Creating datasource and Closing connection?

[scott miles]

1)When we get a connection using datasource say oracleDatasource .
Lets say during programming, some developer does not close the connection
explicity. Will that connection be returned to connection or will it
be considered as connection leak.

2) As it is said , datasource is created, deployed, and managed separately(by appserver) from the applications that use it. There are two ways in which we can create datasource
A) From appserver admin console. (I understand that datasource can be managed by appserver here)
B) Second way is to create datasource in your pragramme like Datasource ds = new OracleDataSource(); But how will datasource be managed by appserver asi n this case as we are creating it in our programme.

1) While the connection will eventually be returned to the pool, it is still a connection leak. It takes time for the connections to be returned and you can run out in the meantime.

2) A datasource created in the code will not be managed by the server. It's useful for testing, but better to define the datasource more globally in real code.
