FIX: A process operation on a cube may stop responding if the cube contains a ROLAP partition that is enabled for real-time updates in Analysis Services (888504)


The information in this article applies to:

  • Microsoft SQL Server 2000 Analysis Services
  • Microsoft SQL Server 2000 Analysis Services 64 bit

SYMPTOMS

In Microsoft SQL Server 2000 Analysis Services, a process operation on a cube may stop responding (hang) if the cube contains a ROLAP partition that is enabled for real-time updates. Additionally, when you try to connect to the Analysis server that has the database that contains the real-time enabled cube, one of the following symptoms occurs depending on how your client application is designed:
  • The connection process times out.
  • Your client application may stop responding.

CAUSE

This problem occurs because of a thread deadlock condition. Analysis Services uses a special SQL Server trace to monitor updates to the source tables of a cube that contains a real-time enabled partition. Analysis Services may receive an update notification from SQL Server at the same time that an Analysis Services thread makes a commit request for a process operation on the cube that contains a real-time enabled partition. When this behavior occurs, the real-time notification handler thread may enter into a deadlock with the thread that is trying to commit the process operation.
