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?

Hello,
I'm using Mirth interface engine which is based on Java technology

the connection string is   :

dbConn = DatabaseConnectionFactory.createDatabaseConnection('sun.jdbc.odbc.JdbcOdbcDriver','jdbcSurprisedbc:EM_Conn_Testing','Admin','DBAdmin');


"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 ?!

Hi Hosam,

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

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 ?!

The error "Data source name not found" would be one to tackle - your DSN
is not properly setup in Windows would be my guess.

most likely DSN is defined for current user only (and service would not
be able to see it) or you have a 32bit DSN and 64bit service or vice versa.
