In a sysplex subplexing environment, there are some additional considerations for using ADNR. These steps are described in detail in the following subtopics.
Before you begin
Procedure
Perform the following steps to use ADNR in a sysplex subplexing environment.
- Plan how the new subdomains representing each subplex will fit into your DNS hierarchy.
- Configure the name servers that will be updated for the new subplex domains.
- Define and configure one Advisor per subplex.
- Update the Agent configuration files to communicate with the Advisor running in its subplex.
- Define one ADNR application per subplex.
- Assign the host_group and server_group statements from the sysplex ADNR configuration to their correct subplex domains.
- Configure the new ADNR instances to update the name server and zone for its subplex.
- Configure the new ADNR instances to communicate with the subplex Advisor.
- (Optional) Update resolver configuration files.
- Start the TCP/IP stacks, Advisor, Agent, ADNR, and target applications that ADNR will manage.
- Verify that each subplex ADNR is functioning correctly.
