This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Hi all, I am facing a problem of slow server response ,so i would like to know certain things. 1> How to calculate the maximum number of sessions that the server (Tomcat3.2.2) can handle? 2>What is the minimum configuration of a system (RAM,Virtual Memory,etc... )for handling max users as ststed in question 1? 3> What are the maximum simultaounus connections allowed by tomcat3.2.2(databse-MySql)? 3> How to do clustering with Tomcat3.2.2? Thanks Sachin.
You're making the assumption that various internal components to Tomcat are maintained in fixed-size tables. I don't know that that's a valid assumption - most of the Java collection classes allow for open-ended collections, so the only true upper limit is the memory space on your computer. If you're encountering performance issues, the thing to do is break out the monitoring tools. Are you running 100% CPU? Heavy paging? lots of I/O to files and/or databases? Network traffic? Also, try and profile where the most heavily-used code is. Sometimes an algorithm change can make all the difference. If it's clustering you want, you'd probably be better off with a commercial appserver such as WebLogic. Tomcat's a reference platform, and the focus is more on developing next-generation technology than it is on "heavy lifting". [ February 22, 2002: Message edited by: Tim Holloway ]
