Oracle Coherence Cache Mangement

Oracle has got Coherence Cache management product by acquiring Tangasole. Coherence provides data management and cacheing service. It is not just simple caching service. It provides much more than it, such as 
  • Distributed
  • replicated 
  • reliable
  • scalable 
  • clustered 
  • automatic load balanced 
  • consistent 
  • indexed
 in-memory  data management.  

Using Coherence, you can have distributed cache management over clustered network. IT provides several implementations , such as 
  • Local Cache 
  • Replicated Cache
  • Partitioned
  • Near Cache 
The most interesting feature is ease of installation and implementation. Installation of coherence is only one step process, just include jars in path.  
Following are few step to install, implement and test it [ Only basic implementation ]
1. Installation
Download and unzip step up  archive from Oracle Coherence home page

2.  Update Classpath
Include coherence.jar in  your CLASS_PATH, you will find this jar at coherence_home/lib/

3. Implementing using java 
//Create named cache using CacheFactory 
NamedCache cache = CacheFactory.getCache("cache_name");

//using cache, putting data in cache
cache.put("key","value");

//accessing data 
Object value = cahce.get("key");


That's it, only simple 2-3 steps and you are done with installing, putting and accessing get

Composite Design Pattern by example

Image
This post explains Composite design pattern with an example. When to use ? – Use Composite pattern when you have treat a collection of objects as they were once one thing. With Composite design pattern it is very easy to simplify operations over collection data structure. It reduces complexity of the code required if you were going to handle collection as special case. How to Use? - The Composite pattern consist of Component, Leaf and Composite Classes as shown below class diagram Component – Component declares the common interface that both the single and composite nodes will implements Leaf – The leaf class represent the singular atomic data type implementing he component interface.     Composite – Composite is an abstract entity which declares common functionality which are needed by concrete implementation for handling collection data. An Example -   Item.java public interface Item {     public double getPrice(); }   ColdDrink.java pu

State Design Pattern by Example

Image
State pattern falls under the category of Behavioral patterns. State design pattern comes in picture when a system’s behavior is depends on its own state or some other resource’s state. If an implementation is depends on the states, we end up with snarl of conditional statement every where in code. A very neat approach to deal with such situation is to separate out every state’s behavior and use them where ever they are applicable. The state pattern allows an object to alter its behavior when is internal state changes . The object is appeared to change its class. State pattern is a way to implement the same. Class Diagram : As above class diagram shows, System class holds state instance. As state of system changes , all handle request delegated to respective State’s concrete implementation. Example : Have an example of Vending machine. Vending machine has following states No Coin Inserted Coin Inserted Dispensing Empty Following diagram explain behavior

Eclipse command framework core expression: Property tester

Image
Addition to Eclipse command framework series, this post explains use of property tester to control command’s enable/visible properties. In earlier post we have tried declarative way to achieve same thing but property tester gives us more control. Property tester is associated with, tester class which implements PropertyTester.java, a namespace and set of property which it supports. We can refer this property tester using its namespace + a property name. It gives you call back to test() method with property name as parameter inside property tester class. We can configure property tester for type of input parameter. Here is sample declaration of property tester extension point < extension point ="org.eclipse.core.expressions.propertyTesters" > < propertyTester class ="com.example.advance.cmd.EditorTester" id ="com.example.advance.cmd.propertyTester1" namespace ="com.example.advance.cm
