备注
If specified, the FileGroup value must match one of the NamedFileGroup values from the application definition file (ADF) Database element.
If you update a FileGroup element, updating the application re-creates the subscription class to which it corresponds. Notification Services renames the existing tables for the subscription class by appending Old to the table names. Existing subscription table indexes are left unchanged. If you want to transfer data between the old and new subscription tables, it must be done manually. For more information, see 更新应用程序.
示例
The following example shows how to have Notification Services place the subscription class tables in the Secondary filegroup.
<FileGroup>Secondary</FileGroup>
