Microsoft distributes Microsoft SQL Server 2008 and Microsoft SQL Server 2008 R2 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 or SQL Server 2008 R2 fix release.

Symptoms

Consider the following scenario:

  • You install an instance of SQL Server 2008 or SQL Server 2008 R2 that is configured to use a case-sensitive collation.

  • You create a SQL Server performance condition alert that uses one of the counters in the following table:

    Object

    Counter

    SQLServer:Buffer Manager

    Buffer cache hit ratio

    SQLServer:Transactions

    Update conflict ratio

In this scenario, the alert is incorrectly raised.

Note This issue does not occur when the instance of SQL Server 2008 or SQL Server 2008 R2 is configured to use a collation that is not case-sensitive.

Cause

This issue occurs because a Transact-SQL statement in the msdb.dbo.sp_sqlagent_get_perf_counters system stored procedure uses an incorrect name to read the counter for the performance condition.

This system stored procedure tries to read the corresponding base counter by using an incorrect name for the counter. The incorrect name contains a letter that is the wrong letter case.
