Subject: Question on RACF database upgrade for z/OS 1.7->1.8
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?
Andy,
You'll have to check with IBM on the specifics of whether a 1.8 templates
will be accepted on a 1.7 system. We had a 1.5 database that IBM swore up
and down would run on 1.4, until we had to run IRRUT400 while we were still
at 1.4. IRRUT400 gagged, choked, and coughed trying to update the 1.5
database at the 1.4 level. Everything else worked, but it put a severe
crimp in our upgrade path.

Tom Conley
