ORMLite Dialects - ormlite-servicestack

Question

I have followed the answer given to this [question] (http://stackoverflow.com/questions/13691575/servicestack-ormlite-with-mutliple-database-servers), but am still getting a error. The error is:

I am setting things up with the following code:
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>();
...
}
A little later I set up a connection to a vacancy database held on an oracle server:
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);
...
}
The connection to the vacancies database works fine, but when I try to register a user on the auth database I get the error above. It seems to me that it is holding onto the Oracle Dialect?

Answer 1

I've dicovered that the autodispose connection is being used in the connection factory to also set the setGlobalConnection varible:
public void RegisterConnection(string connectionKey, string connectionString, IOrmLiteDialectProvider dialectProvider, bool autoDisposeConnection = true)
{
NamedConnections[connectionKey] = new OrmLiteConnectionFactory(connectionString, autoDisposeConnection, dialectProvider, autoDisposeConnection);
}
Is that intentional? I've modified my code to set autoDisposeConnection to False, this fixes my dialect problem and allows service stack to query Oracle and MS SQL. I've not quite worked out what the consequence of setting autoDisposeConnection to false is. All my tests are passing now though!
