RE: Questions about subsystems and performance (both in general and specific to Tomcat) -- MIDRANGE-L

I'm assuming this comment was made with tongue -very- firmly in cheek!

I've often wondered at people who come to the iSeries from elsewhere and are confronted with the varied and sundry layers of job routing and control. Just running a "Hello, World" program involves lots of parts of the machine! Even if the machine is pre-configured, you've got to find out how to enter source code, how to compile; and if the compile submits to batch you get into job queues, print queues, subsystems, not to mention classes! Then you've got to actually -run- the program, which can get into library lists or qualified names!

And we haven't even touched on memory pools, and whether shared pools are better than private pools! (:

Fortunately, our machines do come pre-loaded, so you can actually -do- something as soon as it's out-of-the-box... and then try and figure out why it works!

None of this is hard once you understand the job routing on the system.
