12c – Pluggable Database Üzerinde Point-in-Time Recovery İşlemi

Aslında bu işlemi sadece pluggable database için düşünmemek lazım. Her zaman hata yapılabilir. Eğer bu yapılan hata database’ in sürekliliğini (daha doğrusu tutarlılığını) etkileyecek boyutta ise database hatanın yapıldığı zamanın hemen öncesine dönmemiz gerekebilir. Böylesi bir durumda ne yapabiliriz ona bakıyor olacağız.

Normal restore’ dan farkı point in time recovery ‘ den bashettiğimiz için db’ yi resetlog opsiyonu ile açıyor olmamızdır.

Bir örnek üzerinden gidelim ;

Hangi pluggable db üzerinde çalışıyoruz;

Test için bir test tablosu oluşturalım.

Tablomuzu count edelim. Sonrasında bu bilgi lazım olacak ;

Bu işlemler sonrasında bulunduğumuz noktaki SCN değerimizi alalım;

Tablomuzu yanlışlıkla birinin delete ettiğini varsayalım. (tabi dataya da UNDO’ dan artık ulaşamadığımızı düşünüyoruz);

Data artık yok. Şimdi restore ederek kurtarmaya çalışalım. Öncelikle pluggable database’ imizi kapatalım ;

Restore’ u başlatıyoruz.

İlk restore dememiz de RMAN-06034 hatasını aldık. Bu aslında Oracle 12c nin channel allocate’i ile ilgili bug’ ı her ne kadar restore ederken channel allocate etsenizde bug dan dolayı en az 1 tane channel allocate etmemiz gerektiğini belirtiyor. Şu an için bir fix’ i olmadığı için channel allocate’ leri kaldırıp tekrar deniyoruz;
