Chris Holland SEC Solutions Ltd. ![]() | Hi Hosam,
Is the problem in connecting or in executing some SQL? If it is in connecting can you post your connection string here please?

Hosam MEMITS Solutions | Hello,
I'm using Mirth interface engine which is based on Java technology the connection string is : dbConn = DatabaseConnectionFactory.createDatabaseConnection('sun.jdbc.odbc.JdbcOdbcDriver','jdbc ![]() "EM_Conn_Testing" is the ODBC connection name to DBISAM DB the problem is not in the connection it is working fine sometimes but in other times it gives errors I test it using 32 JRE it is working fine also but some times the MIRTH engine is crashed when it tries to connect to DBISAM using ODBC my question now is DBISAM ODBC driver should be stable when working with JAVA or the problem can be from other sources ?! is ODBC stable enough to develop a heavy application using it? is C# better than JAVA for developing an application that connected to DBISAM ?! because we don't have programmers from our team who know Delphi !! any suggestions from your side, please ?! |

I use C# (and .NET) with the ODBC driver for very disk intensive applications and it is rock solid with multiple users.

Hosam MEMITS Solutions | Hello Chris
we developed a c# windows service to get the data from DBISAM and put it in MySQL to be used by Mirth (JAVA integration engine ) the app working fine inside the C# visual studio but when we run it as a stand-alone service it gives us the below-attached error: the connection string is simply as : private static readonly string connectionStgDBisam = "DSN=EM_Conn_Testing2"; any suggestions to fix that, please ?! System.Data.Odbc.OdbcException (0x80131937): ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified at System.Data.Odbc.OdbcConnection.HandleError(OdbcHandle hrHandle, RetCode retcode) at System.Data.Odbc.OdbcConnectionHandle..ctor(OdbcConnection connection, OdbcConnectionString constr, OdbcEnvironmentHandle environmentHandle) at System.Data.Odbc.OdbcConnectionOpen..ctor(OdbcConnection outerConnection, OdbcConnectionString connectionOptions) at System.Data.Odbc.OdbcConnectionFactory.CreateConnection(DbConnectionOptions options, DbConnectionPoolKey poolKey, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.CreateConnection(DbConnectionOptions options, DbConnectionPoolKey poolKey, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningConnection, DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionFactory.CreateNonPooledConnection(DbConnection owningConnection, DbConnectionPoolGroup poolGroup, DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionFactory.TryGetConnection(DbConnection owningConnection, TaskCompletionSource`1 retry, DbConnectionOptions userOptions, DbConnectionInternal oldConnection, DbConnectionInternal& connection) at System.Data.ProviderBase.DbConnectionInternal.TryOpenConnectionInternal(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource`1 retry, DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionClosed.TryOpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource`1 retry, DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionInternal.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.Odbc.OdbcConnection.Open() |
