oracle ADR

自 Oracle Database 11g 發行版 1 起，所有跟蹤、意外事件轉儲和程序包、預警日誌、健康狀況監視報告、核心轉儲等文件都存儲在 ADR 這一基於文件的資料檔案庫中，以提供數據庫診斷數據。它對多個實例和多種產品使用一個統一的目錄結構，並存儲在任何數據庫之外。其位置由 DIAGNOSTIC_DEST 初始化參數設置。如果省略該參數或將其留空，則數據庫在啓動時按如下所示設置 DIAGNOSTIC_DEST：如果設置了環境變量 ORACLE_BASE，DIAGNOSTIC_DEST 會設置爲 $ORACLE_BASE。如果未設置環境變量 ORACLE_BASE，DIAGNOSTIC_DEST 會設置爲 $ORACLE_HOME/log。

adrci命令可用於管理ADR下相關日誌，.trc,.trm文件不再需要手動或寫腳本去定時清理，使用adrci即可實現自動清理：

[oracle@prodb ~]$ adrci
