# Reindex a Tenant Database

Reindex a tenant database in a Cortex XSOAR 6.15 multi-tenant environment.

If an index is corrupted and the tenant service is not starting or if data is missing, you might need to reindex the database. Depending on the volume of data, it may take some time for the reindexing to complete. Follow these steps to reindex the entire database of a tenant.

{% hint style="info" %}
Reindexing a tenant requires machine resources and might have a temporary impact on the performance of other tenants.

By default, audits are not reindexed. See [Reindex the Audit Log](/xsoar-6-administrator-guide/6.14/customize-cortex-xsoar/customize-and-configure-cortex-xsoar/manage-data/reindex-the-audit-log.md) for instructions.
{% endhint %}

1. If the tenant is running, stop the tenant process:

   Go to Settings → ACCOUNT MANAGEMENT → **Accounts**, select the tenant account, and click **Stop**.
2. Back up the tenant index directory, located at: `/var/lib/demisto/tenants/acc_<TENANT_NAME>/data/demistoidx`.

   The backup of the index directory should not be stored under `/var/lib/demisto/tenants/acc_<TENANT_NAME>`.
3. Delete the tenant index folder:

   `sudo rm -rf /var/lib/demisto/tenants/acc_<TENANT_NAME>/data/demistoidx`
4. Restart the tenant process:

   Go to Settings → ACCOUNT MANAGEMENT → **Accounts**, select the tenant account, and click **Start**.

   The host will automatically reindex the tenant account.
5. Log in to your Cortex XSOAR tenant instance and verify that the reindex process was successful.

   All of your data should appear, for example, incidents, playbooks, automations, and so on. If there are any issues, contact the Cortex XSOAR support team.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsoar-6-multi-tenant-guides/6.15/configure-multi-tenant/configure-the-multi-tenant-deployment/reindex-a-tenant-database.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
