Diagnosing problems with the automated domain name registration application (ADNR)

The automated domain name registration (ADNR) application is a function that dynamically updates name servers with information about sysplex resources in near real time. The DNS names managed by ADNR can be names that represent all instances of an application within the sysplex, names that represent a specific instance of an application within the sysplex, names that represent the entire sysplex, or names that represent individual systems within the sysplex. ADNR communicates with the z/OS® Load Balancing Advisor, (specifically the Advisor application), which architecturally is a Global Workload Manager (GWM) according to the Server/Application State Protocol (SASP). The Advisor application from the z/OS Load Balancing Advisor is the only GWM with which ADNR is designed to interact. All references to a GWM in this topic see the Advisor application of the z/OS Load Balancing Advisor.
