Answer 1

Please bve aware that FORMS_DDL is a call that was intended to be used for DDL calls. Inserts are not DDL, they are DML. There is a substantial difference between the two when it comes to commits. DDL calls automatically commits themselves. DMLs of course don't automatically commits.
Inserts should be done from client or db side PLSQL and them a commit should be issued from that same code. If you must send DML SQL code to the database from a text file, use something like SQL*Plus or some other command line tool and include the commit in the SQL.
