19c : Placing a Database into a Quiesced State

Hi,

I was trying the Quiesced State feature for my DB but found out it cannot be done for a multitenant architecture!

My version is 19.9 and this is the error I get when trying the following command in my PDB:

ALTER SYSTEM QUIESCE RESTRICTED;
ORA-25511: quiesce not supported for pluggable databases

Ok fine, I find it strange it should be done at CDB level, but the same kind of error doing it from the CDB:

ORA-25510: quiesce not supported for the root container

Ok, if I get it correctly, you cannot quiesce an instance anymore in a multitenant architecture. So be it, but why the whole thing in the 19c Administrator's guide:
