Re: OK - a really stupid question.

Systems Support Analyst County of Ventura, CA 805-662-6731 [EMAIL PROTECTED] [EMAIL PROTECTED] 5/22/2007 7:36 AM Hi, John. No such thing as a stupid question, imhostupid answers, maybe;-) McKown, John wrote: Yes, I know this will be a stupid question. But I will ask anyway because I have no fear (or was that no sense?). A zAAP engine is used by z/OS to run Java code. The only reason for such an engine was because of the CPU demands of Java and the fact that adding the required CPU power using a general purpose engine would drive up the other software costs. That is, a zAAP engine is a marketing ploy to sell Java (an maybe some other Java-dependant software such as WAS). It is not a solution to a technical problem with Java on z/OS. Therefore, there is no need/reason for Linux on System z to ever support a zAAP (or zIIP or other specialty engine which is marketing oriented). True? True. All of the specialty engines now available are meant as a way to add horsepower to a zSeries box without increasing the software costs, from both IBM and 3rd party ISVs, associated with the normal workload being run on the standard engines.. While it might be nice if Linux, running on an IFL, could dispatch a Java process on a zAAP, it is not a requirement. I would think the performance gain might be worthwhile, especially if the Linux guest was running Websphere. OK, why the stupid question? I am hoping (perhaps in vain) that eventually we may get a zAAP to do Java work on z/OS and to get back my IFL (lost during our z9BC upgrade due to lack of interest) for possible Linux on System z work. Our current management incarnation is very open towards Linux. But they still act like Linux only runs on Intel. Well, it beats the previous Windows is the solution to every problem! attitude of the previous management group. Anyway, I am fairly sure that somebody in management is going to ask something like: Why can't I run z/OS Java on an IFL? or Why can't I run z/Linux on a zAAP?. I.e. they'll want to get a single speciality CP to do both z/Linux and z/OS Java. This in order to reduce hardware costs. I know they are not expensive, compared to a general CP, but we are very cost conscious, as is reasonable. Go talk to IBM, they might be able to give you some options that we are not aware of yet. IBM has designed these specialty engines in such a manner that they can *not* run general purpose workloads, e.g., the IFL is missing an instruction that z/OS requires in order to IPL, so 3rd party ISVs can be assured that their applications will not run there. The zAAP processor may be designed such that it supports only those instructions that are used by the Java vm, and may not be capable of running zLinux at all. Hope this helps. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology -- DJ V/Soft -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

Re: OK - a really stupid question.
There are 3 flavors of DB2 nowadays DB2 for VM and VSE DB2/UDB (all ascii platforms) DB2/ for z/OS All DB2/UDBs have the same code base. Some hardware differences, but have the same features. DB2 for z/OS has a large subset of DB2/UDB, PLUS unique things for the big MVS guys. There use to be DB2 Parallel Edition, which was for RS/6000. But that code base has been folded into DB2/UDB and DB2 for z/OS. Depends on what subset of DB2 for z/OS that you are using, dictates how hard a conversion to DB2/UDB would be. Plus, DB2 on the 390 side, can back up to mainframe tape drives with your TLMS. Robotic tape systems, virtual tape systems, etc. There are a lot of utility and support functions on the DB2/UDB side that has to be redone, or rebought.
