    Warum und wann dieser Vorgang ausgeführt wird

    The em_alert_history and em_impact_status tables can grow to be very large, negatively impacting Event Management performance. Installing the Event Management Performance Accelerator plugin ensures that Event Management performs at a high level. The plugin includes fix scripts that populate missing data, update key fields to maintain data accuracy, and create indexes to enhance performance. These actions help optimize large datasets and reduce the impact on query speed and overall system responsiveness.

    When upgrading from an earlier version with more than 5 million records in either the em_alert_history or em_impact_status tables, you must activate this plugin manually. When there are less than 5 million records, it runs automatically. You can customize this number by modifying the evt_mgmt.plugin_activation.table_max_size property.

    To purchase a subscription, contact your ServiceNow account manager. The account manager can arrange to have the plugin activated on your organization's production and subproduction instances, generally within a few days.

    If you don't have an account manager, decide to delay activation after purchase, or want to evaluate the product on a subproduction instance without charge, follow these steps.
