If you run the iModel Connector for Smart Instrumentation and the installed driver field is empty, it may be due the missing registry entries. The Oracle connection in the iModel Connector for Smart Instrumentation requires two fields to be populated:
Note: The key (in red) will vary depending on the version of Oracle.
Without these two registry entries the “Driver” field in the connection form will be blank (ref. Figure 1)
Figure 1 – Without Oracle Installed driver field is empty.
If you encounter this when running the connector, you can fix this by running the the Oracle 19c Database installer which will update both registry keys.
