MSMQ Registry Settings (Compact 2013)

3/26/2014

Message Queuing (MSMQ) can be configured by setting registry information or by running the MSMQAdm utility.

Note

You must configure MSMQ after you set the computer name and current time.
The current time is used for generating the globally unique identifier (GUID). If the time is not set properly, more than one computer might be assigned the same GUID. For this reason, configuration does not proceed during the first cold boot. Instead, the user is responsible for the configuration.

Note

The default registry values vary depending on which catalog items are included in your Windows Embedded Compact OS design.

The following table describes the registry settings that you can change to configure MSMQ. These registry settings are located in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\SimpleClient.

Name	Type	Description	Default Value
AllowResponse	REG_SZ	Acknowledges the sender. MSMQ sends acknowledgements when the PROPID_M_ACKNOWLEDGE property is set. If the value is "No", MSMQ sends the acknowledgment using the host name, such as www.adatum.com. If the value is "Yes", MSMQ sends the acknowledgment using the IP address of the sender, such as 192.168.0.0.	Default setting is "No."
BaseDir	REG_SZ	Directory used for queue information and message storage.	Default setting is "\Temp\MSMQ."
BinaryEnabled	REG_SZ	Indicates whether MSMQ supports outgoing messages. If the value is "No", MSMQ receives incoming messages, but does not send outgoing messages. If the value is "Yes", MSMQ supports the native MSMQ and the SOAP protocol. Security Note: Setting the value to "No" can help improve security by allowing only specific types of messages. Note: For example, if MSMQ is used in a private network, you can set BinaryEnabled to "Yes" to support native MSMQ and SOAP-based protocols. Note: If MSMQ is used with the Internet, you can set BinaryEnabled to "No" and SrmpEnabled to "Yes" to support only SOAP-based protocol.	Default setting is "No."
CEStartAtBoot	REG_DWORD	Indicates whether MSMQ starts automatically when the device starts. Windows Embedded Compact-specific entry. If this value is 0, MSMQ will not start at boot time but can be started using the MSMQAdm utility.	Default value is 1.
CETrackNetwork	REG_SZ	You can set the value to "Yes" or "No." If the value is "Yes", MSMQ attempts to resend immediately after the network reconnects, instead of following the standard resend schedule.	Default value is "Yes."
DebugOutputChannels	REG_DWORD	Mask of the MSMQ debug output channels.	Default value is 2.
DebugOutputMask	REG_DWORD	Mask of the enabled debug zones.	Default value is 17.
DebugQueue	REG_SZ	Queue used to route debugging.	None.
DefaultLocalQuota	REG_DWORD	If this value is not present in the registry, the default incoming quota is 1024 kilobytes. Incoming queue quota, in kilobytes.	Default value is 1024.
DefaultQuota	DWORD	Queue quota, in kilobytes, for message storage by a remote queue. The maximum default queue size and the size of output queues are expressed in kilobytes.	Default setting is 256.
FSMaxTimeout	REG_DWORD	Time-out, in seconds, for an installable file system. If the MSMQ base directory is not found on startup, MSMQ waits for this period of time, rechecking every second before failing.	None.
HostName	REG_SZ	Host name to override the host name of the machine. If this value is not present in the registry, information is queried dynamically from the network.	Default is not set in the registry.
LanRetrySchedule	REG_DWORD	If there are no network interfaces, the next attempt to connect is shifted by this value, in seconds, instead of the retry schedule. If 0, the existence of network interfaces is not checked and the connection schedule is followed.	Default is not set in the registry.
LogSize	REG_DWORD	Size of the MSMQ log file.	Default value is 1000.
MachineQuota	REG_DWORD	Machine queue quota, in kilobytes. If this value is not present in the registry, the default machine quota is 2048 kilobytes.	Default value is 2048.
MessageID	REG_DWORD	Current message identifier, accurate within 1,000 messages. The MSMQ client sets this identifier for backup/restore purposes. We recommend that you do not change this value.	None.
OrderAckScale	REG_DWORD	Multiplier for transactional acknowledgement periods and time-outs.	Default value is 5.
OrderAckWindow	REG_DWORD	Number of packets sent per transactional queue until the transactional receipt arrives. We recommend that you do not change this value.	None.
OutFRSQueue	REG_SZ	Outgoing Falcon Routing Server (FRS) queue format name. This name must be a direct format name. If another name is used, you cannot configure the outgoing FRS queue.	None.
PingPort	REG_DWORD	Machine User Datagram Protocol (UDP) port that the MQPing service is monitoring. This ping port is set by the registration utility. Do not change the ping port setting.	Default value is 3527 set by the registration utility.
PingTimeout	REG_DWORD	Default is not set in the registry. Time-out for response to MQPing. If this value is 0, pinging is disabled and connections are attempted immediately.	None.
Port	REG_DWORD	Machine TCP/IP port that MSMQ is monitoring. This port is set to 1801 by the registration utility. Do not change the port setting.	Default value is 1801.
QueueManagerGUID	REG_BINARY	GUID of the queue manager, which is used for session protocols between Windows Embedded Compact implementations and Windows desktop implementations.	Default is not set in the registry.
RetrySchedule	REG_BINARY	Array of little-endian short (2-byte) values that provide the retry schedule of the time intervals for each subsequent attempt to connect to the server.	Default value is 300, 300, 600, 600, 900.
SrmpEnabled	REG_SZ	You can set the value to "Yes" or "No". If this value is "Yes", MSMQ supports the SOAP-based protocol. Security Note: Setting the value to "No" can help improve security by allowing only specific types of messages. Note: For example, if MSMQ is used in a private network, you can set BinaryEnabled to "Yes" to support native MSMQ and SOAP-based protocols. Note: If MSMQ is used on a web site, you can set BinaryEnabled to "No" and SrmpEnabled to "Yes" to support only SOAP-based protocol.	Default value is "No", which disables SOAP Reliable Messaging Protocol (SRMP).
UntrustedNetwork	REG_SZ	You can set the value to "Yes" or "No". Disables message routing. Security Note: This value can be used to help protect a device from connecting to untrusted networks.	Default setting is "Yes", which indicates that the current network is untrusted.

The following table describes the registry settings that you can change to handle dropped connections that can result from slow connections to wireless LANs.

Name	Type	Description	Default Value
ConnectionTimeout	REG_DWORD	Time-out, in seconds, for a connection to complete.	None.
IdleTimeout	REG_DWORD	Time interval, in seconds, before the connection closes because there is no incoming message.	Default value is 5 minutes.
MaxAckTimeout	REG_DWORD	Maximum negotiated time-out, in seconds, for receiving acknowledgement for session-level messages.	None.
MinAckTimeout	REG_DWORD	Minimum negotiated time-out, in seconds, for receiving acknowledgement for session-level messages.	None.
MinStoreAckTimeout	REG_DWORD	Minimum negotiated time-out, in seconds, for receiving acknowledgement for session-level messages before they are stored.	None.

The following table describes the registry settings that you can change to configure SRMP. These registry settings are located in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\SimpleClient\SRMP.

Value	Type	Description	Default value
MaxPost	REG_DWORD	Maximum size of the buffer, in bytes, that the ISAPI extension (SrmpIsapi) reads off the wire when processing SRMP messages over HTTP. Messages longer than the maximum value are rejected and a 413 status code ("Request Entity Too Large") is sent to the client.	Default value is 131072 bytes.
