Due to unavoidable limitations in the protocols, the BizTalk adapters for FTP, POP3 and MSMQ require Microsoft Clustering Services to achieve high availability and avoid the processing of duplicate messages. There are two drawbacks to this.
1. The complexity of configuring and maintaining Microsoft Clustering Services on the BizTalk nodes.
2. Microsoft Clustering Services cannot coexist with Windows Network Load Balancing (NLB).
Burch Technologies offers an alternative.
The BTS Monitor and Failover Service is a product that removes the need to cluster the BizTalk Server nodes whilst still achieving full redundancy. It works like this: A windows service monitors the primary node A and turns on the failover host (containing the FTP/POP3 receive locations) on Node B in case of failure on Node A. This windows service ensures that only one node is ever processing FTP/POP3 messages and ensures high availability in case of failure. Because this utility allows only one node to be active, the possibility of receiving duplicate messages is removed. This windows service runs actively on both nodes concurrently to provide high availability to the failover process.
In addition to the above mentioned protocols this component can provide HA for database (SQL Server or Oracle) receive locations which perform READ ONLY data extracts.
