Bug #: 50002171 (SQL Hotfix)
Microsoft distributes Microsoft SQL Server 2005 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 2005 fix release.
SYMPTOMS
In Microsoft SQL Server 2005, you open the Processors page in the Server Properties dialog box in SQL Server Management Studio. However, this page does not correctly report the processor affinity for an instance of SQL Server that is installed on a computer that has more than 32 processors. In the dialog box, the processor affinity shows that the affinity64 mask option has the same value as the affinity mask option regardless of the value that you set for the affinity64 mask option. When you run the sp_configure stored procedure to examine the processor affinity, the values of the affinity mask option and the affinity64 mask option are reported correctly.
For example, consider the following scenario:
- You install SQL Server 2005 on a computer that has 64 processors.
- You set the affinity mask option by using the sp_configure stored procedure to assign the first 10 processors to the instance.
Note The first 10 processors are shown as CPU0 to CPU9 in the Processors page in the Server Properties dialog box.
- You also use the sp_configure stored procedure to set the affinity64 mask option to 0. Therefore, the last 32 processors (CPU32 to CPU63) are not assigned to the instance.
In this scenario, when you examine the processor affinity in the Processors page in the Server Properties dialog box in SQL Server Management Studio, you will find that processors CPU0 to CPU9 and processors CPU32 to CPU41 are all incorrectly assigned to the instance.
