disable-http-lb-application

disables an application managed by a load balancer

Synopsis

disable-http-lb-application [--help] [--timeout 30]
 --name application_name target

Description

The disable disable-http-lb-application subcommand disables an application for load balancing. The disabled application goes offline for load balancing with minimal impact to users. Disabling an application gives a finer granularity of control than disabling a server instance and is most useful when a cluster is hosting multiple independent applications.

Once the application is disabled and the changes have been applied to the load balancer, new requests for the application are not forwarded to the target. Existing sessions continue to access the application until the timeout is reached. This process is known as quiescing.

If an application is deployed across multiple clusters, use this subcommand to disable it in one cluster while leaving it enabled in others.

If an application is deployed to a single server instance, use this subcommand to disable it in that instance while leaving the instance itself enabled.

Options

--help

-?

Operands

target

This operand specifies the server instance or cluster on which to disable the application. Valid values are:
