Synopsis

Description

Use the `apply` `http``-lb-changes` subcommand to apply the changes in the load balancer configuration to the physical load balancer. The load balancer must already exist. To create a physical load balancer, use the `create-http-lb` subcommand.

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

Context

The Load Balancer distributes the workload among multiple Oracle GlassFish Server instances , increasing the overall throughput of the system. The Load Balancer also enables requests to failover from one server instance to another. For HTTP session information to persist, configure HTTP session persistence.

Note:

The Load Balancer Plugin is only available with Oracle GlassFish Server, and is not available with GlassFish Server Open Source Edition. For GlassFish Server Open Source Edition, it is possible to use the `mod_jk` module to configure load balancing on the Apache HTTP server.

For more information about configuring load balancing with GlassFish Server, refer to the online help in the GlassFish Server Administration Console.
