for example if 2000 users use my application simultaneously how many connections i can define for my application.
and also if 10000 users use at a time how many connections we need to go for.

this is a general question in my mind ...

Connection Pooling,

1. when to use connection pooling.
2. On which factor the no. of connections parameter depend.

example :
To access my application by 2000 users we can define 20 connections.
if the users increases to 10000 then how many connections we require to access my application.

please clarify me on this.
PreparedStatement are pre compiled statements could you please let me know what it is.

The JRE wouldn't know anything about your marker interface, so any special treatment would have to happen in the code you write. Probably in sections such as "if (someObject instanceof ExampleMarker) { ... }".

You shouldn't create marker interfaces, though. That's what annotations are used for these days.



Hi Thanks for your reply.
i am really worried about this marker interface ... as i have not written my own maker interface ... in my exp. as of now.
I do really face this question while attending interviews... they told that we can write our own marker interface and inform JVM about it.....
still finding for a solution on this.

How to write our own Marker Interface..? how to write a Marker Interface similar to serilizable Interface.

We can write our Marker as interface ExampleMarker { } similar to Serializable interface.
But how to define the functionality as there some meaning in implementing Serializable interface.

Please suggest me.
