语法

声明
<SharePointPermissionAttribute(SecurityAction.Demand, ObjectModel:=True)> _
<SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel:=True)> _
Public Class LobSystemInstance
    Inherits AccessControlledMetadataObject
用法
Dim instance As LobSystemInstance

[SharePointPermissionAttribute(SecurityAction.Demand, ObjectModel=true)] 
[SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel=true)] 
public class LobSystemInstance : AccessControlledMetadataObject

备注

The LobSystemInstance object allows you to associate multiple system instance-specific data such as connection parameters and authentication settings with a single system definition. The current release of Business Data Catalog allows supporting two LobSystemInstances for each LobSystem. One of them is used by web clients and the other by the Search crawler, since often these two Business Data Catalog applications require dissimilar authentication modes. Business Data Catalog disambiguates which one is used by the search crawler by tagging it with the UseForSearch property.
