FTP Adapter Capabilities

The FTP Adapter enables the integration of servers supporting File Transfer Protocol (FTP) and Secure Shell (SSH) File Transfer Protocol (sFTP) into Oracle Integration. The connectivity agent must be used for the latter environment.

The FTP Adapter has the following capabilities:

  • Transfers (reads and writes) files to any publicly accessible server in either binary or ASCII format. The FTP Adapter can connect to FTP and sFTP servers that are publicly available on the internet.

  • Supports using the connectivity agent to read and write files from an FTP server that is not publicly accessible. Encryption and decryption of these files is supported with the connectivity agent. The FTP server may be behind a firewall, but is accessible from the connectivity agent host. See Configure the Endpoint Access Type and Invoke Operations Page.
  • Supports connecting to private resources that are in your virtual cloud network (VCN) with a private endpoint. See Connect to Private Resources in Provisioning and Administering Oracle Integration 3 and Configure the Endpoint Access Type. This type of connection does not use the connectivity agent.
  • Supports dynamically updating the invoke connection to use at runtime. This feature enables you to reuse the same integration to send requests to multiple end systems or instances of the same application without creating separate integrations for each. See Dynamically Update Invoke Connections at Runtime.

  • Supports streaming for transferring large files.

  • Enables the integration developer to build an integration for polling (retrieving files) from remote FTP and sFTP servers and for uploading the files onto remote FTP/sFTP servers. Oracle Integration provides the capability for scheduling the time and frequency at which to run these integrations.

    See Define the Integration Schedule in Using Integrations in Oracle Integration 3.

  • Enables you to specify the path of the source directory and schema of the files to consider while polling. You can also specify the directory that does not take part in polling. Once the schema matches with that of the file in the input directory, the file can either be moved/archived to a specific location or deleted. Files that do not support the chosen schema are transferred to the rejection directory.
  • Supports the optional describing of the schema (data definitions) for the files uploaded/downloaded to and from FTP servers using one of the following formats.
    • Sample delimited document (for example, .CSV).

      Note:

      Supported delimiters in the file are single space, comma, semicolons, pipe, or tab.
    • XML schema (XSD) document
    • Sample XML document (Single or No NameSpace)
    • Sample JSON document

  • Enables you to encrypt a file that is being uploaded to remote FTP/sFTP servers using Pretty Good Privacy (PGP) cryptography. Encryption and signing of the file while uploading to remote FTP/s(FTP) servers are currently available only when the servers are publicly accessible. For privately hosted FTP/(s)FTP servers, you must encrypt and/or sign the file prior to uploading the file to the privately-hosted server using the Using Integrations in Oracle Integration 3.

  • Enables you to decrypt a file being read or downloaded from a remote FTP/sFTP server using PGP cryptography. Decryption and verification of the file while downloading from a remote FTP/s(FTP) server to Oracle Integration are currently available only when the servers are publicly accessible. For privately hosted FTP/(s)FTP servers, you must download the file from privately-hosted FTP/(s)FTP servers to Oracle Integration using the FTP Adapter prior to decrypting and verifying the contents of the file.

  • Supports implicit and explicit FTP over SSL.

  • Supports FTP, sFTP, and FTP over SSL connections. For FTP over SSL connections, you must use an SSL certificate in Public-Key Cryptography Standard (PKCS12) format. For sFTP connections using a key, you must use a key in PEM format.

    See Using Secure FTP with the Oracle FTP Adapter.

  • Supports self-diagnosing connectivity issues that may occur when integrating with external sFTP servers.

  • Supports host key authentication, public key authentication, and multilevel authentication:

    • Supports different authentication schemes
    • Supports different types of file handling operations (List File, Read File, Write File, Download File, Move File, and Delete File)
    • Supports compression and decompression of files in ZIP and GZIP formats
  • Supports signing the content before sending the file to an FTP server. You can upload the PGP sign private key and PGP sign private key password on the Connections page. Signing can be combined with PGP encryption.
  • Supports verification of the signature after downloading the file from the FTP server. You must upload the PGP sign public key on the Connections page to verify the signature.

  • Supports using File Server with the FTP Adapter to read and write files. File Server is an sFTP server and uses sFTP connection details. You can also use a File server action to connect to File Server.

You can configure the FTP Adapter as an invoke connection in an integration in Oracle Integration. The FTP Adapter is one of many predefined adapters included with Oracle Integration. See the Adapters page in the Oracle Help Center.
