff? Are their any other options? Thanks. __Platinum Sponsor: www.rmsportal.com ARSlist: "Where the Answers Are" html___ _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org Platinum Sponsor: www.rmsportal.com ARSlist: "Where the Answers Are"
