Referencing MySQL databases
The last step is to configure the data sources that the application is going to use at WebLogic, and create links to these databases at Eclipse. This kind of connection is a data source (DS) inside WebLogic Server.
Tip
In earlier versions of WebLogic Server, you were supposed to configure both a connection pool and a data source. Now, both concepts are contained within a data source, which is a logical move—sharing a pool of connections but not the link to it (the data source) may lead to problems, since no application could predict if others were using the underlying pool, and worst yet, how.
Creating WebLogic data sources
As we just finished enabling the domain at Eclipse, we can start the server from there:
In the Servers tab, right-click on the domain name and then Start from the context menu, or if you prefer to start it manually, OEPE will synchronize to show that the server is up and running.
