Clerity Mainframe Rehosting Reference Architecture

The Clerity MFRRA is built upon several key criteria that Clerity considers essential to the design, deployment and maintenance of any successful IT implementation. Today's enterprise solutions must address the standards IT-orientated businesses have come to expect - standards which include enabling flexible functionality, high availability, scalable performance and extensibility.

Mainframe application environments typically utilize a wide-range of infrastructure tools and utilities. Therefore, the Clerity MFRRA places considerable emphasis on demonstrating how these third party tools and utilities can be deployed in a Clerity Mainframe Rehosting environment.

Clerity UniKix TPE and UniKix BPE software can be utilized in conjunction with a large variety of third party products to support a complete enterprise. The third-party infrastructure products table highlights a partial list of such products, sorted by functional area. Many of the functional areas contain multiple product listings. These options illustrate the flexibility and choice available in Clerity's mainframe rehost framework. Using this guide as a reference, one can choose the particular products within a functional area that meet individual cost, functionality, vendor preference, or technical needs.

The tables below present a list of Clerity solutions that were selected for the MFRRA. It must be noted that this is not a definitive list of supported solutions, merely a list of solutions selected for the MFRRA.

Clerity Service Builder SOA Enablement Expose any 3270 based transaction (UniKix TPE, IBM CICS, IBM IMS) as Web Services. Clerity Web Connect Web Enablement Web Enable any 3270 based transaction (UniKix TPE, IBM CICS, IBM IMS). 3270 Pathway software Development tool Provides the ability to create Java beans which can be used to extract and manipulate data from 3270 based systems.

The Clerity MFRRA serves as a recommended configuration that can be tailored to meet the specific requirements of any enterprise by leveraging the openness, scalability, and flexibility of the solution. For instance, systems may be configured redundantly for enhanced levels of availability or companies can replace solution components such as a database or sorting package with a different application that better suits their needs.

To support the rapid development and deployment of rehosting implementations, the Clerity MFRRA provides sizing, tuning, and benchmark information, as well as detailed systems management data. This information can be used prior to implementing a project to estimate CPU, memory, I/O, and disk requirements. Companies can also take advantage of Clerity MFRRA suggestions for fine-tuning UniKix TPE and UniKix BPE software as individual implementations progress. Further extending the life of rehosted applications, the Clerity MFRRA shares suggested guidelines for deploying Java technology and Web-based application components in conjunction with rehosting initiatives.

This version of the Clerity MFRRA substantiates an Open Systems platform as a credible alternative to the mainframe for core IBM CICS transactions and batch applications as well as for related third-party infrastructure products. The Clerity MFRRA also demonstrates the exceptional availability, performance, and scalability provided by Clerity and additional third party solutions, critical characteristics for mainframe-based applications.
