oracle dblink

Hi,
How dblinks work internally? If there is one dblink and more request at one time then ,is it shared among the requests and requests are queued or mulitple instances are created one for each request?
It would be great If I could find material which says wbout oracle dblink basics, creation , usage and management.

Thanks & Regards
Alok

If we use dblink for any online querying So do you see any performace problem , as for each request it will have to open a new session .I will tell you where I am comig from is...I have a local DB with few load and a remote DB with lot of tables.Remote DB is providing views to which I can query for my purpose.So I am just comparing options of either opening a JDBC connection directly to remote DB or access that through dblink through jdbc on local DB.

could you please tell me pros and cons of dblink in this regard.

Thanks & Regards

There can be lot of queries, as it's going to be an enquiry system.There can be 50 simultaneous queries at one time.. though all these are just select statements and there can be any number of queries in a day by a user.
What problems do you perceive when there are more number of queries in dblink?
