The PLPA data set should be allocated first, as a one-cylinder data set, with the COMMON data set allocated second, immediately following the PLPA data set on the same volume. The size of the COMMON data set should be large enough to contain both PLPA and COMMOND pages. This causes the vast majority of PLPA pages to be written to the COMMOND page data set during IPL. This allows the operating system to use the chained CCWs within a single data set and improves performance when both data sets are on the same volume. The message (ILR005E PLPA PAGE DATA SET FULL, OVERFLOWING TO COMMON DATA SET) during IPL can be ignored when the PLPA and COMMON page data sets are on the same volume. </quote> ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
