# Distribute and activate the parcel

Before you can add the Data Optimizer service to your cluster, you must first distribute the `pdso` parcel to all the nodes in the cluster and then activate the parcel.

1. Log into Cloudera Manager Admin Console and navigate to **Hosts** > **Parcels**.
2. Find the `pdso` parcel.

   The status of the parcel should be **Downloaded**.
3. If you do not see the `pdso` parcel, click **Check for New Parcels** at the top of the Parcels page.
4. Click **Distribute** for the `pdso` parcel.

   The distribution process starts immediately. Depending on the size of the cluster, this process may take several minutes or more. Allow it to complete.

   The parcel status changes to **Distributed**.
5. Click **Activate** for the `pdso` parcel.

   The activation process starts immediately. Depending on the size of the cluster, this process may take several minutes or more. Allow it to complete.

   The parcel status changes to **Activated**.

The Data Optimizer service is ready to be added to your Cloudera cluster.
