In particular, the zAAP was created to allow people to run Java on z/OS without incurring the software costs that they would have if they have if they had to increase their MSUs on GP engines to do so. This was to sell WebSphere Application Server (a Tomcat like environment) when IBM was strongly pushing the "you can run your Java Enterprise software on z/OS instead of on Intel" idea. That gave rise to the other specialty engines. IMO, the best specialty engine is the IFL to run zLinux without increasing your z/OS software costs. Linux on z would have died if it were tied to normal GPs. Mainly due to the "CEC MSU" pricing that some software vendors use. Imagine the cost if you dedicate 3 CPs to Linux, but had to pay your z/OS vendors as if you were using them for z/OS because "well, you _could_ do so, so we will charge you because we are assuming that you are doing so." I hate the current software pricing. And, no, I don't have a genius idea for something better. > > Scott > > -- Unix: Some say the learning curve is steep, but you only have to climb it once. -- Karl Lehenbauer Unicode: http://xkcd.com/1726/ Maranatha! <>< John McKown ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
