Synopsis

[source,oac_no_warn]
----
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.


[NOTE]
=======================================================================

This subcommand is only applicable to Oracle GlassFish Server. This
subcommand is not applicable to GlassFish Server Open Source Edition.
