Oracle 18c Express Edition安装失败后残留文件咨询

Hey there, sorry to hear you're stuck with this installation error when trying to set up Oracle 18c XE on your external hard drive. Let's walk through how to fix this and handle any possible leftover files from the interrupted setup.

First, let's restate the error you're seeing for clarity:

"The wizard was interrupted before oracle Database 18c Express Edition could be installed
Your system has not been modified. To complete installation at another time, please run setup again"

Here are the steps you can take to resolve this:

• Check your external drive's connection and permissions
  Make sure the drive is properly mounted and your user account has full read/write access to it. Unstable connections or restricted permissions are common culprits for installation interruptions. On Windows, you can right-click the drive > Properties > Security to verify permissions; on Linux/macOS, use ls -l /path/to/external/drive to check access rights.

• Clean up potential residual files
  Even though the error says your system wasn't modified, the installer might have left partial files on the external drive or in your system's temporary folders:

  • Windows: Open the temporary folder by typing %TEMP% in File Explorer, then delete any folders or files with "Oracle" or "XE" in their names. Also check the root directory of your external drive for an unfinished Oracle folder and remove it if present.
  • Linux/macOS: Clear out Oracle-related files in /tmp, and manually delete any incomplete Oracle installation directories on your external drive.

• Prepare your environment for a successful reinstall

  • Ensure your external drive uses a file system that supports large files (NTFS for Windows, ext4 for Linux, APFS for macOS) — avoid FAT32, which has a 4GB single file limit that can cause issues with Oracle's installation files.
  • Temporarily disable any antivirus software or firewall, as they might block the installer from writing files to the external drive.

• Re-run the installer with proper privileges
  On Windows, right-click the setup executable and select "Run as administrator"; on Linux, use sudo to launch the installer with root privileges. Keep the external drive connected and undisturbed throughout the installation process.
