# Before you start

> Outlines environment prerequisites and compatibility requirements for Oracle TDE integration.

Verify your environment meets these requirements.

## Supported hardware

* KMES Series 3, application version `6.3.1.x` or later, with initial setup completed (including loading a Platform Master Key and network configuration).

## Supported operating systems

* Linux (Rocky Linux 8 for this example – GUI not required): [**https://rockylinux.org/download/**](https://rockylinux.org/download/)
* Windows 10 or later

## Required access

* An account on the KMES with administrator permissions to create roles, identities, TLS PKI, and update system settings.
* Local administrator/root access on the machine where Oracle DB is installed.

## Network and firewall

* Allow outbound TCP port**2001** (default Host API port) from the machine running Oracle Database to the KMES Series 3, specified by FQDN (for example, `kmes.example.com`) or CIDR (for example, `10.0.0.0/24`).

<Warning>
  TLS inspection or SSL proxies can break mutual TLS handshakes. Exempt the KMES FQDN(s) from inspection. Configure the KMES Series 3 with an FQDN so the exemption applies.
</Warning>

* Oracle Database 19c

<Note>
  This guide assumes that you run the server, have root permissions, and have already installed the Oracle database with the necessary configurations to support TDE.
