The supported installation platforms for the SGD Gateway host are listed in the Oracle Secure Global Desktop Platform Support and Release Notes for Release 4.7 available at http://www.oracle.com/technetwork/documentation/sgd-193668.html.
The following requirements apply for the SGD servers used with the SGD Gateway:
Secure mode. By default, the SGD Gateway uses secure connections to SGD servers. Your SGD servers must have secure connections enabled. Firewall forwarding must not be enabled.
In a standard installation, an SGD server is configured automatically to use secure connections. See "Secure Connections to SGD Servers" in Chapter 1 of the Oracle Secure Global Desktop Administration Guide for Release 4.7 if you need information on how to secure an SGD server.
SGD version. The SGD servers must be running at least version 4.5 of SGD. It is best to use version 4.7 of the Gateway with version 4.7 of SGD.
Clock synchronization. It is important that the system clocks on the SGD servers and the SGD Gateway are in synchronization. Use Network Time Protocol (NTP) software, or the rdate command, to ensure that the clocks are synchronized.
For more information on SGD server system requirements, see the Oracle Secure Global Desktop Platform Support and Release Notes for Release 4.7.
