1. 报错详细信息
安装 Oracle 过程中,在执行 “先决条件检查” 时报错:
报错内容:
This test checks whether the length of the environment variable "PATH"
does not exceed the recommended length
详细信息:
Environment variable: "PATH" - This test checks whether the length of the environment variable "PATH" does not exceed the recommended length.
预期值: 1023
实际值: 1123错误列表: PRVF-3929 : Adding the Oracle binary location to the PATH environment variable will exceed the OS length limit of [ "1023" ] for the variable on the node "Hare" Cause: The installer needs to update the PATH environment variable to include the value "%ORACLE_HOME%/bin;". However, doing so will cause PATH to exceed the maximum allowable length that this operating system allows. Action: Ensure that the sum of the lengths of your current PATH environment variable and that of "%ORACLE_HOME%/bin;" does not exceed the operating system limit. Restart the installer after correcting the setting for environment variable.
2. 解决方案
提示信息的意思就是环境变量过长。
2.1 方案一:修改配置文件cvu_prereq.xml
cvu_prereq.xml
文件在 oracle 解压包 database\stage\cvu
目录下。打开文件,找到 CERTIFIED_SYSTEMS
标签,找到自己电脑对应的系统,将标签内的 MAX_LENGTH
的值改成较大的值(大于报错提示信息中的值即可)如下:
注意:
- 如果改完不生效,就把所有的 MAX_LENGTH 值都改掉;
- 修改完成后,重新扫描也不会生效,需要退出后重新安装。
2.2 方案二:修改环境变量配置
- 新建系统变量Path1
- 将Path中的环境变量复制到Path1
- 删除Path中的变量,添加以下内容:%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%Path1%
- 点击确定保存更改
- 回到安装界面点击重试即可
Tips:
方案一只能解决安装 Oracle 过程中出现的环境变量过长的问题,安装 Oracle-Client 过程中可能也会出现同样的报错,这时候需要用方案二解决。
