I am using oracle 12c database and using CDB's and PDB's. Currently all PDB's created are in NORMAL state.
Can anyone in the forum help me to set the PDB status to UNUSABLE ?

I am not able to get any information on how to forcibly or manually , set or move the state of PDB from "NORMAL" or any "NEW" state to "UNUSABLE" state from oracle documentation ?

Can you please help me with the suggestions as i need to test the PDB in the UNUSABLE state.
