- Change passwords in group_vars/all.yml to clear text (Oracle123, Grid123)
- Use password_hash('sha512') filter in users_configuration.yml for automatic hashing
- Maintain same security level but with more readable and maintainable passwords
- Passwords are hashed automatically during playbook execution
- Add oracle_user_password and grid_user_password to group_vars/all.yml
- Update users_configuration.yml to use password variables instead of hardcoded hashes
- Enable centralized password management for system users
- Keep passwords as clear text variables (no encryption needed for this use case)
- Add dbhome variable to group_vars/all.yml for consistency
- Remove duplicate Oracle variables from oracle-db-install defaults
- Standardize oracle_home definition across all roles
- Keep only role-specific variables in individual role defaults
- All common variables now centralized in group_vars/all.yml
- Extract common Oracle variables from role defaults to group_vars/all.yml
- Variables are now shared across all roles without duplication
- Maintains backward compatibility with existing role defaults
- Follows Ansible best practices for variable organization
