Multi-Processing Module in TomEE

[prasadkgvs <pr...@gmail.com>]

Hi All,

Does Multi-Processing Module <https://httpd.apache.org/docs/2.4/mpm.html>  
available in Tomcat also available in TomEE? or Do we have similar feature
in TomEE? 

In our web application we have native logic (built in C & C++) and it will
be called through Java. Yet times JVM used to crash due to errors in native
logic. So with TomEE if we run our web application with single process then
application availability is at risk. So I would like to know whether it is
possible to configure TomEE for multiple processes, like we configure for
Tomcat using MPM module. 
 
Regards,
Prasad.

Tomcat/TomEE runs a single Java process and does not fork. If you're
running it using OpenJDK or Oracle JVMs, it will use thread pools backed by
native threads to handle requests with the default setup.

But TomEE/Tomcat is very different than Apache Httpd. Tomcat/TomEE run Java
EE Applications typically packaged as .WAR or .EAR files. Httpd is a
general purpose web server. While there is some overlap (yes, you can serve
files up with Tomcat/TomEE very quickly), it's best to use them for their
particular task they were designed for. Modules for httpd are in no way
compatible for Tomcat/TomEE.

If tomcat supports it tomee does...but i fear you mix tomcat and httpd.

You can start N tomee and use httpd to load balance them. Should solve your
issue.
