disable-http-lb-application
This subcommand has been retained from Oracle GlassFish’s original integration with external load balancers, but it has no proper integration functionality in Payara Server. Hence, it is not intended to be used in any way. The documentation in this page may not be accurate. |
Disables an application managed by a load balancer.
Synopsis
asadmin [asadmin-options] disable-http-lb-application [--help]
[--timeout 30]
--name application_name target
Description
The 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.
