# Manage engines

You can manage your engines and load-balancing groups by going to Settings & Info → Settings → **Integrations** → **Engines**.

You can view engine names, hosts, status, connection, and other engine information.

{% hint style="info" %}

### Note

In the **Name** column, if the service name starts with a `d1` prefix, it is a multiple engine.
{% endhint %}

You can do the following:

| Load-Balancing Group   | <p>Separate load-balancing groups have several uses. For example:</p><ul><li>Use separate load-balancing groups for different integrations and instances. Create Load-Balancing groups for certain tasks, which can help segregate the infrastructure of critical integrations.</li><li>Managed Security Service Providers may want to split internal engines and SaaS product engines.</li><li>If you have multiple AWS accounts that are not connected and do not want a single point of failure for AWS integrations that use STS.</li></ul><p>You can do the following:</p><ul><li><p>Add/remove engines to a load-balancing group</p><p>You can only add the engine to the load-balancing group after you have connected the engine.</p><p>If you want to remove the last engine from a specific load-balancing group and one or more integration instances use that engine, you will get an error. Before moving the engine, in the integration instance settings, you need to update the <strong>Run on</strong> field to a different engine or no engine.</p></li><li><p>Create load-balancing groups</p><p>When selecting Load-Balancing Group → <strong>Add to new group</strong>, you can create multiple load-balancing groups and decide which engines are part of each group.</p><p>Users can move an engine from one group to another. A group will be deleted when the last engine is removed from it.</p><p>Each engine can only belong to one group.</p></li></ul> |
| Upgrade Engine         | Relevant for Shell installation only. If you didn't install an engine using the Shell installation you will need to remove the engine and do a fresh installation.

To remove the engine from your remote machine, see [Remove an engine](/cortex-xsoar-8-on-prem/8.9/configure-cortex-xsoar/engines/remove-an-engine.md).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsoar-8-on-prem/8.9/configure-cortex-xsoar/engines/manage-engines.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
