Merge-Partition cmdlet

Merges the data of one or more source partitions into a target partition and then deletes the source partitions.

Merge-ASDatabase [-Name] <string> [-SourcePartitions] <System.String[]> -Database <string> -Cube <string> -MeasureGroup <string> [-Server <string>] [-Credentials <PSCredential>] [<CommonParameters>]

Merge-ASDatabase -TargetPartition <Microsoft.AnalysisServices.Partition> [-SourcePartitions] <System.String[]> -Database <string> -Cube <string> -MeasureGroup <string> [-Server <string>] [-Credentials <PSCredential>] [<CommonParameters>]

The Merge-Partition cmdlet merges the data of one or more source partitions into a target partition and then deletes the source partitions. Partitions can be merged only if they meet all the following criteria:

  • Partitions are in the same measure group.

  • Partitions are on the same computer.

  • Partitions share the same storage mode (MOLAP, HOLAP, and ROLAP for multidimensional databases).

For more information, see Configure HTTP Access to Analysis Services on Internet Information Services (IIS) 7.0 and Analysis Services PowerShell for HTTP connections.

If this parameter is specified, the username and password will be used to connect to the specified Analysis Server instance. If no credentials are specified default windows account of the user who is running the tool will be used.

To use this parameter, first create a PSCredential object using Get-Credential to specify the username and password (for example, $Cred=Get-Credential “adventure-works\bobh”. You can then pipe this object to the –Credential parameter (-Credential:$Cred).
