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

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.

z/OSMF-Compatible REST API for AI Agents

Expose JES functionality via a standards-based REST interface with native MCP support — enabling AI agents, orchestration platforms, and DevOps toolchains to submit jobs, monitor status, and retrieve output without bespoke integration work.

z/OSMF-Compatible REST API

Stateless per request, gated by the calling user's SAF authority

Every call queries JES directly through SAPI — no daemon, no broker. Access is controlled entirely by the calling user's existing SAF authority. Delivered via Connect/Web.

In addition to its JES Writer capabilities for automated report processing, the Connect/JES component provides a powerful batch program for direct JES report selection and processing. This interface allows administrators and automation scripts to execute JES operations as native z/OS jobs, enabling flexible and efficient control of report handling.

The batch program makes it easy to integrate JES report processing into batch workflows, operational scripts, and existing automation frameworks. Users can select, manage, and process JES output independently of other Connect/MP actions, providing a straightforward way to run targeted report operations when needed.

With this capability, Connect/JES extends the flexibility of Connect/MP by enabling native, scriptable JES processing that fits naturally into z/OS batch environments and enterprise automation strategies.

Transform traditional mainframe output into professional, shareable documents with the built-in PDF Maker feature in Connect/MP. This capability converts JES reports and standard text files into formatted PDF documents, making it easy to distribute, archive, and present critical information outside the mainframe environment.

PDF Maker provides flexible formatting controls and attribute settings, allowing you to customize page layout, fonts, headers, and other presentation and security details to match your reporting requirements. It can be executed as a standalone Connect/MP action or seamlessly integrated as a parameter within other Connect/MP features (eg ZIPJEZ, D21JES), enabling automated PDF generation as part of broader workflow processes.

With PDF Maker, Connect/MP helps modernize mainframe output, turning raw reports into polished PDF documents that are easy to share across teams, systems, and platforms.

The Connect/Hybrid component of Connect/MP includes powerful capabilities for transferring JES reports between different JES subsystems. This feature enables organizations to move spool files and reports across systems reliably, supporting operational needs such as disaster recovery (D/R), backup processing, and workload redistribution.

By allowing JES output to be securely transferred between environments, Connect/Hybrid helps ensure that critical reports remain accessible even when systems change or recovery procedures are activated. This capability simplifies cross-system report management and supports resilient mainframe operations by making it easy to replicate or relocate JES output where it is needed.

With JES Report Transfer, Connect/MP extends its automation capabilities beyond a single system, enabling dependable report mobility across the enterprise mainframe infrastructure.

Many of the world's top mainframe installations are using Connect/MP every day to simplify and accelerate mainframe file exchange, across the Enterprise and beyond.
