rmanリカバリundoテーブル空間
説明:
アナログリカバリundoテーブルスペースの損失とリカバリのプロセス
実験プロセス:
注意:テスト前にデータベースをフルバックアップまたはレベル0バックアップする
完全な準備:
backup database format 'g:\rmanbak\db_%d_%T_%s.bak' plus archivelog format 'g:\rmanbak\arch_%d_%T_%s.bak';
レベル0のバックアップ:
backup incremental level 0 database format 'g:\rmanbak\db_%d_%T_%s.bak' plus archivelog format 'g:\rmanbak\arch_%d_%T_%s.bak';
