activate

This action activates an activatable subworkspace. For the subworkspace of an item to be activatable, the superior item must include this configuration statement in its Item-configuration attribute:

declare properties as follows: activatable-subworkspace

When you start or restart a KB, G2 does not activate activatable subworkspaces: they remain inactive until they are activated with the activate action. For more information about the effects of activating a subworkspace, see How Activating and Deactivating Affects Items.

To activate a subworkspace:

activate the subworkspace of item

where item refers to:

Any object whose class definition includes the configuration statement in its Instance-configuration attribute.
Any item, capable of having a subworkspace, whose Item-configuration attribute includes the configuration statement.

Note: Disabling an activated subworkspace also deactivates it. Subsequently enabling the subworkspace leaves it deactivated.

When you activate a subworkspace, G2 invokes any initially rules residing upon the subworkspace and then starts scanning rules on the subworkspace after all initially rules are complete. You cannot activate a subworkspace if its superior object is:

Disabled (by selecting Disable from its menu)
On a workspace that has been disabled (by selecting Disable from the KB-Workspace menu)
On an inactive subworkspace

When you try to do so, G2 signals an error and does not activate the subworkspace.
