When you create an application seed using the AS SEED clause of CREATEPLUGGABLEDATABASE, you do not specify its name. An error is returned if you attempt to open the application seed in read-only mode. When that is complete, any PDBs created using the application seed have the applications installed. In an Oracle Real Application Clusters (Oracle RAC) environment, the application seed must be closed on all instances. This will change your connection to the pdb1 database, which is a pluggable database. If you are migrating an existing application to the application container, then follow the instructions in. If not then manually delete them. You can check an application seeds state by querying the CDB_PDBS or DBA_PDBS view, and you can learn more about application seed creation errors by checking the alert log. You can also remove application seeds from application containers. The current user must be a common user whose current container is the CDB root. An application container is usable only when it is plugged into a CDB. . To unplug an application seed, connect to its application root and use the ALTER PLUGGABLE DATABASE statement to specify an XML file or a .pdb file. When you issue this statement, Oracle Database drops the database and deletes all control files and data files listed in the control file. If an application container was created with the SNAPSHOT COPY clause, then you must specify INCLUDING DATAFILES when you drop the application container. The application container name is used to distinguish an application container from other containers in the CDB. Starting with 12cR2, the local undo mode was introduced, meaning that each PDB has their own UNDO tablespaces. The application seed is cloned from the root of the application container. SQL> drop tablespace tbs01 including contents and datafiles; Tablespace dropped. We can see the root container, the seed PDB, and the default PDB (called xepdb1) that comes with the database. RMAN> run. To drop a traditional PDB or an application container, the current container must be the root, you must be authenticated AS SYSDBA or AS SYSOPER, and the SYSDBA or SYSOPER privilege must be either granted to you commonly, or granted to you locally in the root and locally in traditional PDB or application container you want to drop.

The FILE_NAME_CONVERT clause is required to specify the target locations of the copied files. After Oracle 12c and the CDB/PDB functionality, the information shown in each of these types of views was different. An Oracle CDB has many containers. Example 12-9 Creating an Application Seed From an Application Root. If you omit the ENABLE PLUGGABLE DATABASE, then this new database is a non-CDB, and can never be changed to contain PDBs. For example, an application seed in the salesact application container must be named salesact$SEED. I have the backupsets and the controlfile autobackups, but don't know how to get RMAN to pick that file. Such a backup provides a convenient way to archive the unplugged application seed in case it is needed in the future. Updated My database is not mounted and I tried to mount it and shows the below error details. You cannot roll back a DROP PLUGGABLE DATABASE statement. If this user was not granted administrator privileges during application seed creation, then use the SYSandSYSTEMcommon users to administer to the application seed.

The user must exercise the privilege using AS SYSDBA or AS SYSOPER at connect time. Videos | In SQL*Plus, ensure that the current container is the application root of the application container to which the application seed belongs. Step3:-We will see output.

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. Data Files Data Dictionary Views A set of data dictionary views provides useful information about the data files of a database. INCLUDING DATAFILES removes the data files from disk. The temp file for the PDB is also deleted. Conversion of a non-CDB database to a pluggable database involves getting a description the non-CDB database and using this to plug it into a CDB as a new PDB.

You can also remove application containers from a CDB, and you can remove application seeds from application containers. Multitenant : All Articles The following statement drops the PDB pdb_name and it will remain its associated data files: 0. 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. Mount the database in exclusive restrict mode. Given the preceding factors, the following statement creates the application seed from the application root, opens the application seed, switches containers to the application seed, runs the pdb_to_apppdb.sql script to convert the application root to an application PDB, closes the application seed, and opens the application seed in open read-only mode: The application seed was created from the application root.
