Changes needed to make to switch the URL from machine (host name) name to a DNS.
• Your systems people should create a DNS entry to point the IP address to a custom alias.
• If you are on UNIX open etc/host file to include the new host name.
• Go to weblogic admin page and change the PIA portal if needed.
• If the environment is already configured for machine name, go to Process Scheduler -> Report Nodes and change the machine name to new alias.
• Change the REN server configuration to reflect the new changes.
Important:
Even though you specify the new name for DNS, the REN server will default to the Actual machine name both in REN server definition and REN server Custer. So to overcome this issue you need to do the following.
1. Do not touch the REN server definition.
2. Go to REN Server cluster page and change the Cluster URL and Browser URL to new DNS name.
