21CS has been consistently investing in the future of the VSE ecosystem since completing our 2021 source code license agreement with IBM. We’ve recruited a new wave of developers who work alongside VSE experts to improve the operating system for years to come. Our first version of the operating system, VSEn, offers key feature updates and non-disruptive compatibility with previous versions of IBM z/VSE 5.2, 6.1 and 6.2.

Begin your journey to the cloud IBM Z Batch Resiliency (IZBR) provides real-time resiliency for non-database managed data with automatic recovery processes, leveraging detailed analytic reporting that can reduce reliance on complex domain-specific and possibly error-prone manual approaches. IZBR reduces mean time to recovery from hours or days by identifying at-risk data at the point of failure within minutes, enabling rapid restoration of data sets and determining possible downstream impacts associated from the point of corruption forward.
