Hi, I am facing an issue while registering my database to the ArcGIS Server. When i register the database to the server it throughs me following error:

Following configurations are done in the ArcGIS Enterprise ecosystem I am working on:
- ArcGIS Server 11 and Portal for ArcGIS installed on the same machine with separate web adaptors.
- ArcGIS Datastore configured with Relational, Spatiotemporal, Graph and Tile Cache extensions.
- ArcGIS Pro 3.0 installed on separate machine.
- ArcSDE is installed on the third separate machine.
- Oracle 19c 64 bit client installed on both ArcGIS pro and ArcGIS server machines.
- Environment variable set to orahome\bin folder.
I am able to connect to the 19c database from ArcGIS pro but unable to register this database to ArcGIS server. Anyone have clue that where is the problem exist??
