Note that at least on a z800 (2066), there is _no_ difference between an IFL and a CFL engine. In fact, there is nothing on the HMC profiles to state the partition is to use an IFL. You set it up as a CFL processor.
I wouldn't totally count on all vendors to say that a zAAP does not affect their pricing. The reason is that some OEM vendors are starting to use Java (ref: SAS 9.1.2) in their product. They may (or may not) decide that a company must pay extra if they have a zAAP because their product will use it. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
