  • Supported internet browsers (used for accessing Z Understand Configuration Service Admin):
    • Google Chrome (recommended)
    • Mozilla Firefox
    • Microsoft Edge
  • Download the OrientDB docker image. Since an air-gapped system cannot directly download the necessary docker image, you need to manually download and transfer the image. To install Z Understand on an air-gapped system, complete the following steps before your installation:
    1. On a Linux system with internet access, run the following command: 
      podman save orientdb:3.2.53 > orientdb.tar
      Starting with May 2024 release, OrientDB version 3.2.53 or later is required for Z Understand.
    2. Transfer the orientdb.tar to the air-gapped system where you want to install Z Understand.
    3. Run the following command: 
      podman load -i orientdb.tar
    4. Proceed with the normal installation process for Z Understand.
