Removing non-essential services

[pazu]

I'm using JBoss (3.0.0 CVS) to deploy a simple J2EE application. To optimize memory utilization and performance, I'd like to remove all services I won't be using. Which services are essential to get a application that uses CMP2 connecting to a single database, struts, some servlets and JSP working?

Here is the list of files I'm moved out of deploy dir already:

cluster-service.xml
counter-service.xml
hsqldb-default-service.xml
jbossmq-*.xml
jms-*.xml
mail-service.xml
scheduler-service.xml
user-service.xml

The following files are still on the deploy dir:

ejb-management.jar
jboss-jdbc.rar
jboss-xa.rar
jbosscx.sar
jetty-plugin.sar
jmx-ejb-adaptor.jar
jmx-ejb-connector-server.sar
jmx-html-adaptor.sar
jmx-rmi-adaptor.sar

Can I further remove some of these files? Have I removed some important service?

It would take a whole book to explain :-)

If you aren't using hsql or messaging, I think you are
ok? The counter-service is new, I'm not sure what it
does?

You might want to check the logs for waiting messages on
services to make sure they have all been satisfied.

You probably only need one jmx-adatptor, if you
aren't using any of them you can remove the connector
as well.

These are all hot-deployable, so move them to a different
directory. If you find a problem, move it back it into
deploy.

There's been some talk on the dev-list about
providing example configurations ranging from
a minimal micro-server through to the whole
shooting match.

Maybe these will be supplied with 3.0final

A book which I suppose is being written? Good luck, guys.
