我已经按照这个[问题]（http://stackoverflow.com/questions/13691575/servicestack-ormlite-with-mutliple-database-servers）给出的答案，但我仍然得到一个错误。错误是：

我正在使用以下代码进行设置：

private void ConfigureAuth(Funq.Container container)
{
   ...
   //Create a DB Factory configured to access the UserAuth SQL Server DB
   var connStr = appSettings.Get("SQLSERVER_CONNECTION_STRING", //AppHarbor or Local connection string
   ConfigUtils.GetConnectionString("UserAuth"));
   container.Register<IDbConnectionFactory>(
                new AuthDBConnectionFactory(connStr, //ConnectionString in Web.Config
                SqlServerOrmLiteDialectProvider.Instance)
                {
                    ConnectionFilter = x => new ProfiledDbConnection(x, Profiler.Current)
                });

        //Store User Data into the referenced SqlServer database
    container.Register<IUserAuthRepository>(c =>
            new OrmLiteAuthRepository(c.Resolve<IDbConnectionFactory>())); //Use OrmLite DB Connection to persist the UserAuth and AuthProvider info

     var authRepo = (OrmLiteAuthRepository)container.Resolve<IUserAuthRepository>();
...
}

不久之后，我建立了一个与 Oracle 服务器上的空缺数据库的连接：

private void ConfigureVacancies(Funq.Container container)
{
...
var connStr = appSettings.Get ("VACANCIES_CONNECTION_STRING", //AppHarbor or Local connection string
            ConfigUtils.GetConnectionString("VacanciesDB"));

var dbFactory = (OrmLiteConnectionFactory)container.Resolve<IDbConnectionFactory>();

dbFactory.RegisterConnection("vacancies",  connStr, ServiceStack.OrmLite.Oracle.OracleDialect.Provider);
...
}

与 vacancies 数据库的连接工作正常，但是当我尝试在 auth 数据库上注册用户时，出现上述错误。在我看来，它正在坚持甲骨文方言？

我发现在连接工厂中使用了 autodispose 连接来设置 setGlobalConnection 变量：

public void RegisterConnection(string connectionKey, string connectionString, IOrmLiteDialectProvider dialectProvider, bool autoDisposeConnection = true)
{
        NamedConnections[connectionKey] = new OrmLiteConnectionFactory(connectionString, autoDisposeConnection, dialectProvider, autoDisposeConnection);
}

这是故意的吗？我修改了我的代码，将 autoDisposeConnection 设置为 False，这解决了我的方言问题并允许服务堆栈查询 Oracle 和 MS SQL。我还没有完全弄清楚将 autoDisposeConnection 设置为 false 的后果是什么。我所有的测试现在都通过了！
