In IBM WebSphere environments, you can use the administrative console of the job manager or the deployment manager to delete a proxy server from managed targets. The steps involve choosing the "Delete proxy server" job, specifying the job targets (like a specific node name), naming the proxy server to delete (e.g., proxy_server_2 ), and scheduling the job. The job stops the proxy server, if running, and removes it from the flexible management environment. Additionally, the "Proxy server cluster member collection" page allows you to view and manage proxy cluster members, including the option to delete a member.
Removing a WAP node requires a specific sequence to prevent configuration sync errors across the remaining nodes and avoid external downtime. This article provides a comprehensive walkthrough for removing a WAP server from an Active Directory Federation Services (AD FS) connected cluster using both GUI and Windows PowerShell methods.

If your cluster sits behind a hardware or software load balancer (F5, AWS NLB, HAProxy), verify the health probe settings. Does the balancer use a simple TCP handshake, or does it probe a specific URL ( /wap/health )? Removing the node before updating the LB will cause traffic to route to a black hole.
Click or Disable Web Application Proxy from the actions menu.
To guarantee that your infrastructure remains stable and fully functional after the removal, perform the following validation checks:
You need local administrative rights on the proxy servers and Active Directory credentials to manage the server objects.
