There are two databases that can be used with the Web logic J2EE connector architecture and these databases are as follows:
1. Cloudscape database:
This is the default database that is used with the architecture and this consists of the samples that contain the resource adapter representing the database system. The configuration of this is set in weblogic-ra.xml file that contains the cloudscape datasource.
2. Oracle database: The settings of cloudscape can be replaced by oracle settings. The resources that are provided consist of the JDBC support, hence it can use any database for which the resources can be configured and represented.
