Changing the Component Enabler

Before you upgrade a component configured with a previous version of TIBCO Silver Fabric Enabler for ActiveSpaces Enterprise Edition, it is good practice to back up your engines and to decide a time to restart the component.

• Make sure to understand the ActiveSpaces concepts of redistribution and recovering data from persisted stores. • If you restart your component instances individually, the data that is stored by the as-agent associated with each component instance is redistributed to the other running-as agents. • You can also shut down all of your component instances at the same time and allow them to recover their persisted data after you restart them.

To change the component enabler, follow these steps:

1.	Using the TIBCO Silver Fabric Administrator > Components page, identify the component you want to upgrade from a previous version of the TIBCO Silver Fabric Enabler for ActiveSpaces Enterprise Edition. Use the Enabler Version column to identify out-of-date enablers.

2.	Click the Component Action menu icon, select Change Enabler, select the appropriate version of the enabler and click OK.

3.	Click the Component Action menu icon again, click Publish Changes, and click OK to publish the selected component.

The component is not fully upgraded until you individually restart your component instances or stop and restart your stacks. For instructions on how to individually restart your component instances, see Individually Restarting Component Instances. For instructions on how to stop and restart your stack, see Stopping and Restarting All Component Instances.

Individually Restarting Component Instances

To restart each component instance, follow these steps:

1.	Switch to the Engines page, and click the Engine Actions menu for the component that needs a component restart.

2.	Select Restart Component.

Stopping and Restarting All Component Instances

To stop and restart all component instances, follow these steps:

1.	Use TIBCO Silver Fabric Administator to go the Stacks page and identify the stack running the component you want to stop.

2.	Click the Stack Action menu icon and select Stop Stack.

3.	Restart your stack using your regular start up procedure.
