disable-http-lb-server
|
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 a server or cluster managed by a load balancer.
Description
The disable-http-lb-server subcommand disables a standalone server or cluster of servers for load balancing. The disabled server instance or cluster goes offline for load balancing with a minimum impact to users.
Once the target has been disabled and the changes have been applied to the load balancer, the load balancer stops assigning new requests to the target. Session requests with sessions created before disabling the target continue to be assigned to that target until the timeout is reached. This process is known as quiescing.
Changes are applied the load balancer automatically. You can also manually export the configuration using export-http-lb-config and copy it to the load balancer.
