How To Fix the “ORACLE initialization or shutdown in progress” Error

Summary: in this tutorial, you will learn how to fix the ORACLE initialization or shutdown in progress error when you connect to the Oracle Database.

Sometimes, you may encounter the following error when you connect to an Oracle pluggable database in Oracle Database 12c:

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
Code language: SQL (Structured Query Language) (sql)

To fix this issue, you use the follwing steps:

First, launch the SQL*Plus program and login to the database instance as a SYSDBA user:

Enter user-name: ot@pdborcl as sysdba Enter password: <password>
Code language: SQL (Structured Query Language) (sql)

This statement connected to the PDBORCL database using the OT user.

Second, issue the following statement to check the status of the current instance:

SQL> select status, database_status from v$instance; STATUS DATABASE_STATUS ------------ ----------------- MOUNTED ACTIVE
Code language: SQL (Structured Query Language) (sql)

The output showed that the instance status is mounted.

Third, change the state of the Oracle Database instance to OPEN:

SQL> alter database open; Database altered.
Code language: SQL (Structured Query Language) (sql)

For more information on the Oracle Database stages, check it out the Startup Oracle Database instance tutorial.

Finally, double check the database status by using the following statement:

select status, database_status from v$instance; STATUS DATABASE_STATUS ------------ ----------------- OPEN ACTIVE
Code language: SQL (Structured Query Language) (sql)

The instance status is open and available to all users for normal operations.

Now, you should be able to connect to the OT pluggable database without any issue.
