In zero-downtime 24/7 environments with shift employees, customers rarely want users to be notified of scheduled or mandatory XenApp server reboots. As a result, most of these environments have reboots disabled or this process is done manually. Unfortunately, this isn’t a good process since the XenApp servers are susceptible to memory leaks which can lead to failure and poor performance. By utilizing the included Chained reboot scripts, environments can take advantage of N+1 overallocation by processing a single server reboot while maintaining the user load on remaining systems. This has been done in such a way that users are not kicked off the system for scheduled reboots. Instead, the server is removed from load balancing until all sessions have been logged off. Once all sessions have been logged off, the server will go down for a reboot.
