When I install DataMaker,  it is using an Oracle 11g client,  but I need to use a 12g client to work with my Oracle 12g database. Is there a way to upgrade the client

Datamaker uses an Oracle Instant Client that is located under (C:\Program Files (x86)\Grid_Tools\)GTDatamaker folder. We have not tested Datamaker using later versions and we don’t have a process to upgrade the Oracle instant client.  We will look into shipping a later version with the product in a future release.


There is a workaround, but it’s not QA’ed. What you can do is download the Oracle Instant Client from the following location ( ) by unzipping the contents to your GTDatamaker folder. Just grab the version “Instant Client Package - Basic: All files required to run OCI, OCCI, and JDBC-OCI applications” 


Make sure your TDM services are down when overlaying the Oracle Instant Client files.
