Plutôt que de le faire, je vous conseille d'obtenir les informations sur le jeu de caractères de la nls_database_parametersvue, puis de les utiliser DBCApour créer une nouvelle base de données, ainsi que dbms_metadata.get_ddlpour gérer la création d'espace disque logique. - Beaucoup plus facile et moins sujet aux erreurs. Le jeu de caractères et le jeu de caractères nationaux sont vraiment les seules choses qui sont difficiles à changer lorsqu'une base de données a déjà été créée et DBCAvous permet de les choisir dans l'interface utilisateur. J'imagine que vous avez besoin d'emballer des scripts pour automatiser la création ou quelque chose?
Quoi qu'il en soit, si vous devez vraiment continuer, vous ne pouvez pas faire exactement ce que vous demandez, mais vous pouvez vider le fichier de contrôle qui vous donnera la plupart des informations dont vous avez besoin pour construire une CREATE DATABASEinstruction, y compris la plupart des paramètres de pfile (un fichier pf est requis pour démarrer une nouvelle instance avant d'émettre une CREATE DATABASEinstruction), refaire les journaux et le jeu de caractères, etc.
Par exemple:
SQL> alter database backup controlfile to trace as '/tmp/db.sql';
Database altered.
SQL> !cat /tmp/db.sql

Ensuite, vous pouvez extraire le DDL de création d'espace disque logique avec:
select dbms_metadata.get_ddl('TABLESPACE', tablespace_name) as ts_ddl
from dba_tablespaces;
Si vous souhaitez que je développe davantage toutes les étapes requises pour créer manuellement une base de données, il suffit de demander (si vous ne le savez pas déjà).
