Packages Installed Folder

[This product will work only on Windows NT 4.0 versions and earlier. For Windows 2000 and later, see COM+ (Component Services).]

The Packages Installed folder lists all the packages that you have added to a given computer. You can perform the following functions at the package level:

• Creating an Empty MTS Package
• Installing Pre-built MTS Packages
• Upgrading MTS Packages
• Setting MTS Package Properties
• Setting MTS Activation Properties
• Setting MTS Package Identity
• Enabling MTS Package Security
• Setting MTS Transaction Properties
• Locking Your MTS Package
• Exporting MTS Packages
• Monitoring Status and Properties in the MTS Explorer
• Using Property Sheets in the MTS Explorer

The Packages Installed folder also contains the following system packages:

System

Utilities

Note These are internal MTS packages, and generally should not be altered or configured by users. However, you may have to configure an internal MTS package in order to extend or restrict privileges for your MTS server. For example, to set up administrative privileges for a user on an MTS server, you add the user to the Administrator role for the System package.

You can install any number of packages in the Packages Installed folder. Each installed package contains the following subfolders.

• Components

Contains the components installed in the selected package

• Roles

Contains the roles assigned to the selected package.

Package properties can be configured using the following property sheets:

• General
• Security
• Advanced
• Identity
• Activation

If you are using MTS with Internet Information Server (IIS) version 4.0, the Packages Installed folder also contains the following IIS-specific system packages:

• IIS In-Process Applications

The IIS In-Process Applications folder contains the components for each Internet Information Server (IIS) application running in the IIS process. An IIS application can run in the IIS process or in a separate application process. If an IIS application is running in the IIS process, the IIS application will appear as a component in the IIS In-Process Applications folder. If the IIS application is running in an individual application process, the IIS application will appear as a separate package in the MTS Explorer hierarchy.

• IIS Utilities

The IIS Utilities Folder contains the ObjectContext component required to enable transactions in Active Server Pages (ASPs). For more information about transactional ASPs, see the Internet Information Server (IIS) documentation.

Microsoft Transaction Server uses the ObjectContext component for internal functions. You can view but not set this component’s properties.

Note When you create secure IIS applications that use process isolation, IIS creates an MTS package that is set to run as IWAM_<computer name>. If you wish to change the identity of these packages, you should also add the new package identity to the "MTS Impersonators" group or security will not work properly in other out-of-process MTS components called by your package. If this is not done, the caller will appear to be IWAM_<computer name> rather than the actual client of IIS.
