App-V 4.5 Streaming Server Configuration Registry Keys
****Note: This wiki is based on App-V 4.5. With App-V 5 the location of the registry settings has changed and the configurable options have also changed.
Location: HKEY_LOCAL_MACHINE\Software\Microsoft\Softgrid\4.5\DistributionServer\
Name |
Type |
Valid Range |
Default Value (hex/dec), additional info |
|---|---|---|---|
ConnectTimeoutSec |
Dword |
0 – 32,767 |
0000003c/60. The time that an inactive client connection is allowed to remain idle. In other words, how long it can stay connected without a session. |
CoreTimeoutSec- |
Dword |
0 –65,535 |
0000000a/10. How long the dispatcher should wait for a core process to accept a client connection. |
EnableAuthentication |
Dword |
0-1 |
1 - If enabled, all client connection requests are authenticated |
EnableAuthorization |
Dword |
0-1 |
1 - If enabled, all client streaming requests are authorized by comparing the client’s Windows credential with the ACL applied to the virtual application package |
FcBlockSizeKb |
Dword |
64-16383 |
00000200/512, must be < FcMaxSizeMb. 0 means file cache is disabled |
FcMaxSizeMb |
Dword |
128-16384 |
00000200/512, must be > FcBlockSizeKb. . 0 means file cache is disabled. The File Cache Maximum is the maximum amount of memory that each core process will allocate to stream files. Each client sessions uses at least File Cache Block Size while the file is streaming. When the client finishes streaming, the server eventually releases this memory. So a session can exist that is using no memory from the file cache. Additionally, each session may use more than the File Cache Block Size worth of file cache. The Metadata block in a sequencing may be very large (note that the Metadata block name is not related the server’s File Cache Block name) and the server always reads the entire block from the file before it sends it to the client (not a good idea). So if the server sees that a block in the sequencing is larger than the current File Cache Block Size, it will get more memory from the file cache and after it is done with the block shrink the file cache block back down the File Cache Block Size. So theoretically, the maximum number of clients a core process can support actively streaming is: (File Cache Maximum Size)/(File Cache Block Size) – (something for clients going over their File Cache Maximum Size). |
LogFile |
Reg_Sz |
|
C:\Program Files\Microsoft App Virt Streaming Server\logs\sft-server.log |
LogLevel |
Dword |
0 -5
|
3 (Warning) 0=transactions, 1=Fatal errors, 2=Errors, 3=Warnings, 4=Information, 5=Debug |
MaxConnections |
Dword |
1-32767 |
000003E8/1000 - Server can support ~500 connections per Core process. 0=unlimited connections |
NumCores |
Dword |
1-128 |
5 – The number of core processes that the dispatcher process should spawn on startup. The LWS is the maximum number of connections per core process. The HWS is the maximum number of connections for that instance of the SoftGrid system (that is the HWS divides the number of connections by the number of core processes) |
PackageRoot
|
Reg_SZ |
|
C:\Program Files\Microsoft App Virt Streaming Server\content\Server\content\ Absolute path to the root of the directory tree from which the server will read package files. |
PackageDetectionIntervalSec |
Dword |
0 – 2,147,483,647 |
00000708/1800. 0=package detection is disabled. Time between new package detection searches down the packageRoot, measured from the completion of the previous search. |
RtpTcpMinPort |
Dword |
1,025 – 65,535 |
0000c000/49152. Must be < RtpTcpMaxPort. Minimum TCP port number to use for client RTP and RTCP connections. |
RtpTcpMaxPort |
Dword |
1,025 – 65,535 |
0000ffff/65535. Must be > RtpTcpMinPort. - Maximum TCP port number to use for client RTP and RTCP connections |
RtspTimeoutSec- |
Dword |
1-60 |
0000003C/60. - timeout value for RTSP connections |
ThreadPoolSize |
Dword |
1-255 |
00000032/50 - – The size of the thread pool (i.e. the number of threads) used to process client requests. |
X509CertHash |
Reg_SZ |
|
No default value. – Identifies the certificate used for device authentication |
Version |
Reg_SZ |
