# Settings

The Settings tab provides post-provisioning configuration options for your Oracle database service. Changes here affect service behaviour without requiring a new provisioning.

## What settings are available in the General section?

| Setting                              | Description                                                                                                                                                  |

| **Database settings (Timezone)**     | Choose a new timezone for your database service from the dropdown.                                                                                           |
| **Enable delete protection**         | Toggle to prevent accidental deletion (disabled by default). When enabled, the Delete action is blocked.                                                     |
| **Enable stop protection**           | Toggle to prevent accidental stop (disabled by default). When enabled, the Stop action is blocked.                                                           |

## How do I update the maintenance window from the Settings tab?

In the **Maintenance Window** section, set:

* **Start day** — day of the week for the maintenance window.
* **Start time** — time of day to begin maintenance.
* **Duration** — length of the window (in 30-minute increments).

Click **Save** to apply the updated schedule.

***

## How do I enable or disable Performance Insights?

You must first create a **Monitoring Performance Insights Infrastructure** in the **Monitoring Performance Insights Infrastructure** application under the **DB Services** app family.

Once the infrastructure is deployed, toggle the **Performance Insights** button in the **Monitoring** section of the Settings tab to enable or disable it for this service. When enabled, Performance Insights analyses database load to identify bottlenecks and performance improvement areas. For more details, see the [Monitoring tab](/tessell/database-engines/tessell-for-oracle/db-services/my-services/database-service-home-page/monitoring.md).

***

## What does the Observability section show?

The **Observability** section shows the alert policies currently applied to your service.

* Click **View details** on the **Alert Policies** panel to see a full breakdown:
  * **Notification Channels** — where alerts are delivered (e.g., Slack channels, email addresses).
  * **Alert Metrics** — the specific conditions that trigger alerts (e.g., Node Down, DB Service Node Down) with severity levels (e.g., Critical).
  * **Metric & Notification Policies** — underlying policy names and metric types per alert group.

To modify policies or create new alert profiles, navigate to the [Observability app](/tessell/app-families/observability-doc.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://docs.tessell.com/tessell/database-engines/tessell-for-oracle/db-services/my-services/database-service-home-page/settings.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.
