Using Windows Server Cluster to Provide High Availability for BizTalk Server Hosts
BizTalk Server 2006 provides functionality that allows you to configure a BizTalk host as a clustered resource within a Windows Server cluster group. Host cluster support is provided to support high availability for integrated BizTalk adapters that should not be run in multiple host instances simultaneously; such as the FTP receive handler or, under certain circumstances, the POP3 receive handler. Host cluster support is also provided to ensure transactional consistency for messages sent or received by the MSMQ adapter in scenarios that require that the MSMQ service is clustered.
Host clustering is only available with BizTalk Server 2006 Enterprise Edition.
Before you can cluster a BizTalk host you must have configured at least two BizTalk Servers in a BizTalk Server group as members of a Windows Server Cluster. For more information about configuring a Windows Server Cluster please see the Windows Server online help.
