Reinstalling MS DTC After Installing Microsoft SQL Server™

Whenever you install SQL Server 6.5, SQL Server 7.0, or any SQL Server 6.5 or SQL Server 7.0 SP release, you must reinstall MS DTC. This reinstallation is necessary because SQL Server Setup installs an obsolete version of MS DTC that is incompatible with Component Services on Windows 2000.

? To reinstall MS DTC on a non-clustered system

1. Stop the MS DTC service. Also stop any services that depend on MS DTC, including Component Services, Microsoft SQL Server, Microsoft Message Queuing, and Microsoft COMTI.

2. Execute the Dtcsetup.exe program, which is located in the System32 folder.

3. Restart any services that depend on MS DTC.

? To reinstall MS DTC on a cluster with an existing MS DTC cluster

1. Use the MSCS Cluster Administrator to stop the MS DTC cluster resource. Also stop any services that depend on MS DTC, including Component Services, Microsoft SQL Server, Microsoft Message Queuing, and Microsoft COMTI.

2. Execute the Dtcsetup.exe program, which is located in the System32 folder, on the node that controls the MS DTC cluster resource. When you are prompted to install MS DTC on the other nodes in the cluster, run Dtcsetup.exe on those nodes.

Do not restart any system until MS DTC Setup has been successfully run on all systems in the cluster.

3. Restart all systems and also any services that depend upon MS DTC.

MS DTC Does Not Support

Rolling Upgrades on MSCS Clusters

MS DTC does not support rolling upgrades on MSCS clusters. When you install MS DTC on a cluster, you must do the following:

1. Stop MS DTC.

2. Upgrade MS DTC on all nodes in the cluster.

3. Restart MS DTC.

These steps are necessary because MS DTC maintains a single MS DTC log file for the entire cluster, and the new information has been added to the MS DTC log file for the Windows 2000 release.

In-Memory Database

After evaluating customer feedback from the Microsoft Windows 2000 Beta Program, Microsoft has determined that the In-Memory Database (IMDB) does not completely address the needs of most customer scenarios. The IMDB does not support query processing or stored procedures, and it requires customers to implement a different database access method.

The Transactional Shared Property Manager (TSPM), which was built on top of IMDB, has also been removed from Windows 2000. However, the Shared Property Manager technology that was initially released with MTS in Windows NT 4.0 is still available with Component Services in Windows 2000.

For additional information about IMDB, see the “What Happened to IMDB?” topic on the MSDN Web site at:

Removing COMTI Components with Component Services and Windows 2000

COMTI is a component of SNA Server 4.0 and later. When you remove a COMTI component from a Component Services application, it does not disappear from the COMTI Remote Environment pane. However, the component is removed from the COM+ Application Components pane. Although this produces an inconsistent display, you can deploy a new component with the same Class ID without causing an error.

Microsoft Data Access Components

Microsoft Data Access Components (MDAC) is automatically installed with Windows 2000. To obtain the most current information about MDAC 2.5 and known MDAC issues, see the MDAC release notes, which are installed at:

*system drive*:\Program Files\Common files\System\ADO
