يا ريت لو في حدا الinstance recovery

وشكراً

انا بالانتظار

If the database was last closed abnormally, either because the database administrator terminated its instance or because of a power failure, then Oracle automatically performs recovery when the database is reopened.

جزاك الله خيراً

if u shutdown the database with the commande shutdown abort then when you started it up, oracle do an instance recovery, and the startup will take more times
