# Populate Cache Batch Process

You can populate and initialize the cache by running batch jobs from the CMT Administration screen.

For an overview of Digital Commerce caching, see [Digital Commerce API Caching](https://developer.salesforce.com/docs/industries/cme/guide/comms-t-digital-commerce-api-caching.md).

The following table describes the purpose of each of the jobs:

    ![Populate API cache](https://developer.salesforce.com/docs/media/populate_api_cache_3.png)

3.  Make any of the following optional settings:

    - To specify a particular cache job to run, check the box next to the job name.

    - To specify that all of the cache jobs should run, check the box next to **Name**.

    - To specify that you want to populate the cache with information from one or more catalogs, select the checkbox next to each catalog.

    - To specify that you want to populate the cache with information from all active catalogs, select the **All** checkbox under Catalogs.

    - Use the **Effective Start Date** and **Expiration Date** fields to specify the length of time the cache is active.

4.  Click **OK**. You receive a confirmation about whether the job or jobs have run successfully.

    The Populate API Cache page shows only those catalogs marked as Active

    **note:** You can also run the Digital Commerce API cache jobs remotely using APEX. See [Running Maintenance and Digital Commerce Cache Jobs Remotely](https://developer.salesforce.com/docs/industries/cme/guide/comms-t-running-maintenance-and-digital-commerce-cache-jobs-remotely.md).
