BPEL: Beware the use of nested loops in a short running process

dan — Thu, 03 Jul 2008 15:43:25 +0000

One of the restrictions when dealing with a short running process is that it must always run within a single transaction. The implication is that the process must complete within the default transaction timeout window. On an application server, this is 120s. We had an issue where our Process Server was creating a large number of [...]

ESB-CON VI: Lessons Learned on SOA Adoption

In the opening panel, the John Fitzgerald Director of Product Marketing from Software AG mentioned a client’s SOA Lessons Learned. The three points are: Strong Business Sponsorship Start Slow with a Low-Risk Project Integration Competency Center I agree with all three of these points and I’ll provide my thoughts below. Strong Business Sponsorship You aren’t going to be able to get [...]

WSDL Anti-Pattern: xsd:Any and xsd:AnyType To Encapsulate Future Changes

dan — Thu, 24 Apr 2008 16:54:44 +0000

The cousin to yesterday’s WSDL Anti-Pattern: The ‘Single XML String’ Service is the use of the XSD specification’s ‘any’. ‘Any’ literally means “any well-formed XML contained in this section is valid”. ‘anyType’ means “any valid XSD Type”. We can start to see the correlation between the Single XML String service and the use of these [...]

WSDL Anti-Pattern: The ‘Single XML String’ Service

dan — Wed, 23 Apr 2008 14:31:16 +0000

WSDL is a very useful technology. It allows service providers and consumers to agree on namespaces, operation names, the data to be transmitted in a request and the data to expect in a response. All very good things to know, all in a platform neutral way. Now, WSDL tells us what all the elements and attributes [...]

Tip: Agree To Concrete WSDL Definitions before Development Begins

dan — Wed, 16 Apr 2008 17:17:24 +0000

If you are a provider or a consumer about to enter development on a web service, you should have an understanding with your counterpart of the WSDL that defines the service. It should be very well ‘baked’ and changes once development begins should be minimial. Major things like name spaces and object names should rarely change [...]

Impact 2008: SOA Jam – “Foster an External Community for Practitioners”

dan — Fri, 11 Apr 2008 18:01:10 +0000

I’m going to use this post to record the discussion that generated during the Impact 2008 SOA Jam for my idea about “How IBM can foster an external community”. Now that Impact is over, I’d like to keep a copy of it’s point in time, and also allow any future readers to add comments. Foster an [...]

Impact 2008: SOA Jam – “ESB: Too Many Products, Skill Spread too thin”

I’m going to use this post to record the discussion that generated during the Impact 2008 SOA Jam for my idea about “Too ManyESBs, Skill Spread too thin”. Now that Impact is over, I’d like to keep a copy of it’s point in time, and also allow any future readers to add comments. ESB: Too many [...]

Impact 2008: Impressions of Day 2

Day two is in the bag, the B52’s are B-50-done. Perficient and MTS Allstream gave a session about SOA Patterns that I thought was today but was actually yesterday. Oops. Here’s the abstract if you have a time machine: TSP-2518 – Effectively selecting integration patterns Brent Legris, Perficient, Inc., Senior Technical Architect, Olivera Zatezalo, MTS Allstream Inc., [...]

The VETO SOA Pattern

dan — Tue, 01 Apr 2008 15:52:38 +0000

I’ve never been much of a patterns guy. I kind of always have the ability to apply common sense to a system and turn up something that is straight forward and makes sense. Periodically I get asked about what set of patterns I used to decide how a system should behave. To answer this question [...]

Response to ‘Does Commercial Enterprise Software Suck’

dan — Tue, 01 Apr 2008 15:13:12 +0000

Just wanted to point out to my readers that Johannes Brodwall has provided a ‘response to my response‘ on the topic of his post about the state of WebSphere. This blog doesn’t get too many comments, so I felt the need to point it out as he provides his opinions on WebSphere vs an OSS [...]

Oracle SOA Suite 11g – Hello Competition!

dan — Wed, 26 Mar 2008 15:10:55 +0000

As I’m sure you can tell, I’m very WebSphere focused. I have a hard enough time keeping up with the zillion WebSphere branded products that get released throughout the year. On my random surfing of the internet (tyvm Technorati) , I turned up Oracle’s entry into the world of SOA: Oracle SOA Suite 11g. The interesting [...]

Does Commerical Enterprise Software Suck?

dan — Tue, 25 Mar 2008 15:39:21 +0000

In Johannes Brodwall’s Blog, he asks “Why does so much enterprise commercial software suck?”. In it, he mentions that his project migrated off of WebSphere and onto Jetty and regrets that his project didn’t migrate soon. The money quote: But WebSphere is just the most blatant example of software that gives you nothing, gets in the [...]

WebSphere DataPower vs WebSphere Enterprise Service Bus

dan — Tue, 18 Mar 2008 19:03:35 +0000

Yesterday, I blathered on about how great DataPower would be for usage in WebSphere Process Server. Your developer would be able to stay completely inside the Generic Business Object (GBO) data view while leveraging DataPower’s awesome ability to transform efficiently. Very neat indeed. An interesting is scenario where DataPower IS the ESB. No WebSphere Process Server, [...]

Business Integration Software Bakeoff Idea

dan — Fri, 14 Mar 2008 15:58:57 +0000

In my random browsing of the internet, I came across Wikipedia’s comparison of Business Integration Software. I’m so WebSphere focused that I didn’t even know there were this many companies out there with “ESB” products (34). It sparked an idea in my head, I wonder what it would be like to bake-off all these solutions [...]

JDBC Adapter Export with events that comprise multiple rows

dan — Fri, 29 Feb 2008 03:08:33 +0000

At my client, we had a unique situation occur when integrating a database and an export for the WebSphere Adapter for JDBC. In a ‘typical’ scenario, a single row is written into a staging table, an SQL trigger writes this single row into the adapter’s event table, the adapter polls, converts the data into a [...]
