Survivor Ratio - Heap Tuning Settings

Survivor Ratio - Heap Tuning Settings
Heap tuning is  very important and interesting concept. There are several levels and many parameters part of this exercise.Now we are going to discuss about survivor ratio.

Survivor Ratio specifies how large Eden should be sized relative to one of the two survivor spaces.if the survivor ratio is 6 then Eden space 6 times greater than the survivor space which is 1:6.
Allocating enough amount of memory in survivor spaces is very important for good performance.If survivor spaces are too small,when GC happens it may overflows directly into the old generation.If survivor spaces is too large we wasting lot memory.



Setting up the SurvivorRatio can be done through the JVM argument -XX:SurvivorRatio=6. For Example we have 2048 MB of young generation memory as per the above survivor ratio it will divided as follows

Total Memory=2048
Total Segments=8(2 survivors + 6 times of Eden as per survivor ratio)
Memory per segment=256 (2048/8)
Survivour 1= 256 MB
Survivour 2= 256 MB
Eden= 1536 MB

Dynamic values in property File

Dynamic values in property File
In java based application most of the times we externalize the constant messages through property files.This property file working in the concept of key value pairs.
There could be a scenario to pass dynamic values in property values. Lets see how can we do that?

First we need to add the place holders in property file. Content of myfile property file looks like below

loginMessage=Welcome {0} your now in {1}


We added two place holders in message above and we can add many place holders based on the requirement. Later this place holders will be replaced with dynamic values. Now i wanted to replace {0} with Raj and {1} with india.

import java.io.File;
import java.io.FileInputStream;
import java.text.MessageFormat;
import java.util.Properties;

public class Test {

  /**
   * @param args
   */
  public static void main(String[] args) {
      try{
      Properties props = new Properties();
      FileInputStream stream=new FileInputStream(new File("F://myfile.properties"));
      props.load(stream);
      String message = props.getProperty("loginMessage");
      String welcome = MessageFormat.format(message, "Raj","India");
      System.out.println(welcome);
      }catch(Exception e){
   
      }
  }

}


Final output:
Welcome Raj your now in India
