As a result of removing old-style (V2) triggers, V2 user exits have also been removed.
The following user exits, which are hard-coded callbacks to V2 trigger functionality, have been removed. It is now assumed that any calls to these user exits call a user-defined user exit rather than a built-in one.
You should recode any code that uses these callbacks to PL/SQL:
COPY
ERASE
HOST
EXEMACRO
EZ_GOREC
EZ_CHKREC
