Output Schema

By default, each stream will be output into its own table in Oracle. Each table will contain 3 columns:

• _AIRBYTE_AB_ID: a uuid assigned by Airbyte to each event that is processed. The column type in Oracle is VARCHAR(64).
• _AIRBYTE_EMITTED_AT: a timestamp representing when the event was pulled from the data source. The column type in Oracle is TIMESTAMP WITH TIME ZONE.
• _AIRBYTE_DATA: a json blob representing with the event data. The column type in Oracles is NCLOB.

Enabling normalization will also create normalized, strongly typed tables.

Getting Started (Airbyte Cloud)

The Oracle connector is currently in Alpha on Airbyte Cloud. Only TLS encrypted connections to your DB can be made from Airbyte Cloud. Other than that, follow the open-source instructions below.

Getting Started (Airbyte Open Source)

Requirements

To use the Oracle destination, you'll need:

• An Oracle server version 18 or above
• It's possible to use Oracle 12+ but you need to configure the table name length to 120 chars.

Network Access

Make sure your Oracle database can be accessed by Airbyte. If your database is within a VPC, you may need to allow access from the IP you're using to expose Airbyte.

Permissions

As Airbyte namespaces allows us to store data into different schemas, we have different scenarios and list of required permissions:

Login user	Destination user	Required permissions	Comment
DBA User	Any user	-
Regular user	Same user as login	Create, drop and write table, create session
Regular user	Any existing user	Create, drop and write ANY table, create session	Grants can be provided on a system level by DBA or by target user directly
Regular user	Not existing user	Create, drop and write ANY table, create user, create session	Grants should be provided on a system level by DBA

We highly recommend creating an Airbyte-specific user for this purpose.

Setup the Oracle destination in Airbyte

You should now have all the requirements needed to configure Oracle as a destination in the UI. You'll need the following information to configure the Oracle destination:

• Host
• Port
• Username
• Password
• Database
• Connection via SSH Tunnel

Airbyte has the ability to connect to a Oracle instance via an SSH Tunnel. The reason you might want to do this because it is not possible (or against security policy) to connect to the database directly (e.g. it does not have a public IP address).

When using an SSH tunnel, you are configuring Airbyte to connect to an intermediate server (a.k.a. a bastion sever) that does have direct access to the database. Airbyte connects to the bastion and then asks the bastion to connect directly to the server.

Using this feature requires additional configuration, when creating the source. We will talk through what each piece of configuration means.

1. Configure all fields for the source as you normally would, except SSH Tunnel Method.
2. SSH Tunnel Method defaults to No Tunnel (meaning a direct connection). If you want to use an SSH Tunnel choose SSH Key Authentication or Password Authentication.
   1. Choose Key Authentication if you will be using an RSA private key as your secret for establishing the SSH Tunnel (see below for more information on generating this key).
   2. Choose Password Authentication if you will be using a password as your secret for establishing the SSH Tunnel.
3. SSH Tunnel Jump Server Host refers to the intermediate (bastion) server that Airbyte will connect to. This should be a hostname or an IP Address.
4. SSH Connection Port is the port on the bastion server with which to make the SSH connection. The default port for SSH connections is 22, so unless you have explicitly changed something, go with the default.
5. SSH Login Username is the username that Airbyte should use when connection to the bastion server. This is NOT the Oracle username.
6. If you are using Password Authentication, then SSH Login Username should be set to the password of the User from the previous step. If you are using SSH Key Authentication leave this blank. Again, this is not the Oracle password, but the password for the OS-user that Airbyte is using to perform commands on the bastion.
7. If you are using SSH Key Authentication, then SSH Private Key should be set to the RSA Private Key that you are using to create the SSH connection. This should be the full contents of the key file starting with -----BEGIN RSA PRIVATE KEY----- and ending with -----END RSA PRIVATE KEY-----.

Encryption Options

Airbyte has the ability to connect to the Oracle source with 3 network connectivity options:

1. Unencrypted the connection will be made using the TCP protocol. In this case, all data over the network will be transmitted in unencrypted form.
2. Native network encryption gives you the ability to encrypt database connections, without the configuration overhead of TCP / IP and SSL / TLS and without the need to open and listen on different ports. In this case, the SQLNET.ENCRYPTION_CLIENT option will always be set as REQUIRED by default: The client or server will only accept encrypted traffic, but the user has the opportunity to choose an Encryption algorithm according to the security policies he needs.
3. TLS Encrypted (verify certificate) - if this option is selected, data transfer will be transfered using the TLS protocol, taking into account the handshake procedure and certificate verification. To use this option, insert the content of the certificate issued by the server into the SSL PEM file field
