Notes/Domino 9.0.1 FP3 - Java Console/Controller Incompatibility

Daniel Nashed  18 February 2015 10:35:44
As discussed before, it's not a good idea to completely disable SSLv3 too soon.
Notes/Domino 9.0.1 FP3 ships with a newer JVM version that completely disables SSLv3.
The Oracle team disabled SSLV3 by default but the IBM JVM team completely removed SSLv3.

The Domino server controller and Server Console are based on Java and use the SSL/TLS stack for communication.
Domino before FP3 uses SSLv3 only -- I don't want to start any theories about why ...

The newer version with FP3 and higher use TLS 1.0 only.

That means once you updated your client you cannot communicate via server controller with an older server.
And also means that you cannot communicate from an older client once you updated your server.

There is no easy work-around beside running two different clients.
Just using a different exe does not help because the main change is in the IBM JVM.
You could keep the old client binaries and clone the data directory and run the jconsole from two different directories to avoid using two different workstations.

And information from the release notes:

9.0.1 Fix Pack 3 updates the embedded Notes/Domino JVM to 1.6 SR16 FP2 to address security vulnerabilities. This release has all of the content from the recently released POODLE and POODLE on TLS vulnerabilities in one easy to install package that includes the content from Domino 9.0.1 Fix Pack 2 Interim Fix 3 and Notes 9.0.1 Fix Pack 2 Interim Fix 4.

JVM 1.6 SR16 FP2 disabled SSLv3 and instead communicates only over TLS. If the Domino server is upgraded to 9.0.1 Fix Pack 3 (which contains JVM 1.6 SR16 FP2), the Java Console attempts to connect over SSLv3 to the JVM layer on the Domino server, which will accept only TLS connections. Applying 9.0.1 Fix Pack 3 on both the Domino server and the Java Console client will remedy the situation. For additional information, see technote 1695943 - Domino Console fails to connect to remote server after upgrading Notes or Domino to 9.0.1 Fix Pack 3
