An environment has twenty dispatchers. The administrator wants to change one property to the same value for all dispatchers. How can that be…

IBM Cognos Administration utilizes a hierarchical object model where properties can be inherited from parent objects. To apply a uniform property change to a group of dispatchers, the standard administrative practice is to create a configuration folder and move the target dispatchers into it. By setting the desired property on the folder, all child objects (the dispatchers) within that folder will inherit the setting. This provides a single point of management and ensures consistency across the specified group of servers without affecting other components in the environment.

B. This is too general. While changing a property at the top-level configuration would affect all dispatchers, using a folder is the specific and correct method for managing a designated group.

C. This is incorrect. Manually changing each dispatcher is inefficient and error-prone. IBM Cognos provides inheritance and grouping mechanisms to facilitate bulk configuration changes.

D. The IBM Cognos Administration interface does not support selecting multiple dispatcher objects simultaneously to perform a bulk property edit; configuration is managed through the inheritance model.

1. IBM Cognos Analytics 11.0.x Documentation, Administration and Security Guide: In the section on Server Administration, it details the use of configuration folders. It states, "To apply the same configuration to a group of servers, you can create a configuration folder and add the servers to it. You can then set properties for the folder, and the servers in the folder will inherit those properties." This directly supports the method described in option A. (Reference: IBM Cognos Analytics 11.0.x, Administration and Security Guide, Chapter: "Server Administration", Section: "Set properties for server groups").

2. IBM Redbooks, IBM Cognos Business Intelligence V10.1: Intelligence Unleashed (SG24-7912-00): While for an earlier version, the architectural principle remains the same. Chapter 13, "Infrastructure Management," discusses the dispatcher and its configuration. It explains the hierarchical nature of configuration and the ability to group components to manage them collectively, stating that settings applied to a group or folder are inherited by its members. (Reference: IBM Redbooks SG24-7912-00, Chapter 13.2.2, "Dispatcher configuration," p. 531).
