I was facing this issue mutiple times. I am not sure why. It keeps telling me that my db is in starting progress. Will update the image later, What I did everytime I am facing this issue is 1. Open Sqlplus 2. Login as sysdba using command "/as SYSDBA" 3. Change permission for your pluggadable database "alter pluggable database pdborcl open read write;" pdborcl = my pluggadable database.
