I am testing IBM.Data.DB2 and I download las t fix dll from IBM platform. I using this sentences:

myConnectionString = "Server=0.0.0.0:000;DATABASE=LIBRARYAS400;UID=USER;PWD=PASSWORD;Pooling=false;"

        Dim myConn As DB2Connection = New DB2Connection(myConnectionString)
        
        myConn.Open()

When i use this its waits a lot of time i dont know why i dont return anything.

Thats why i am asking about other way connecting to AS400 without using ODBC.

CodePudding user response：

I wrote a library for it. It uses the 6.x version of the iSeries client. It's not well documented and I don't use it anymore but it was heavily used when I wrote it. https://github.com/MikeWills/IBM-i-.NET-Interface. If anything, use it for examples of what worked.

you can use this cool open source JDBCR4 from Scott Klement.

This is from the code test in the tool.

 endif;

   eval EnvVal = '.:'   EnvVal;
   eval EnvValChanged = *on;
 endif;
 if %scan('/sqljdbc.jar':EnvVal) = *zeros;
   eval EnvVal = EnvVal   ':/home/DUBMAPJJ01/sqljdbc.jar';
   eval EnvValChanged = *on;
