ODP.NET 실행 중 ReportViewer가 실행 중임

Question

웹 응용 프로그램에서 Microsoft ReportViewer (2012)를 사용하여 보고서를 표시합니다. LocalReport와 일반 DataTable을 사용하여 데이터 소스를 제공합니다. DataTable은 ODP.NET으로 채 웁니다. 하나의 보고서를 실행할 때 모든 것이 정상이지만 두 개의 보고서를 동시에 실행하면 하나의 보고서 만 다른 ODP.NET 쿼리를 완료 할 때까지 대기 한 다음 두 개의 보고서를 렌더링합니다. 일부 디버깅을 할 수 있지만 솔루션을 찾을 수 없습니다. 아래 디버그 정보, 아무도 날 anlyze 문제를 도울 수 있습니다. 감사. 내 가난한 영어 미안해.

백그라운드 스레드가 ODP.NET 쿼리를 실행하는 동안 보고서 하나가 렌더링되지 않습니다. 이유는 무엇입니까?

Answer 1

내가 알아낼 것 같아. 나는 THRE 오라클 저장 프로 시저를 호출하는 OracleClob 입력 매개 변수를 가지고 있고이 같은 매개 변수를 설정합니다

OracleClob tempLob = new OracleClob(connection); 
if (paramValue != null) 
{ 
    byte[] tempbuff = Encoding.Unicode.GetBytes((string)paramValue); 
    tempLob.BeginChunkWrite(); 
    tempLob.Write(tempbuff, 0, tempbuff.Length); 
    tempLob.EndChunkWrite(); 
} 
parameter.Value = tempLob; 

문제는 난 그냥 GC 파이널 할 수 있도록, tempLob 설명서를 버리지 않는입니다. 한편, reportviewer가 매개 변수를 설정하거나 가져 오려고하면 먼저 quest first clr stack show처럼 보고서를 컴파일합니다. reportviewer는 임시 AppDomain을 작성하여 보고서를 컴파일하고 컴파일 한 후이 AppDomain을 언로드합니다. 따라서 AppDomain을 언로드 할 때 clr은 모든 스레드를 일시 중단하고 해당 AppDomain ...에 대한 관련 스레드를 찾은 다음 GC가 호출되므로 개체의 Finalize 메서드도 호출됩니다. OracleClob의 Finalize가 호출되면 CriticalSection으로 들어가 메모리를 비 웁니다. 하지만 지금은 다른 스레드가 ODP.NET 쿼리를 실행하고 기다리는 결과입니다. CriticalSection에도 있습니다. 쿼리가 완료 될 때까지 기다리는 finalize 메서드를 수행하십시오. 이 현상은 질문과 같습니다. 여기 디버그 정보가 더 있습니다 : 스레드의 기본 스택을 마무리합니다.
