Topaz for Program Analysis: Mainframe Program Analysis with Runtime Visualizer

Topaz for Program Analysis intelligently analyzes mainframe programs and presents the results of that mainframe program analysis in a visually intuitive manner. Using program structure and logic flow charts, Program Analysis reduces learning curves for programmers doing mainframe application development who are unfamiliar with the mainframe or unfamiliar with the structure of a program. The mainframe program analysis provides invaluable insights into programs that don’t have documentation and are 20, 30 or even 40 years old.

Topaz for Program Analysis now includes Runtime Visualizer, a new feature that provides unprecedented graphical visibility into often-complex interactions between mainframe programs. This visibility makes it easy for veteran and novice developers alike to quickly understand, update and troubleshoot even the oldest and most complex mainframe code.

With Runtime Visualizer, developers can:

  • Get a clear and accurate “snapshot” of a program’s real behavior in either production or test environments under runtime conditions.
  • Generate a dynamic intuitive map of the external calls a program executes during any specified runtime within minutes—without any source code dependency. This capability saves hours or days of painstaking work, while ensuring accurate/complete results.
  • Understand a program’s external calls to see how often programs call each other during a runtime and/or the specific datasets a program accesses at each point in its execution to better pinpoint potential performance bottlenecks, inefficiencies and inter-program impacts.
  • Drill down to specific compile and Load Library information for programs.

In addition, Topaz for Program Analysis now features Online Projects and Impact Analysis. Mainframe application developers of all skill levels can more quickly and accurately perform mainframe program analysis of code change impacts by creating Java-like “projects”—logical collections of data sources—that allow them to discover and investigate dependencies across programs and copybooks, without having to move code off the mainframe.

Mainframes have long been the platform of choice for enterprise systems of record, and today they are the backbone for many modern digital applications. Compuware’s commitment to supporting current as well as the next generation of mainframe professionals with easy to use, innovative tools is of great service to enterprise customers who recognize the mainframe as the modern, digital platform it will continue to be for years to come.

Understand Complex and Unfamiliar Programs Faster with Mainframe Program Analysis

Now developers don’t have to sift through comments, read outdated documentation or rely on mainframe application development experts to understand COBOL and PL/I application logic and logical dependencies. Program Analysis provides an instant static visual summary of what a developer needs to know about a program, enabling them to:

  • Identify problems such as undefined fields, range violations and dead code to correct problems before compiling.
  • Easily gauge program attributes such as size, complexity, number of files and tables to quickly determine the scope of work.
  • Easily assess procedure level metrics such as number of performs, I/O, conditionals, GOTO statements and McCabe complexity metrics to easily pinpoint where codechanges need to be made.
  • Generate a rich mainframe data visualization of the flow of data within programs. Data Flow shows the complete usage for any given field: how data gets into that field; how that field is used to set other fields; and how that field is used in comparisons—all displayed at-a-glance.

Make Code Changes in Mainframe Application Development with More Confidence

With access to automated, fast, consistent and current information about a program—and now the ability to see how programs interact with each other during a live runtime of a specific event—even the most inexperienced mainframe application developers can make code changes to programs more confidently.

Instantly See Code Change Results

Build new charts after a code fix to confirm the logic flow changed in the way it was intended and see if any new code problems were inadvertently introduced.

Improve Code Reviews

Developers have a visual summary of the code changes, which both improves code reviews and serves as documentation for other developers who may have to make code changes to the program.

IBM z Systems support the core systems of record for many of today’s enterprises. Leveraging those investments to improve customer engagement and enhance employee effectiveness is critical for such organizations as they compete in a mobile-first digital world. The new release of Topaz demonstrates that Compuware is fully committed to and fully capable of helping organizations meet this critical challenge by mainframe-enabling a new generation of developers and QA engineers.

Topaz for Enterprise Data: Improve Enterprise Data Management

Topaz for Enterprise Data enables mainframe developers and mainframe data architects to discover, conduct mainframe data visualization and work with both mainframe and non-mainframe data in a common, intuitive manner. Using Topaz for mainframe application development, next-gen developers as well as seasoned IT pros can handle enterprise data management and manipulate applications with greater agility, speed and confidence to better meet the demands of mobile and analytics.

Edit Data with a Single Enterprise Data Editor

Source-specific tools, such as a data browser and mainframe data editor, are no longer needed for mainframe application development. Topaz’s Enterprise Data Editor features a single intuitive user interface for enterprise data management of Oracle, SQL Server, IMS, DB2 and other data types across the enterprise.

Mainframe Data Visualization

Many times developers struggle to understand the complex relationships among their enterprise data. Mainframe data visualization using Topaz’s Relationship Visualizer provides a graphical representation of data relationships across the enterprise, enabling the management of vast quantities of data objects . This feature is especially useful when extracting data for testing purposes.

Quickly Copy Files and Data with a Simple Drag and Drop

Topaz for Enterprise Data Host to Host Copy will copy files such as VSAM, JCL, flat files, source code and load libraries from one LPAR to another with a simple drag and drop or right click. The data is compressed and the processing is zIIP enabled for optimal performance.

Enterprises can gain tremendous business value from mainframe-resident data, but making use of this key asset is often limited by the need to understand the mysteries of applications developed in CICS and COBOL. Compuware is taking aim at this limitation by more broadly empowering IT professionals to understand and leverage data residing on IBM System z using graphical visualization tools.
