Simulate dates and times to test time-sensitive z/OS applications
Overview
Test applications across time
IBM HourGlass is a clock simulator for testing z/OS applications.
Simulate past, present or future dates and times without changing application code or creating a separate computing environment.
Test time-sensitive applications across time zones and critical calendar events to help identify issues before deployment and improve the reliability of mission-critical applications.
Features
Test with precision and control
- Date simulation
- Test scenarios
- Access control
- Parallel testing
Simulate dates and times
Set past, present or future dates and times for z/OS applications without changing application code, runtime JCL or the system clock.
Create flexible test scenarios
Test end-of-week, month, quarter or year processing, midnight transitions and other critical calendar events. Apply scenarios to individual jobs or multiple programs.
Control testing access
Manage access to test scenarios by programmer, job group or class while supporting users with online guidance throughout the Control Center.
Run tests simultaneously
Run concurrent tests with different system dates while maintaining an independent date and time view for each user or application environment.
Use cases
Time-based testing in action
Validate application behavior at the end of a week, month, quarter or year without waiting for the actual calendar event.
Test date and time functions across time zones to help maintain consistent application behavior in global operations.
Set dates and times for CICS applications, transactions and regions to validate time-dependent processing in CICS environments.
Specifications
System requirements
Software requirements
IBM HourGlass requires:
- a supported IBM z/OS environment; z/OS 2.5 or later
- an APF-authorized library from which to activate the software
System resources
Installing all options requires approximately 185 KB of available Extended Common Service Area. Resource requirements may vary depending on the selected configuration options.
