Getting Started with WebLogic Server: Basics on Setting Up Clusters and DNS Names (Doc ID 1575360.1)

Last updated on NOVEMBER 15, 2023

Applies to:

Oracle WebLogic Server - Version 10.3 and later
Information in this document applies to any platform.


A customer reports: "I'm confused about DNS names in a WebLogic environment.

For best results, we should use a load-balanced DNS name rather than specify each individual server name on a JNDI URL - it says that in various WLS documents.

So, in my environment, I have the following:

Adding Server1 and Server2 to a DNS name gives me mydnsname.domainname, and this will then load balance between Server1 and Server2 -- but I don't understand what happens to the port number in this configuration?

Using JNDI, I would have a URL of "Server1:port1,Server1:port2,Server2:port3,Server3:port4" How would that work using DNS, or have I totally confused myself?"
