If you have the Admin role or Editor in a project, you can perform management tasks for environments.

• Create an environment definition
• Customize an environment definition
• Change the environment definition of a notebook
• Stop active runtimes
• Track capacity unit consumption of runtimes

Changing the environment of a notebook

You can switch environments for different reasons, for example, you can:

• Select an environment with more processing power or more RAM
• Switch from using an environment that runs in Cloud Pak for Data as a Service to an environment that runs in a Satellite location
• Change from using an environment without Spark to a Spark environment
• Change from using a Spark environment provided through IBM Watson Studio to using IBM Analytics Engine provisioned through IBM Cloud

You can change the environment of a notebook:

• From the notebook opened in edit mode:

  1. Save your notebook changes.
  2. Click the Notebook Info icon () from the notebook toolbar and then click Environment. A short description of the environment is displayed.
  3. Select another runtime with the compute power and memory capacity from the list under Environments.
     The active runtime is stopped and the runtime you selected is instantiated.
  4. Select Change environment.
     This stops the active runtime and starts the newly selected environment.

• From the Assets page of your project:

  1. Select the notebook in the Notebooks section, click Actions > Change Environment and select another environment. The kernel must be stopped before you can change the environment. This new runtime environment will be instantiated the next time the notebook is opened for editing.
