4.1 Connect to Oracle Data Transforms Instance

This section includes information about connecting to the Data Transforms compute instance by using a Secure Shell (SSH) connection.

Note:

This section is applicable only for Advanced administrative users who would typically connect to the Data Transforms instance to examine the logs for errors. If you are a general Data Transforms developer, you can skip this section.

4.1.1 Connect to Oracle Data Transforms Instance from Linux

You can connect to an Oracle Data Transforms compute instance by using a Secure Shell (SSH) connection. Most Linux distributions include an SSH client by default.

To connect to your Oracle Data Transforms compute instance from Linux,

1. To enable SSH access to Oracle user, log in to your instance using SSH as opc user.

   ssh opc@<IP Address>

   Execute the following commands to copy the authorized keys to Oracle user:

   sudo cp /home/opc/.ssh/authorized_keys /home/oracle/.ssh
   sudo chown oracle:oracle /home/oracle/.ssh/authorized_keys

2. Use the following command to set the file permissions so that only you can read the file:

   $ chmod 400 <private_key>

   where <private_key> is the full path and name of the file that contains the private key associated with the instance you want to access.
3. Use the following SSH command to access the instance.

   $ ssh –i <private_key> <username>@<public-ip-address>

   where
   • <private_key> is the full path and name of the file that contains the private key associated with the instance you want to access.
   • <username> is the default name for the instance. The default user name is oracle.
   • <public-ip-address> is your instance IP address that you retrieved from the Console.

4.1.2 Connect to Oracle Data Transforms Instance from Windows

You can connect to an Oracle Data Transforms compute instance by using a Secure Shell (SSH) connection. For Windows, you can download a free SSH client called PuTTY from http://www.putty.org.

To connect to your Oracle Data Transforms compute instance from Windows,

1. Open putty.exe.
2. In the Category pane, select Window, and then select Translation.
3. In the Remote character set drop-down list, select UTF-8. The default locale setting on Linux-based instances is UTF-8, and this configures PuTTY to use the same locale.
4. In the Category pane, select Session and enter the following:
   1. Host Name (or IP address):<username>@<public-ip-address>, where <username> is the default name for the instance. For Oracle Linux and CentOS images, the default user name is oracle. For the Ubuntu image, the default name is ubuntu and <public-ip-address> is your instance public IP address that you retrieved from the console.
   2. Port: 22
   3. Connection type: SSH
5. In the Category pane, expand Connection, expand SSH, and then click Auth.
6. Click Browse, and then select your private key.
7. Click Open to start the session.

If this is your first time connecting to the compute instance, you might see a message that the server's host key is not cached in the registry. Click Yes to continue the connection.
