This is a horse of a different color and there is more than one way to skin a cat (horse).
Evidently, IBM has privately, you have to be an ISV, gratuitously shared with them the internals of the ziip/zaap engines and how to go about configuring products to take advantage of them. Data Direct claims to have done just that; to have taken what IBM has given them, done a nice dance, and somehow faked out the operating system into thinking they are running workloads in TCB mode when infact they are running the work on a ziip/zaap in SRB mode. They also claim to have done this without violating IBM patent rights which appears credible since IBM has sued at least one ISV about this, but not Data Direct. All I can surmise is that they have somehow figured out how to run perhaps a daemon on a ziip/zaap which gets control to perform tasks on behave of regular TCB workloads like CICS. Something like a client/server, master/slave, pair process. They are very adamant, reprimanding me here last month, in stating that they positively do not run TCB workloads "as is" on a ziip/zaap since that would be a clear violation of IBM's patent rights. Evidently, it's all done with "smoke and mirrors", but the end result is the same, more MIPS, more throughput, for almost nothing. "Nice life if you can get it and you can get it if you try."
