Look for lines about "Message File Path" or "MESG directory resolution."

Summary

Reproduction steps (assumed)

Diagnosis checklist (ordered)

  • Locate expected message file(s)
  • Check file permissions
  • Validate version compatibility
  • Inspect environment and config
  • Examine installer and startup logs
  • Test with default locale
  • Reinstall or repair

    • Suggested fixes (concise)

  • Correct configuration pointing to message file path or LOCALE settings.
  • Fix permissions (e.g., sudo chown / chmod) so the service user can read message files.
  • Ensure no mixed versions: uninstall older components before installing new.
  • If installed from source, re-run build/installation steps to generate and install resource files.
  • Check for antivirus or system policies that may have quarantined resource files.

    Error ID: REP-0001
    Title: Report Builder Message File Not Found

    Message:

    REP-0001: Unable to find the Report Builder message file. Please verify your installation.

    Set temporarily:

    set REPORTS_PATH=%ORACLE_HOME%\reports\mesg

    Or include multiple paths:

    set REPORTS_PATH=%ORACLE_HOME%\reports\mesg;%ORACLE_HOME%\reports\sql
