DataDirect's Shadow z/Events
View PDFData is both constant and ever-changing across any global enterprise. Mainframes are often considered the system of record for data. DataDirect Shadow provides a real-time link between mainframe and distributed databases, to allow organizations to use business meaningful data changes for business intelligence, Complex Event Processing (CEP) and event-driven architectures. Built into Shadow is unique, patent-pending technology that exploits the zIIP specialty engine to lower mainframe Total Cost of Ownership (TCO). Almost all processing done by Shadow z/Events can be diverted from the mainframe General Purpose Processor to the specialty engine, thereby reducing MSU utilization. With Shadow z/Events you get the interoperability benefits of XML without additional processing costs. Shadow opens up the zIIP to an expanded range of databases for change data capture, including DB2, IMS, VSAM, IAM, Adabas, and IDMS. As mainframe enterprises increasingly embrace the concept of real-time event integration - particularly within the context of SOA - business requirements (and for that matter, BPM and BAM initiatives) dictate the need for detecting and reacting to complex patterns comprised of multiple events. By capturing mainframe-based events in real-time, Shadow ensures not only a lower TCO for the mainframe, but also more streamlined integration within the context of SOA.
Product Description

Shadow z/Events is a complete facility for the capture and publication of events (state changes) that occur within mainframe databases. No product on the market offers the precision and range of Shadow z/Events when it comes to mainframe database sources, capturing events in real-time from DB2, VSAM, IMS/DB, CA-IDMS, or Adabas. Once captured, the event is transformed into XML and "pushed" asynchronously via multiple messaging and communication protocols such as WebSphere MQ or HTTP/HTTPS.
Shadow z/Events is non-invasive and accomplishes its event capture and publication without touching the database code or data, eliminating any chance of data corruption or database downtime. Shadow z/Events is an important component in implementing the Real-Time Enterprise and in combining EDA and Service Oriented Architecture in what is being called advanced SOA, or SOA 2.0.
Key Features
- Non-invasive - Event "listeners" require no changes to mainframe application code
- Real-time - Operates in real-time, reducing latency and expenses associated with traditional batch processing
- Complex Event Processing (CEP) - Allows the Shadow mainframe event manager to logically evaluate multiple events, enabling decoupled, parallel, asynchronous application processing
- Transactional integrity - Events are detected and logged 24x7. All events are embedded within the application Unit of Work and are never processed until the Unit of Work has been committed, ensuring transactional integrity of the event
- Event enrichment - Tagged events can be enriched to include contextual information and event details, transforming an innocuous technical state change into an event with increased business meaning
- Transformation - Captured mainframe events are transformed into XML to facilitate utilization with a broad range of distributed application environments and databases
- Support for Log Based Capture - events within ADABAS and DB2 can be captured non-invasively through process of their logs
Realize the Benefits of the Real-Time Enterprise
Shadow z/Events is the enabling technology to allow the mainframe to drive heterogeneous business processes and maintain real-time data consistency across your enterprise. Tremendous value lies in discovering and understanding the complex patterns of business events in a real-time fashion, allowing critical business decisions to be made and sophisticated automation to be implemented. No where does this opportunity for the realizing the potential of the real-time enterprise present itself than within the highly transactional world of mainframe computing.
