Oracle DB Error ORA-12495 cannot disable an enabled level, category, or release category

The following is the cause of this error:

You attempted to disable a level, category, or release category that had previously been enabled. An enabled label definition may exist in some database label, so it cannot be disabled.

Action you can take to resolve this issue: If the label definition is no longer valid, change its name to one that identifies it as invalid. When any labels are converted to character strings, the new label definition will be used.
