Modernizing the mainframe with Artificial Intelligence enhancements: HCL Z Abend Investigator 17.1.0 introduces the following AI capabilities:
- HCL ZAI Abend Intelligence provides real-time host-based AI analysis. It automatically analyzes abends on z/OS using a large language model (LLM) and displays formatted Markdown reports directly in interactive reanalysis. For details, see:
  - The AI analysis report
  - Installing and configuring HCL ZAI Abend Intelligence
- Model Context Protocol (MCP) server: Provides a workstation-hosted Java server on Windows that connects to external AI assistants to z/OSMF REST APIs, enabling assistants to search history files, read SDSF job spools, retrieve fault reports, and extract application source code. For details, see:
The new CompileDateCheck option specifies whether Z Abend Investigator scans user programs in the event list to check if any were compiled within a specified number of days before the abend . If Z Abend Investigator detects recently compiled user programs, the synopsis section of the fault analysis report includes a note. For details, see CompileDateCheck.
Two new commands have been added:
- HTTP command: displays formatted HTTP data located at a specified storage address. See HTTP for the complete command syntax and see Displaying formatted HTTP data (HTTP) for information about how to use this command and interact with the results.
- XML command: displays formatted XML data located at a specified storage address. See XML for the complete command syntax and see Displaying formatted XML (XML) for information about how to use this command and interact with the results.
The LISTHF, LISTHFDUP, and DELETE control statements of the IDIUTIL utility are updated to support the IMS_PGM parameter. You can use this qualifier to filter fault entries based on the IMS program name.
