Getting ORA-01033: ORACLE initialization or shutdown in progress

Question

Yesterday I installed Oracle 12c Enterprise edition on my laptop. When I tried to connect to DB via SQLPLUS i got the below error

C:\Users\USER>sqlplus

SQL*Plus: Release 12.1.0.2.0 Production on Sun Feb 28 14:12:46 2016

Copyright (c) 1982, 2014, Oracle.  All rights reserved.

Enter user-name: userdb
Enter password:
ERROR:
ORA-01033: ORACLE initialization or shutdown in progress
Process ID: 0
Session ID: 0 Serial number: 0

I tried all the tricks mentioned on internet but couldn't get rid of this error.

I also tried below

SQL> shutdown immediate;
ORA-01109: database not open


Database dismounted.
ORACLE instance shut down.
SQL> startup;
ORACLE instance started.

I've had the same problem and just want to share my solution with you, if anybody else gets the ORA-01033: ORACLE initialization or shutdown in progress Error in Oracle 12c Database. My database showed me the error everytime i tried to connect to a user of a sample schema (for ex. hr).

The following worked for me:

SQLPlus> connect sys as sysdba
SQLPlus> alter pluggable database all open;
