When this program is executed, the window shown below, which is divided into four panes, will appear. Let's look at each pane briefly.
The four panes above are intended to give DBAs a variety of ways of visualizing the same databases and replication objects. For example, the "Map" pane provides a convenient way to check the replication gap at a glance, while "Replication Pairs" provides a convenient way of handling replication objects as pairs without having to think about the databases on which they are working. So, these four panes complement each other. For example, when a replication object is selected in the "DB Connections" pane, the same replication object is also selected in the "Replication Pairs" and "Map" panes. In addition, the properties of the selected replication object will be displayed in the "Properties" pane. In other words, the three editable panes, "DB Connections", "Replication Pairs", and "Map", interact multidirectionally with each other, while the read-only pane, "Properties", receives information from the other three panes.
The "DB Connections" pane offers the following features:
The "DB Connections" pane handles two types of objects: DB Connection and Replication Object.
DB Connection is a representation of an Altibase DBMS with specific user, typically "SYS". It has two state: disconnected and connected.
Once a DB Connection is in the connected, replication object may be shown up as children of the DB Connection. Replication Object is an object created with the CREATE REPLICATION statement. It forms a replication pair with a counterpart replication object, typically on another node.
The Replication Object icon in the pane shows the status of replication sender and receiver thread. Bottom left arrow in the icon represents sender thread's status, while top right arrow does receiver's thread. Green colored arrow means the replication object is working fine, while yellow colored arrow means it's stopped. Red colored arrow, applicable only to sender thread, presents "Retry" status which means the replication object's sender thread is trying to send XLOG but has been failed due to network problem or the corresponding replication object's receiver's problem.
The "Replication Pairs" pane offers the following features:
The two icons used at "Replication Pairs" pane are Replication Pairs and Replication Object. Replication Pair is a pair of corresponding replication objects having the same name, one residing on each of two different nodes. So, it doesn't carry any status but conveys the logical group of replication objects. Replication Object is the same as that of DB Connection pane.
The "Map" pane offers the following features:
The "Map" pane demonstrates DB Connections and Replication Objects with different shape icons for better understanding of their relcationship and status.
DB Connection icon at Map pane is the same as that at DB Connection pane except "Unknown" DB Connection. "Unknown" DB Connection will show up at Map pane if any replication object is unable to locate the corresponding replication object. So, it helps DBAs not to miss registering and openning required DB Connections.
On the other hand, Replication Object icon at Map pane is slightly different becuase it represents sender thread only, not receiver thread. Replication Object at Map pane depicts the sender's status - run, stopped, or retry - including replication gap status if DBAs specified warning and critical threshold values at the main menu, Window/Preference/Replication Manager/Gap Status.
