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 AI agents, orchestration platforms, and DevOps toolchains to submit jobs, monitor status, and retrieve output without bespoke integration work.
