Internal connection without a proxy, InvalidOperationException RRS feed

  • Question


    Our Oracle database server throws regularly the following exception stack:


    System.InvalidOperationException: internal connection without a proxy?
    at System.Data.OracleClient.OracleInternalConnection.ProxyConnection()
    at System.Data.OracleClient.OracleInternalConnection.BeginOracleTransaction(I
    solationLevel il)
    at System.Data.OracleClient.OracleInternalConnection.BeginTransaction(Isolati
    onLevel il)
    at System.Data.OracleClient.OracleConnection.BeginDbTransaction(IsolationLeve
    l isolationLevel)
    at System.Data.Common.DbConnection.System.Data.IDbConnection.BeginTransaction

    We have no idea what reason this error has and it's not obviously how to reproduce it. Some time ago we upgraded to VB.NET 3.5 and had also some memory problems due to unallowed accesses. We tried the "3 GB switch" that enables Windows to assign more memory to programs but we couldn't hardly see any improvements.


    Has anybody had the same error and could find a way to solve it? Any other hints or suggestions?


    Thanks a lot in further!

    We get this error after we have changed from ASP 1.1 (.NET 1.1)  to ASP 2.0
    (.NET 3.5)



    best regards
