Re: Hardware requirements for Tomcat
hai, Model it and measure. Though, be critical of your measurements, too. I've been involved in a case where the developers were claiming that an application running on a two-machine cluster with 2GB JVM heaps on each machine did require at least 4GB heap/machine. After proper investigation, a memory leak in the application server (not Tomcat) was found, and eventually corrected by the server vendor. After the correction, the JVM heaps were lowered to 1GB/machine, and most possibly could be lowered even further. what software that can test memory leak ? -- TIA, Andy Susanto,S.Kom == for better search http://www.slashmysearch.com/earn/id/24828 HP : 081513039998 On Sun, Oct 12, 2008 at 3:09 PM, Juha Laiho [EMAIL PROTECTED] wrote: Arun M wrote: I need to know the hardware requirements in CentOS for hosting a website which have 1000 concurrent users. I am using Tomcat 5.5, Mysql 5.1 and Java1.5. That depends a lot more on your application and usage patterns than on the OS/application server/database server. We are planning to host two servers one for application server and other for database server. That's a good basic division.

So, in as early stage as possible, create some kind of test setup where you can see effects of different work loads on your servers. Extrapolate from results, and as you gain knowledge of the application and workload, rerun your tests to get better estimates. -- ..Juha - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: How to change default port 8080 in TomCat ?
you can change in server.xml. that file you can find in tomcat_install_dir/conf/catalina on section Connector port=8080 became Connector port=9955 -- Regards, Andy Susanto == for better search http://www.slashmysearch.com/earn/id/24828 HP : 081513039998 On Wed, Apr 9, 2008 at 5:33 AM, Ben Stover [EMAIL PROTECTED] wrote: Hi, If I want to change the default port 8080 where TomCat is listening to another port (e.g. 9955) where can I do this?

I am using the following: MySql: 5.0.22 tomcat : 5.5.X Now the problem is when I run the application, it can't get the connnection from the connection pool. I tried everything like dumping all the waiting threads, killing all the tomcat processes but nothing seems to work. I can't revert back the results. I want to run the application as I was before. Any suggestions for closing all the connections (if open at all) or anything else so that I can run mu application as earlier.

It's almost certainly application-related. or is there anyone that have a problem like me ? I think most of us have had a problem like that at one time or another. Profile your application when it runs slowly, and see what's causing the slowdown. Remember to profile your database as well. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
