BMC Compuware Xpediter vs IBM Application Performance Analyzer for zOS comparison

Xpediter is Compuware’s mainframe application interactive debugging tool. It also offers code coverage for mainframe application analysis.

Xpediter enables developers to get into an interactive test session with minimal effort and quickly move applications into production with greater confidence.

With Xpediter, developers can:

• See and control source code execution line by line
• Fully understand what each individual instruction is doing
• See and control all data variables within a test session
• Resolve production abends without impacting program logic or risking data corruption
• Monitor and control execution with added flexibility
• Use Code Coverage to view documented proof that code has been executed
• Trap transactions initiated by a remote source or a non-terminal task
• Gain full control of testing
• Create conditions during test to ensure execution of all code in a program
• Work alongside other developers who are debugging application code in the same or different logical IMS systems through Xpediter’s integration with COPE IMS virtualization technology

IBM Application Performance Analyzer for z/OS measures and reports how applications use available resources. This easy to use tool helps you identify system constraints and improve application performance.

Application Performance Analyzer for z/OS:

• Helps you maximize the performance of your existing applications and improve response time of online transactions and batch turnaround times.
• Gives you the information needed to isolate performance problems in applications and test the effect of increased workloads on your systems.
• Monitors, analyzes and reports the performance of CICS, Assembler, COBOL, PL/I, C/C++, DB2, IMS WebSphere MQ and WebSphere Application Server applications.
• Collects samples from the monitored address space and analyzes the system or resource application usage of CPU, DASD, I/O or the total address space.
• Features online analysis reports that can be created as PDF or XML files, so that you can view them on workstations or transfer them easily to other applications.
