To enable dynamic reconfiguration:
When creating a load balancer configuration, use the --reloadinterval option with asadmin create-http-lb .
This option sets the amount of time between checks for changes to the load balancer configuration file loadbalancer.xml. A value of 0 disables dynamic reconfiguration. By default, dynamic reconfiguration is enabled, with a reload interval of 60 seconds.
If you have previously disabled it, or to change the reload interval, use the asadmin set command.
After changing the reload interval, export the load balancer configuration file again and copy it to the web server’s config directory, then restart the web server.
If the load balancer encounters a hard disk read error while attempting reconfiguration, it uses the configuration that is currently in memory. The load balancer also ensures that the modified configuration data is compliant with the DTD before over writing the existing configuration.
If a disk read error is encountered, a warning message is logged to the web server’s error log file.
