How do I define failover servers for delivery groups

Although XenApp 6.5 worker groups do not exist in XenApp 7.x, we’ve seen how similar functionality is available.

Instead of comparing XenApp 6.5 with XenApp 7.x, let’s put some of these new technologies into practice by solving the following design requirement.

  • Define a set of XenApp hosts as failover servers for a group of XenApp hosts delivering the primary app? In addition, the failover servers have the following conditions:
    • The failover servers are a subset of servers hosting their own set of apps
    • The failover servers only host the primary app in the event the primary hosts are unavailable

How do I increase Delivery Group (Worker Group) capacity

As described in the blog How do I migrate a XenApp worker group structure, we saw how the use of Delivery groups, application groups and tags allow us to replicate XenApp 6.5 worker group capabilities to XenApp 7.x. There are some operational differences between Worker Groups and Delivery Groups, namely, how do increase the capacity of the delivery/worker group.

One of the more interesting capabilities of XenApp 6.5 worker groups was in the ways an admin could increase worker group capacity.  By adding a server into a worker group, the capacity of the worker group increased.

Many organizations took this approach a step further by basing worker group membership on Active Directory group membership or Active Directory OU membership.  In the XenApp console, each worker group was assigned to a single Active Directory group or OU. Any server in the Active Directory group or OU would be a member of that worker group.

How do I migrate a XenApp worker group structure

In XenApp 6.5, there is the concept of a worker group.  Before that, we called them load managed groups or application silos.  Basically, it is  group of XenApp servers publishing the same set of applications.  If you publish an app on one server, that published app is also available across every other server in the worker group. In XenApp 7.x, you can think of a delivery group like a worker group.  A delivery group is associated to a machine catalog, which is a group of XenApp servers.  If I publish an app within the delivery group, all XenApp servers in … Continue reading How do I migrate a XenApp worker group structure

How Do I Create ICA Files

In older versions of XenApp (6.5 and earlier), we could create ICA files, which were essentially shortcuts, and email them to users or place them on a static web page. With XenApp 7.x, ICA files are no longer available.  However, StoreFront provides an alternative with a little option called “Website Shortcuts”. It is a feature I was unaware of until I needed it for a project. After you setup your environment with StoreFront servers, Delivery controllers and VDI resources, you do the following: Launch the StoreFront console Select “Stores” Select your store Select “Manage Receiver for Websites” Select “Configure” Select … Continue reading How Do I Create ICA Files

Hello, DNA

I love seeing crazy comparisons and statistics, especially if it has anything to do with science Deoxyribonucleic acid (DNA) If laid out end-to-end, all DNA within your body would go from the Earth to Pluto and back to the Earth (too bad Pluto is not a planet anymore.) Humans share 99% of their DNA with everyone else (makes the 7 degrees of separation game kind of pointless.) If you could type 60 words per minute, eight hours a day, it would take approximately 50 years to type the human genome (Well, I can type 61 words per minute). Humans have roughly … Continue reading Hello, DNA

Upgrading from XenApp 7.5 to XenApp 7.6

After delivering the XenApp 7.6 Upgrade webinar, I received a few questions asking if it is a good idea to upgrade from XenApp 7.5 to XenApp 7.6. My first reaction is, “Of course you should. Why wouldn’t you?” But I’m a little biased J You need to ask yourself if the new features within XenApp 7.6 are important enough to upgrade. Look at the following subset of features and determine if they are something that would be valuable for your users and admin: Unauthenticated Logons: This feature allows a user to access an application without being required to authenticate. This … Continue reading Upgrading from XenApp 7.5 to XenApp 7.6
