Help Migrating to XenAPP 5.0

Right now I have a Citrix Presentation 4.0 Enterprise Edition server farm all of which are 2003 servers. I will be create a new XenAPP 5.0 and have the following question and looking for advice from people who have been down this road already.

I plan on having two Zone so users in both physical office location can connect to their local xenapp farm instead of gong across the WAN also this help with fault tolernace. Each site will have their own license server asd well. how does this sound so far?

-I'm setting up my first xenapp license server and 2008 RDP license server now.

I can only go to xenapp 5.0 becuase some of app are old and 16-bit

I have read that Citrix does not recommend install applicatin directly on the server anymore but is pushing users to use App Steaming? Is this true?

has anyone had luck streaming 16 bit applications that use ntvdm.exe?

What does the XenApp plugin buy for me that I cannot get with the old Program Neighbohood?

Please help and advise

"I have read that Citrix does not recommend install applicatin directly on the server anymore but is pushing users to use App Steaming? Is this true?"

ABSOLUTELY NOT TRUE!  Most apps need to be installed locally on each XenApp server.  Some apps can be streamed but not all.

The old PN is no longer supported.  If you need to use that functionality use the new Quick Launch Tool.

XenApp plug-in is the new technology and is what will be supported and is also required to be installed in order to use the Quick Launch Tool.

Carl WebsterCommented:
An advantage of app streaming is being able to isolate apps from each other.

To isolate on a XenApp server you stream the app to the xenapp server.

I'm not the experienced with Citrix so please bare with me here..

I have read that Citrix / Xen has isolation zones you can setup ? How does this differ from APP Streamming?
0
 
Carl WebsterCommented:
Never heard of an isolation zone unless you are talking about application silos.  An application silo is simply one or more XenAPp servers that run a specific app or apps.

Let me refrase my quesiton..

Is there anyway for me to isolate installed application on a XEN server without using stream so each programs DLL's don't interfer withone an other??

0
 
Carl WebsterCommented:
Not that I am aware of since Application Isolation Environments have been removed from XenApp.

Just a note, XEN server is used to refer to the XenServer product which is Server Virtualization vs XenApp which is Application Virtualization.

This isn't good.. Then if I have t install all of my apps right onto my XenApp server all of them are going to fight with one other just want is happenin g my 4.0 enviroment now... :-(

Why did Citrix remove siloing??
Is there any other suggestion you have please help

Carl WebsterCommented:
Citrix did not remove siloing, just the Application Isolation Environment.

What is the difference betweeen the two?

I'm very new to Citrix still

Carl WebsterCommented:
An application silo is simply a XenApp server that runs a specific application or set of applications.

The old Application Isolation Environment was a special area that was created to hold an isolated application.  It was slow to run and cumbersome to update.  Very few people used it and Citrix and the industry moved to application profiling/streaming/sequencing.

Are there any good book that you know of that go in to detail about XENAPP streaming and siloing

BTW... can 16 bit applicatin be streamed..

I tried to stream an app but keep get NTVDM.EXE errors when I tried to run it though Citrix
0
 
Carl WebsterCommented:
I have no idea.  I don't have any customers that want to stream apps.

compdigit44Author Commented:
You seem to have experience with Citrix would you recommend trying to stream 16 or 32 bit apps..

Like MS Office Products, Adobe, etc..

Very confused.. I trying to setup a XenAPP farm and have 0 experience doing so

Carl WebsterCommented:
I would recommend installing the apps directly on the server.  ONly stream apps when required as is can be a lot of trouble.

CarlWebster - In XENAPP if I install the app directly on the server how can I isolate them from one another. Right now som of my applicatin in the Citrix farm conflict with one another
0
 
Carl WebsterCommented:
Install the apps on separate servers.  Or, create you a profiler server and learn to profile and stream apps.

Thanks for the help everyone..

BTW, is Feature PAck 3 the latest feature pack out for 5.0 also since I still have 16-bit apps, migrating to XenApp 5.0 is my only choice since 6.0 is 64-bit??

Correct???
0
 
Carl WebsterCommented:
Yes, Feature Pack 3 is the latest for XenApp 5.

Should I create a new domain user account that has local admin rights on my Citrix server and use this account as the Citrx account ??
0
 
Carl WebsterCommented:
If you mean for a Full Farm Administrator, that would be a good idea.

compdigit44Author Commented:
