Oracle Message ORA-10668 - Inject Evil Identifiers

ERRORInject Evil Identifiers
CAUSEevent 10668 is set to some number > 0, causing 1/(value-1) of all identifiers to be replaced by a maximum amount of xs. It is common for an identifier to be parsed once with a max of 30 bytes, then reparsed later with a max of 4000, so it may not be possible to inject such an identifier without the aid of this event. A value of 1 causes no identifiers to be corrupted.
