I was going to wait and wrap this into a blog post about setting up SAP HANA, but this is pretty important for folks wanting to use various ODBC data sources, so I wanted to get this out ASAP.
Out of the box, the Datazen server has the ability to connect via ODBC via some pre-configured options (Oracle, MySQL, etc.). There is also a catch-all option named “Generic ODBC DSN” available.
The issue with this is, you can’t pass-through a username and password using this option. This becomes a big problem if you can’t save that information in your DSN information for your ODBC data source. In fact, I’ve had that issue with two different times, once setting up a connection to SAP HANA, and the other connecting to Azure HDInsight via Hive ODBC. I got an error message like the following –
There is an easy resolution for this, but it’s a little tricky if you haven’t done it before, which I am assuming a lot of folks have not. Datazen provides the ability to extend the data providers you get out of the box by allowing you to create a custom data provider. So, I needed to create a custom data provider file that allowed me to pass-through a username/password along with the DSN name to authenticate against the data source.
I created an XML file that looked like the following so I could passthrough the Username/Password –
<name>Generic ODBC DSN With Uid/Pwd</name>
Then, I needed to create a new subfolder called dataproviderschemas on the Datazen Server at the following location –
C:\Program Files\Datazen Enterprise Server\service\
You can create a subfolder to house it in for better file mgmt of the providers you eventually create, so my final save location looked like the following –
C:\Program Files\Datazen Enterprise Server\service\dataproviderschemas\ODBC\dsnwithuidpwd.xml
Then I simply restarted the control panel instance and lo and behold, I had my new custom data provider all ready to accept username/password as part of the connection string –
That was all I needed to do – I was able to setup my ODBC connections to both SAP HANA and Azure HDInsight without issue, and I’ll walkthrough each of those in future posts. One final note – you can only use 64-bit ODBC drivers with your Datazen Server, so keep that in mind when you are downloading and setting up drivers on the server.
