CICS Integration, Web Services, HostBridge, zIIP

Modernizing CICS and z Systems with Web Services/ SOA

Whether you’re presenting legacy apps through a full-featured Web interface or integrating with distributed systems to improve business interoperability, standards-based Web services/SOA remains the express bridge to doing more at lower cost with CICS and mainframe data assets.

An Object Oriented Approach to Modernizing Complex CICS Applications

Using the HostBridge JavaScript Engine, a large organization simplified complex legacy applications and integrated them with modern enterprise-wide systems. Their object-oriented approach enabled them to transform CICS screens into reusable modules called from dynamic assembly-level web services.

zIIP-Enabling CICS® Integration Workloads: HostBridge for zIIP

With HostBridge for zIIP, organizations can run 100% of their CICS integration/SOA workloads on the lower-cost zIIP, deferring capacity upgrades, often improving processing performance, and reducing processing costs and mainframe TCO.

Composing CICS Services: A HostBridge White Book

Get the big picture on CICS services composition. This white book answers essential why, where, and how questions about composing business/web services to integrate CICS.

Where CICS Services Are Best Composed

When writing Web services for CICS applications, organizations must decide where to do so – in the middle tier, on the mainframe but outside CICS, or inside CICS. This excerpt from the Composing CICS Services white book shows how some configurations are better than others.

SOAP and REST: Choosing Formal or Informal Web Services for CICS Integration

CICS supports SOAP and REST for integrating transaction data. What are they? When should you use them? Why should you care? Read our white paper.

SOA Integration for CA Mainframe Resources

Service-oriented architecture (SOA) and web services integration continue to provide organizations with opportunities to do more with existing information resources while reducing cost and complexity. This is especially true for mainframe resources.

HostBridge Socket Optimization

How to Optimize CICS Socket Applications and Cut Costs

A customer with high-volume socket applications asked for help reducing CPU burn and saving MIPS. This Letters from the Trenches white paper describes our performance testing and solution – HostBridge Socket Support.

Socket II: Optimizing CICS Socket Processes for a Financial Industry IT Provider

A customer who has very high volume CICS transaction during a four hour peak on the first of each month asked if HostBridge could maximize their system performance. Using HostBridge Socket Support, the customer saw a significant reduction in GP CPU time during those peak hours.
