Hi,
I am using the for caching. I am able to put and get the items upto 3 lac. If I try the application with more than 3 lac, I am not able to get some of items back. It returns null.
I am posting the code :
package ehcache;

}
System.err.println("Memory : "+ cache.getMaxElementsInMemory() + " Disk : "+ cache.getMemoryStoreSize());
long nEnd = (Long) new Date().getTime();
System.out.println("Total consumed EHCache Time : " + (nEnd - nStart));

// manager.shutdown();

System.out.println("Exception :" +ex.toString()+" message :" + ex.getMessage());
nEnd = (Long) new Date().getTime();
System.out.println("Total Get consumed EHCache Time : " + (nEnd - nStart));

}
public static void main(String[] arg){
EHCacheTest objEHCacheTest = new EHCacheTest();
long nmax=2000;
objEHCacheTest.writeToEHCache(nmax);
objEHCacheTest.readFromEHCache(nmax);
}
}
I am using the default configuration.
