cmd卸載oracle

李明濤1年前7瀏覽0評論

在使用Oracle數據庫的過程中,有時需要卸載某個版本的Oracle數據庫。當需要卸載Oracle時,可以通過命令行工具cmd來完成卸載操作。

在卸載Oracle之前,首先需要檢查一下本地計算機上是否有Oracle數據庫實例。可以通過在命令行窗口下輸入以下命令來查看本地計算機上是否存在Oracle實例:

lsnrctl status

如果該命令返回類似以下輸出:

LSNRCTL for 64-bit Windows: Version 12.2.0.1.0 - Production on 16-JUL-2021 15:09:08

則說明本地計算機上存在Oracle實例。在卸載Oracle之前需要先停止數據庫實例??梢酝ㄟ^在命令行下輸入以下命令來停止Oracle實例:

net stop OracleServiceXE

其中OracleServiceXE為Oracle數據庫實例的服務名。

接下來可以通過在命令行下輸入以下命令來卸載Oracle數據庫:

setup.exe -silent -deinstall -nowait -responseFile "C:\Oracle\product\12.2.0\dbhome_1\deinstall\deinstall.rsp" ORACLE_HOME="C:\Oracle\product\12.2.0\dbhome_1"

其中C:\Oracle\product\12.2.0\dbhome_1為Oracle數據庫的安裝目錄。

通過以上命令可以完成Oracle數據庫的卸載操作。

總的來說,在卸載Oracle數據庫之前,需要先檢查本地計算機上是否存在Oracle實例,并且需要先停止Oracle實例,然后才能通過命令行工具cmd來卸載Oracle數據庫。
