Microsoft has added new features and changed others in WMI provider to BizTalk Server 2006.  These features include:

• add two new class MSBTS_SendHandler2 and MSBTS_TrackedMessageInstance2
• remove the MSBTS_ServiceInstance.ServiceInstanceID property
• change the definition (properties and methods) of 7 classes

I show below the complete list of changes:

MSBTS_GroupSetting Class

Properties

(+) BizTalkOperatorGroup: Gets the name of the BizTalk Administrator Microsoft® Windows® NT® Group

MSBTS_Host Class

Methods

(+) Cluster: Clusters all BizTalk Host Instances of the given BizTalk Host

(+) GetClusterResourceGroupNames: Returns List of cluster resource groups available

(+) UnCluster: Un-Clusters all BizTalk Host Instances of the given BizTalk Host

MSBTS_HostInstance Class

Properties

(+) ClusterInstanceType: This property tells whether the BizTalk Host Instance NT service is clustered

MSBTS_HostSetting Class

Properties

(+) ClusterResourceGroupName: When the host instances of this host are clustered, this property contains the cluster resource group name set by the Administrator

(+) DBQueueSizeThreshold: Maximum number of items in the Database

(+) DBSessionThreshold: Maximum number of DB Sessions (per CPU) allowed before throttling begins

(+) DeliveryQueueSize: Size of the in-memory Queue that the host maintains as a temporary placeholder for delivering messages

(+) GlobalMemoryThreshold: Maximum System-wide Virtual Memory (in percent) usage allowed before throttling begins

(+) InflightMessageThreshold: Maximum number of in-memory in-flight messages allowed before throttling Message Delivery begins

(+) IsHost32BitOnly: This property indicates whether the host instance process should be created as 32-bit on both 32-bit and 64-bit servers

(+) MessageDeliverySampleSpaceSize: This property indicates the number of samples that are used for determining the rate of the Message Delivery to all Service Classes of the Host

(+) MessageDeliverySampleSpaceWindow: Time-window (in milliseconds) beyond which samples will be deemed invalid for consideration

(+) MessageDeliveryOverdriveFactor: Percent factor by which the system will overdrive the Input rate for Message Delivery Throttling

(+) MessageDeliveryMaximumDelay: Maximum Delay (in milliseconds) imposed for Message Delivery Throttling. Zero indicates disable Message Delivery Throttling

(+) MessagePublishSampleSpaceSize: Number of samples that are used for determining the rate of the Message Publishing by the Service Classes

(+) MessagePublishSampleSpaceWindow: Time-window (in milliseconds) beyond which samples will be deemed invalid for consideration

(+) MessagePublishOverdriveFactor: Percent Factor by which the system will overdrive the Input rate

(+) MessagePublishMaximumDelay: Maximum Delay (in milliseconds) imposed for Message Publishing Throttling. Zero indicates disable Message Publishing Throttling

(+) ThreadPoolSize: Maximum number of messaging engine threads per CPU

(+) ThreadThreshold: Maximum number of threads in the process (per CPU) allowed before throttling begins

(+) ProcessMemoryThreshold: Maximum Process Memory (in percent) allowed before throttling begins

MSBTS_ReceiveLocation Class

Properties

(+) EncryptionCert: Contains the Name of the certificate used for outbound encryption

(+) SendPipeline: Represents the name of the pipeline that will process outbound documents

(+) SendPipelineData: Contains the custom configuration data for the SendPipeline

MSBTS_ReceivePort Class

Properties

(+) MSBTS_SendHandler2 Class

Properties

(+) AdapterName: Contains the name of the adapter used by the given instance

(+) CustomCfg: Contains adapter-specific configuration in XML format

(+) HostName: Contains the name of the BizTalk Host for this transport handler

(+) HostNameToSwitchTo: Contains the name of the BizTalk Host that this transport handler should switch to

(+) IsDefault: Indicates whether the send handler is the default one for this adapter type

MSBTS_SendPort Class

Properties

(+) OrderedDelivery: Determines whether the port should send messages in an ordered manner

(+) StopSendingOnFailure: Controls how EPM handles failures for order delivery enabled send port's primary transport

(+) RouteFailedMessage: Controls whether failed messages have to be routed to failed message subscribers

MSBTS_ServiceInstance Class

Properties

(-) ServiceInstanceID: Contains the ID of the service instance to which this message belongs

(+) MSBTS_TrackedMessageInstance2 Class

Properties

(+) MessageInstanceID: Contains the ID of the message

(+) PartCount: Number of message parts

(+) SourceDBName: Name of the SQL database where the tracked message is stored

(+) SourceDBServerName: Name of the SQL Server where the tracked message is stored

Methods

(+) SaveToFile: This method saves message context and parts into multiple output files

(+) this feature has been added
(-) this feature has been removed
