Look like the best deploying option I ever
found for Rails, GREAT!
The combination of Rails 2.0.2 (stable), JRuby 1.1 RC2, the Glassfish gem, and JDK 1.6 is not only breaking down enterprise barriers but speeding
up apps all over the place
leading the way to simple, scalable, no-hassle hosting for Ruby
web applications.
No mongrel packs to manage, no cluster of apps to monitor, and no WAR file relics to slow you down. "glassfish_rails myapp" and you're done; it's true one-step
deployment.
had no reliability and performance issues with
Glassfish
money is on JRuby (and Glassfish) for the long haul; if you haven't checked
out Glassfish yet, you're doing yourself a disservice!
Rails Monitoring ?
! Basic Monitoring
- jinfo – Prints Java System properties and VM CLI flags
- jmap – Shared object memory map or heap memory details
- jstack – Stack traces of Java threads
- jstat – Performance statistics on class, JIT compiler, GC
! Deep Dive
- jconsole / VisualVM
- NewRelic
- Five Runs
