Enhancing IMS

Version 12 leverages the zEnterprise System


Today's enterprise IT needs are more closely tied to the business than ever before. The business requires efficiency to meet the cost challenges and responsiveness the global economy demands. Enterprise IT must support growth–allowing the business to rapidly develop new products and services to remain competitive, while at the same time increasing productivity and flexibility on demand. Business today also requires IT systems to be resilient, helping reduce business risk and meet regulations and business-processes requirements.

IMS is a powerful database and transaction-management system with significant systems services, built on and exploiting System z processors and operating systems. IMS and System z processors together provide the undisputed leader for mission-critical, operational, enterprise-transaction and data-serving workloads. IMS and its tools, along with System z solutions, have provided investment protection or four decades, and continue to evolve to provide value and meet the business needs of enterprise customers.

IBM has announced version 12, and has added enhancements for IMS 11 users, delivered through the service stream and in new/enhanced tooling.

Leveraging System z Processors

IMS is designed, built and tuned to fully exploit System z processors, taking full advantage of speed and availability improvements, and further enhancing the environment with connectivity and storage-utilization optimization. IMS and System z servers are breaking barriers in scalability.

IMS supports System z10 innovations including high-performance FICON, up to 1.5 TB of real memory, the Infiniband coupling facility links, HiperDispatch support, System z Application Assist Procesors (zAAPs), and Coupling Facility Control Code (CFCC) Level 16 microcode support–reducing IMS Shared Queues global false scheduling. IMS Java can be used with the zAAP processors for reducing costs. This helps reduce the overall cost of computing for Java applications, reduce the demands on general-purpose processors to increase system productivity and make capacity available for other workloads.

IMS 11 Open Database support also provides direct distributed TCP/IP access to IMS data. IMS 11 64-bit storage support reduces extended common storage area (ECSA) demand, optimizing performance/capacity and continuous availability. IMS 11 also eases creation of online recovery points and reduces CPU and elapsed time for IMS databases.

zEnterprise System for Core Businesses

A typical IMS installation runs thousands of core business applications like claims processing, inventory management, package tracking, retail banking and bill-of-materials processing, which all access hundreds of terabytes of key corporate information. In the past, integration of these applications and associated data was primarily done through replication techniques–copying data from one platform to another to allow application access. IMS 11 enables customers to more easily and directly access their IMS data and transactions from any platform. This allows for real-time access to operational data from anywhere, easier application connectivity, integration and reuse, and a significant reduction in costs associated with data replication and redundancy.

Paring IMS 11 with the zEnterprise 196 takes this concept one step further; it enhances connectivity and integration through local high-speed communication channels, which can improve performance, ease management and eliminate the need for additional security previously required on the network. Processing-power improvement means more work. There will also be some CPU reduction for existing workloads.

zEnterprise System enhancements benefit IMS customers in running WebSphere servers with the IMS Resource Adapters or IMS Enterprise Suite on the zEnterprise BladeCenter Extension (zBX) for access to IMS applications and data on z/OS. This connection to and from IMS through local high-speed communication channels should improve performance and manageability, and eliminate the need for additional security for that connection.
