In this section, we will learn how to create a pluggable database in oracle 19c using DBCA tool. When you drop a PDB, the control file of the multitenant container database (CDB) is modified to remove all references to the dropped PDB and its data files. If an error is returned during application PDB creation, then the application PDB being created might be in an UNUSABLE state. The current user must be a common user whose current container is the application root to which the application seed will belong. How To.

However, you can drop an application seed. In an Oracle Real Application Clusters (Oracle RAC) environment, the application seed must be closed on all instances. Inside the CDB are two containers: There are no other PDBs created by default in an Oracle database, if youre using the full version of Oracle. There are three types of application common objects: Metadata-linked application common objects store the metadata for specific objects, such as tables, so that the containers that share the application common object have the same structure but different data. Archived logs and backups associated with the dropped PDB are not deleted. A container JDBC data source that can be defined inside the application Server (WebLogic, Tomcat, or others) An Oracle wallet data source that contains the files needed to make the database connection. Therefore, the STORAGE clause is not required. You cannot drop the seed (PDB$SEED). If you are migrating an existing application to the application container, then follow the instructions in.

Prior to 12.1.0.2, when the CDB is started, all PDBs remain in mounted mode. Keeping data files may be useful in scenarios where a PDB that is unplugged from one CDB is plugged into another CDB, with both CDBs sharing storage devices.
