Hello,
I'm running a manual 11g to 18c upgrade:
Oracle Restart 19.7Source Home 11.2.0.4Target Home 18.10.0.0
I have shutdown the database using srvctl from the 11g home.I have started the database using sqlplus from the 18c home in upgrade mode.I have started the upgrade using dbupgrade.
Then, a few minutes in and for no apparent reason, as can be seen in ohasd.trc, Oracle Restart tries to restart the database from the old 11g home, whilst dbupgrade is still running.It seems to start (although an ORA-600[kccsbck_first] is logged), and hilarity ensues. Ultimately the upgrade fails with CRS-5702 (resource already running) at a point where it attempts to do a restart.
My question is: why does Oracle Restart attempt to bring up the database which was cleanly shutdown before the upgrade?
I've used this approach on dozens of other databases without problems, and running dbupgrade again on this one seems to work fine too.
Thank you!Charlotte
