opatchauto with GI 12.2 and mixed Oracle Home 12.2 and 12.1

Hi,

we have an aplication which mandatory needs an Oracle 12.1.0.2. database. So we create a separate database in a 12.1 RDBMS home beside a 12.2 RDBMS home on a 12.2 GI (env. OL 7.4).

So far all works fine.

Now I have to patch that cluster with RU Jan 2018. It's the first time patching with that two parallel Oracle RDBMS homes.

I read that "opatchauto auto" automatically detects and patches homes for which the patch is suitable.

So my intention regarding to our mixed RDBMS cluster env is:

* perform "opatchauto apply -analyze" for checking database applicables

* shutdown all instances in 12.2 and 12.1

$ORACLE_HOME_12_1/bin/srvctl stop instance -i ....
