Deleting Pre-Packaged Tomcat WebApps

  • 772

I currently work on an excruciatingly slow remote machine and on Tomcat. So, I was wondering, Tomcat comes with some pre-packaged webapps like:

docs
examples
host-manager
manager
ROOT

Now I just wanted to know, can I delete docs and examples from the webapps folder without harming the server? I would assume that the other three webapps do serve some important purpose. All in all, if I do remove them, it will save me about 2.5 minutes on average every time I start the server.

    1. You can safely remove docs, examples, host-manager and manager if you don't use them.
    2. The ROOT application is almost empty. Removing it entirely can cause some small bugs in some valves (e.g. RewriteValve), but you can replace it with an empty directory.

    You should also consider other ways to speed up Tomcat's start up. If the server is a virtual server (without physical devices), entropy gathering might be a big problem.
