database pool connectivity

Hi,

I am on j2ee 6.20 . I already have one jdbc connectivity for oracle maintained. One more connection has to be maintained for oracle jdbc. When I navigate to server dbpool through VA ,I dont get any option to create a new pool(ie New)but there is an option to add new driver.Since I want to use the existing driver already maintained . Pls suggest how can I create a new pool.

Thanks

Ravi
