My first glance to Oracle Service Bus and compare with it Oracle SOA suite ESB

Recently Oracle gave access to download their new product Oracle ESB (formally known Aqua Logic ESB). Last year one of my project was related with SOA suite ESB. However, there were a few bugs with it, but we completed our project successfully with satisfaction.
When the times came to use Oracle OSB, i wondered with his functionality, a lot of Nodes and Actions pleased me well. At first it seems to be on workspace of BPEL but it's only for using on ESB. All these nodes made easy of ESB development. See the design template at a glance

However i have also found a cons in OSB is that, it haven't contains any built in JCA compatible adapter to connect with another resource. Throw proxy service OSB can use any type of protocol include FTP, SMTP, TUX. OSB defines these type of services SOAP without WSDL and XML without WSDL service. Take a look at the built in adapters in SOA suite ESB.

However, OSB hasn't contain any adapter, through proxy service OSB can integrate with any kind of legacy system and resources.
It would be better to take a glance in the following overall architecture of the OSB:

Link for download OSB.
A good book to learn OSB out here The Definitive Guide to SOA: Oracle® Service Bus, Second Edition.

8 things every developer should know about the Apache Ignite caching

Any technology, no matter how advanced it is, will not be able to solve your problems if you implement it improperly. Caching, precisely when it comes to the use of a distributed caching, can only accelerate your application with the proper use and configurations of it. From this point of view, Apache Ignite is no different, and there are a few steps to consider before using it in the production environment. In this article, we describe various technics that can help you to plan and adequately use of Apache Ignite as cutting-edge caching technology. Do proper capacity planning before using Ignite cluster. Do paperwork for understanding the size of the cache, number of CPUs or how many JVMs will be required. Let’s assume that you are using Hibernate as an ORM in 10 application servers and wish to use Ignite as an L2 cache. Calculate the total memory usages and the number of Ignite nodes you have to need for maintaining your SLA. An incorrect number of the Ignite nodes can become a b...

Analyse with ANT - a sonar way

After the Javaone conference in Moscow, i have found some free hours to play with Sonar . Here is a quick steps to start analyzing with ANT projects. Sonar provides Analyze with ANT document to play around with ANT, i have just modify some parts. Here is it. 1) Download the Sonar Ant Task and put it in your ${ANT_HOME}/lib directory 2) Modify your ANT build.xml as follows: <?xml version = '1.0' encoding = 'windows-1251'?> <project name="abc" default="build" basedir="."> <!-- Define the Sonar task if this hasn't been done in a common script --> <taskdef uri="antlib:org.sonar.ant" resource="org/sonar/ant/antlib.xml"> <classpath path="E:\java\ant\1.8\apache-ant-1.8.0\lib" /> </taskdef> <!-- Out-of-the-box those parameters are optional --> <property name="sonar.jdbc.url" value="jdbc:oracle:thin:@xyz/sirius.xyz" /> <property na...

Writing weblogic logs to database table

By default, oracle weblogic server logging service uses an implementation, based on the Java Logging APIs by using the LogMBean.isLog4jLoggingEnabled attribute. With a few effort you can use log4j with weblogic logging service. In the Administration Console, you can specify Log4j or keep the default Java Logging implementation. In this blog i will describe how to configure log4j with weblogic logging service and writes all the logs messages to database table. Most of all cases it's sufficient to writes log on files, however it's better to get all the logs on table to query on it. In our case we have 3 different web logic servers in our project and our consumer need to get all the logs in one central place to diagnose if something goes wrong. First of all we will create a simple table on our oracle database schema and next configure all other parts. Here we go: 1) CREATE TABLE LOGS (USER_ID VARCHAR2(20), DOMAIN varchar2(50), DATED DATE NOT NULL, LOGGER VARCHAR2(500) NOT...
