ICE - IMAGE Control Environment

ICE - IMAGE Control Environment detects changes, points of failure, and risks to the integrity of the z/OS systems. ICE help systems staff to examine the system and document for management, security and audit teams, that their job is being done correctly, has been verified and does not have further unintentional adverse impact outside of where the change was made. So no change management request is closed prior to proof of valid liveand target systems.

A background monitor activates a virtual IPL for each image (and its alternate images) using the zOS-Inspector, Sysplex-Inspector, and primarysub-system inspectors (e.g. JES, VTAM, TCPIP) maintaining in-depth change-management and documentation of your images. Additionally for DR purposes ICE runs as a started task directly under z/OS and automatically creates and maintains full screen access, ISPF/PDF, to its own z/OS sub-system when VTAM, JES or TSO are unavailable giving various system management and recovery functions.
