It is when that which does the polling sends an "Are you still there?" package to that which it is connected to, hoping to hear a "Yes I am here" come back.

If it doesn't get this response then it deems the connection to have been lost.

Therefor "Connection Polling" is the art of keeping an eye on your connections to make sure they are all doing ok.

Hi Gen!
Thanx for your reply. Are u talking about the databse connections? or is that applicable for any kind of connections..(like winsock for instance)

"Connection Polling" is a methodology... this means it can be applied to anything that would feasibly be considered as a "Connection".

If you are talking about doing it yourself then yes you can do "Connection Polling" on winsock connections.

I am sure things like SQL Server have their own methods for making sure database connections are valid which *might* involve Connection Polling but there are more methodologies than just this one.


With programming and computers in general there are "methods" and then there are implementations of those methods. You have to try and not confuse the two as one is kind of like "Pseudo-Code" while the other one is compiled and ready to go.
