业务流程引擎配置
业务流程引擎使用名为 BTSNTSvc.exe.config 的 XML 文件来确定特定行为。 例如，冻结属性及其默认值在 BTSNTSvc.exe.config 文件中配置为 XML，并会在所有包含业务流程的主机实例启动时进行读取。 有关详细信息，请参阅 业务流程解除冻结和解除冻结。
服务会在启动时读取一次此配置信息。 除非停止并重新启动该服务，否则不会读取对配置的任何更改。
有关不同的节点和可能的值，请参阅以下示例。

示例：AppDomain 配置
程序集是使用赋值规则分配给命名域的（详见下面的内容）。 如果没有为某个程序集指定规则，则会将该程序集分配给一个特别域。 为每个特别域分配的这种程序集的数目由 AssembliesPerDomain 的值来确定。

AppDomain configuration.
Assemblies are assigned to named domains using assignment rules (see more below). If no rule is specified for some assembly, the assembly will be assigned to an ad hoc domain. The number of such assigned assemblies per ad hoc domain is determined by the value of AssembliesPerDomain.

In this section the user may specify defualt configuration for any app domain created that does not have a named configuration associated with it (see AppDomainSpecs below)
SecondsEmptyBeforeShutdown is the number of seconds that an app domain is empty (that is, it does not contain any orchestrations) before being unloaded. Specify -1 to signal that an app domain should never unload, even when empty.
Similarly, SecondsIdleBeforeShutdown is the number of seconds that an app domain is idle (that is, it contains only dehydratable orchestrations) before being unloaded. Specify -1 to signal that an app domain should never unload when idle but not empty. When an idle but non-empty domain is shut down, all of the contained instances are dehydrated first.

<!--
The PatternAssignmentRules and ExactAssignmentRules control assignment of assemblies to app domains.
When a message arrives, the name of its corresponding orchestration's assembly is determined. Then, the assembly is assigned an app domain name. The rules guide this assignment. Exact rules are consulted first, in their order of definition, and then the pattern rules. The first match is used.
If no match is found, the assembly will be assigned to an ad-hoc domain. The configuration and number of assemblies per ad-hoc domain is controlled by the AssembliesPerDomain attribute and the DefaultSpec section.

- <ExactAssignmentRules>

<!--
An exact assembly rule specifies a strong assembly name and an app domain name. If the strong assembly name equals the rule's assembly name, it is assigned to the corresponding app domain.

<ExactAssignmentRule AssemblyName="AssemblyName_0" AppDomainName="AppDomainName_1" />

<PatternAssignmentRules>
<!--
<!--
A pattern assignment rule specifies a regular expression and an app domain name. If the strong assembly name matches the expression, it is assigned to the corresponding app domain. This allows version independent assignment, assignment by public key token, or assignment by the custom assembly key.

修改 BTSNTSvc.exe.config 文件的其他部分
有关修改 BTSNTSvc.exe.config 中的解除冻结值的信息，请参阅 解除冻结默认属性。
BTSNTSvc.exe 配置文件包含若干个其他部分，.NET Framework 常规参考中记载了这些部分。 有关修改这些部分的详细信息，请参阅 上.NET Framework常规参考的https://go.microsoft.com/FWLink/?LinkID=52964配置文件架构。
除了特定于 BizTalk 的配置信息，BTSNTSvc.exe.config 文件也是在业务流程、适配器或管道上下文中运行的 .NET 应用程序组件在运行时使用配置标记下<的标准 .NET appSettings 标记获取其配置>信息的位置。>< 由于 BizTalk 已经为自定义适配器和管道组件提供了一种机制来获取配置信息， <因此，BTSNTSvc.exe.config 文件中的 appSettings> 标记通常由从业务流程中调用的自定义 .NET 组件使用。 例如：
<appSettings>
<add key="configParamName" value="configParamValue" />
</appSettings>
基于业务流程阻止消息
此属性在 btsntsvc.exe.config 文件中指定，它通过限制业务流程可具有的未处理消息的数目，防止业务流程占用过多的内存。 所有邮件将继续传递到 MessageBox;但是，在业务流程处理一些未完成的消息之前，排队的消息不会传递到业务流程。
若要在位于BizTalk Server根目录) 的 btsntsvc.exe.config 文件 (指定此属性，请在“应用程序”节点下添加以下参数：
<configuration>
<application>
<Throttling PauseAt="100" ResumeAt="50" />
</application>
</configuration>
在此示例中，一旦业务流程具有 100 个未处理消息后，MessageBox 就将停止发送更多的消息。 在业务流程的未处理消息的数目下降到 50 后，它将指定 MessageBox 可继续发送消息。 您可以指定其他值。
您还必须在数据库中按每个主机启用此功能。 若要为主机启用消息阻止，您必须在 BizTalkMsgBoxDb 数据库中编辑 dbo.Applications 表。 对于要为每个业务流程启用消息限制的主机，请将 fAttributes 标志位设置为 1。 只有 fAttribute 设置为 1 的主机才允许每个业务流程的消息限制。
