Start a Host Instance

You can use the BizTalk Server Administration console or Windows Management Instrumentation (WMI) to start host instances. After you add or stop a host instance, you must start it so that it is running and routing messages to the MessageBox databases.

Important

The service account that you specify for a host instance should be a member of the Windows group for the associated host. Otherwise, the host instance may not have the appropriate permissions or authentication at run time. In addition, for security reasons, the account should have minimum privileges because orchestrations hosted by the host instance might execute potentially malicious custom code.

For more information about host instances, see Host Instances. For information about using WMI to start a host instance, see MSBTS_HostInstance (WMI) in the UI guidance and developers API namespace reference.

Prerequisites

To perform this procedure, you must be logged on as a member of the Administrators group and the BizTalk Server Administrators group.

In addition, you must also be a member of the db_securityadmin SQL Server Database role and the securityadmin SQL Server Role on the server(s) where the following databases are:

  • BAM Primary Import (BAMPrimaryImport)

  • BizTalk Management (BizTalkMgmtDb)

  • BizTalk MessageBox (BizTalkMsgBoxDb) (all)

  • BizTalk Tracking (BizTalk DTADb)

  • Rule Engine (BizTalkRuleEngineDb)

Caution

We recommend that you update account information for host instances by using the BizTalk Server Administration Console or a Windows Management Instrumentation (WMI) script. This ensures that BizTalk Server can update the account information in the BizTalk Server databases and keep the security configuration between the databases and host instance synchronized.

Steps

  1. Click Start, click All Programs, click Microsoft BizTalk Server 20xx, and then click BizTalk Server Administration.

  2. In the console tree, expand BizTalk Server Administration, expand the BizTalk group, click Platform Settings, and then click Host Instances.

  3. In the details pane, right-click the host instance you want to start, and then click Start.

    The status of the host instance changes to Start pending. After the host instance initiates, the status changes to Running.

    After you start a host instance, you can stop it to prevent it from routing messages to the MessageBox database. You must stop a host instance before you can remove BizTalk Server from a given computer. For information about stopping a host instance, see How to Stop a Host Instance.
