In at least some cases the system will tell you if you need to IPL with CLPA even if you forget it, as if you omit it in such cases you can get ILR027D NUCLEUS/PLPA FMID MISMATCH, RE-IPL OR REPLY 'GO' FOR COLD START I'm not positive exactly what checks it makes to decide that.
Tom Schmidt wrote But under the "Syntax rules for LPALSTxx" section in Init and Tuning Reference it also says: "Be careful not to specify the same data set name more than once in the LPALSTxx members. This applies to data sets with and without a VOLSER specified. The same data set name is concatenated as many times as it appears in all specified LPALSTxx members. Specifying the data set name more than once can cause additional processing during IPL, when the CLPA processes" As the words say, this is the case of the same data set twice in the concatenation, not the case of the same member in two different data sets in the concatenation. And the reason for not doing it is for exactly the "additional processing" reason. I don't know why we needed to bother saying this at all. It's like saying "don't tell me to do something twice when only one is necessary, because I will do exactly what you said and do it twice". As other appends correctly stated, if the same member is in two data sets in the concatenation (whether they are the same data set or not is irrelevant), the member from the first data set in the concatenation where it exists is used Peter Relson z/OS Core Technology Design ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
