Overview

Who performs this task

Typically there are only a few Shared Service Administrators supporting a team. This person is responsible for Shared Service running within the cloud. They need to have Workload resources administration with full permissions or the Cloud Administrator role.

Procedure

Preparing the SSH key pair on Windows

If you are on a Windows box, you can generate the key pair using PUTTYGEN.EXE

Click generate button, the tool will generate the key pair for you. (move your mouse to provide some randomness for the tool)

Key generated. You can save the key pair in files for later use.

Preparing the SSH key pair on Linux

If you are on a linux box, you can generate the key pair using ssh-keygen. The key pair will be generated and stored under ~/.ssh/

Logging in to the Shared Services done by using SSH key pairs. The public SSH key is provided at the time of deployment (or can be updated later), this then allows the Shared Service Administrator to login to the Virtual Machines using his/her private SSH key.

Adding SSH key during Shared Service deployment

Adding or updating SSH key after Shared Service deployment

If you do not have the private SSH key, or need to update the SSH key pair associated with a deployment you can do so using an operation on the shared service instance.

Logging in via SSH

You can now use your private SSH key to login to the Virtual Machines. To find the hostnames of the machines go to the Shared Service Instances and look under Virtual Machine Perspective

Then use your SSH client to login. In this case for linux or on a Mac we can use the command line. ssh -i [path_to_private_ssh_key] virtuser@[hostname]

For windows you can use a tool such as putty.

Troubleshooting
