Hi Just starting to plan the 1.7-> 1.8 z/OS upgrade
We have a four-system sysplex and intent to go to 1.8 by doing a rolling update over a week. Ie there will be about a week with some systems running z/OS 1.8 and some running z/OS 1.7 One thing I can't seem to find unambiguous information about is the update path for the RACF database, ((which is shared by all systems in the plex)) At the moment we plan to do the following: a) ON a 1.7 SYSTEM run IRRMIN00 UPDATE at level 1.8 (ie with the service pack library STEPLIBed) against the 1.7 primary database. b) ON a 1.7 SYSTEM run IRRMIN00 UPDATE at level 1.8 (ie with the service pack library STEPLIBed) against the 1.7 secondary database. c) Run for a few days d) IPL some systems from the 1.8 residence pack e) Run for a few more days doing other testing f) Ipl all systems from the 1.8 residence pack Is this safe? Will the 1.7 systems tolerate the 1.8 templates in the database? Or should we go the other way and do the upgrade after we IPL to 1.8? Hope this is clear. ---------------------------------------------------------------------- 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
