concurency testing in thick client using more than 100 threads

Hi,

Thanks for giving response.

My domain is Stock Market and using thick client.

I am saving one record in to the database in my application by clicking on Register button. If I were click on Register button in 100 machines at a time, then the record should save through only one system in the remaining machines i need to get exception.

But I can't check it using 100 machines, So do we have any approach to check this scenario in my system i.e. only in one system.

Thanks.

Hm interesting problem ,

one way i think of doing this is

1) decide at what time you want to fire the actions . for example you want to fire after 9000 millisecond (9 seconds)

2) write the main as

class mainclass {

static long timetofire=0;

main() {

timetofire = system.currentmillisec..() + 9000 ;

//spawn 100 threads

}

}

run of the thread will be like this

run () {

sleep ( timetofire - system.currentmillisec())

//firetheAction

}

Even though the thread scheduling will delay few milli seconds . but if you try this with multiple process i think you will get the same result as you ar expecting .
