Red Hat JBoss Fuse - Healthcare integration demo Part One

Continue on with the topic from last week, I want to try to demonstrate how JBoss Fuse can help to build a more robust, and agile healthcare integration solution. In this blog I will explain what the demo is about, how to install and play with the demo. You can access the code base here:  I tried to mimic a common situation when we visit a clinic or hospital. Lets start by looking at the departments. There are 5 different parties involve. As you can see, these are commonly found in healthcare and they uses different data format and talks in various protocol. just like what it would be in real life. 
  • Front Registration Desk
    • Responsible for patient registration 
    • Sending registered patient to all departments
    • Storing patient registration data
    • Talks in HL7 v2
  • Doctor Clinic 
    • Receives registration info
    • For clinical prescriptions 
    • Doctor sending patients to eithe lab test or radiology x-ray
    • Recording paitent condition
    • HL7
    • Messaging broker
  • Laboratories
    • Receives registration info
    • Schedule Lab test for patients
    • FHIR
    • Restful Endpoint
  • Radiology 
    • Receives registration info
    • Schedule x-ray test for patients
    • HL7
    • MLLP socket
  • Pharmacies  
    • Ask for patient prescriptions data
    • JSON
    • Restful Endpoint
  • Insurance company
    • Get all patient registration data
We first by registering ourselves in the front desk, the front desk will get the registration information, and system will store these data for insurance company that will later be collect via their batch system. Then the register data are sent to all the departments in the hospitals. After that the patient is then sent to doctor clinic for quick diagnose, this is when the doctor will decide to either send them on to more detailed test, radiology scan or simply give prescription. For the lab in the hospital, it will receive both the registration administration data and the request for different test coming from clinic. Same applies to Radiology system. Lastly when the patients tries to get their prescription from the pharmacy, it's application will link back to the hospital to check the validity and content of the prescribed medicines. 

To make this demo more real, these department application does not speak the same language, below is the diagram that shows what context of data format each department expect. 

Both the clinic and Radiology department uses the most common HL7 v2 format, HL7 is the most common standards for transfer of clinical and administrative data between software applications by healthcare providers. The messages use a non-XML encoding syntax based on segments (lines) and one-character delimiters. It's a very complex data because not only it tries to cover many aspect in healthcare industry, but since the evolution of technology, many customization was implemented over the years, making it hard to decode and read. Even using this format, many vendors interoperate it differently. And we also have FHIR, which is the new data format pushing by the same community by trying to address the problem HL& v2 and 3 has. It supports better with the mobile and uses the concepts of hierarchical resources. And we also have pharmacy which is an outside vendor that requires a specific data format.   

To install the demo, please make sure you have installed Vagrant and Virtual Box beforehand. Go to my repository and clone the project by running 

 git clone MY_REPO_URL 

Go to the project directory and run 

Start build and deploy JBoss Fuse Camel services by goingu nder project directory ./projects/healthcaredemo and run

     mvn -Pf8-local-deploy

After projects are depolyed, go back to the demo root directory (where the is) we want to create two extra services 

     oc create -f support/clinichl7service.json
  oc create -f support/labrestservice.json

Also expose a new route for the Lab Rest API Service 

     oc create -f support/labrestapi.json 

You can take a look at the pods and service that are running inside OpenShift, by login to OpenShift console with USERNAME/PWD admin/admin

And start playing with the demo by registering your info, by going into the page you will see different sections, 

You can start by registering your patient information then schedule different test by entering different fields. 
Next week, I will be talking about my approach to break this problem done into microservices.

Red Hat Fuse - Announcing Fuse 7 Tech preview 3 release.

Red Hat Fuse 7.0 technical preview three is out today! On the pathway to become one of the best cloud-native integration platform, Fuse gives developer freedom to choose how they want to develop the integration solution, where they want to deploy it and capabilities to address new integration personas that do not have development experience.
By supporting the three major runtime, developer is free to work on the runtime of their choice.By supporting standalone and cloud deployment, it simplifies the complexity to distinguish between these environments, allowing application to deploy freely among the environment of your choice. All levels of developers are welcome, you can either dive deep into creating customize complex integration logic, or using the new low code platform to quickly build a simple integration. In this Tech Preview release you get it all.

JBoss EAP 6 - 效能調校 (一) DataSource 的 Connection Pool

效能沒有什麼Best Practice, 反正能調整的就那些。 通常,一個程式的效能大概有70-80% 都跟程式怎麼寫的其實比較有關係。

最近我最疼愛的小貓Puji 因為膀胱結石開刀的時候過世了,心情很差請原諒我的口氣沒有很好,也沒有心情寫部落格。

JBoss 的 SubsystemDatasource WebWeb Service EJB Hibernate JMSJCAJVM 調校OS (作業系統)

先來看一下 DataSource Subsystem, DataSource 的部分主要是針對Connection Pool 做調校。

通常,程式都會需要跟資料庫界接,電腦在本機,尤其是在記憶體的運算很快,但是一旦要外部的資源連接,就是會非常的耗資源。所以現在的應用程式伺服器都會有個Pool 放一些先連接好的 資料庫connection,當程式有需要的時候就可以馬上提供,而不用花那些多餘的資源去連接資料庫。

這就是為什麼要針對Connection Pool 去做調校。

以下會討論到的參數,都是跟效能比較有關係,Datasource 還有很多參數,像是檢核connection 是否正確的,我都不會提到。如果你追求的是非常快速的效能,那我建議你一個檢核都不要加。當然,這樣就會為伺服器上面執行的程式帶來風險。這就是你要在效能與正確,安全性上面的取捨了。 (套句我朋友說的話,不可能又要馬兒好,又要馬兒不吃草的..)

最重要的調校參數就是 Connection 的 Pool 數量。(也就是那個Pool 裡面要放幾條的connection.) 這個參數是每一個應用程式都不一樣的。


Connection Pool 最少會存留的connection 數量


Connection Pool 最多可以開啓的 connection 數量


事先將connection pool 裡面建立好min-pool-size 的connection.

我的建議是觀察一下平常程式要用到的量設定為 min-pool-size 。

My 2cents on the future of Integration - With Service Mesh/Istio and Serverless/KNative

It's been a year and half since I blogged about "Agile Integration architecture" (Gosh, time just flies). With the "microservices" and "cloud-native" hype, I was especially curious on how all these new concept and technology affect us on how to architect the integration systems. If you ever pay close attention to all the latest and greatest news from the Kubernetes community, I am sure you will hear a lot about the new "Service Mesh". And rumor has it that this is how integration can/should be done in cloud native world, but, is that so? Anyone who has ever worked on an integration project would tell you, it's a LOT more COMPLEX and can get worst overtime. I did a talk with Christian Posta in Red Hat Tech Exchange coming from a more comprehensive view of how different Red Hat technologies are applied under different patterns when building integration solutions. In fact he also did a great blog about it.

Since then, another topics has be…
