SYMPTOMS

On a symmetric multiprocessor (SMP) computer that is running Microsoft SQL Server 2000, you may notice the following behavior in the Windows Performance Monitor when you perform multiple transactions on an instance of SQL Server 2000:
  • The values for the Active Transactions counter for the _Total instance of the SQL Server:Databases object are not correct. You may also notice that the values are very large and unrealistic.
  • The values for the Active Transactions counter for the instances that correspond to individual databases are correct.

WORKAROUND

If the counters that are mentioned in the "Symptoms" section are used by custom applications, you can use the following work around to resolve the problem:
  • Calculate the sum of the values for the Active Transactions counter for the instances that correspond to individual databases. This sum is the actual value of the Active Transactions counter for the _Total instance.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.

Steps to reproduce the behavior

To reproduce the behavior, follow these steps on an SMP computer that is running SQL Server:
  1. In SQL Query Analyzer, connect to an instance of SQL Server to open a query window, and then paste the following code in the query window:
    -- Transaction for the first connection
while (1=1)
begin
begin tran
update pubs..authors set au_id=au_id
rollback
end
  2. In SQL Query Analyzer, connect to the instance of SQL Server that is mentioned in step 1, and then paste the following code in the query window:
    -- Transaction for the second connection
while (1=1)
begin
begin tran
update Northwind..Categories set Description=Description
rollback
end
  3. In SQL Query Analyzer, connect to the instance of SQL Server that is mentioned in step 1, and then paste the following code in the query window:
    -- Transaction for the third connection
while (1=1)
begin
begin tran
update pubs..authors set au_id=au_id
update Northwind..Categories set Description=Description
rollback
end
  4. Run the code that is mentioned in step 1, in step 2, and in step 3.
  5. Add the required counters in the Windows Performance Monitor to view the values. To do this, follow these steps:
    1. Click Start, and then click Run.
    2. In the Open box, type perfmon, and then click OK.
    3. Right-click in the right pane of the Performance window, and then click Add Counters.
    4. In the Add Counters dialog box, select SQL Server:Databases from the Performance object list.
    5. Select the Active Transactions counter from the list of counters.
    6. Select the _Total, the Northwind, and the Pubs instances from the list of instances, and then click Add.
    7. In the Add Counters dialog box, click Close.
In the right pane of the Performance window, you may notice incorrect values in the Average box and in the Maximum box. You may also notice that the values are much larger than the sum of the Active Transactions counters for the individual database instances.
