Changing Query Data Synchronization

The frequency that query data is synchronized is set in the Property Inspector for the Data Control (.cpx). There are two choices, batch and immediate:

Batch synchronization disconnects the client and middle tier. This requires far fewer network round trips and is thus more scalable and performant.
Immediate synchronization is for applications that have a very high level of interactivity with the database and/or where immediate validation is required.

Changing synchronization settings

Each client has its own default setting that can be changed.

To change a clients synchronization setting:

In the Navigator, click on a clients .cpx file.
In the Structure pane, click on the data control.
In the Property Inspector, click the Sync Mode property and choose the appropriate type from the dropdown list.

The .cpx file will be updated with the following <DataControl> element definition:

<Parameter name="Sync" value="Batch" or "Immediate" > </Parameter>

Note that if you edit the .cpx file yourself, type the value as "Batch" or "Immediate ". The values are case-sensitive.
