오늘도 어김없이 뎁질좀 하다가 스마트클라이언트 관련 질문이 올라왔다.
질문인 즉, Infragistic 컴포넌트를 사용하니 로컬에선 잘 되는데 원격접속시 다운로드가 제대로 되지 않는 것 같다는 것이다.
 
데브피아 Q&A 원문 :
http://www.devpia.com/MAEUL/Contents/Detail.aspx?BoardID=7&MAEULNO=5&no=70422&ref=70422&page=1
 
아래의 샘플 경로는 접속할 수 없습니다.
샘플 :
우선 예시 상황을 만들어 보았다.
아래는 버추얼PC 로 Infragistic 컴포넌트가 설치가 되지 않는 Windows XP 환경이다.
 
 
Fiddler 를 이용하여 어셈블리 다운로드 상태를 보도록 하자.
 
 
예상대로 어셈블리를 제대로 다운받지 못하여 발생하는 엑박 이라는 것을 알 수 있다.
 
Infragistic 은 최초 설치 시 GAC 에 등록되어 컴포넌트 참조시에 GAC 에 등록된 어셈블리를 참조하게 된다. 때문에, 참조된 어셈블리는 로컬 복사가 이루어 지지 않는다. 더 쉽게 말해, bin 폴더에 Infragistic 의 DLL이 복사되지 않는다.
 
그럼 다음과 같이 참조된 어셈블리를 하나의 DLL 로 떨어질 수 있도록 참조 속성을 변경해주자.
 
 
그럼 다음과 같이 Infragistic 컴포넌트가 설치 되지 않은 PC 에서 정상적으로 작동이 될 것이다.
 
 
C:\Visual Studio 2005 명령 프롬프트>GACUTIL /L
 
위와 같이 비쥬얼 스튜디오 명령 프롬프트를 통해 GAC 에 등록된 어셈블리를 확인할 수 있다.
 
 
만약 예리한 사람이라면 여기에서 굉장히 비효율성을 느낄 것이다.
DLL 모듈의 업데이트가 필요없는 구성요소에 대해 매번 GAC 과 로컬 Cache 를 뒤져가며, 버전체크 하려 할 것이다.
 
Fiddler 를 통해 GAC 에 등록된 어셈블리와 그렇지 않은 어셈블리를 찾아 헤메는 과정이다.

[바인딩 로그 2] Infragistic 컴포넌트가 GAC 에 등록되지 않았을 때 바인딩 로그
 
[바인딩 로그 1] 에서는 GAC 등록된 어셈블리를 로드 하였다. 참고로 GAC 에 등록된 어셈블리는 Windows폴더의 Assembly 안에서 확인할 수 있다. ( GACUTIL /L 과 동일 )
하지만, [바인딩 로그 2] 에서는 GAC 에서 찾지 못했다는 통보와 함께 다운로드 캐시에서 어셈블리를 찾았다는 로그를 남겨 놓는다.
 
그렇다면, 스마트클라이언트가 화면에 나타나기까지 동적인 업데이트(웹으로부터 업데이터)가 필요없는 어셈블리에 대해서 GAC 에 등록하는 것이 다운로드 속도를 증가하는 것을 알 수 있다.
 
그럼 이런 어셈블리는 어떻게 GAC 에 등록을 하면 될까~?
방법은 ClickOnce 를 통한 배포로 가능하다. ClickOnce 의 부트스트래퍼를 통해 필수구성요소로써 Infragistics 어셈블리를 배포하는 것이다. 하지만 이 내용은 이번 아티클에 포함하기엔 약간은 방대한 분량이라 다음 기회에 다시 다루어 볼 예정이다.
 
우연히 뎁질(데브피아 놀이) 하다가 팁으로 올리려다 이렇게 글이 길어지게 되었기에, 내일 아침도 뻐근한 목을 부등켜 잡고 출근해야 할 것 같다. 아훔 +_+
