see alert log for more information
post here alert log file entry

Found on net
Cause: If you enable automatic SGA Management by setting SGA_Target >0 and
if you are using db_block_buffers(Obsolete parameter) in your init.ora.
Startup of Database fails with ORA-00824 Error

Remove "db_block_buffers" parameter in your init.ora file and startup your database.

Démarre le contenu du fichier à partir du début du startup et supprime la partie shutdown inintéressante.
Il doit y avoir la même erreur ORA-00824 dans le fichier.

je crois que l'erreur vient de :
Cannot set sga_target with db_block_buffers set

alors question :
quelle valeur dois-je attriber a DB_BLOCK_BUFFER ?
et ou dois-je le faire?

Tu ne dois pas mettre ce paramètre.
A la rigueur tu peux mettre le paramètre db_cache_size mais je te le déconseilles, laisse faire Oracle.

Cordialement,
Michel
