Runtime Troubleshooting (Reference):
Comprehensive troubleshooting guidance for runtime issues, best practices for environment isolation, and solutions to common problems.
Best Practices for Runtime Isolation
1. Use Separate Environments
Working in separate environments for development, testing, and production prevents configuration changes from affecting the runtime environment until tested and deployed.
2. Use Containers
Docker and similar technologies create isolated containers for different solution parts, ensuring modifications in one container don't impact others.
3. Use Version Control
Version control manages solution configurations and code changes, enabling experimentation, rollback capabilities, and change tracking without runtime impact.
4. Use Access Control
Access control mechanisms restrict runtime environment modifications to authorized personnel only, reducing accidental disruptions or unauthorized access.
Troubleshooting Runtime Issues
Troubleshooting Steps
- Review application logs for error messages or warnings
- Use debugging tools to inspect application state at runtime
- Monitor system resources (CPU, memory, disk usage) for bottlenecks
- Consult documentation or support resources for known issues
- Verify appropriate execution profiles for development lifecycle stages
- Test configuration changes before production deployment
- Document custom configurations or modifications
- Keep runtime environment updated with security patches
Common Issues and Solutions
Performance Bottlenecks
Problem: Slow solution execution from inefficient code or inadequate hardware resources.
Solution: Optimize code, allocate more resources, or employ parallel processing techniques.
Configuration Errors
Problem: Incorrect solution configuration settings leading to unexpected behavior or failure.
Solution: Review configuration files, verify parameters, and ensure documentation adherence.
Runtime Environment Mismatch
Problem: Incompatibilities between development and production environments causing runtime issues.
Solution: Ensure consistent dependencies across environments; use containers or virtual machines for isolation.
Module Conflicts
Problem: Conflicts between modules causing unexpected behavior or crashes.
Solution: Check for duplicate or outdated modules; ensure module compatibility.
Database Connectivity Issues
Problem: Connection problems from network issues, incorrect credentials, or misconfigured settings.
Solution: Verify database connection settings, ensure server accessibility, and check credentials.
Client-Side Display Errors
Problem: Issues from incompatible browsers, outdated JavaScript libraries, or misconfigured display settings.
Solution: Ensure browser version support, update libraries, and verify display settings.
Hot Updates Not Applied
Problem: Hot updates not being applied correctly to running solution.
Solution: Confirm solution configuration for online changes; verify update mechanism functionality.
Build and Publish Failures
Problem: Errors during build/publish from incorrect settings, code issues, or dependency problems.
Solution: Review build/publish configuration, fix code issues, and resolve all dependencies.
Troubleshooting by Symptom
| Symptom | Check | Action |
|---|---|---|
| Solution won't start | License status | Verify license validity |
| Slow performance | Resource usage | Monitor CPU/memory |
| Data not updating | Module status | Check device connections |
| Display errors | Browser console | Review JavaScript errors |
| Communication failures | Network connectivity | Test port accessibility |
| Unexpected behavior | Execution profile | Verify correct profile |
Diagnostic Resources
Log Locations
| Component | Default Location | Content |
|---|---|---|
| Runtime | Logs\Runtime\ | Execution events |
| Modules | Logs\Modules\ | Module-specific logs |
| Client | Logs\Client\ | Client connections |
| System | Logs\System\ | System-level events |
Performance Monitoring
Monitor these key indicators:
- CPU utilization per module
- Memory consumption trends
- Network throughput
- Database query times
- Tag update rates
Emergency Response
Severity Levels
| Level | Description | Response Time |
|---|---|---|
| Critical | Production down | Immediate |
| High | Major functionality impaired | < 1 hour |
| Medium | Minor functionality affected | < 4 hours |
| Low | Cosmetic or non-critical | Next business day |
Recovery Procedures
- Assess Impact - Determine scope and severity
- Isolate Problem - Identify affected components
- Apply Fix - Implement solution or workaround
- Verify Resolution - Confirm normal operation
- Document Incident - Record cause and solution
Platform-Specific Issues
Windows Service
| Issue | Solution |
|---|---|
| Service won't start | Check event viewer for errors |
| Permission denied | Verify service account rights |
| Port conflicts | Change port or stop conflicting service |
Linux/Docker
| Issue | Solution |
|---|---|
| Container exits | Check container logs |
| Permission errors | Verify file ownership |
| Resource limits | Adjust container constraints |
