In the Administration Console, the Global Settings tab is where you configure the settings that apply to SGD as a whole. See Figure 3.26, “The Global Settings Tab”.
The Global Settings tab contains other tabs for configuring and managing SGD. For example, the Secure Global Desktop Authentication tab is where you configure how users authenticate to SGD.
In the Administration Console, the Secure Global Desktop Servers tab is where you manage individual SGD servers. See Figure 3.27, “The Secure Global Desktop Servers Tab”.
The Secure Global Desktop Servers tab shows you the status of an SGD server, whether it is running, how many user sessions there are, and how many application sessions the server is hosting.
When you click the name of an SGD server in the Secure Global Desktop Servers List table, the Administration Console displays further tabs in Object View. You use these tabs to configure and manage the selected SGD server. See Figure 3.28, “The General Tab for an SGD Server”.
On the command line, you use the tarantella config command to configure global settings and SGD servers. The Oracle Secure Global Desktop Administration Guide has details of all the command-line arguments.
The Secure Global Desktop Servers tab enables you to group SGD servers together to form an array. An array is a collection of SGD servers that share configuration information.
An array contains the following:
One primary server – This server is the authoritative source for global SGD information, and maintains the definitive copy of the organizational hierarchy
One or more secondary servers – The primary server replicates information to these servers
A single, standalone server is considered to be the primary server in an array with no secondary servers.
SGD servers in an array may run different operating systems. However, all the array members must run the same version of SGD.
Arrays have the following benefits:
User sessions and application sessions are load-balanced across the array. To scale more users, simply add more SGD servers to the array.
With more than one server, there is no single point of failure. You can decommission a server temporarily with the minimum of disruption to your users.
Configuration information, including all the objects in your organizational hierarchy, is replicated to all array members. All array members have access to all information.
Users see the same workspace and can resume applications no matter which SGD server they log in to.
You add an SGD server to an array by clicking Add in the Secure Global Desktop Servers List table.
You can keep track of what your users are doing by monitoring the user sessions and application sessions in progress. User sessions and application sessions are always associated with a user identity and a user profile. The user identity is the unique authenticated identity of the user. The user profile is the SGD user profile object that contains the user's settings.
User Sessions and Application Sessions describes the differences between user sessions and application sessions and how to use the Administration Console and the command line to monitor sessions.
