The GUI allows users working on any machine to administer, operate or monitor servers and resources in any cluster as long as they have the required group memberships on the cluster machines. (For details, see Configuring GUI Users.) The GUI Server and Client components are described below.
The GUI server is initialized on each LifeKeeper for Windows server at system startup. It communicates with GUI clients using Hypertext Transfer Protocol (HTTP) and Remote Method Invocation (RMI).
The GUI client can be run either as a web client on any Java-enabled system or as an application on a LifeKeeper for Windows server.
The client includes the following components:
- The status table on the upper left displays the high level status of connected servers and their resources.
- The properties panel on the upper right displays detailed information about the most recently selected status table object.
- The output panel on the bottom displays command output.
- The message bar at the very bottom of the window displays processing status messages.
- The context (in the properties panel) and global toolbars provide fast access to frequently-used tasks.
- The context (popup) and global menus provide access to all tasks.
Starting the Application Client
Users with administrator privileges on a LifeKeeper for Windows server can run the application client from that server. Click Start, then point to All Programs, then SIOS->LifeKeeper->LifeKeeper (Admin Only).
If you have done this and the client still is not loading, see Network-Related Troubleshooting.
Exiting GUI Clients
Select Exit from the File Menu to disconnect from all servers and close the client.
