Configuration question for 2500 simultaneous tomcat users

0 votes

My project has 5000 simultaneous users average. I have two physical servers both running an instance of Tomcat 7.0. They're behind a physical load balancer with sticky, least connections balancing. Nothing in front of the Tomcats. Port 80 to is routed to them by iptables.

Please offer some tips (or point me to them) on configuration for this amount of traffic?

A great overview, and a solid outline of the process you should follow:

That, plus profiling your application with real-world traffic to understand bottlenecks and use cases . . .

Are you experiencing any problems, or are you just interested in speculative performance tuning?

Tomcat's default configuration is quite reasonable. How many simultaneous /connections/ do you expect?

It's a little bit frustrating to configure Tomcat 8.5.8 with log4j2.

I put the following jars in $CATALINA_HOME/lib
log4j 2 core (log4j-core-2.6.2.jar)
log4j 2 api (log4j-api-2.6.2.jar)

Delete the file $CATALINA_HOME/conf/
Put the new log4j 2 config file (log4j2.xml) in $CATALINA_HOME/lib

No errors but the created catalina.out file is empty and the console layout doesn't change, What else to check or change?

Is the PEM-based certificate configuration available for both JSSE-based and APR-based connectors in Tomcat 9 at this point? The documentation says e.g. the "certificateFile" attribute is for "OpenSSL Only", and when I try to launch Tomcat using the NIO connector and a PEM-based certificate file, Tomcat says that the keystore is corrupted (even though no keystore was actually specified).

I am using tomcat version 5.5.7 in windows 7 Os. My problem is that , After I configure tomcat to use SSL , I get 'Keystore was tampered or incorrect password' error when I start tomcat.

I purchased a certificate from symantec verisign , and they verified the installation was correct and they said they cannot assist me further, as it is not their part.

I tried creating a self signed certificate like this ( ) , still I get same error.

Please help me to resolve this.
