Bonjour à tous,

je rencontre un probleme pour moi insoluble (mes connaissances sont limitées en debug )
La machine sur laquelle tourne mon instance Oracle (10g sur une RedHat AS3.3) a reboot froidement pendant un arret de l'instance .
Apres ce reboot. Oracle m a mis le message (titre du sujet)

je vous mets Alert_log de cette instance. Si qqun pouvait me guider vers un debut de solution ...
Merci par avance
Fa
Edit: j'ai un Backup de la DB (130Go) au cas ou, mais j' aimerais connaitre la maniere de resoudre ce prob
