Tomcat on SWITCHengines
Tomcat on SWITCHengines
When using Tomcat on SWITCHengines, starting it can take quite some time. Tomcat internally uses the "SecureRandom" random generator.
2 approaches to mitigate that problem:
- Package haveged. With the installation of the ubuntu package "haveged" the problem is definitely solved.
- Urandom. With the option
"-Djava.security.egd=file:/dev/./urandom"
the starting behaviour is improved. It's still slow, but Tomcat starts reliably.
