Included with every Connect/MP component: MCP API access for JES, FILE, and 3270 — for your own scripts and agents — plus the chat-only Web Workspace. Connect/AI unlocks agentic execution: workspace tool use and native batch inference invoked from JCL.

Turn Mainframe JES Output into Real-Time Automation, Integration, and AI-Driven Actions.

Extend JES to Modern Workflows

When qualifying JES output is detected, the corresponding Connect/JES task automatically triggers the associated Connect/MP action — enabling automated processing, transformation, and delivery of JES output without modifying existing batch jobs.

This architecture allows organizations to extend traditional JES processing into modern automation workflows while preserving existing investments in z/OS batch.

Downstream Automation Workflows

The output of the Connect/JES-initiated Connect/MP component can take several forms — producing a z/OS or USS file, FTP’d or emailed, or piped into a distributed application or subsequent Connect/MP component process, all under the control of a single z/OS job.

High-Performance, AI-Ready Access Powered by Connect/Web New

Connect/JES delivers JES access without the JVM overhead of z/OSMF — purpose-built for low-latency agentic pipelines — enabling Connect/AI, orchestration platforms, and DevOps toolchains to submit jobs, monitor status, and retrieve output without bespoke integration work — writes remain gated by your own approval controls.

Features

ACTION Integration

Invoke ZIP, MAIL, PDF, AI — any Connect/MP action

Can invoke any Connect/MP ACTION from JES output, including ZIP, MAIL, PDF, and AI, enabling automated pipelines triggered directly by JES spool activity.

Continuous or One-Time Processing

One-time run or persistent monitoring mode

Can be run as a one-time process or remain awake to process selected reports as they are created — continuing until stopped or z/OS is shutdown.

Flexible Selection Criteria

Select by JOBNAME, JOBID, CLASS, FORM, DESTINATION

Flexible selection criteria let you target specific JES output using JOBNAME, JOBID, CLASS, FORM, and DESTINATION — ensuring only the right reports are processed.

Disposition Control

KEEP or DELETE spool output after processing

DISPOSITION control determines whether spool output is retained (KEEP) or removed (DELETE) after processing, giving you full control over JES resource management.

Flexible Output Methods

Route to Sequential, PDS, ZFS, EMAIL, FTP, PIPE

Route processed JES output to multiple destinations: Sequential datasets, PDS, ZFS, EMAIL, FTP, or piped into file transfer and CLI commands — enabling seamless integration with any downstream system.

Native-Speed JES Access — No JVM Overhead

Every request reflects live JES status, gated by the calling user's SAF authority

Every request queries JES directly, in real time — nothing cached, nothing stale. Access is controlled entirely by the calling user's existing SAF authority. Delivered via Connect/Web.

Related Functionality

JES Reports to PDF

Convert JES output and text files into formatted, shareable PDF documents

Transform traditional mainframe output into professional PDF documents for easy distribution, archiving, and presentation outside the mainframe environment.

Flexible Formatting Controls

Customize page layout, fonts, headers, and security settings

PDF Maker provides attribute settings for page layout, fonts, headers, and security details — full control over how reports are presented to match your specific reporting requirements.

Standalone or Integrated

Run independently or as part of ZIPJEZ and D21JES workflows

Execute as a standalone Connect/MP action or seamlessly as a parameter within other processes — including ZIPJEZ and D21JES — enabling automated PDF generation as part of broader workflow pipelines.

Cross-System Spool Transfer

Move JES reports between JES subsystems for DR, backup, and workload redistribution

The Connect/Hybrid component enables reliable transfer of spool files and reports across different JES subsystems — supporting disaster recovery, backup processing, and workload redistribution across your mainframe infrastructure.

Resilient Report Access

Critical reports stay accessible during recovery procedures and system changes

JES output can be securely transferred between environments, ensuring critical reports remain accessible even when systems change or recovery procedures are activated — simplifying cross-system report management.

Enterprise Report Mobility

Dependable report mobility across the enterprise mainframe infrastructure

Connect/MP extends automation beyond a single system — enabling dependable report mobility that supports resilient mainframe operations by replicating or relocating JES output wherever it is needed.
