Improvements: BizTalk receive location can recover from fault on other hosts if one host has problems

Applies to: BizTalk Server 2016 BranchBizTalk Server 2016 DeveloperBizTalk Server 2016 Enterprise

Improvement


Assumethat you use multiple BizTalk servers. When one host instance has a problem(for example, the certificate is corrupted or the disk space runs out on one ofthe servers), you may face a very long downtime period. In this situation, younotice that the receive location may be closed and other host instances may notbe able to continue receiving data although they do not have any problems.
 
Now, it is possible to configure receivelocations to recover from transient errors instead of completely disabled byBizTalk. On fault, receive locations will be disabled in the host where it isfaulted and BizTalk will attempt to recover it in certain configurableinterval. The receive location will continue running in other hosts. Thischange can be made by adding DWORD ReceiverFaultToleranceEnabled withvalue 1 at following locations:
 
  • For 64 bit BizTalk host instances: HKLM\SOFTWARE\Microsoft\BizTalk Server\3.0\Configuration
  • For 32 bit BizTalk host instances: HKLM\SOFTWARE\Wow6432Node\Microsoft\BizTalk Server\3.0\Configuration
Bydefault,  BizTalk will attempt to recover receive locations from fault inevery cache refresh interval. You can change this value (seconds) by adding DWORD ReceiverFaultToleranceRetryIntervalwith any other desired value at following locations:
 
  • For 64 bit BizTalk host instances: HKLM\SOFTWARE\Microsoft\BizTalk Server\3.0\Configuration
  • For 32 bit BizTalk host instances: HKLM\SOFTWARE\Wow6432Node\Microsoft\BizTalk Server\3.0\Configuration
