What is Isolated Storage and Why use It?
Putting it simply, an isolated storage is a “place” where an application can store its state information- things such as user settings, some assembly and application configuration information, and other application/assembly state information. So what is so different about that right?
Well a few things and some of these pertain to or relate to application and computer security. Let me explain, usually when an application tries to persist application state, it has to deal with user access rights, trust levels and so on. One way to resolve this is to give the application whatever rights it needs and potentially open up your computer to malware and spyware. Another way is to save information in the database. Now, the latter might be a viable option but in some cases complicates matters. Remeber when you just…
The BizTalk 2006 R2 Management Pack is a rewrite from the original pack for Microsoft Operations Manager 2005 (MOM). It is designed around all of the new features of BizTalk 2006 R2 including RFID and EDI. The pack ties into SCOM very nicely and once it has been imported into SCOM, it can automatically scan the network and will detect your BizTalk environment.
The main purpose of the pack is to
· Monitor BizTalk events
· Collect BizTalk specific performance counters in one central location
· Raise alerts on events
This pack is designed to provide the following services
· Availability Monitoring
This can detected a multitude of items with very little configuration. It will automatically detect if a send or receive port goes down, connection problems with the BizTalk database, messaging engine connection issues with the SSO database.
· Health Monitoring
You can use Health Monitoring rules to…
For those in the Connecticut area…
Tallan is providing a complimentary executive lunch around the topic of Microsoft Integration. It includes a talk by Tom Stickle, Program Manager at Microsoft for the Connected Systems Division, about the new integration features in BizTalk. In addition, there will be a real-life integration case study from a CT-based company.
The event will be held from 11:00 AM until 1:00 PM on June 10th at Lake of Isles in North Stonington, CT (part of the Foxwoods Resort), where an executive lunch will be served.
Here is the link to more information about this event and how to register.
I gave a presentation on BizTalk High Availability options to the New England chapter of the BizTalk user Group on May 14th.
Here is a link if you are interested in downloading the presentation (powerpoint 97-2003 format).
During my time with Tallan I have worked in both the MS camp and the Java camp. I prefer the Java side but I acknowledge that neither side is perfect. One of the main issues I see on the Java side is the huge variety choices that an architect has when starting a new project. I saw this article on DZone that seemed to summarize the situation well:
There is an interesting link from this blog posting. I have not read it in depth. It looked good on an initial skim. The author seems to be trying to be objective, rather than selling one framework over another. (Go past the pictures of his family… would be interesting to hear the presentation that goes along with this PDF):
Comparison of frameworks:
I am interested in hearing others point of view on this (not looking…
If you want all resources of your BizTalk application to be registered in GAC on MSI import, it is necessary, prior to exporting BizTalk application to MSI file, to check ‘Add to the global assembly cache on MSI imports (gacutil)’ option in Modify Resources dialog box. This option is unchecked by default. To avoid the need of doing it for each resource separately, do the following:
Open dbo.bts_application table in BizTalkMgmtDb database
Find application name in nvcName column and write down the Application ID (nID column)
Run this update statement in BizTalkMgmtDb database (replace <app_id> with Application ID retrieved in #2):
update dbo.adpl_sat set properties = replace(cast(properties as nvarchar(4000)),
‘UpdateGacOnImport</key><value>False’, ‘UpdateGacOnImport</key><value>True’) where applicationId = <app_id>
Found a great resource today for how to go about testing BizTalk applications. It covers best practices on how to unit test various BizTalk artifacts such as schemas, maps, pipelines, orchestrations. This covers how these should be covered with tests for integration testing as well as functional testing. Very interesting read.
One of the tasks developers find most tedious is documentation. It gets to the point that documentation never gets done in many cases. This is where documentation tools comes in handy. There is a documentation tool that is available that analyzes the BizTalk application and creates a CHM file containing:
Send & Receive Ports
Schemas & Maps
The tool is an open source project that can be found on CodePlex:
Murphy’s Law: if anything can go wrong, it will. If BizTalk orchestration instance in a production server does not behavior as you expect it, how do you diagnose the problem? Remember, attaching debugger to an orchestration instance is usually impossible in this case.
DebugView is one of my favorite tools for troubleshooting issues in production environment. For many years, I have used it to debug Visual C++, Visual Basic, C#, ASP and ASP.Net web applications. No exceptions, I use it for BizTalk orchestration debug too. The System.Diagnostics.Trace.WriteLine method can be used to output string. Under the hood, it will call Win 32 OutputDebugString method. If DebugView is not enabled, there is no performance penalty. However, this method will hurt performance if you launch DebugView. In case you don’t have this tool, you can download free one here.
Alternatively, the System.Diagnostics.EventLog.WriteEntry method is…
I was recently looking for a unit test coverage analyzer such as JCoverage for a project I’m working on. After reviewing several tools I discovered an amazing free tool called EclEmma.
I’ve used JCoverage in the past and while it’s HTML based reports are useful for project managers they are less so for developers. This tool essentially gives you the same information, but directly in Eclipse. You simply run the analyzer on either a single class or a set of classes and viola… you have your coverage report.
It even color codes each line of code within your editor window.
Use the http://update.eclemma.org/ update site to install EclEmma.
