HCL's statements regarding potential future products are subject to change without notice. Fault Analyzer for z/OS is a tool that helps determine the cause of application abends by delivering information about what happened, the program involved, relevant source code lines, and source variables. It supports various environments like z/OS, CICS, IMS, and DB2. Fault Analyzer can analyze abends in real-time, interactively with additional information, or in batch mode.

- 3. an IBM + HCL product What is Fault Analyzer for z/OS? âą FA can capture abends in the following environments: âą z/OS âą LE (Language Environment) âą CICS âą IMS âą DB2 âą MQ Series âą UNIX System Services âą Supports source display of the following languages: âą COBOL, PL/I, Assembler, C/C++ and Java. âą Fault Analyzer (FA) is a tool that helps you determine the cause of an application abend âą Enabling you to more quickly identify and resolve the problem âą Delivers information about an application when it has abended, to help you assess: âą What happened, and why? âą What program? âą What line of source code? âą What source variables were involved?
- 4. an IBM + HCL product The key value proposition based on a simple example Problem analysis steps with FA:Problem analysis steps without FA: 1. Capture CEEDUMP or MVS dump 2. Determine abend offset into program from dump 3. Obtain a matching compiler listing â need to make sure it really matches! 4. Using the listing, identify the matching source line for the abend offset 5. Identify data fields involved and their offsets into working storage 6. Validate the content of each data field in the dump to determine the one(s) in error 7. Fix the problem

- 6. an IBM + HCL product How to use Fault Analyzer for z/OS? Different modes of operation âą Real-time analysis âą Captures abends in real-time and performs analysis. âą Produces a real-time analysis report. âą Optimized for usage in production systems with no overhead when no abend. âą Creates a fault entry which can be analyzed in detail later with additional information (eg. Source mapping information). âą Interactive reanalysis âą Possibly gather additional information by supplying additional information (eg. Compiler listing for source display). âą View storage areas not in the real-time report. âą Perform analysis of SYSMDUMP data set or analysis of CICS system dump. âą Batch reanalysis âą Re-generate real-time report with additional information (eg. Source mapping information). Optionally overwrite the existing real-time report. Different user interfaces ïŽ ISPF ïŽ CICS ïŽ Eclipse ïŽ Browser
- 7. an IBM + HCL product Problem determination of 64-bit programs âą Enhanced to provide abend analysis of programs running in AMODE 64. âą Side file processing is enhanced to support Enterprise PL/I programs compiled with LP64 compile option. âą The problem analysis report remains consistent for 64-bit programs to ensure all users are able to take advantage of the enhancement immediately when abends occur in your new 64-bit programs. âą The product infrastructure is enhanced to ensure that existing features of Fault Entry space management are not affected by large Fault Entries generated as a result of large application storage areas residing in 64-bit storage. âą Fault Analyzer is also enhanced to support analysis of abending High-Level Assembler programs running in AMODE 64 and Java program errors, exceptions and abends occurring in 64-bit Java Virtual Machine. 7
- 8. an IBM + HCL product Exploitation of z/OS compiler technology No more missing compiler side files during problem analysis 8 Only product to provide support for Automatic Binary Optimizer for z/OS âą Automatic Binary Optimizer for z/OS (ABO) optimizes COBOL binary programs to the target hardware platform without re-compiling the source files. âą Fault Analyzer provides an utility to transform the original compiler listing with the output from ABO to ensure Fault Analyzer can report abend analysis of optimized programs using the source display of the original abending program. Reporting compiler information for the abending program âą As part of event summary information Fault Analyzer provides, compiler and its options used to create the program is reported. âą This information is useful to ensure optimal programs are produced for your target systemâs hardware level.

- 11. an IBM + HCL product Success story: HSBC Bank Argentina âą We've increased programmer productivity by 10 percent and cut development costs. Not only that, but we've experienced significant decreases in the number of transaction failures within our applications.â, âą Developers can also quickly access reports within Fault Analyzer for z/OS software to identify exactly which instructions within an application are causing problems in the production environment. âBefore, when there was a failure in production, determining the root-cause issue was not a simple process,â says Mr. De Hoz. We had to have technical support people analyze the issue before providing any help to our development team. With Fault Analyzer reports, the developers themselves can easily identify problems. That saves time and money.â
