PTP/designs/rm extensions

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

Resource Manager Selection

• Add "Select Resource Manager" to current context menu if RM is running
• The selected resource manager will be annotated in view
• RM selection listeners will be notified when an RM is selected
• The method getSelected() will return null if no RM selected, otherwise will return selected RM
• Default is no RM selected
• Stopping a selected resource manager will fire selection event (with null presumably) and return to the default
• The selected resource manager will be 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: PTPUIPlugin.getDefault().getRMManager()
