IMS

In today’s business and economic environment, IT organizations must reduce costs while supporting business objectives. Mergers, acquisitions, regulatory requirements, globalization, and more can turn that directive into a moving target. The demands of the business are paramount. The demands on the IT organizations are equally critical. IT growth must enable the business to grow and remain competitive. IMS 12, built on the rock-solid System z platform, brings the target into view and helps you address these challenges. Together, IMS 12 and IMS Tools are a great fit for the future.

IMS performance is already legendary. In IMS 12, we have improved performance even more--double-digit gains! Clients can expect to see 60% faster access to IMS data using Fast Path Secondary Indexing. Database Administrators can see 50% faster deployment of IMS resource definitions and database changes using IMS Explorer. The redesigned IMS 12 WADS showed improvements in response time of up to 10%, and SAM striping can significantly improve logger capability, improve throughput, and reduce batch and BMP windows. IMS 12 is faster than ever!

Clients who have depended on IMS for decades can continue to derive value with the expanded integration of IMS across IBM’s portfolio. IMS Tools support IMS 12 from Day 1. Rational Developer for System z provides the best platform for IMS 12 application program development and maintenance. IMS applications can send business event data to business event processing and monitoring engines such as IBM WebSphere Business Events and IBM Business Monitor. IBM InfoSphere IMS Replication for z/OS helps increases the availability of IMS data, whether it is for a continuous availability strategy, or by ensuring the timely distribution of critical enterprise information. IMS clients can monitor database activity and protect sensitive data using IBM InfoSphere Guardium Data Encryption for DB2 and IMS Databases. Threadsafe access between CICS V4.2 and IMS means that EXEC DLI and CALL DLI calls from CICS can now be made without any TCB switching overhead, providing CPU savings and increased throughput for IMS DBCTL clients.

With the introduction of IMS Enterprise Suite Explorer, clients can expect to see up to 50% faster deployment of IMS resource definitions. The IMS Catalog offers a trusted and comprehensive view of IMS database metadata and is fully managed by IMS. The catalog minimizes the risks of unexpected dependencies between IMS resources, and significantly aids new application development, delivering enhanced simplification, integration, and scalability. The Universal JDBC and DLI drivers and the Universal DB resource adapter provide further database simplification and flexibility. The IMS Repository support for selected DRD resources (transaction, routing codes, program directories, database directories, and descriptors for these) provides a single centralized store for resource definitions in an IMSplex, simplifying the management of resource definitions.
