Z Abend Investigator (ZAI) helps you determine the root cause of an application
abend and recover from it quickly
HCL ZAI helps you determine the root cause of an
application abend by analyzing the application’s environment in
real-time or a system dump. ZAI provides detailed analysis of the abend at
source level of your application and assist in efficient recovery.
Supports analysis of application abends happening in z/OS, TSO, Language Environment (LE), CICS, IMS, DB2, MQ Series, UNIX System Services.
Provides source level analysis of application abends written in Enterprise COBOL, Enterprise PL/I, Assembler, C/C++ and Java. ZAI also supports analysis of applications optimized by IBM Automatic Binary Optimizer (ABO).
Synopsis of key information
What happened and why? What program? What line of source code? What source variables were involved?
Designed to work in production systems
Invoked via invocation exits of z/OS, Language Environment and CICS environments at the time of application abend to capture just enough information to assist efficient problem diagnosis process. This means minimal overhead to your production systems.
“Must have” tool for COBOL compiler upgrade projects: no overhead to your production systems when there are no abends and only a minimal overhead during abend analysis as IBM Enterprise COBOL V4.2 compiler End of Support date approaches (September 30, 2021). ZAI speeds up the problem diagnosis process for experienced as well as new developers alike.
