JBoss Fuse - JBoss BPM Microservices Integration

Early this year we announced the exciting example project for JBoss BPM Suite that centers around a working online Travel Agency project. This initially leveraged web services, that we later migrated to microservices with the help of JBoss Fuse. And now the more exiting part, upgrading to JBoss Fuse 6.2, we wanted to revisit the project and make sure you had the latest greatest products at your disposal.

With a bit of work, some spit and polish, we think you will enjoy the all new JBoss BPM Suite & JBoss Fuse Travel Agency Integration Demo up to date and feel that you have a great example of their microservices integration capabilities.
Travel booking process.

This project provides an automated installation (repeatable) in minutes where you get JBoss BPM Suite running on an instance of JBoss EAP and a separate instance of JBoss Fuse with an automated install of 6 microservices each distributed container!

This demo is brought to you in part by Eric Schabell, who is the JBoss Technology Evangelist focusing on JBoss BPM Suite. If you have a use case you would like to see then just let us know by raising an issue on the project.

Watch the microservice do it's work!
The project can be found on github and has documentation to get you up and running in minutes.

Demo details

Upon starting the server you will find a JBoss BPM Suite setup with the Travel Agency project ready for you to inspect, build and deploy for use by the JBoss Fuse microservices you will be deploying in their own containers.

The JBoss Fuse component of this demo consists of pre-configured microservice containers which we will then have you start once JBoss Fuse has started. Once they are up and running each instance of booking a flight will leverage the microservices which you can view in the JBoss Fuse console.

In this version of traveling agency, we have updated a few things in our camel route,

  • Replace OpenJPA with Hibernate
  • Using RestDSL new in JBoss Fuse


Installing and running

The following steps will get you up and running in a matter of minutes with this fully automated and repeatable demo:
  1. 6 microservices in 6 containers!
  2. Add products to installs directory.
  3. Run 'init.sh' or 'init.bat' file. 'init.bat' must be run with Administrative privileges.
  4. Start the JBoss BPM Suite server, login, build and deploy JBoss BPM Suite process project at http://localhost:8080/business-central (u:erics/p:bpmsuite1!).
  5. Add fabric server passwords for Maven Plugin to your ~/.m2/settings.xml file the fabric server's user and password so that the maven plugin can login to the fabric.
     <!-- Server login to upload to fabric. -->
     <servers>
         <server>
             <id>fabric8.upload.repo</id>
             <username>admin</username>
             <password>admin</password>
         </server>
     </servers> 
    
  6. Start Fuse Server, by running 'fuse' or 'fuse.bat':
  7. Login to Fuse management console at: http://localhost:8181 (u:admin/p:admin).
  8. Looking to Automate your business?
    Under Services -> Containers tab, you will see 6 containers, select and start each one. 
  9. Check if web services are available under Services -> APIs tab. 
  10. Enjoy the demo!
We hope you enjoy this updated demo showcasing JBoss Fuse integration with JBoss BPM Suite.

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。

Puji R.I.P.

=======================正文=======================

這個題目很多人叫我寫,可是這題目好大,這分明就是整死我咩~
所以我會分幾段慢慢寫。

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。

min-pool-size 

Connection Pool 最少會存留的connection 數量

max-pool-size 

Connection Pool 最多可以開啓的 connection 數量

prefill

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 。

Red Hat JBoss Fuse/A-MQ - Fuse and A-MQ Version 6.3 GA is released!

Fuse and A-MQ 6.3 GA has just went out. Maybe, you would think this is just only a minor version release why should I care? Hold your thoughts on that! Because they have done a lot of improvements and also added many new features into this release.

Besides various bug fixes and making sure Fuse Fabric is much more stable. There are two major change in this version update:

New Tooling in JBoss Developer Studio (JBDS) 9.1 GA. Newer Apache Camel version – Camel v2.17. I was really impressed by the work put in to make developing Camel application much simpler. First is the installation of tooling itself. Now it has a all-in-one installer so you don't need to worry about which plugins you need to check. See the videos below to see the new "Getting Started" of Fuse 6.3.



And If you notice from the above video, the presentation of camel route in JBDS has also updated. It fixed some of the miss representation of logic and making it easier to read.

Old Camel Route

Red Hat JBoss Fuse - Getting Started with Fuse Integration Service 2.0 Tech preview

I just realized that I did not do a getting started for Fuse Integration Service 2.0 Tech preview before I did the pipeline demo, thanks for those of you who reminded me! :)

To get started with FIS 2.0, for people who has just getting to know the technology, here is how I interpret it. Basically, it's divide into two aspect,

1. Integration development, FIS uses Apache Camel as the core technology that creates, orchestrate, compose microservices into a super lightweight thin integration layer, and become the API provider and service orchestrator through exposing RESTful or messaging service endpoints. And you can choose to either package and run it with Spring-Boot or Karaf.


2. Application Deployment and Management, FIS takes advantages of OpenShift platform, and allows you to separately deploy the micro-integration service among distributed environment, at the same time takes care of the failover, high availability, load balancing and service lookup problem for you.


So, now we know …
