I’d wager that this is a Java restriction, as opposed to IS (i.e., AT).
The following steps should work for AT as well, since it is hosted on an IS. I won’t recommend using TLSv1 (or TLSv1.1 for that matter), but if you absolutely must, then try this -
- Navigate to /SAGInstallationPath/jvm/jvm/jre/lib/security folder
- Edit the java.security file
- Find the key jdk.tls.disabledAlgorithms
- Remove TLSv1 from the list of disabled algorithms
- Restart the IS and try the JDBC connection again
