Xenapp Slow Logons Troubleshooting Part2

Chai published on 2022-11-30 included in XenApp 6.5 XenApp and XenDesktop 7.X

We call these metrics “The Five Ls”: Launches Logon Times Load Times Latency ChanneL (Yes, including Channels is cheating, but mnemonics are worth it!) In this blog post, we’ll discuss how the Five Ls impact the performance and delivery of your Citrix applications and what actions you should take to improve performance in those areas. Special thanks to Ken Avram who originally compiled this content! Wire data analysis can provide you with real-time information about “the 5 Ls.

Enable Maintenance Mode on XenApp 6.5 App Servers

Chai published on 2022-11-21 included in XenApp 6.5

Starting from XenApp/XenDesktop 7.x we have maintenance mode option on the Citrix app servers directly. We can turn on or off the maintenance mode on the servers which will only disable Citrix sessions on those servers. RDP connection will still work on the faulty app server. In XenApp 6.5 appcenter, we can only disable logons to the servers which will also disable RDP access to the server. Using load evaluator, we can come around this issue and disable only Citrix logins, while making sure that RDP still works.

Containers allow software developers to build, run and manage applications efficiently from one place. They allow you to easily create isolated environments so that you don’t accidentally kill or corrupt data. Containers give you the flexibility to run multiple apps side by side without worrying about conflict. Containers are not just for developers anymore. Learn more about containers in this article.
