19c RAC Database - using SID in tnsnames.ora file not working
We have a 2 node RAC 19c database and clients are connecting to the database remotely using tnsnames.ora file
We noticed that when the clients use SERVICE_NAME to connect to the RAC database it works but when they use SID, it does not .
We were wondering if using SID not supported anymore or is this a case of us missing something? Is there anything special we need to do to make the remote connections using SID instead of SERVICE NAMES?
This is the tnsnames entry that is not working. IF we replace the SID with SERVICE_NAME it works
