Creating CICS Web Services
Do More with your Mainframe
James Alexander, Director of Technical Services
“With CICS processing
more transactions
per day than the
entire WWW,
organizations must
continue to utilize
the transactional
capabilities within
CICS”

Traditional Screen-Scraping Approach
Scales Poorly
Breaks Easily
Poor Performing

HostBridge for zIIP
• System z Requirements
– z9, z10, zEnterprise (and future models)
– z/OS 1.10+ (any supported version)
– zIIP Processor
• HostBridge Requirements
– HostBridge V6.6+
– CICS TS 3.1+
– Scripts run on HB v6+ Process Automation Engine (“HBJS”)
• Bottom Line
– 100% of HB Base product requests run on the zIIP
– 100% of HB JavaScript engine runs on the zIIP
– 100% of customer written scripts run on the zIIP
– 0% of existing CICS apps run on the zIIP (that’s a good thing)
