Subject parallel webapp initialization
Date Sun, 09 Oct 2011 12:55:06 GMT
Hello mailing list.

We use a single tomcat instance (soon switching from 5.5.23 to 7.x) with 24 webapps. Each
webapp is based on spring and hibernate doing a lot of I/O during initialization.
Tomcat is often restarted which causes long downtimes.  As far as i can see the tomcat initializes
its wepapps sequentially. So despite the fact, that our tomcat-intance runs on a 8 core linux
system, tomcat seems to use a single thread to initalize the webapps.

Is there a way on tomcat 7 to make it initialize webapps in parallel?
Or is there a basic obstacle?

Thanks for your help
Alex Knöller
