System Console

SysCon is the master node system console that starts automatically when startDOGMA is run (it may also be started manually using startSysCon.) SysCon consists of 2 windows - a text based window where a text-based system prompt resides, and a GUI window. Note that on Unix systems the text based window simply displays system output.

The GUI window has 5 panes as follows

Nodes Pane - Allows a quick view of nodes in the system, the load on these nodes, whether or not they accept remote objects, and other node information.  Clicking on a node brings up detailed information.  Nodes with their load bars darkened do not accept remote objects.

When a node is selected by clicking on its button, several buttons on the right side of the screen become active. They are:

Clusters Pane - Allows the viewing of clusters in the system, and which nodes are active in those clusters.  The clusters pane also allows nodes to be started and stopped as groups.

Code Servers Pane - Shows all known code servers as well as what packages are served up by the code servers.

Config Managers Pane - Currently unused.

System Pane - Allows the system to be shutdown.  Also provides a command prompt which can be used instead of the text based prompt.  This command prompt keeps a history of recently used commands.  There is also a list of commands that are currently executing.

The system prompt allows many of the above commands to be performed as well as applications to be run etc.  Type "help" at the system prompt for more information.
