I like the core of your idea. All levels might be too much to manage (7 model generations with IBM's currently supported z/OS releases), but shipping this trio could make commercial sense (as an example): Level C: Runs on all IBM supported z/OS releases (currently z900/z800 systems or higher) Level B: Runs on most recent three model generations (currently z196, z114, zEC12, zBC12, and z13) Level A: Runs on current model generation (currently z13) Level A, B, or C could be chosen based on a parameter, post installation. That'd be safer for DR purposes, for example. Level C is "universal," Level B is "all possible Parallel Sysplex system configurations incorporating the current model," and Level A is "current model." Level B is also "performance optimized during migration steps to current model," and Level A is also "performance optimized for current model." -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM z Systems, AP/GCG/MEA E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
