OD 6
Java 1.6

Hello,
SQL server was upgraded from 2012 to 2016 and we are getting the following error where the app tries to access new DB. We have updated the new SQL credentials on the app xml file on ../local host file and restarted tomcat.

The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: "java.lang.RuntimeException: Could not generate DH keypair

Please advice on troubleshooting this.

Thanks in advance.

Possibly you need to update the Oracle client jar?

Googling "sql server Could not generate DH keypair". It suggests Java 1.7 might solve your problem. It's between Java and your sql server.

With the same driver connection works on dev system with the dev DB. It is the same SQL version(2016). This is the production that is failing.
Didn't do any java update on dev system either. Only difference is that the test DB is on windows 2012 R2 and Prod is on Win 2016.

You would need some help from Microsoft like digging into its knowledge base and tech support.

Will OD6 work with jre 7 or 8?

It should, but it is not a "tested/supported" configuration.

Yes
