# OCS Submission Retrieval Store

> [!NOTE]
> **Not supported for SaaS instances**
> 
> OCS is available only for on-premise / private cloud instances of Hyperscience.

> [!WARNING]
> **Support deprecated in v43, will end in v46**
> 
> The use of OCS submission retrieval stores will no longer be supported in v46. While you can continue to use OCS submission retrieval stores until your upgrade to v46, we recommend migrating to a supported submission retrieval storage option as soon as possible. For a list of supported options, see [Submission Retrieval Storage Overview](/deployment/docs/submission-retrieval-storage-overview).

You can configure the connection to your OCS submission retrieval store in your flow’s Submission Initialization Block or Submission Bootstrap Block. To do so, follow the instructions in the “Submission Initialization” or “Submission Bootstrap” section of the “Flow Blocks” article for your version of Hyperscience ( [v38](/v38/docs/flow-blocks#submission-initialization) | [v39](/v39/docs/flow-blocks#submission-initialization) | [v40](/v40/docs/flow-blocks#submission-initialization) | [v41](/v41/docs/flow-blocks#submission-initialization) | [v42](/v42/docs/flow-blocks#submission-bootstrap) | [v43](/v43/docs/flow-blocks#submission-bootstrap) ).

If you originally configured your OCS submission retrieval store in v32 or earlier, the relevant settings are in your application’s “.env” file:

```powershell
OCS_USERNAME=<username>
OCS_PASSWORD=<password>
OCS_HOST_URL=://<host>/_dav/cs/idcplg
OCS_SSL_CERT=SKIP
```
