ORA-24812 is an Oracle database error code indicating an unsuccessful character set conversion. It is raised when a character set conversion to or from UCS2 fails.
Official Explanation: This indicates that a character set conversion to or from UCS2 has failed.
Common Cases: This error is most commonly encountered when a user is trying to convert a character from one character set to another, usually from one that is compatible with the database Oracle character set, to a character set that is not compatible.
Corrective Action: To remedy this error, the user should verify that the data is in the correct format for the character set being converted and then try the conversion again. If the problem persists, it could be due to a corrupt database or character set conflict, which should be addressed with the help of a certified Oracle database administrator.
