This expandable item provides the following options that allow you to specify the attributes with which you want to uniquely identify each object in the connected data system:
-
Available attributes. Lists the attributes that are available in the external data system. Use this list to select the attributes whose values you want to use to generate a unique identifier for each object in the external data system. You can filter attributes by typing in the text box at the top of this list. To select multiple attributes, hold down CTRL and click to select attributes in the list.
-
UniqueID attributes. Lists the attributes whose values are currently used to generate a unique identifier for each object in the external data system.
-
Add->. Moves the selected attributes from the Available attributes list to the UniqueID attributes list.
-
<-Remove. Moves the selected attributes from the UniqueID attributes list to the Available attributes list.
-
Constructed UniqueID. Displays a combination of the attributes whose values will make up a unique identifier for each object in the external data system.
This section describes how to create or modify a connection to an OLE DB-compliant relational database so that Synchronization Service could work with data in that database.
To create a connection to an OLE DB-compliant relational database, you need to use Synchronization Service in conjunction with a special connector called OLE DB Connector. This connector is included in the Synchronization Service package.
The OLE DB Connector supports the following features:
Table 68: Supported features
|
Bidirectional synchronization
Allows you to read and write data in the connected data system. |
No
By using this connector, you can only read data in the connected data system. |
|
Delta processing mode
Allows you to process only the data that has changed in the connected data system since the last synchronization operation, thereby reducing the overall synchronization operation time. |
No |
|
Password synchronization
Allows you to synchronize user passwords from an Active Directory domain to the connected data system. |
No |
In this section:
To create a new connection
In the Synchronization Service Administration Console, open the Connections tab.
Click Add connection, and then use the following options:
Connection name. Type a descriptive name for the connection.
Use the specified connector. Select OLE DB Connector.
Click Next.
Use the Connection string text box to type the connection parameters to access the OLE DB-compliant relational database. Alternatively, you can click the Configure button to specify the connection parameters by using a dialog box provided by Windows.
Click Next.
On the Specify how to select data page, use the following options:
Use data from this table. Allows you to select a database table that includes the data you want to participate in the synchronization operations. You can click Preview to preview the database table you have selected.
Use an SQL query to specify data. Allows you to compose an SQL query that provides a more flexible way for specifying data for synchronization. For example, you can use this option to specify multiple database tables.
Click Next.
On the Specify attributes to identify objects page, use the following options:
Available attributes. Lists the attributes that are available in the external data system. Use this list to select the attributes whose values you want to use to generate a unique identifier for each object in the external data system. You can filter attributes by typing in the text box at the top of this list. To select multiple attributes, hold down CTRL and click to select attributes in the list.
UniqueID attributes. Lists the attributes whose values are currently used to generate a unique identifier for each object in the external data system.
Add->. Moves the selected attributes from the Available attributes list to the UniqueID attributes list.
<-Remove. Moves the selected attributes from the UniqueID attributes list to the Available attributes list.
Constructed UniqueID. Displays a combination of the attributes whose values will make up a unique identifier for each object in the external data system.
Click Finish to create a connection to the OLE DB-compliant relational database.
To modify connection settings
- In the Synchronization Service Administration Console, open the Connections tab.
- Click Connection settings below the existing OLE DB-compliant relational database connection you want to modify.
- On the Connection Settings tab, click an appropriate item to expand it and use the options it provides.
You can expand the following items:
- See the next subsections for the descriptions of these items.
- When you are finished, click Save.
