The new version of IBM Application Performance Analyzer V14.1 brings exciting enhancements that will help you improve the performance of your applications by providing an extensive set of new and enhanced functionality that measures and reports how applications use available resources. APA V14.1 is bundled with IBM Application Delivery Foundation for z Systems V3.1.


APA V14.1 continues with the Day 1 support commitment and this new version includes support for the new z14 hardware, the z/OS V2.3 operating system, new compilers (Enterprise COBOL for  z/OS  V6.2, Enterprise PL/I for  z/OS  V5.2,  z/OS  V2.3 XL C/C++), Automatic Binary Optimizer for z/OS V1.3 and the updated subsystem (CICS® TS for z/OS  V5.4). In addition it maintains the support for other subsystems and environments including ADABAS 8.3.3, NATURAL 8.2.6, WAS 9.0, Java 8, IBM MQ for z/OS 9.0, and IMS V14.1 and DB2 V12.1.


New features in APA V14.1 include:


  • IMS MASS Java support
  • New sampling notification exit
  • New report to aggregate IMS MASS requests
  • Adabas and Natural support in IMS
  • MQI support of RRS in IBM MQ V8 and V9
  • PL/I V5 64-bit source program mapping
  • Infrastructure changes in preparation for 64-bit support
  • XCF diagnostic message enhancements
  • Dataset security enhancements for ESD extraction
  • DB2 extractor performance enhancements
  • File sampling performance enhancements


Enhancements specific to the plug-in include:


  • Support for Eclipse Neon V4.6.3 as part of the IBM Explorer for z/OS Aqua release train
  • Refresh STC View when connecting from another perspective
  • Support for OS X


APA is also included in the Host Configuration Assistant, which helps you to simplify planning and configuration of ADFz z/OS components.


If you are not familiar with APA, please check out the newest videos that show both the Eclipse and 3270 user interfaces. APA has some unique capabilities that deliver extremely accurate and efficient information to help with analysis:


  • Samples are non-intrusive with small footprint, because they are taken in SRB mode (not TCB mode). No I/O is performed in the target address space.
  • You can measure small snapshots, with observation granularity to one second
  • You can capture multiple data activities for enhanced accuracy, such as
    • type 1 and 6 SVC activities
    • activities that hold the local lock
    • activities that runs in SRB mode


Look to IBM APA for continued day 1 support, flexibility, ease of use and improvements to help you identify z/OS application performance and response time problems, and assist in reducing resource consumption.
