About this task

Attention: Failure to execute the steps of this task in sequential order might result in the loss of the anomaly detection configuration data and anomaly score data stored on the Insight server.

Steps

  1. Back up the existing version of OnCommand Insight to preserve the anomaly detection registrations, application monitoring, anomaly history, and so on.
  2. Shut down the OnCommand Insight server.
    Attention: Failure to shut down the OnCommand Insight server before uninstalling the anomaly detection software results in the loss of the anomaly detection configuration data and anomaly score data stored on the Insight server.
  3. Uninstall the anomaly detection software: sudo /usr/bin/oci-prelert-uninstall.sh
    The system displays a "failure to unregister" message. You can ignore this message.
  4. Install the newer version of OnCommand Insight by using the upgrade process.
    See the OnCommand Insight Installation Guide for instructions.
  5. Restart the OnCommand Insight server.
    The system reports that applications are "failing to monitor". You can ignore these failures.
  6. Navigate to the directory where the installer is located: cd oci-prelert-<version>-linux-x86_64
  7. Install the anomaly detection software: sudo ./oci-prelert-install.sh
    The anomaly detection software is successfully registered with the OnCommand Insight server.
