ORA-01033 | Oracle 12c Database

Problem: While opening the session of one of the schema in pluggable database, getting error ‘ORACLE initialization or shutdown in progress‘.

An error was encountered performing the requested operation:

ORA-01033: ORACLE initialization or shutdown in progress
01033. 00000 -  "ORACLE initialization or shutdown in progress"
*Cause:    An attempt was made to log on while Oracle is being started up or shutdown.
*Action:   Wait a few minutes. Then retry the operation.
Vendor code 1033

Solution: Login the database using the sysdba. Check the status of the pluggable database.

select name, open_mode from v$pdbs ;
# In my case database name is PDB
select name, open_mode from v$pdbs where name='PDB';

So the status of the database is mounted, we have to open this database.

alter pluggable database PDB open;

Checking the database status & connection details.

Connection tested successfully.
