The listing for the ISO files expands to display the SHA-1 and SHA-256 checksum reference numbers for each ISO file.
Select Download. The Download Manager Installation screen is displayed. The size of the combined ISO files exceeds 11 GB, and takes time to download, depending on the network speed. The estimated download time and speed are displayed in the File Download dialog box.
Select Download the installer, and then select Save File.
Choose a location to save the ISO files. Select Save.

Alternately, you can save each file individually by clicking its name and then specifying a location for the download.

After you have successfully downloaded the Oracle Database Security Central software, you will need to generate the checksum values.

Generating the Checksum Values

After downloading the Oracle Database Security Central software, you need to generate the checksum values.

After the ISO files are downloaded to the specified location, generate a SHA256 checksum for the combined Audit Vault Server ISO file and the Database Firewall ISO file. For example, on a Linux machine run the following command to generate the checksum:
```
$ sha256sum Vpart_number.iso
```
Note: Ensure that the checksum matches the value specified in the Release Notes document that is available along with the installable files. In case of any error or mismatch in the checksum values, download the ISO files again, and validate the checksum values again.

Copying the ISO Image to External Media

Optionally, the Audit Vault Server image or the DBFW ISO image can be copied to another media, like USB. If the files are copied to a Linux based USB medium, perform the following steps:

Run the following command to open the Linux terminal:
```
sudo su -
```
Run the following command to discover the USB device:
```
lsblk
```

Run the following command to erase the data on the USB device:

dd if=/dev/zero of=/dev/<USB device> status=progress conv=fdatasync

Run the following command to copy the iso file directly to the USB device:

dd if=avdf-install.iso of=/dev/<USB device> status=progress conv=fdatasync

Boot the system using the USB device. Ensure the appliance is configured to boot from the USB device.
If the files are copied to a Windows (EFI only - Extensible Firmware Interface) based USB medium, then perform the following steps:
1. Run the following command to open the Windows command prompt and to load the diskpart:
```
diskpart
```
2. Run the following command to discover the USB device:
```
list disk
```
3. Run the following command to select the USB device:
```
select disk 1
```
4. Run the following commands to erase or format the data on the USB device:
```
clean
```
```
create partition primary
```
```
format fs=fat32 label=AVS_2_26_0_0_0
```
  Or
```
format fs=fat32 label=DBFW_2_26_0_0_0
```
  Where X is the specific RU release number in Oracle DBSecCentral.
5. Run the following command to add Master Boot Record (MBR) to the USB device:
```
active
```
6. Run the following command to exit the diskpart:
```
exit
```
