How to configure the WebLogic AdminServer for High Availability

Introduction

The high availability of applications in the WebLogic environment is realized by clustering. Managed servers in the cluster work together. The information about transactions is distributed cluster-wide. If a cluster member fails, another server takes over the tasks of the failed server and executes them. In this way, the applications are kept running without interruption.

The AdminServer is a single point of failure: if the server fails, the Domain is no longer administrable:

– Configuration changes cannot be performed

– The administration console is not available

The managed servers are still running and can continue to work, even if the AdminServer is not available: this requires the activation of MSI (Managed Server Independence) Mode.

How can the AdminSevrer be protected from failure? In this blogpost I will describe all the steps that are necessary to keep your server running safely.

Changing listening address in Weblogic 12.2.1 with OWSM

Blog entry from my Colleague Grzegorz about the changing the listening address in WLS with OWSM

The Big Bang Tech

Changing the listening port and address may be more complicated than just updating the settings in WebLogic Administration Console. The reason for this is the fact that Cross-Component Wiring for Auto-Discovery of Policy Manager is used.

„Wiring is simply a piece of configuration in one component that points to another component, such as a URL that points to the admin interface of a component. With cross-component wiring:

  • Service providers publish their endpoints to a Service Table. These endpoints can be published automatically, such as when you create or extend a domain using the Configuration Wizard, or can be published manually by the administrator.
  • Clients contain configuration that points to the service (for example, it has the service URL). The client is „bound“ to the service by updating this configuration with the service information that was published to the Service Table. Binding is performed automatically when creating or extending a domain…
