An application or service that queries information about a failover cluster by using the WMI provider may experience low performance or a time-out exception

View products that this article applies to.

Symptoms

Consider the following scenario:
  • An application or service uses the Windows Management Instrumentation (WMI) interfaces to query a failover cluster for the configuration and state information.
  • There are many resources and groups on the failover cluster.

In this scenario, the application or service may experience low performance or a time-out exception.

For example, if you use the System Center Virtual Machine Manager to manage a virtual machine on the failover cluster, you may experience this issue.

Cause

This problem occurs because the WMI provider responds to the query requests very slowly. The time that the WMI provider takes to complete the query requests affects the following performance measurements:

  • The ability and reliability of the service or application
  • The speed of generating a status report about the failover cluster
Therefore, a slow response of the WMI provider may cause the application or service to function abnormally.

Resolution

This hotfix optimizes the targeted WMI queries to the WMI provider of the failover cluster. This optimization is performed so that the common queries perform quicker when many resources and groups are configured on the failover cluster
