Citrix Presentation Server 4.5 (previously codenamed “Project Ohio”) will be released soon. In this article, I’ll describe its new features.
In my mind, the most important thing about PS 4.5 is what it is not. Presentation Server 4.5 is NOT a major overall of PS 4. PS 4.5 has several new features—some of which are really cool—but none of which are architecturally significant or game changing. I think this is okay though.
In a much anticipated move, Citrix has made the Tech Preview (beta) version of MetaFrame Presentation Server 4.0 (MPS4) available to partners and iForum attendees. MPS4 contains most (if not all) of the cool new “future technologies” that were previewed at iForum last week.
I’ve started writing about some of the new features, and I’ll certainly write more as I work them out in my lab. In the meantime, I’d like to provide a quick “master list” of all the new features that are currently slated to be included in MPS4.
Server virtualization is the partitioning of a physical server into smaller virtual servers to help maximize your server resources. In server virtualization the resources of the server itself are hidden, or masked, from users, and software is used to divide the physical server into multiple virtual environments, called virtual or private servers. This is in contrast to dedicating one server to a single application or task.
Note: Hardware virtualization, which is also known as server virtualization or simply virtualization, is the abstraction of computing resources from the software that uses those resources.
Datastore:
Core data store changes make mixed farms incompatible because of differences between the structure of and communications to a XenApp 6 and a XenApp 5 data store. Consequently, mixed farms will most likely cause data store corruption.
XenApp 6.0 is not capable of contacting an IBM DB2 or Access database.
Management consoles:
The new MMC 3.0 Delivery Services Console only works with XenApp 6.0 and is a requirement – it does not work with XenApp 5.
In addition to all the great features available today, XenApp 6 has the following new features and enhancements:
Citrix Receiver The new Citrix Receiver for Windows supports eight languages with expanded support for plug-ins including Single sign-on, WAN acceleration, App-V and EasyCall. There is a new Dazzle-enabled Receiver for Mac. And for mobile devices, users can use Receiver on iPhone, Android or Windows Mobile to access applications hosted on XenApp 6
Upgrade: Installing a new version of a feature or realise item over an existing version.
Migration: A clean, new installation of that feature or realise item.
What’s that men ? Migration is time consuming because of:
(short version)
We have to create new Citrix farm We have to install new servers We are only able to migrate most Citrix Farm settings. (long version)
We have to create new Citrix Farm.
You can migrate the following XenApp object types.
Object Type Description Application All applications are enumerated; however, for the corresponding worker groupbe associated with the application, the application must be d to one of the servers specified in the server mapping file. hat can be resolved on the server in the new farm (account auth are trusted in the new farm) are migrated.When migratinApp 6.5 test/pilot farm, this includes pre-launched applicationsting from a 32-bit XenApp 5 platform, the application path is not translated.
While migrating from xenapp 5 to xenapp6 using powershell cmdlet, you might get the below error:
Exception calling “Open” with “1” argument(s): “Unable to connect to server: ‘Remote COM+ access is not enabled on the server. Goto the source server(xenapp5 server) and in application server role, install com+ network access role and try again. It will work.
The main sad thing in migrating older xenapp versions to xenapp 6.5 is, mixed farms are not supported in xenapp 6.0, 6.5 and there is no direct upgrade from older versions to 6.5. If you have presentation server 4.5 and you want to migrate to xenapp 6.5, we first need to upgrade to xenapp 5, and then to xenapp 6 and then to 6.5. There is no direct upgrade/migrate to xenapp 6.
Inorder to migrate all your settings, applications, policies etc from xenapp 5 to xenapp 6, we need to install xenapp migration tool from mycitrix.com first. Once downloaded and installed, perform the below steps to migrate all your settings, applications, policies etc.
1. On a XenApp 6 server, install the XenApp 6 Migration Tool
(Citrix.XenApp.Migration.Install_x64.msi), including the option to set the PowerShell execution policy to AllSigned
2. On the XenApp 6 server, access the tool via the Start->All Programs->Citrix->XenApp
