HOw to Connect two different database ?

[k r i $ h n a n]

Hello All, 
            I wanted to create a database portlet fetching records from mysql , i made 
necessary changes in tourque.properties and ,connected it with mysql and was able to 
fetch records , but i also need another database portlet which connects with oracle 
database , is there any way to make two different database connections available for 
database portlets , and how to refer those connection. 

thanks in advance.
