What does this entry specify?

  • A An on-premise data source named DBaaS is configured for use by the application, but not when deployed to the cloud
  • B An on-premise data source named DBaaS is configured for use by the application that is deployed to the cloud
  • C An Oracle Database Cloud – Database as a Service instance named DBaaS is configured for the Oracle Java Cloud Service instance
  • D An Oracle Database Cloud – Database as a Service instance named DBaaS is configured as a data source for the application deployed to the cloud
Explanation

A resource-description in weblogic.xml maps the resource reference used by a web application to the JNDI name of a server resource, such as a JDBC data source. Mapping DBaaS to DBaaS therefore makes the DBaaS data source available to the application deployed in Oracle Java Cloud Service.
