What is the max connection Pool setting would be ideal if I am expecting around 300 concurrent users and 10,000 overall users are going to hit the websphere application?
I have 10 GB of RAM & Dual Processor.

What would be ideal JVM heap size?

What should be the DB2 settings such as #of Max Agents settings?

Thanks.

If there are 300 concurrent users, 300 max connections would be a choice. But it can be fine tuned, considering the no. of client requests that can be processed at any given time(a value in plugin). The knowledge on the application and its usuage will also help to bring down the value. As all the users who come to the site won't make transactions, this is possible. In a typical case, 128 would be an opt value. Based on trail&error, this can be increased.



For JVMheap sizes, check your appservers recommended values. Those are the optimized values for better performace. If you face pblms with those values, increase the Xms and Xss values.
