More Nonsense

I know I need to let this go, but I can't stop thinking about the nonsense of this BPMN -> JCAPS -> .Net web service architecture proposed by management at the client I'm working with.
  • The main reason for the base web services to be implemented in .Net rather than directly in JCAPS is that this organization has 10x as many .Net developers as it has Java/JCAPS developers. The thinking is that this ratio will make it easier to find available bodies to maintain and enhance these services. While this makes sense, any guess on how many people know BPMN? A small handful... all of them contractors. There's not even a BPMN modeling tool in place at the company. Yet they're convinced this is the way to go.
  • Is it reasonable to expect business users to create BPMN models? While I realize the GUI interface makes it less like "coding", I think that it'd be helpful to have a basic understanding of boolean logic, parallelism, and exception processing in creating the business models. While I've seen some amazing Excel applications created by business users, the assumption that these people will be able to create high availability, high throughput applications is a bit of a reach for me.
  • All the excitement over BPM reminds me of the EJB "revolution" - when the mantra at many companies was "EJB everywhere" and EJBs were the architectural style du jour. EJBs were (poorly) implemented in many places where they weren't a good fit. Many of these applications had scalability and performance problems. I'm wondering if this BPM "revolution" will produce similar results. (Is there a reason it's called Business Model Notation rather than Business Application Notation?)
  • In a system like this, it's important to think about how service enhancements are rolled out. No one is talking about how these services will be maintained, released, or tested. Will there be a period of backward compatibility for service clients? How will that be handled? This lack of foresight is another reason I feel this company is not ready for SOA.

On numerous occasions I've approached the client to discuss these things with little success. I can't get them to recognize that many of their problems result from their (lack of) process rather than problems with their technology. I wish I knew of a better way to get through to them.

I Believe...

A recent reorg at my company left me with a new manager - and a different approach to software development than my team had been previously following.  Our new approach is one that I don’t necessarily agree with, but it led me to think about - and reevaluate -  those tenets of software development that I think are important and that I believe lead to increased quality and productivity. This post will consist of fairly high level discussions about how to organize code, teams, and projects - but contain very little actual code. Many of these ideas will not be my own.  They are mostly ideas I’ve learned from others and their willingness to share their experiences with me.  They are, however, ideas that I’ve practiced and hardened as I’ve worked to build my own ideal environment for delivering value through software . Many of these ideas I now take for granted as commonplace (even though they aren’t).  I felt a need to document them anyway - so people can understand what to expect (a

FRail :include

I really like developing with Rails, but I've been frustrated the last few days by some things Rails should do quite easily, yet doesn't. I've already written here and here about some of my struggles with Rails :include clause. Here's one more... Let's say you have a has-and-belongs-to-many relationship. If you :include this relationship in a find query, Rails will automatically create the join clause including the lookup table! That's cool. Unfortunately, it looks as if only the :include clause provides this piece of functionality. Why isn't the same functionality provided via the :join clause or through a general purpose module? This doesn't make any sense to me! I'm working on a database application where I don't need to display a lot of data, but the data displayed is heavily filtered by it's connections to other information in the database. I need to join a lot of tables to perform the filtering operation and using :include

Performance Tuning JCAPS - Part 2

It's been close to 2 months since my first Performance Tuning JCAPS post. Since then, we've noticed our servers running out of TCP connections under heavy load. Researching this problem, we learned that the JCAPS' JMS server makes heavy use of TCP in implementing Request/Reply queues . We approached Sun for guidance and they assured us that they've had success implementing high throughput applications using the JMS request reply solution... but how? It appears a multi-step solution is needed. First, running out of TCP connections in a scenario like ours is a JCAPS bug addressed in an ESR (110348) and rolled into JCAPS 5.1.3 Update Release 3 . We installed this update and noticed a marked improvement. Running my simple 75 user simulated test, transactions took 2521 ms to round trip (compared to the previous time of 20128ms). While this is great improvement, an average of 2.5 seconds is still really slow for this simple transaction. We reported our findings to Su
