Analytical Ecosystem
If the Unity system is undergoing planned maintenance, wait until the maintenance window is complete before checking managed system health.
  1. At unityadmin, run the following command:
    STATUS;
    The expected status for each system is running.
  2. If the status is not running, do one of the following:
    Status Action
    Out of Service or Read-Only
    1. Confirm the system is not undergoing maintenance.
    2. If you need the system to process queries, contact an administrator, then run the following command from unityadmin if advised:
      SYSTEM RECOVER;
    Unrecoverable
    1. Do one of the following:
      • If the system was previously active, contact an administrator to confirm it was not deactivated.
      • If the system is a new system or unrecoverable because of user action, sync and activate the system.
      • If the system was not previously active and is not a new system, open an incident.
    Interrupted (not previously interrupted)
    1. Check alerts for root cause of the system interrupt.
    2. If the root cause is not apparent and does not resolve on its own, open an incident.
    Disconnected
    1. If there is no planned outage in progress, check connectivity between Unity and the disconnected system. See Responding to Critical Events.
      A system may become disconnected for any of the following reasons:
      • Database for the managed system is not running.
      • Unity Management User is unable to log in.
      • Unity is unable to reach the managed system over the network.
      • Management system is not responding to status request from Unity because the system is busy or the database is unavailable.
