Hi Tom, I understand your comments and have heard similar sentiments from some of our customers but in some ways things are the same as they were in previous versions of App-V whereby an unpublish never actually removed the app from cache, we just whitespaced it for overwrite. I guess its more obvious in App-V 5.
I have observed a situation where an App-v 5. Having reviewed the AppEnforce. As a coincendence i have noticed that some of the extracted.
So if the publish has failed due to some sort of sftmime command error i am yet to troubleshoot; these files won't be published into the client correctly. Therefore they won't appear fully streamed until the application is launched, which i can't do if the package hasn't been published.
That's an interesting issue Graham but the behaviour is exactly what I would expect if only an add had taken place, I explain add and publish in depth here: blogs. As you say, the question is why the publish is failing. The App-V event logs may also help you get an insight into what is going on with App-V too. Hi Thamim, If I have an application that I want to use across multiple sites and it requires different configuration files based on location under a certain directory on the local disk, can I just create 1 virtual app-v 5.
Is this also the way you can troubleshoot if you had missing files? Can you just manually copy files here to test? Hi Amal, you can have one package with multiple configurations however writing to the ProgramData location of the package is not an option as it is protected with read only access, the most you can do is copy files out of the location.
Group Policy would achieve what you want but the file would have to be placed outside of the cache location, you could also use the DeploymentConfig. I realize this is an old thread yet hope I might get a response. Hi Thamim,I want to understand whether an user or an admin has privileges to modify the content of root and VFS folder.
If i want to make any changes to any particular file that i have already sequenced can i directly go inside programdata-root ,vfs and edit them? App-V packages will have different permissions when running depending on user privilege and whether the application tries to write to PVAD or VFS, as explained here: blogs.
Hello Thamim, We were wondering why the ability to set cache limits was removed for App-V 5. Parts of the cache appear to be behaving as your article describes and in other ways not. We deployed App-V 5. The sparse files are supposed to just be place holders, but the file system is seeing them as taking up the full amount of space.
At least half of the applications have been published, but never run. So the four applications that are fully streamed should be using up a maximum of 5GB. So on this sample machine it looks as though App-V 5. It is not clear to us what exactly is happening. However, we do know that when we were using App-V 4. App-V 5. Thank you for posting your various articles. They have really been a fantastic resource. Very interested in what you are seeing.
Could you confirm what tool you are using to inspect disk space or are you just using explorer? Also are you accounting for F0 of all the apps that have been delivered? Good morning Thamim, We are using a freeware tool called Disktective to profile disk use. I am reasonably confident that it simply uses the Windows API to look at space usage. That has two positives: it saved me from writing a Powershell script and it is looking at disk use the same way Windows is when Windows reports we are out of disk space.
I know that Disktective will report symlinks as the size of files or directories that they point to because it was reporting the All Users profile links back to the App-V cache under Windows 7 x64 and we know that no such profile exists. I am not accounting for the F0 space only because I am not aware of a way to determine how big that block actually is. I know about how large the applications that have fully streamed are when they are locally installed so that is what I am using for the expected file size.
Though, even adding in the F0 blocks for all the applications that have not been invoked I would not expect the cache to exceed 10GB. The In another computer lab that was running out of space I saw that the cache was 17GB and when I launched an application that had not been invoked and waited to see that it was fully streamed the cache size was still reporting 17GB.
I even closed and re-opened explorer to make sure it was not a refresh error; the cache size had not changed. So in checking another sample machine with the exact same image and same streaming applications as the last sample, I see that Windows Explorer reports that GB of space is used on disk. If I add the totals from Disktective and exclude all App-V cache locations including ones that use symlinks then the used space is Perhaps the 9GB is being held by the Windows swap space; it does not show up explicitly in the report while Windows Explorer reports that pagefile.
This computer has a couple more small applications fully streamed. When I add up the size of the fully streamed applications I come up with about 6GB without accounting for F0 for the other applications. Thank you for letting us throw all these numbers at you. These results are a bit different than the last time I dug around on a computer, but they are similarly confusing. Perhaps we have about 2GB of user data in the App-V cache so that added with the swap space that looks about right for the total disk space with the rest of the cache under Microsoft pointing back to the App-V directory.
However, the App-V directory itself still seems to be awfully large given the number of applications that are cached. Hi Mark, I have been unable to replicate this issue on my environment. I would recommend you get a support case logged with us so we can investigate this properly. What was formerly often referred to as the "Cache" is more accurately called the package store in v5. There is support for the legacy App-V 4. Can you share your Powershell Workflow? User assumes all risks. Logical thing that does not work either is the combination of both.
Like mentioned under the above link. I can lookup the PackageID's from the App-V console for an appllication, but this is no option when you wanna remove all those packages from a pc.
Cause then you will be busy forever. Then it is working as designed. Unpublishing will only be for the user's assets. Also bear in mind you can pipe PowerShell commands i. Could someone maybe explain why yesterday it gave no PackageID in return and therefor i could not remove the programdata, and now it does give a PackageID with the same commands. I would review the debug-logs for further investigation - it will most likely offer the best chance to dive into that.

After the file is copied, remember to enable and start the service again. Copy the Sftfs. Set the folder access permissions to Read-only for the group Everyone and to Full Control for administrators who will manage the cache file updates. Important You must put the FSD file in a location that has the responsiveness and reliability equal to locally attached storage performance, for example, a SAN.
FSD Required. Configures the client to operate in Read-Only mode. This ensures that the client will not try to stream updates to the package cache. Entry used to specify the path of the error log. Configure each RDS server in the farm to use the publishing server and to use publishing update when users log on. As users log on to the RDS servers, a publishing update cycle occurs and publishes all the applications for which their account is authorized.
These applications are run from the shared cache. Upgrade the package on the App-V server. Then, publish and stream the new version of the applications to the client on the staging computer so that they are fully loaded into cache.
Note Or, you can first stop and then disable the Application Virtualization service in the Services. After the file has been copied, remember to enable and start the service again. FSD, to distinguish the new version. This guarantees that each RDS server receives the updated copy of the cache when the App-Vclient drivers restart. Important You must restart the RDS servers in order to use the updated shared cache file.
In contrast, Windows XP does not support the use of symbolic links, and you must use junction points instead.
