How to Enable Administration Server High Availability in Fusion Middleware 12.2.x (Doc ID 2446662.1)

Last updated on JANUARY 18, 2024

Applies to:

Enterprise Manager for Fusion Middleware - Version to [Release 12c]
Information in this document applies to any platform.


The Oracle WebLogic Administration Server is a singleton application, so it cannot be deployed in an active-active configuration. By default, the Administration Server is only available on the first installed node, and for an SOA/Forms and Reports horizontal scale-out on local storage, it is available only on apphost1.domain. If this node became unavailable, then the Administration Server console and the Oracle Enterprise Manager Fusion Middleware Control would also be unavailable. This is an undesirable scenario. To avoid this scenario, the Administration Server and the applications deployed to it must be enabled for high availability.
