GUID Manager

The GUID Manager lets you change an application's GUID (global unique identifier). You can randomly generate a new GUID, manually specify a new GUID, or change the GUID to match another application's GUID. You might want to change an application's GUID for the following reasons:

• The Application object is accidentally deleted from Novell^® eDirectory^TM. When you re-create the Application object, it is randomly assigned a new, unique GUID. Because the new GUID will cause the application to be redistributed to all users and workstations associated with the application, you use the GUID Manager to change the new GUID to the old GUID.
• You have multiple Application objects for the same application to enable fault tolerance, site lists, and so forth. You want to make sure that all Application objects have the same GUID so that the application is distributed only one time regardless of the Application object that is used. You use the GUID Manager to synchronize the GUIDs.

Changing the GUID of an undistributed application has no redistribution consequences. However, before you change the GUID of a distributed application, be aware that doing so might result in Application Launcher redistributing the application. In particular, redistribution occurs in the following situations:

• You give the application a new, unique GUID (one that is different from all other applications' GUIDs). A new, unique GUID always results in redistribution.
• You give the application the same GUID as another application that is not distributed on the workstation. For example, App1 has GUID 1234 and App2 has GUID 5678. You synchronize App1 with App2 so that both applications now have 5678 as their GUID. Any workstations that had App1 but not App2 will now have App1 redistributed to it.

Applications to Receive New GUID
Use this list to specify the application, or applications, that will be assigned a new GUID. By default, the list displays the application that was selected when you opened the GUID Manager.

You can use the Add button () to add additional applications to the list. Depending on the GUID Source option you choose (see below), all applications are assigned the same GUID or each application receives its own randomly-generated GUID.

In addition to changing the application's GUID, the GUID Manager resets the application's version number to 0.

GUID Source
The GUID Source options let you specify how to create the new GUID, or GUIDs, for the applications listed in the Applications to Receive New GUID list.

Randomly Generate New GUID
Use this option to have the GUID Manager randomly generate a new GUID. If you have added multiple applications to the Applications to Receive New GUID list, choose from the following two options:

• All Selected Apps Share Same GUID: Assigns the same randomly-generated GUID to all of the applications.
• All Selected Apps Get New GUID: Assigns different randomly-generated GUIDs to each application.

Select GUID from Existing Application
Use this option to synchronize the GUIDs of all listed applications with an existing application. Click the Browse button to browse for and select the Application object whose GUID you want to share.

The source application's GUID (the one you select using this option) does not change. Only the GUIDs for the applications displayed in the Application to Receive New GUID list change.

Manually Specify New GUID
Use this option to define a specific GUID for all listed applications. Click Modify to display the Edit GUID dialog box used to define the GUID.
