| ERROR | parameter type is not string |
| 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. |
