    Key Outcomes

    Customers can expect improved operational efficiency and reliability of the MID Server due to smart job assignment and advanced logging capabilities. The ITOM Infra Services Workspace provides a unified view of MID Server activities, aiding in swift issue resolution. The new AI-driven MID Guardian Agent helps proactively manage and troubleshoot MID Server operations, contributing to reduced support tickets and downtime.

    Important Upgrade Information

    For upgrading to Zurich, ensure a minimum JRE version of 17.0.10 is used. Access to the download site at install.service-now.com is required for auto-upgrades. Be aware that only one Windows MID Server service is permitted per executable path to avoid startup issues.

    The ServiceNow® MID Server application enables communication and data transfers between a ServiceNow instance and external applications, data sources, and services. MID Server was enhanced and updated in the Zurich release.

    MID Server highlights for the Zurich release

    • MID Server smart workload manager continuously evaluates load and assigns jobs in a cluster to ensure that no server is overloaded.
    • MID Server logging has been improved with log backups that are preserved in a compressed format on a local host with an option to fetch to the instance.

    See MID Server for more information.

    Important information for upgrading MID Server to Zurich

    For the latest MID Server system requirements, see MID Server system requirements. The minimum JRE version supported is 17.0.10 and the recommended version is 17.0.12.

    If you have installed your own JRE, the upgrade process takes the following actions to verify that the MID Server uses a supported JRE:
    • If a MID Server is using an unsupported version of the JRE when it upgrades, the upgrade process displays a warning message with the minimum and recommended JRE version.
    • If a supported JRE is running on the MID Server host, the upgraded MID Server uses that version.

    All MID Server host machines require access to the download site at install.service-now.com to enable auto-upgrades. For additional details, read how the system manages MID Server upgrades.

    Only one Windows MID Server service is permitted according to the executable path. Upgraded Windows MID Servers that have multiple services pointing to the same installation folder can’t start. See MID Server fails to start for more information.

    New in the Zurich release

    ITOM Infra Services Workspace
    The ITOM Infra Services Workspace provides a concise overview of MID Server activity. The dashboard integrates several previously disparate tables so that issues can be monitored and resolved. The workspace provides real-time monitoring, proactive alerts, automation of common tasks, and centralized diagnostics to reduce downtime and support tickets.
    MID Guardian Agent
    The MID Guardian Agent is an advanced AI feature within the MID Server ecosystem/ITOM Infra Services workspace, designed to proactively assist users in diagnosing and resolving issues related to configuration, connectivity, upgrades, and operations. By intelligently analyzing logs, signals, and runtime behaviors, it offers guided troubleshooting steps, automated fixes, and predictive insights. This significantly reduces Mean Time to Repair (MTTR) and enhances the reliability and operational efficiency of the MID server.

    Changed in this release

    Smart Workload Manager in clusters

    MID Servers in a cluster now assign jobs based on the true load, using a variety of criteria. The smart workload manager continuously evaluates the queue size, execution time, CPU usage, and buffer size. The manager then assigns tasks to ensure that no server is overloaded.

    Enhancements to MID Server logging and JFR

    MID Server logging has been improved with log backups that are preserved in a compressed format on local host with option to fetch to the instance. You can enable JFR logs every four hours and backup JFR files for a set time.

    MID Server has improved performance during heavy discovery load

    MID Servers no longer have performance degradation due to script include cache misses when using large amounts of worker threads.

    UI changes

    Coral theme
    Coral is now the default theme for new portal, web, and mobile experiences with Next Experience or Core UI enabled. This theme provides a fresh look and feel, featuring brand-neutral illustrations to enhance your user experience. A dark theme option is available for web and mobile experiences.

    Activation information

    MID Server is a ServiceNow AI Platform feature that is active by default.
