HAT starts very slowly RRS feed

  • Question


    Hi all,


    i have a  problem with the btshatapp starting very slowly. I have several BizTalk Servers in a farm. On machine 1, the HAT starts after a few seconds, on machine 2 (same farm) it takes more than 30 seconds. As soon as it starts it works fine, i don´t get any timeouts when executing queries. Does anybody have an idea as to why this could happen?

    Also, this delay might actually be related to the topology of your SQL Server machines. Could you give more information about how SQL Server is organized in your environment? Also, are all of the BizTalk databases located on a single server? What you experiencing could be caused by the load on your SQL Servers so a recommended practice is to spread BizTalk databases across different filegroups or SQL Server instances for better performance. Here are a few links on database optimization techniques (like the filegroup one) for BizTalk:, and
