Oracle patch也即是Oracle補(bǔ)丁。Oracle補(bǔ)丁又包含好幾個(gè)種類，小的補(bǔ)丁簡(jiǎn)直是難以數(shù)計(jì)，難免讓人眼花繚亂。盡管如此，Oracle patch還是有序可循的。而且Oracle提供的opatch工具非常方便的用于安裝oracle patch，以及查看當(dāng)前系統(tǒng)已經(jīng)安裝的patch。本文列出了patch的幾種類型，以及主要描述通過(guò)opatch工具查看當(dāng)前數(shù)據(jù)庫(kù)的patch應(yīng)用的情況。對(duì)于如何apply patch可參考Oracle官方文檔。
