Hi Ryan,
1. I am unable to access the documentation link, kindly re-share it.
2. Yes, CA TDM Portal will not support TNS names, but due to security reasons Client has given access to DBs to connect via HOST IPs but not from Host names. As we have ORACLE RAC DB servers, each Oracle DB host service has 3 IPs and the connection ping can reach DB via any of the 3 IPs, and each time it takes random IPs out of 3.
In CA Subset tool, this issue is addressed by providing option to enter multiple IPs with its Ports, and the connection type is ORACLERAC.
how to go forward in my case?
