Okay here in the Oracle Forums are a lot of people who can and will help you to do your DBA job.
I can't follow your question? What do you mean by "Started with the developerday"?
May be a virtual machine which can be downloaded from the OTN website.
If it is a Image for a virtualbox so you can import this image and start it. normally there is a readme or another document which
describes the user and password are used for this image.
If it is another template then you need to setup an Oracle VM Server and Manager environment to use the VM templates.
If you are using the oracle developer days virtual appliance, the login to Oracle Linux is oracle/oracle.
It then displays the following banner:
All passwords are oracle or noted if otherwise.
The SQL Developer and Data Modeler scripts are in the directory:

I cannot find a readme file for it.
For anyone else thinking of using this appliance, the OTN page is http://www.oracle.com/technetwork/database/enterprise-edition/databaseappdev-vm-161299.html
