Dynamic software analysis for AIX-based application development

IBM Rational® PurifyPlus™ for IBM AIX® is a dynamic software analysis tool for AIX-based application development. This solution helps you develop XL C/C++ programs on the AIX platform. Rational PurifyPlus for AIX provides run-time analysis to help improve your application reliability and performance.

Advanced memory debugging: Locates the cause of memory corruption errors and provides detailed information, such as the error location (function call stack) and the size of the affected memory.
Memory leak protection: Improves memory utilization and speeds debugging time.
Application performance profiling: Highlights application performance bottlenecks and improves application understanding with a graphical representation of function calls.
Code coverage analysis: Identifies untested code with line-level precision.
Binary instrumentation technology: Allows integration with third-party libraries and does not require access to source code.

Advanced memory debugging

Rational PurifyPlus analyzes memory accesses and manipulations by your program and identifies memory errors before they occur.
This software locates difficult to find memory errors, such as uninitialized memory access, buffer overflow, and improper freeing of memory.
Rational PurifyPlus offers APIs that you can invoke from your program or debugger to help you debug memory problems.

Memory leak protection

Rational PurifyPlus for AIX scans all memory and reports all memory blocks without any pointers as memory leaks (MLK).
This software reports all blocks as potential leaks (PLK) when there are no pointers to the beginning of the block, but there are pointers to the middle of the block.
It specifies the line where the leaked memory was allocated.
Rational PurifyPlus lets you debug at the memory allocation site where the leak is reported, and then track what you are doing with that pointer and where you are overwriting it.

Application performance profiling

Rational PurifyPlus for AIX improves application performance by highlighting bottlenecks and changes that slow down new builds.
This solution helps you determine what is happening internally in the source code when test automation slows down with a new build, including changes in source code, test code, test data or environment, and connectivity.
Rational PurifyPlus identifies where time is spent in an application and the most important code to optimize.

Code coverage analysis

Rational PurifyPlus for AIX measures how much of the product code was exercised in a test suite and how much remains to be tested.
This software helps determine if there are any redundant test cases: tests that cause unnecessary delays by exercising the same path in the code over and over again.

Binary instrumentation technology

Rational PurifyPlus instruments code at the object level.
You do not need to recompile code to analyze it.
Rational PurifyPlus analyzes third-party libraries, even if you do not have the source code.
