2 Objectives And Takeaways
4/1/2017 6:56 AM Objectives And Takeaways Objective(s): Some complex BizTalk solutions run into problems NONE should! Raise awareness of key tools and techniques to dramatically improve customers experience Based on real world experience Drive the quality of enterprise-class BizTalk solutions up Administration is also key.. © 2005 Microsoft Corporation.

3 BizTalk, Testing, No Time!
We all know testing is important for every solution Customers rarely test well enough... but get away with it Solutions using BizTalk tend to be extremely business critical and tolerate no downtime Poor testing runs the risk of huge technical and political problems Extensive testing must always be performed, no excuses!

4 Testing approach “Test early, often and comprehensively”
Ensure that a demonstrator is created early on to prove concepts, patterns and indicative performance Too many solutions are found to perform badly in the last few weeks for any number of reasons Highlights sub-optimal design up-front Identifies where the bottlenecks are likely to be Increases confidence

5 We sometimes hear... “it doesn’t scale”
“it doesn’t meet our performance requirements” “we were told it would do XX msgs/sec” BizTalk is not A universal panacea Optimised for every customer scenario out-of-the-box Able to make bad code, good code BizTalk is part of the overall end-to-end solution

6 A great “case study” “ [BizUnit,LoadGen,MSTest] provides the ability to reliably and automatically execute hundreds of test cases that otherwise would have to be performed manually” “improved turn around times by a factor of upwards of 5. For a test pack containing 100 test cases which took up to 3 days to complete manually we can now execute in approx 3 hrs”

7 Laying the foundations
Critical to achieving representative performance within your environment Benchmark your environment File Adapter -> File Adapter (3K) message should get ~500msgs/sec Don’t run perf tests on workstation hardware Beware of virtual machines Invest in SQL Server Hardware and Disks Beware of UNC FILE Adapter locations Message Tracking Remember Virus Scanners

8 Foundation Checklist Databases and Logs separated onto separate drive letters and therefore separate physical hard drives? Are the drives used for Databases and Logs configured on a fast disk-array and with RAID10/0+1? Next generation SAN technology tends to use huge caches so RAID choice is becoming unimportant Default Database Autogrowth settings changes or AutoGrowth disabled? SQL Server Agent Running? Have you created separate Receive, Orchestration and Send Hosts and moved the appropriate Adapters and Orchestrations to the appropriate host? Concurrent Web Service Calls configuration file setting changed? <system.net> <connectionManagement> <add address="*” maxconnection="80"/> </connectionManagement> </system.net>

9 PerfMon Counters..... ?? A huge selection of performance counters are made available by the BizTalk engine It can be time consuming to identify the counters you need especially when you have multiple machines Collection of counters is key

10 Excel spreadsheet to define counter collection for multiple machines

11 Visual Studio Profiler
New with Visual Studio Team Developer Ideal for profiling custom code: custom pipeline components, .NET class libraries Profiler can be installed standalone for servers.. vs_profiler.exe located in the \vs\wcu\profiler directory of the VSTS media Must be driven via the command line to attach to a service

12 Configuring the VS Profiler
VSPerfClrEnv /globalsampleon VSPerfCmd /start:sample /output:“c:\dir\profileroutput" VSPerfCmd /attach:<PID> VSPerfCmd /detach:<PID> VSPerfCmd /shutdown VSPerfClrEnv /globaloff

13

14 Code Coverage Enables you to understand what code has been executed during your test run Identifies holes in your testing Ideal for custom pipeline components, helper assemblies, web services, etc. vsinstr –coverage “YOURASSEMBLY” vsperfmon –coverage –output “filename.coverage” vsperfcmd /shutdown

16 BizUnit Test Cases are constructed from generic and reusable test steps Test cases described using an XML syntax Driven from NUNIT or MSTest Model every “use case” within your solution Run a test If you get a “green light” your solution functions at a requirements level Incredibly powerful, not just for the development lifecycle but for changes, new releases..... Not just about BizTalk

23 Orchestration Profiler

33 Summary Get the environment right before any testing
Start testing early, and often. A “demonstrator” is key for complex scenarios Use BizUnit for modelling “use cases” Use LoadGen for generating load Use Orchestration Profiler to ensure your “touching” all parts of your solution during testing Use BizUnit and LoadGen together to automate your tests
