프로그래밍 방식으로 원격 패키지 로드 및 실행

Integration Services 패키지는 파일 또는 SQL Server에서 직접 로드하거나 SQL Server와 특수한 파일 시스템 폴더 모두의 패키지 저장소를 관리하는 SSIS 패키지 저장소에서 로드할 수 있습니다. 이 예제에서는 Select Case 또는 switch 구문을 사용하여 패키지를 시작하기 위한 적절한 구문을 선택하고 입력 인수를 적절하게 연결함으로써 사용 가능한 모든 옵션을 지원합니다. LaunchPackage 웹 서비스 메서드는 클라이언트 컴퓨터에서 Integration Services 어셈블리에 대한 참조가 필요하지 않도록 패키지 실행 결과를 DTSExecResult 값 대신 정수로 반환합니다.

다음 예제 콘솔 응용 프로그램에서는 웹 서비스를 사용하여 패키지를 실행합니다. 웹 서비스의 LaunchPackage 메서드는 클라이언트 컴퓨터에서 Integration Services 어셈블리에 대한 참조가 필요하지 않도록 패키지 실행 결과를 DTSExecResult 값 대신 정수로 반환합니다. 이 예제에서는 DTSExecResult 값을 미러링하는 값을 포함하는 전용 열거형을 만들어 실행 결과를 보고합니다.
