General InformationThe main window is generally the first thing you see when you start the dashboard. It is divided into three sections:
Much of this is described on other pages. However, the following topics are important to your first use of the dashboard's main window and are discussed on this page: |

Initial Contents
You start the dashboard by giving it the database alias and schema name of a Q replication server. The first time you see the main window, it contains a live monitor for the schema's Q Capture and Q Apply programs as well as a list of subscribed tables that are known to this Q Capture and Q Apply. If only one of the programs is defined for the schema, then only one live monitor is displayed along with the subscribed tables known to the program.
The contents of the main window can be changed from you see initially. For example, you can change the window to show live monitors for all Q Capture and Q Apply programs associated with a specific subcription. You can also change the number of queues monitored in a given live monitor. See the Live Monitor and Subcribed Table pages for more information on how to make these changes.
Servers Accessed and Passwords UsedThe dashboard displays information it retreives from Q replication servers. To do so, it needs a user and password for each database alias it accesses. It needs these not only for the database alias you specify when you start the dashboard, but also for any database alias that contains a Q replication server that participates in a subscription with this server. Access to these other servers is required so the dashboard can provide status for subscribed tables. If you use the Replication Center, the dashboard retreives and uses those passwords. Otherwise, the first time the dashboard connects to a server, it prompts you for a user and password. The dashboard maintains user and password information internally. You can modify the information using the userid action available from the task bar. |

Refresh Interval
By default, the dashboard refreshes its information from Q replication servers every 20 seconds. You can change this value through the task bar. For example, you may want the dashboard to refresh more frequently if a live monitor is displaying information for a Q Capture or Q Apply program with a Monitor_Interval shorter than the dashboard's refresh interval.
Window Layout, Size, and PositionBy default, the main window displays Live Monitors above subscibed tables. You can change through the task bar so that the Live Monitors are on the left half of the window and subscribed tables are on the right. If you change the layout and then close and restart the dashboard, the dashboard uses the layout that was in use when it closed. The dashboard also remembers the size and position of the main window. If you change either the size or position and close the dashboard, the dashboard remembers its last size and position and set these the next time the dashboard is started. |
