A database statement is processed in a multi-server system, in a manner to
increase the possibility that slave server processes on remote nodes will
generate execution plans that are equivalent to the corresponding
execution plan generated by the query coordinator process. A set of hints
is generated based on the same information on which the master plan is
based. The set of hints is sent to remote nodes, where respective remote
plans are generated based in part on the set of hints. Use of the hints
in generation of the remote plan increases the possibility that the
remote plan will be equivalent to the master plan and that the slaves on
the other database server will be able to join in parallel processing of
the database statement.
