About three months ago I found a script named host_access_control.
The script provides the API to managing several host access and security settings. The script is available on Compute Nodes and Storage Cells since the Exadata Software Version 126.96.36.199.0. The utility is located in /opt/oracle.cellos/host_access_control. The script is not documented in the Exadata Documentation, but in the Super Cluster documentation.
The script called with the Option „-h“ displays the help:Weiterlesen „Change the security settings on Exadata with the script host_access_control“
