22 Chapter 22. Migrating the User Name Server This chapter describes the process of migrating a User Name Server on AIX to WebSphere Message Broker V6.0 User Name Server on AIX. It guides you through the migration of the AIX User Name Server in the scenario described in Chapter 17, "WebSphere Business Integration Message Broker Version 5.0 environment setup" on page 313. The User Name Server is a component that authenticates users and groups performing publish/subscribe operations. It uses access control lists (ACLs) to enable control over the topics. The users can publish/subscribe to particular topics based on the security access provided to them. It requires WebSphere MQ queue manager, which can be shared with a Configuration Manager, a broker, or both in the broker domain. After you complete the steps in this chapter, the User Name Server will be ready to operate in the migrated domain. © Copyright IBM Corp. 2006. All rights reserved. 427
