One of the great features it to make use of the command-line option available with the oracle tools, like runInstaller, asmca, netca, dbca etc., especially when no X environment is available.

Below are several examples on how to manage pluggable database instances using the DBCA in silent mode for the Oracle RDBMS 12c.

To list all the possible option you first need to execute: dbca -help. This will display the command options, for more details about each command you need to define dbca <command> -help.

$ dbca -help



[-silent | -progressOnly] {<command> <options> } | { [<command> [options] ] -responseFile <response file > } [-continueOnNonFatalErrors <true | false>]

<command> :












Enter “dbca -<command> -help” for more option

Create a pluggable database

There are several option when you want to create a pluggable database using the command line. The default, which is the pdb$seed, rmanbackup, metadatafile (if unplugged). The example will display the default one. Including the creation of the PDB admin user.

$ dbca -silent -createPluggableDatabase -sourceDB cdbprod -pdbName pdbprod -createPDBFrom default -pdbAdminUserName pdbadmin -pdbAdminPassword oracle -createUserTableSpace true

Unplug a pluggable database

The unplug will remove a PDB from the defined container database and create as default a tar.gz file in the location: /u01/app/oracle/product/12.1.0/dbhome_1/assistants/dbca/templates

$ dbca -silent -unplugDatabase -sourceDB cdbprod -pdbName pdbprd -PDBMetadatafile /tmp/ -archiveType none

2)alter system flush buffer_cache inst=0 container=3 local;

3)drop pluggable database <name> including datafiles

$ dbca -silent -deletePluggableDatabase -sourceDB cdbprod -pdbName pdbprod
