ColdFusion 2025 Frequently Asked Questions

ColdFusion 2025 includes several major improvements:

• Tomcat 10.1 - Upgraded servlet container with Jakarta EE support
• JDK 17 LTS - Long-term support Java runtime with performance improvements
• ColdFusion Package Manager (cfpm) - Modular installation system
• Enhanced Security - Improved lockdown tools and secure defaults
• Performance Monitoring - Better observability and metrics
• Modernized REST APIs - Enhanced API capabilities

ColdFusion 2025 requires JDK 17 (LTS) or later. Adobe recommends using the latest JDK 17 patch release for optimal security and performance.

Download the appropriate JDK from:

• Oracle JDK 17 (requires license for production)
• Eclipse Temurin OpenJDK 17 (free, recommended)
• Amazon Corretto 17 (free, AWS-optimized)

The recommended approach is to allocate 50-70% of available system RAM to the JVM heap. For production servers:

• Minimum: 4-8GB for production workloads
• Optimal: Scale based on actual memory usage patterns
• Measurement: Use monitoring tools to track real usage
• Adjustment: Start conservative and increase based on metrics

See the JVM & Tomcat Tuning Guide for detailed sizing guidance.

Yes, ColdFusion 2025 is fully containerizable:

• Official Docker Images: Adobe provides Docker images for ColdFusion 2025
• Stateless Deployments: Supports externalized configuration and session management
• Kubernetes Ready: Works with container orchestration platforms
• Cloud Native: Suitable for microservices architectures

Learn more in the Containerization Guide.

CFPM is a command-line tool for installing and managing ColdFusion packages and features:

• Modular Installation: Install only required components
• Reduced Attack Surface: Disable unused features
• Dependency Management: Automatic resolution of package dependencies
• Package Repository: Access to Adobe's package ecosystem

See the CFPM Package Management Guide for usage instructions.

Follow this update schedule:

• Security Updates: Apply immediately (within 48 hours)
• Cumulative Updates: Test in staging within 30 days
• Production Deployment: Deploy within 60 days of release
• JDK Updates: Keep JDK current with latest patches

Subscribe to Adobe Security Bulletins for critical patches.

Essential security hardening steps:

1. Run Lockdown Guide: Execute the Adobe ColdFusion 2025 Lockdown Guide
2. Disable Unused Services: Remove unnecessary features via cfpm
3. Configure Web Server Connectors: Properly secure connector endpoints
4. Implement IP Restrictions: Limit admin access by IP
5. Enable Secure Profile: Use production secure settings
6. Strong Session Management: Configure secure session cookies
7. Regular Updates: Keep all components current

See the Security Baseline Guide for comprehensive hardening.

Yes, migration is supported with proper planning:

• Code Analyzer: Use Adobe's Code Analyzer to identify compatibility issues
• JDK 17 Changes: Review Java compatibility for JDK 17
• Tomcat 10.1: Test with Jakarta EE namespace changes
• Staging Environment: Thoroughly test before production deployment
• Incremental Migration: Consider phased approach for large applications

ColdFusion 2025 supports multiple monitoring solutions:

• FusionReactor: Real-time performance monitoring and debugging
• SeeFusion: ColdFusion-specific metrics and analysis
• New Relic: APM with ColdFusion agent support

• PostgreSQL
• Microsoft SQL Server
• Oracle Database
• IBM DB2

Best Practice: Always update to the latest JDBC drivers from database vendors for security patches and performance improvements.

See the Datasources & JDBC Guide for configuration details.

Key optimization steps:

• JVM Heap Sizing: Allocate appropriate memory based on usage
• Caching Strategies: Enable template cache, query cache, and object caching
• Connection Pooling: Configure datasource pools correctly
• Request Throttling: Limit concurrent request processing
• Trusted Cache: Enable in production for faster template execution
• Monitoring: Implement performance monitoring from day one
