LFAREA (Large Frame Area) provides frame space for both fixed and pageable large pages. We specify: LFAREA=7782M, Large frame area which is more than enough for our needs. Right after IPL I see some fairly small numbers: D VS,LFAREA IAR019I 13.56.52 DISPLAY VIRTSTOR 507 SOURCE = 20 TOTAL LFAREA = 7782M , 0G LFAREA AVAILABLE = 7257M , 0G LFAREA ALLOCATED (1M) = 0M LFAREA ALLOCATED (4K) = 311M MAX LFAREA ALLOCATED (1M) = 0M MAX LFAREA ALLOCATED (4K) = 311M LFAREA ALLOCATED (PAGEABLE1M) = 214M MAX LFAREA ALLOCATED (PAGEABLE1M) = 214M LFAREA ALLOCATED NUMBER OF 2G PAGES = 0 MAX LFAREA ALLOCATED NUMBER OF 2G PAGES = 0 Of course, these numbers grow over time... -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 http://www.phoenixsoftware.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
