I did an in place SQL server reporting server upgrade for 2017 SSRS.
The server has both database engine and SSRS service.

The SSRS service is the newest download from website.
I can see from reporting server configuration manager it is the standard edition and the product version is 14.0.600.594.

But some of the datasource we created before not working.
The oracle type for the connection, there is a line under it saying The data extension used here is not available. It has either been uninstalled, or it is not configured correctly.

What could be wrong?

Thanks

The extension could be missing from the config file. In the ReportServer directory, there is a rsreportserver.config file that would have the extensions listed. Open that in a text editor and in the data section there should be all of the supported extensions listed. Oracles would be:
<Extension Name="ORACLE" Type="Microsoft.ReportingServices.DataExtensions.OracleClientConnectionWrapper,Microsoft.ReportingServices.DataExtensions"/>
You pretty much want to always check the ReportServerService log file as it can provide additional information.

Did you check the Report Server log? If there are problems loading the extensions, SSRS logs that when it starts up.

I found out the reason is SSRS 2017 no longer works with Oracle 11 client. SSRS 2014 still works with it.

So I installed Oracle 12c drivers, then the SSRS oracle data source type works correctly.

Just out of interest: Which Oracle client did you use? The Instant Client or the OUI installer?

I am just wondering whether the 11g client really was broken or just needed reinstallation. There isn't such a huge difference between the two, at least so I thought....

Any links?

I used ODAC client for oracle 12c. It was ODAC 11 previously.
It was working before I upgraded from SQL server 2014 to 2017.
