I would like the same records to be also inserted into an equivalent table in a DB2 database without blocking the call that inserts into Mnesia. Is there a hook that Mnesia provides where all insertions can be trapped and where I can put my code that inserts the same record into DB2?

You could have a process subscribed to mnesia table events (see mnesia:subscribe and mnesia user guide). It would receive a message for each write and could duplicate the write to DB2.
