PTP/designs/rm extensions

The following sections detail some additional resource manager functionality that will be included in the 3.0 release of PTP.

Default Resource Manager Selection

The resource manager view has been enhanced to support the notion of a "default" resource manager. The default resource manager can be used by tools that require access to a particular remote system.

• Adds "Select Default Resource Manager" to current context menu (enabled if RM is running)
• The selected resource manager is annotated in the view
• RM selection listeners can be registered, and are notified when a new default RM is selected
• The method getSelected() returns null if no RM selected, otherwise returns selected RM
  • Default is no RM selected
• Stopping a selected resource manager fires a selection event (with null) and returns to the default
• The selected resource manager is persisted. When the resource manager is restarted:
  • It will be selected provided no other RM has been selected
  • The selection even will fire
  • If the RM fails to start due to an error, it will still remain the selected RM

Interfaces

RM selection interfaces are accessed from the PTPUIPlugin class by retrieving the RMManager.

Services Framework
