"parameter type is not %s"
*Cause: A conflict resolution priority function was given a type
different than the type assigned to the priority group;
or the priority group has no type assigned or a function;
or dbms_defer_sys_query was called to retrieve a deferred rpc
parameter from the deferred rpc queue, but the type of the
parameter does not match the return type of the function.
*Action: Use the function corresponding to the parameter type.
