renommer le nom d'une base de donnees

[boussafi]

bonjour;

C'est utile de modifier nom d'une base de donnees c'est pour ca j'ai pense a decrire comment le faire.
voici check list pour renommer une base de donnees:
tout d'abord il faut que tu soit un administrateur.
1. pour savoir le nom de la base

Code :

SQL> SELECT name FROM v$database;

2. pour faire sortir la trace de la base de donnees

note:on supprime tous les fichier trace de C:\oracle\admin\nom_de_la_base\udump si tu n'as pas besoin d'eux.

Code :

1
2
SQL> ALTER system switch logfile; 
SQL> ALTER DATABASE backup controlfile TO trace;

le fichier trace a cette structure

4. On remplace pour executer le nouveau script

Code :

CREATE CONTROLFILE REUSE DATABASE "old_db_name" RESETLOGS  NOARCHIVELOG

par
[CODE]CREATE CONTROLFILE SET DATABASE "New_db_name" RESETLOGS NOARCHIVELOG
et on supprime laligne

Code :

note: on ne change aucun chemin.

6. on arrete la base de donnees

Code :

SQL> shutdown

7. on supprime les fichier de control de la base.

8. on change le nom de la base de donnees dans le PFILE et/ou SPFILE

9. on lance le script qu'on a prepare.

10. on verifie le nom de la table

Code :

SQL> SELECT name FROM v$database;

enfin... c'est sympa d'avoir pensé au forum pour faire un document complet

[pholos]

bonjour à tous,

c'est bien gentil tout ça mais dans tous les posts que vous citez personne ne pense à changer les noms de repertoire qui portent toujours l'ancien nom d'instance...

pas tres propre tout ca.

ne vaudrait-il pas mieux dans ce cas créer une nouvelle instance?

[orafrance]

rien n'empêche de modifier le nom du répertoire dans le script de création du controlfile pourvu que les datafiles aient été copié convenablement
