NHibernate 事务提交失败

Question

在生产中，我在提交 Nhibernate 事务期间遇到了偶发性超时异常。但是我期望更新的记录是正确的！在舞台环境中没有什么可报告的。

下面是我的批处理程序的应用日志。

下面是我的批次结构

    private static ITransaction tx;

    public virtual BatchResponseStatus Run(string[] args)
    {
        var response = BatchResponseStatus.Success;

        try
        {
            //Do some stuff 

            SetTransaction();

            //Collect elements to be processed

            foreach (var item in aListOfItem)
            {
                // Stuff

                // Call methods that creates, reads  or updates records 
                // with Fluent Nhibernate or Sql Server Stored procedure

                // Write some files 

                // Zip files

                // Update DTO
            }

            tx.Commit();
        }
        catch (Exception ex)
        { 
            RollbackTransaction();
            XXRepository.NhSession.Clear();
            response = BatchResponseStatus.Error;
        }
        finally
        {
            DisposeTransaction();
        }

        return response; 
    }

    private void SetTransaction()
    {
        tx = XXRepository.NhSession.BeginTransaction(IsolationLevel.ReadUncommitted);

        if (tx == null)
                throw new Exception("Impossible create a Transaction");
    }

    private static void RollbackTransaction()
    {
        if (tx != null)
        {
            tx.Rollback();
        }
    }

我使用这项技术：

Sql 服务器存储过程
Nhibernate 3.4（流畅的 Nhibernate）
.Net Framework 4.5

有人可以帮助我吗？谢谢

连接超时。这意味着，连接超时，但在 Sql 服务器中继续提交。正如您在日志中所见，回滚失败，因为连接已提交。恕我直言，Sql客户端实现未正确处理连接超时。

有一个 forum thread 讨论了这个问题。
