Disabling or Enabling the Load Balancer for an Oracle Java Cloud Service Instance on OPCM
You can disable the load balancer for an Oracle Java Cloud Service instance to suspend the service instance during maintenance, or enable the load balancer to resume a service instance after maintenance.
When enabled, the load balancer forwards the requests it receives from clients to the Oracle WebLogic Server managed servers in your service instance. When disabled, the load balancer stops forwarding such requests, but instead responds with a maintenance message and the HTTP status code 503.
You cannot enable or disable the load balancer for a service instance while the service instance is being backed up.
To enable or disable the load balancer for a service instance:
From the Services page of the Oracle Java Cloud Service Console, click an existing service instance.
The Overview page is displayed.
Click Load Balancer.
Click the button that is available to change the status of the load balancer.
To disable a load balancer that is enabled, click Disable Traffic.
To enable a load balancer that is disabled, click Enable Traffic.
