Right. And they still don't, for many reasons. >(which can consist of a single LPAR or not), Strictly speaking, a Sysplex can be a single LPAR, but that is not relevant. >"IBM recommends a one-to-one relationship between the JES3 complex and the >Sysplex for ease of operations. If you do need to set up multiple global >systems within the same Sysplex, the following considerations apply...." Right. There can be more than one JES3 Global in a Sysplex, resulting in more than one JESplex. That does not mean that an LPAR can have more than one JES3 subsystem. > >One ought to assign meaning and >significance to every word, at least as a starting point. and not read something into the words that is not there. >Especially when >the recommendation was preceded by the words "it is possible." Nowhere does it say that "It is possible" to run two JES3 subsystems on the same LPAR. >I'm not sure why the previous language (apparently, by some) was misread >and misinterpreted. It certainly shouldn't have been. The previous language >was perfectly clear. The language is clear, and you have misread it to say that more than one JES3 subsystem can exist within an LPAR. I feel insulted by the tone of your comments. >http://www.redbooks.ibm.com/redbooks/pdfs/sg244582.pdf > >Section 8.12 reiterates exactly the same JES3 recommendation...and then >proceeds to provide instructions on how to violate IBM's >recommendation. :-) There's even a diagram of that multiple global (and >local) scenario, Figure 55. You have misread that diagram. The boxes illustrate processors (or LPARS), each of which has exactly one JES3 subsystem. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
