Scenario instance and DataView item ownership
Scenario instances and DataView items in a correlator include an attribute identifying the owner of the instance. When a scenario instance is created through a dashboard, it provides the current user ID as the owner of the instance.
By default, you are only allowed to see and operate on those scenario instances and DataView items that you own, that is, the current user ID must match the apama.owner attribute of the instance or item. There are two exceptions to this default:
*If the owner is specified as "*", all users have access by default.
*SQL query attachments provide access for all users to all instances and items. See Using SQL-based instance tables form more information on SQL query attachments.
See Deploying and Managing Apama Applications for information on customizing access control.
