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

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 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.

SQL> alter session set container=PDB1;

Session altered.

SQL>  create undo tablespace UNDOTBS2 datafile '/u01/oradata/PDB1undotbs02.dbf' size 100m autoextend on maxsize unlimited;

Tablespace created.

SQL> alter system set undo_tablespace='UNDOTBS2' scope=both;
alter system set undo_tablespace='UNDOTBS2' scope=both
