Xp_ora2ms_exec2 fails with the following error when only TLS 1.1 or TLS 1.2 is enabled:
SSL Security error ConnectionOpen (SECDoClientHandshake()).I disabled TLS 1.0 and other weak ciphers through the registry. My SQL Server version is 2016. My OS is Windows Server 2016. My SSMA for Oracle Extension Pack version is 7.6.0. The only solution I have tried is to set the .NET framework to use strong cryptography (also through the registry). It did not work.
