SYMPTOMS

When you restore a database backup in Microsoft SQL Server 2005 Analysis Services, you receive the following error message:
XML parsing failed at line n, column n: '>' expected.
. Errors in the metadata manager. An error occurred when instantiating a metadata object from the file, '\\?\Path.det.xml'
Additionally, the following event is logged in the Application log:

Event Source: MSSQLServerOLAPService
Event ID: 22
Description:
The description for Event ID ( 22 ) in Source ( MSSQLServerOLAPService ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details.

CAUSE

This issue occurs because the FileName.det.xml file is truncated when you create the database backup. When you create the database backup, Analysis Services obtains a list of the files to be backed up. Additionally, Analysis Services obtains the size of each file. The FileName.det.xml file contains the metadata for a cube and a list of the partitions for the cube. If a processing operation occurs after a backup operation is started, Analysis Services updates the FileName.det.xml file to include the name and the version number of the partition that is currently processing into the partition list. However, the size of the file in the list of the files to be backed up is not updated.

For example, the list of the files to be backed up that the server uses to create the database backup says that the FileName.det.xml file is 1,384 bytes. However, the FileName.det.xml file is actually 1,402 bytes because of the processing operation. The backup operation obtains only the first 1,384 bytes from the file. Therefore, the file that is stored in the database backup is not a well-formed XML document, and this problem occurs when you try to restore the database backup.
