Anstatt dies zu tun, würde ich empfehlen, die Zeichensatzinformationen aus der nls_database_parametersAnsicht abzurufen und dann DBCAzum Erstellen einer neuen Datenbank sowie dbms_metadata.get_ddlzum Erstellen des Tabellenbereichs zu verwenden. - Viel einfacher und weniger fehleranfällig. Der Zeichensatz und der nationale Zeichensatz sind wirklich die einzigen Dinge, die sich nur schwer ändern lassen, wenn bereits eine Datenbank erstellt wurde. DBCASie können sie in der Benutzeroberfläche auswählen. Ich kann mir vorstellen, dass Sie einige Skripte packen müssen, um die Erstellung zu automatisieren, oder so?
Wenn Sie wirklich fortfahren müssen, können Sie nicht sofort das tun, was Sie verlangen, aber Sie können CREATE DATABASEdie Steuerdatei sichern , die Ihnen die meisten Informationen liefert, die Sie zum Erstellen einer Anweisung benötigen , einschließlich der meisten pfile-Parameter (Eine pfile ist erforderlich, um eine neue Instanz zu starten, bevor eine CREATE DATABASEAnweisung ausgegeben wird ), Redo-Protokolle und Zeichensätze usw.
Zum Beispiel:
SQL> alter database backup controlfile to trace as '/tmp/db.sql';
Database altered.
SQL> !cat /tmp/db.sql

Anschließend können Sie die DDL zur Erstellung von Tabellenbereichen extrahieren mit:
select dbms_metadata.get_ddl('TABLESPACE', tablespace_name) as ts_ddl
from dba_tablespaces;
