If service is requested from a transaction process and the UAP requested for service has the transaction attribute, processing for the service request is transaction processing. Such service requests can be handled through nontransactional processing (nontransactional RPC). To effect nontransactional processing, specify the argument to the function dc_rpc_call() to indicate a nontransactional RPC.

For details on the transaction attribute, see 2.3.3 Specification of transaction attribute.
