Solution for ORA-00600: Internal Error Code, Arguments: [4193] [2206} in Oracle

In this post we will see How to solve ORA-00600: Internal Error Code, Arguments: [4193] [2206], You can encounter this error in Multitenant Environment (CDB) if your Oracle Database machine was suddenly stopped without proper shutdown command due to some unavoidable problem like Power Failure, Power cable issue, etc.

You can receive ORA-00600 for CDB$ROOT or PDB. In the first section, we showed steps to fix this error in the CDB$ROOT container, and in the later section steps to fix this error in the PDB container.

Issue in CDB$ROOT container


When we tried to start the Oracle database we received ORA-00600 during DB startup.

Step 1. Verify Local Undo Used: Startup database in mount state. and verify Local Undo is used by querying view database_properties and validate the current Undo tablespace name.

Step 2. Change undo_management to manual: In order to open the database without ORA-600 change the parameter undo_management to manual at CDB level and restart the database with the force mount option. Verify parameter undo_management set to manual, and then open the database.

Step 3. Create new undo tablespace: Create a new Undo tablespace with a different name and set this undo as Primary Undo in the init file with scope=spfile option and drop the existing Undo tablespace and restart the database.

Step 4. Create new undo tablespace: Create a new Undo tablespace with a different name and set this undo as Primary Undo in the init file with scope=spfile option and drop the existing undo tablespace. Close the PDB and restart the database.

alter system set undo_tablespace='UNDOTBS2' scope=both
