Eval,
Some of my questions are:
* Was the performance as good as promised?
Depends on the application. Heavy I/O favors the System z. YMMV
* Were there quirks with using the ibm jdk compared to Sun's?
None that I am aware of. More problems with different levels of Java.
* Did you have problems with security folks in your organization
since
you were now consolidating the database and appservers on the same
physical
machine?
Security folks do their job well; However, application architecture
should not be one of them.
* What ended up taking longer time than expected? What were you
disappointed in?
Uncertified combinations.
* Were the savings from such a consolidation warranted?
Silly question. $$$ are behind most consolidations.
* Was it hard to overcome resistance to "back to mainframe" from the
distributed-thinkers?
Closed-minded thinkers are the same regardless of platform.
By the way, are you thinking z/OS or Linux on System z?
And, lest I mislead you, I answered the above questions based on the
experiences of others. But I'll bet dollars to donuts, most respondents
would reply similarly.
