In Chapter 2, there is a section called "Registering a server node and remote information catalog." The section lists steps that you can complete from the DB2 Control Center before registering a remote information catalog using the Information Catalog Manager. The last paragraph of the section says that after completing a set of steps from the DB2 Control Center (add a system, add an instance, and add a database), you must shut down the Control Center before opening the Information Catalog Manager. That information is incorrect. It is not necessary to shut down the Control Center before opening the Information Catalog Manager.
The same correction also applies to the online help task "Registering a server node and remote information catalog", and the online help for the Register Server Node and Information Catalog window.
