구조는 이렇습니다...
지금 현재는 ASP.NET --> 웹서비스(SQL 작성) --> com+ 호출 구조입니다.
<ASP.NET>
        Dim oDataSet As New DataSet()
        Dim oDAL As New ZAA010T()
        fnQuery = ""
        Try
            fnQuery = oDAL.GetZaa010T(sMajorCd, sCodeName, oDataSet)  ---> 웹서비스 호출
            If fnQuery <> "" Then Throw New Exception(fnQuery)
            rptSheet1.DataSource = oDataSet
            rptSheet1.DataBind()
        Catch err As Exception
            fnQuery = "[fnQuery]" & vbCrLf & err.Source & vbCrLf & err.Message & vbCrLf & fnQuery
        Finally
            If Not oDataSet Is Nothing Then
                oDataSet.Dispose()
                oDataSet = Nothing

            oDAL = Nothing

위와 같은 구조로 되어 있는데...요는
com+ 에서 하나의 함수에서 SetComplete 혹은 SetAbort 를 하는데....
SQL 을 하나만 실행한다는 보장이 없거든여.....하나의 함수에서 INSERT , UPDATE, SELECT 등 여러개의 문장이 있을 수 있는데...
그래서 SQL을 실행만을 전담하는 com+(?) 을 따로 만들어서 사용하고 싶은데....
    [Transaction(TransactionOption.Required, Isolation = TransactionIsolationLevel.ReadCommitted), JustInTimeActivation(true),
 EventTrackingEnabled(true)] 와 같은 속성을 어떻게 설정을 해야 하는지요?
예를 들어...
SELECT 만을 실행하는 함수가 GetRecordset, insert, update 등을 실행하는 함수가 ExecuteSQL 로 가정하면...
임의함수 COM+ aaaa 에서 GetRecordSet, ExecuteSQL 함수를 호출 할 경우 트랜잭션이 함께 묶이는지요?
그런 구조를 만들고 싶은데....조언 좀 부탁합니다...
ps. 이야기가 잘 전달이 되었는지...
