DTL TechFAQ

#Ensemble #DTL

Ensemble is based on message flow, and a data transformation is a way to convert from one message type to another. DTL (Data Transformation Language) adds a layer to this - it provides a graphical way to do the conversion. This is really helpful because most of the time, people with domain-specific knowledge may not have extensive coding skills. However, you always have the ability to do some coding, so if you need or want to, this is available.

DTL has several components: the data transformation engine, the language itself, and the DTL editor.

Behavior of Ensemble following a system failure and restart

#Ensemble

Introduction

This paper describes how Ensemble behaves after a system crash or similar uncontrolled shutdown or failover. Ensemble is normally configured to start processing messages automatically when the operating system restarts or when the system has failed over to a cluster member or mirror member. No manual intervention is required. But, in order for your system to robustly handle system failure and restart, you must understand how Ensemble handles these conditions and develop your productions using the rules and guidelines in this document.

The behavior in the event of a restart is very dependent on the solution and the participating applications. Ultimately, it is the responsibility of the solution designer to address each possible failure mode.

Controlling Alerts in Your Ensemble or HealthShare HL7 Environment

#Ensemble

Introduction

HL7 V2 message routing solutions often have hundreds of business services, processes and operations. Inevitably things will go wrong and you have to monitor the production to be able to react quickly and resolve any problems before they can become serious issues.

Ensemble includes some powerful alerting capabilities that can help, but if you aren't careful you will be inundated with alerts and your inbox more or less becomes a copy of the event log defeating the object of the exercise.

These notes are based on experience of other customers who have set up alerting and will hopefully be a good starting point for anyone setting up alerting for the first time.

Ensemble in a Service Oriented Architecture

#Ensemble

How do you balance the need to achieve an early success with SOA against the requirement for an architecture that will deliver long term success? You don't want to get bogged down in architectural committees for three years, but you don't want to make short term decisions that will be roadblocks to long term success.

If your first project is to deploy a small number of reusable services in a matter of months but you know that four years from now you might have hundreds of services, an enterprise SOA infrastructure and specialized governance technology you have a dilemma. How do you move forward quickly without defeating your ultimate strategy?

One practical solution is to use a single enterprise integration platform that incorporates all of the functionality of an ESB and SOA backplane and can scale to the largest solutions. By using a single development and management technology Ensemble you can move forward quickly so that your first projects are successful in record time and ensure that in the long term, you have a scalable robust solution.
