Why No Code Changes Matters More Than It Sounds

Many CICS and VSAM applications contain decades of critical business logic. SYSB-II helps improve CICS and batch VSAM file sharing without requiring application source code changes for selected workloads, which avoids the testing risk, cost, delay, and political resistance that come with changing legacy code.

Modernization Without the Rewrite: Keeping Valuable CICS Applications Productive

Not every modernization effort begins with rewriting applications. SYSB-II helps organizations improve availability for valuable CICS and VSAM systems without changing application source code.

Recovery Is the SYSB-II Benefit Too Many Teams Underestimate

Batch abends can disrupt CICS users, delay processing, and create manual recovery work. SYSB-II recovery capabilities help make selected CICS and batch VSAM processing safer and more predictable.

Running Batch During the Day Without Making CICS Users Pay for It

Daytime batch processing can reduce stale data and relieve the nightly critical path, but it must protect CICS users. SYSB-II routes selected batch VSAM access through CICS while online users continue working.

The Hidden Cost of Stale Data in CICS Applications

Stale data in CICS applications delays decisions, slows service, and frustrates users. SYSB-II helps selected batch updates reach VSAM data while CICS remains available.

Why VSAM File Ownership Creates a Modern Availability Problem

CICS-owned VSAM files can create a conflict between online availability and batch processing. SYSB-II helps resolve that conflict by routing selected batch VSAM requests through CICS.

The Batch Window Is Not a Business Strategy

The nightly batch window may feel normal, but it creates downtime, stale data, operational risk, and missed business opportunity. SYSB-II helps mainframe teams keep CICS and VSAM applications available while selected batch jobs run.
