Oracle 12c error 1033 received logging on to the standby (Fixed)

If you‘re getting the Oracle 12c error 1033 received logging on to the standby, don‘t panic. This error is usually caused by a misconfiguration, and it can be easily fixed. In this blog post, we‘ll show you how to fix the error so you can get your Oracle database up and running again.

When you try to connect to an Oracle database that is in standby mode, you may receive the following error:

ORA-12500: TNS: listener failed to start a dedicated server process

ORA-12519: TNS: no appropriate service handler found

ORA-1033: ORACLE initialization or shutdown in progress

There are a few things that can cause this error.

There are two possible explanations. One is that the Oracle database is not properly configured for standby mode. Another is that the listener is not configured correctly.

To fix this error, you will need to check the configuration of both the database and the listener.

First, check the database configuration. Make sure that the standby database is configured correctly. The easiest way to do this is to use the DGMGRL utility.

Connect to the database as the SYSDBA user and run the following command:

DGMGRL> show database ‘ standby_db ‘;

If the database is not properly configured, you will see an error message.

Next, check the listener configuration. Go to the $ORACLE_HOME/network/admin directory and edit the listener.ora file.

Find the section for the standby database and make sure that the SID_LIST_ listener is properly configured.

The SID_LIST_ listener should look like this:

SID_LIST_ listener=

(SID_DESC=

(SID_NAME= standby_db )

(ORACLE_HOME= $ORACLE_HOME)

(PROGRAM= dg4odbc))

If you don‘t configure the SID_LIST_ listener properly, you‘ll see an error message when you try to connect to the database.

Once you have made the necessary changes, restart the listener. You should now be able to connect to the standby database.

Hope this helps with Oracle 12c error 1033 received logging on to the standby error.

If you are still having problems, you can contact Oracle Customer Support.

If you’re getting the “ORA-01078: failure in processing system parameters” error when trying to connect to your Oracle 12c standby database, it’s likely due to a parameter mismatch.

There are a few ways to fix this error, but the most common is to simply recompile your standby database.

1. Login to the standby server as the Oracle user

2. Shutdown the database

SQL> SHUTDOWN IMMEDIATE

3. Startup the database

SQL> STARTUP

4. Recompile the database

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;

Database altered.

5.Try to connect to the standby database again.

If you’re still getting the “ORA-01078” error, there may be a more serious issue with your standby database. In this case, you should contact Oracle customer support.
