Quick JVM recycle question

Hello,

Quick question on a JVM recycle / restart.  If I have a  single JVM with a single application on it.  Would recyling just the application piece accomplish the same thing as recycling the whole JVM itself?  Or does a full restart / recycle of the JVM involve other pieces as well?

Thanks

Each Java process has its own JVM.

If you have a container (like e.g. Tomcat) it can contain multiple applications that together form a single process.  Generally restarting a web application does not imply restarting the entire container, so it's a subset of restarting the entire JVM even if there is only one web application present.

If you want a complete, clean restart you should restart the JVM.

If you want a logical restart of just a part of the process, you can do a web application restart, which will solve most issues but is less complete them restarting the entire JVM.

Hope that helps,

Doug
