Oracle Error Message
ORA-23325: parameter type is not string
Reason for the Error
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.
Solution
Use the function corresponding to the parameter type.
