5.3 Preparing Your Environment for High Availability

Scaling out for high availability requires additional steps.

Table 5-3 lists tasks to perform if you want to scale out your standard installation environment for high availability.

Table 5-3 Tasks Required to Prepare Your Environment for High Availability

Task Description More Information

Scaling out to multiple host computers

To enable high availability, it is important to provide failover capabilities to another host computer. That way, if one computer goes down, your environment can continue to serve consumers of your deployed applications.

See Scaling Out a Topology (Machine Scaleout) in High Availability Guide.

Configuring high availability for Web Tier components.

If you added a Web Tier front-end, you must configure it for high availability and the WebLogic Server software.

See Configuring High Availability for Web Tier Components in High Availability Guide.

Setting up a front-end load balancer

You can use a load balancer to distribute requests across servers more evenly.

See Server Load Balancing in a High Availability Environment and Configure Load Balancer in High Availability Guide.

Configuring Node Manager

Node Manager enables you to start, shut down, and restart the Administration Server and Managed Servers from a remote location. This document assumes you have configured a per-domain Node Manager. See Node Manager documentation for more on advanced Node Manager configuration options and features.

See Administering Node Manager for Oracle WebLogic Server.
