Information in this document applies to any platform.
Administrators of Oracle Secure Global Desktop (SGD) deployments may receive reports that clients are unable to connect to the SGD Gateway after application of the July 2015 JVM Update patch, 1.8.0_51.
In this scenario, connecting clients may appear to freeze at the client splash screen after authentication. Users who have manually started the client may be presented with an error suggesting, "connection has been reset." These symptoms are triggered when connections from the gateway are rejected by the ttassl process on the SGD server.
SGD Administrators may find errors logged in parallel with client connection failures, similar to the following:
The client has established a TCP connection but failed to negotiate an SSL connection. Connection closed by Secure Global Desktop Security Daemon.
Reported SSL error: no shared cipher
Check the client supports SSL.
Web browsers must support JDK 1.1. ssldaemon/handshake/failederror
This unique condition may manifest only in the following deployment scenario:
- A production 5.1 SGD deployment has been previously upgraded to SGD 5.2.
- Version 5.2 of the SGD Gateway is used in the environment to securely proxy connections for the upgraded 5.2 SGD array.
- The optional July 2015 JVM Update has recently been applied to the SGD Gateway.
