Segments & Resources Panel

This panel allows both to see the tree of segments and resources from the configuration database as well as to disable and enable segments and resources or complete sub-trees. The tree can be expanded and collapsed by clicking on the different tree nodes.


Each tree node shows an icon for the corresponding database object

for segments
for resources

together with its name and its current status:

enabled
The segment or resource is enabled
enabled The resource is enabled but has disabled children
disabled
The segment or resource is disabled
disabled
The segment or resource is disabled as a result of one of the parent nodes being disabled or of one related disabled resource, and is no longer considered in the run control tree. The reason why the resource is disabled can be found by pressing the middle mouse button with the mouse pointer on the segment or resource (or waiting for a tooltip). You can still change the status of the node.

Enabling/Disabling segments and resources

If the Igui is not running in status display mode then you can disable or enable a segment or resource in the tree. Disabling a segment or a resource means that the segment or resource is no longer taken into account for the control and display of the Online Software.

If the enabled status of a segment or resource is changed then the changes are committed to the Remote Database server (RDB) and written to the database file so that other users of the database have the updated information. There are two steps to change the enable status: first changing the status of the node and then submitting it to the database server.

Changing the status of a node (segment/resource)

Pressing the right mouse button with the mouse pointer on top of a node shows the menu of the allowed changes for the node. Depending on the status (enabled/disabled) of the node you can disable/enable it. If a node is disabled then the whole corresponding sub-tree will no longer be taken into account by the Online Software regardless of the status of the sub-tree nodes.

If the status of a node is modified then the node will be marked by the a "difference to database" icon meaning that the component status in the panel is different from the one in the database and the database server. A box at the bottom of the panel informs the user whenever there are changes that have not yet been committed to the database server. Moreover every time the user tries to change to a different window then it will be reminded of the not yet done update.

Committing the changes to the database

By pressing the "Commit & Reload" button on the Igui toolbar the changes are committed to the database server, then written to the database file and the database will be reloaded so that the information of the Igui will be updated. The user can see the different steps as ERS messages in the ERS message window of the Igui. The Igui will notify the user in case of problems when committing and saving the changes.

Panel toolbar

The toolbar allows the user to show this help and shows also a warning message whether the status of one or more segments or resources has been changed without committing the changes to the database.
