自 Oracle Database 11g 發(fā)行版 1 起，所有跟蹤、意外事件轉(zhuǎn)儲(chǔ)和程序包、預(yù)警日志、健康狀況監(jiān)視報(bào)告、核心轉(zhuǎn)儲(chǔ)等文件都存儲(chǔ)在 ADR 這一基于文件的資料檔案庫(kù)中，以提供數(shù)據(jù)庫(kù)診斷數(shù)據(jù)。它對(duì)多個(gè)實(shí)例和多種產(chǎn)品使用一個(gè)統(tǒng)一的目錄結(jié)構(gòu)，并存儲(chǔ)在任何數(shù)據(jù)庫(kù)之外。其位置由 DIAGNOSTIC_DEST 初始化參數(shù)設(shè)置。如果省略該參數(shù)或?qū)⑵淞艨?#xff0c;則數(shù)據(jù)庫(kù)在啟動(dòng)時(shí)按如下所示設(shè)置 DIAGNOSTIC_DEST：如果設(shè)置了環(huán)境變量 ORACLE_BASE，DIAGNOSTIC_DEST 會(huì)設(shè)置為 $ORACLE_BASE。如果未設(shè)置環(huán)境變量 ORACLE_BASE，DIAGNOSTIC_DEST 會(huì)設(shè)置為 $ORACLE_HOME/log。

adrci命令可用于管理ADR下相關(guān)日志，.trc,.trm文件不再需要手動(dòng)或?qū)懩_本去定時(shí)清理，使用adrci即可實(shí)現(xiàn)自動(dòng)清理：
