FAQ: App-V: How to use the custom Exclusion List while Sequencing

Steps to create the custom exclusion list.

1. Launch the AppV sequencer.
2. Goto Tools -> Options
3. Select “Exclusion Items” tab
4. Add new exclusion items using “New Button”
5. When all the exclusion items are added then press “Save As Default” button
6. Copy the default.sprj file from “C:\Program Files\Microsoft Application Virtualization Sequencer\” or the folder where the sequencer was installed to some network share from where it can be accessed later.

Using the custom exclusion list

1. Copy the saved default.sprj file to “C:\Program Files\Microsoft Application Virtualization Sequencer\” before launching the Sequencer.
2. When launched the sequencer will take the exclusion list from the default.sft file.

FAQ: MAV: Removing the Servers from the Softgrid Management consoles.

Delete / rename the SftMMC which is located at “%appdata%\Microsoft\MMC” directory will remove all the settings and sever details also from the Softgrid Management Consoles.

PitHole: softgrid – Not running apps while in Capture Mode

Following are the few of the reasons why one should execute the applications while in capture mode.

1. Applicataion initialization: Most of the applications initialize on there first lauch and it is a good idea to capture that, Applications can do that by many ways such as self healing, etc

2. Component evaluating: This is something Sequencer does, it scans all the files and there working and based on that it sets the softricity attributes to the files and folders,

Microsoft Application Virtualization: Tips to pick right apps for sequencing

The following guidelines can be applied to test if any given application is a good candidate for sequencing or not.

1. Application Size: If the maximum client cache size is set for 4 GB (The Max can be 64 GB), then the maximum size of application (sft file) which can be streamed on that machine is 4 GB.

All applications which have the installed footprint greater then or equal to the max client size, set by the client, should not be sequenced. The Max applicaiton size Softgrid can handle is 4GB, [This is my guess as Q: drive has FAT filetype and the max filesize FAT can handle is 4GB ] {NEEDS to be verified by Microsoft.} More details at http://www.softgridguru.com/viewtopic.php?t=2763.

2. Device Driver: Softgrid presently do not support sequencing of device drivers thus any application which install device driver should not be sequenced.
   The only exception is when the device driver can be installed locally without installing the application. In this case the Device driver should be installed locally and only the application without the device driver should be sequenced.

3. Shortcuts: Application should have minimum of 1 Shortcut. If no shortcuts are present then the application should be sequenced in a Suite along with the application which needs it.
   If Macromedia Flash is the application in question to be sequenced then the shortcut should be pointing to the locally installed IE.

4. Middleware: Middleware applications are not a good candidate for sequencing as they can be used as prerequisites by various many applications in the build and thus should be installed locally. but if multiple version of it are needed then it should be sequenced along with the application which needs them.

5. Path hard coding: The application should not have folder/file path hard coded in the application itself. Some application hard code the path of files in registry or ini file or executables.

In these cases it has been found that the application can be sequenced most of the time, but extreme care should be taken while sequencing & testing. Configuration files such as ini, conf, txt etc are good places to look for the hardcoding.

6. Base Build Applications: Applications which are already part of base build should not be sequenced. One can sequence them but they are of no real value.

7. Auto Update: Application with automatic updates should not be sequenced. Sequenced application most of the time fails to properly update itself. Also allowing auto update leads to non compliance of application version.

Application should be sequenced only if the auto update feature can be disabled during sequencing procedure.

8. Services: For services -item, you should note that services that can be started when application starts and shut down when application main executable shuts down can be included in sequence. Only services that run as their own are (like boot-time services do but there are others) not suitable for sequencing since under SoftGrid all application starting happens under user’s session context. Special thanks to ksaunam.
   

9. COM+: Some application which uses COM+ might not work properly in virtual environment, thus this type of applications needs be tested properly.

10. COM DLL: Few application which uses COM DLL surrogate virtualization, i.e. DLL’s that run in Dllhost.exe, does not work properly in Softgrid Environment. Thus this type of applications needs be tested properly.

11. Licensing Policies: Applications with licensing enforcement tied to machine, e.g. the license is tied to the system’s MAC address. This type of application should not be sequenced if the activation can not be done by the user at the first launch of sequenced application.

12. Internet Explorer & Service Packs: Internet Explorer, Services Patch and Service pack can not be sequenced.
13. Hosts file can not be sequenced
    

Softgrid Helper Ver: 0.02 Released.

Hello All,

Today I am releasing a newer & better version of the Softgrid Helper.

New Features:
1. New Installer: The msi package has been created using War Setup which internally uses Microsoft WIX.
2. Logging Enabled: Now most of the task has been logged so that any issue can be debugged.
3. New Name & Icons: New icons make this application look better.

Bug Fix(es) :
1. Refresh All and clean up issues have been resolved.

The installer can be downloaded from Here

Thanks and Regards,
Mayank Johri

Note:
1. This software is should not be used in production and has not been tested at all.
2. This software has been released under GNU 3.0 License.

This is my second tool which i use to clean up the OSD files, and prepare them to promote them to production server by updating the server name in the OSD files by right clicking them and selecting “update to Prod Server” in Windows Explorer.

The tool can be downloaded from OSD Helper
The source code of the package is also available with the package and is released under GNU 3 License.

NOTE: This program has not been tested fully and will contain many bugs, kindly report them and this program has not been intended to be used in production. Use it at your own risk.

Also comments and suggestions are always welcome.
