We are in the process of evaluating a switch to mainframe (z9, in this case)
from a distributed architecture for a 3-tier java app. I am interested in
your experiences in doing something like this.
I've read some of the whitepapers and promo from vendors, but I am
interested in hearing more about how things have worked - or didn't - in
real-life.
With that in mind, I would appreciate hearing about your experiences - good,
bad, or indifferent. Obviously, you can respond to the message here. I've
also got a blog you can post an anonymous comment to, or just email me at

Some of my questions are:
* Was the performance as good as promised?
* Were there quirks with using the ibm jdk compared to Sun's?
* Did you have problems with security folks in your organization since
you were now consolidating the database and appservers on the same physical
machine?
* What ended up taking longer time than expected? What were you
disappointed in?
* Were the savings from such a consolidation warranted?
* Was it hard to overcome resistance to "back to mainframe" from the
distributed-thinkers?
Thanks for your time.
