Hosts and Host Instances

A host is a logical representation of a Microsoft Windows process that executes BizTalk Server artifacts such as send ports and orchestrations. A host instance is the physical representation of a host on a specific server. A host can be either an in-process host, which means it is owned and managed by BizTalk Server, or an isolated host, which means that the BizTalk Server code is running in a process that is not controlled by BizTalk Server. A good example of an isolated host is Internet Information Services (IIS), which hosts the receive functionality of the HTTP and SOAP adapters. Hosts are defined for an entire BizTalk Server group; a collection of BizTalk Servers that share configuration, MessageBoxes, ports, and so on.

Difference between an Isolated host and an In-Process host:

The difference between an Isolated host and an In-Process is that an Isolated host must run under another process, in most cases IIS, and an In-Process host is a complete BizTalk service alone. Additionally, since In-Process hosts exist outside of the BizTalk environment, the BizTalk Administration Tools are not able to determine the status of these hosts (stopped, started or starting).

Security is also fundamentally different in an Isolated host versus an In-Process host. In-Process hosts must run under an account that is within the In-Process host’s Windows group, and do not maintain security context within the Messagebox. Isolated hosts are useful when a service already exists that will be receiving messages either by some proprietary means or by some other transport protocol such as HTTP. In this case, the Isolated host only runs one instance of the End Point Manager, and is responsible for receiving messages from its transport protocol and sending them to the Messagebox through the EPM.

Configuring BizTalk WCF Timeout Values on a Binding

There are a number of timeout settings available in WCF bindings. Setting these timeout settings correctly can improve not only your service’s performance but also play a role in the usability and security of your service. The following timeouts are available on WCF bindings: OpenTimeout CloseTimeout SendTimeout ReceiveTimeout Open Timeout : This property represents the amount of time a channel open operation has to complete. Send Timeout : Use this property to set the amount of time that a send operation has to complete. When used as part of a solicit-response scenario, this value encompasses the total amount of time for the interaction to complete. If we are sending a large message, we may need to increase this timeout to allow for the request and response messages to be processed within this window. Close Timeout : A time-stamp that is used to indicate the amount Receive Timeout : Used by the Service Framework Layer to initialize the...
