Connect to a Server

From ONE Desktop, you can create server connections to enable the usage of certain steps and workflow tasks (SOAP Call, SOAP Multi Call, Jms Writer, Issue Reader/Writer, SCP/SFTP Download/Upload).

The Amazon S3 server connection enables encryption of the data sent to or stored on the server.

Register a new server

To create a new server connection:

  1. In the File Explorer, right-click Servers and select New Server.

  2. Select the Environment. For more information, see Environments.

  3. Specify the server Name and select Implementation.

  4. Configure the server connection based on your server implementation and select Finish.

Once the new server is registered, it shows up in the File Explorer tree.

Server connection added
While in development, right-clicking the server connection and selecting Connect should not be considered a valid connectivity test, and doing so is not necessary to enable step communication.

Amazon S3

Connect to the Amazon S3 server to upload or download files stored there. Once the server connection is registered, you can use it as follows:

  • In workflows to operate on files.

  • In plans as an input or output in the Reader and Writer steps.

In plans and workflows, the server connection can be called using the resource://<resourceName>/<path>/<inputFile> syntax. The steps supporting resources are Text File Reader and Writer, Excel File Reader and Writer, Xml, Json, Avro, Parquet Reader and Writer steps, Complex Xml Writer, Dbf File Reader, and Generic Data Reader.
The drag and drop functionality is supported for files and objects on Amazon S3, Azure Data Lake Storage Gen 1, and Google Cloud Storage servers
Amazon S3 implementation

Amazon S3 does not operate with a folder structure the way other systems do; it operates only with files. It is allowed to have a file with backslash (/) characters in its filename and is represented by the browser as a folder.

When you create a folder on Amazon S3, you create a file with a backslash in its filename. The resulting file and filename cause issues with operations such as Delete or Move in the one-runtime-server:operate-on-file.adoc workflow task when removing the last file from the folder.

Therefore, we strongly recommend using the operation Mkdir in all of your workflow tasks whenever it is necessary. When using the Mkdir operation, your folder will be still available even after its last file is deleted.

Property Description

Select the AWS option.

URL

Specifies the server URL in the s3a://<bucket>[/<directory>] format.

If your S3 buckets are located in the us-east-1 region, specify the region code in your connection string using one of the following formats:

Enables client-side data encryption.

Client key

Fill in a key to encrypt the data on the client side. The field is available when client encryption is selected.

Make the server connection available in the command line and online mode

When executing plans and workflows in the command line (runcif utility) or online mode (from the ONE Runtime Server Admin), it is necessary to make the server connection available to the runtime from the Runtime Configuration file. To learn how to export runtime configuration, see Export and Import Runtime Configuration.

When exported to the runtime configuration file, the server definition part looks as follows:

Server connection in runtime configuration
<?xml version='1.0' encoding='utf-8'?>
<runtimeconfig>
...
 <contributedConfigs>
  <config className=.ataccama.dqc.processor.support.>
   <urls>
    <url
        name="SomeConfiguredServer"
        user="myusername"
        password="crypted:DESede:p63913D4fMa175vrXECs1nOHdV1SG5sUto5HhuV6Izg="
        url="localhost:22"
        />
   </urls>
  </config>
  ...
 </contributedConfigs>
