## Creating a Load Balancer Configuration

Now return to interacting with the Application Server’s Domain Admin Server. You need a shell execution environment for this section.

### To Create an HTTP Load Balancer Configuration

1. Create a load balancer configuration called `MyLbConfig` targeted to the cluster FirstCluster:

   `asadmin create-http-lb-config --target FirstCluster MyLbConfig`

2. Enable the FirstCluster cluster and the clusterjsp application deployed in it for HTTP load balancing:

   `asadmin enable-http-lb-server FirstCluster`

   `asadmin enable-http-lb-application --name clusterjsp FirstCluster`

3. Create a health checker for the load balancer, which signals when an instance that goes down recovers.

   `asadmin create-http-health-checker --interval 10 --config MyLbConfig FirstCluster`

   The interval is the number of seconds the health checker waits between checks of an unhealthy instance.

4. Export the configuration to a file `loadbalancer.xml`.

   `asadmin export-http-lb-config --config MyLbConfig loadbalancer.xml`

5. Copy `loadbalancer.xml` to:

   web_server_install_dir`/https-`hostname`/config/loadbalancer.xml`
