SYMPTOMS

Consider the following scenario:
  • In Microsoft SQL Server 2008 Analysis Services or in Microsoft SQL Server 2008 R2 Analysis Services, you run a Multidimensional Expressions (MDX) query against a database.
  • You perform a process update operation on a dimension in the database.
  • You set the Process Affected Objects processing setting to True for the process update operation.
In this scenario, the process update operation may fail, and you receive an error message that resembles the following:
File system error: The following error occurred while opening the file '<path>.agg.rigid.map'.

Errors in the OLAP storage engine: An error occurred while processing the indexes for the <partition name> partition of the <measure group name> measure group of the <cube name> cube from the <database name> database

WORKAROUND

To work around this issue, use one of the following methods.

Note Both methods may result in a decrease in performance.

Method 1

Disable partition indexing and reprocess the dimension. To disable partition indexing, set the IndexBuildEnabled server configuration property to 0. To do this, follow these steps:
  1. Open the server configuration file Msmdsrv.ini that is located in the following folder:
    C:\Program Files\Microsoft SQL Server\AS Server Instance folder\OLAP\Config
  2. Change the value of the IndexBuildEnabled setting to 0.

Method 2

To use this method, follow these steps:
  1. Delete partition indexes by issuing the following XMLA request on the cube that reports the error message:
    <Batch xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">

    <Process xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ddl2="http://schemas.microsoft.com/analysisservices/2003/engine/2" xmlns:ddl2_2="http://schemas.microsoft.com/analysisservices/2003/engine/2/2" xmlns:ddl100_100="http://schemas.microsoft.com/analysisservices/2008/engine/100/100" xmlns:ddl200="http://schemas.microsoft.com/analysisservices/2010/engine/200" xmlns:ddl200_200="http://schemas.microsoft.com/analysisservices/2010/engine/200/200">

    <Object>

    <DatabaseID>[Your Database ID]</DatabaseID>

    <CubeID>[Your Cube ID]</CubeID>

    </Object>

    <Type>ProcessClearIndexes</Type>

    <WriteBackTableCreation>UseExisting</WriteBackTableCreation>

    </Process>

    </Batch>
  2. Run a Process Index operation to rebuild the indexes.
