disable-http-lb-server

Disables a sever or cluster managed by a load balancer

Synopsis

asadmin [asadmin-options] disable-http-lb-server [--help]
[--timeout 30]
target

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.

This subcommand is only applicable to Eclipse GlassFish. This subcommand is not applicable to Eclipse GlassFish.
