Re: Getting a pulse for Ruby On Rails on i

From what I understand, you'll want to load Java 7 if you have that available to you. Java 7 includes the "InvokeDynamic" enhancement that helps improve performance of dynamic method dispatch in JVM, and it really helps performance of dynamic scripting languages like JRuby, Rhino, and Jython.

Well, using jRuby and JDBC to connect is "native" enough for me and easily keeps up with the Rails community changes. It is also the fastest MRI implementation since it will compile down to machine code with JIT compiling (as far as I understand Java on i).

Plenty of comparisons of JRuby and MRI on the web but here is recent one:

And another recent article with mention of AOT:
http://www.infoq.com/articles/state-of-jruby

The guys developing JRuby continue to improve the performance and implement the latest Java technologies with backward compatibility. I like that combination and the flexibility that using JRuby gives me with using existing jar's and other Java code.

My hope/goal is to get RoR completely setup on IBMi in PASE, connected
"natively" to DB2 and available through an SSH session (by-passing 5250).
I am basically trying to see if IBMi could be used as a RoR server
with very little massaging so new releases of Ruby/Rails/Rake/etc
could be adopted at the same rate as other platforms.

I found this article from Scott Klement that I believe will get me
right into qp2term without going to the 5250 telnet command line
