Yes I agree Brent that is the workaround that the changes in 12.1.0.2 were
meant to address. I am interested in understanding why it was not seen as
reasonable to start the pdb databases up after a container restart

You could create a database trigger after startup that has the following

execute immediate 'alter pluggable database all open';

Now 12.1.0.2 allows you to save a state in advance using ‘alter pluggable
database xxx save state’ which does seem a step forward

However why would the default not be to start all the pluggable databases (or
services as they are seen) not leave them in a mounted state. Obviously Oracle
have thought about this and changed the trigger method, maybe due to customer
feedback but I wonder why they have not gone the whole hog and started the
services automatically.
