Oracle如何使用備份控制文件

這篇文章主要為大家展示了“Oracle如何使用備份控制文件”，內(nèi)容簡(jiǎn)而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領(lǐng)大家一起研究并學(xué)習(xí)一下“Oracle如何使用備份控制文件”這篇文章吧。

示例一：冷備份所有數(shù)據(jù)文件--->新建表空間--->備份控制文件（日志文件完好）

實(shí)驗(yàn)環(huán)境：

當(dāng)前的控制文件損壞，新創(chuàng)建的表空間損壞，冷備的數(shù)據(jù)文件中沒(méi)有該數(shù)據(jù)文件的備份，但是控制文件和聯(lián)機(jī)日志中有相關(guān)的記錄；由于控制文件損壞，只能使用備份的控制文件來(lái)做恢復(fù)。
