Makes permanent all the changes you made to relational and Oracle
       CODASYL DBMS databases since the most recent COMMIT or ROLLBACK
       statement or, if you have not performed a COMMIT or ROLLBACK,
       since the first database READY command.

       The COMMIT statement does not affect collections; collections
       are maintained. For Oracle CODASYL DBMS databases, the COMMIT
       statement performs a COMMIT RETAINING. For relational databases,
       the COMMIT statement starts a new transaction that gives you a
       new look at the database.

       When you have both relational and Oracle CODASYL DBMS databases
       readied, the COMMIT statement commits all Oracle CODASYL DBMS and
       relational databases, regardless of whether you made any changes
       to their data.

       Domains based on RMS files are not affected by the COMMIT
       statement.
