Subject RE: Database Connection without Datasource
Date Thu, 03 Mar 2005 07:44:43 GMT
Hi Bharat,

You wont have to as the SIMPLE type does not use dbcp from apache
but any pooling properites offered by the jdbc driver itself.
You do not have to set any of these values they are optional. I have
a similar requirment and i have no dependancies other that the the basic ones
required for ibatis. The one thing i like is that it would be esay to scale up my
up easily by either 1 setting the parameters for my jdbc driver or 2 plugging in 
apache db pooling - nice no change to the app no build - just test and go.

Thanks for the replies.
I think it is just little expensive to create a datasource object and a 
Conn. Pool with 1 connection, When all my code needs is to get a single
connection do some processing and quit. It also means I am dependent on
framework like dbcp for DataSource implementation.

I'm pretty sure dataSource is mandatory (after all, you've got to have 
some kind of source for your data!).  Whenever I've wanted to do what 
you describe, I've just used <dataSource type="SIMPLE"> and set 
<property name="Pool.MaximumActiveConnections" value="1"/>
