You can create an exceptions table and re-execute your statement adding
the exceptions into exceptions clause -- assuming your exceptions table
is named exceptions. You can then identify the orphaned records by
rowid.

The script is probably named something like ?/rdbms/admin/utlexcpt.sql
(close enough).

select * from exceptions;

SELECT * FROM &child_table_name WHERE ROWID IN (SELECT ROW_ID FROM
EXCEPTIONS);
