Harvesting from Oracle Object Storage
Harvesting is a process that extracts technical metadata from your data assets into your data catalog. A Data Asset represents a data source. For example: a database, an object store, a file or document store, a message queue, or an application.
In this tutorial, you:
- Allow Data Catalog to access any object in your Oracle Object Storage, in any bucket, in any compartment within the tenancy where the policy is created.
- Create an Oracle Object Storage data asset.
- Add one default connection for the data asset.
- Harvest the data asset by running the harvest job immediately.
Before You Begin
To successfully perform this tutorial, you must have the following:
- An Oracle Cloud Infrastructure account. See signing up for Oracle Cloud Infrastructure.
- Access to use the Data Catalog resources. See prerequisites and policy examples.
- A created data catalog instance. See creating a data catalog instance.
1. Creating an Access Policy
You create a policy to allow Data Catalog to access your Object Storage resources.
At a minimum, you must have READ
permission for the Object Storage
aggregate resource type object-family
, or for all the individual
resource types objectstorage-namespaces
, buckets
,
and objects
.
To create an access policy to grant READ
permission to the Object
Storage aggregate resource type object-family
, perform the
following steps:

2. Creating a Data Asset
You are now ready to register your Oracle Object Storage data sources with Data Catalog as a data asset .
To create an Oracle Object Storage data asset, perform the following steps:

3. Adding a Connection
After creating the Oracle Object Storage data asset, you create a connection for the data asset.
To create a connection for your Oracle Object Storage data asset, perform the following steps:

4. Harvesting the Data Asset
You are now ready to harvest your Oracle Object Storage data asset.
To harvest your Oracle Object Storage data asset, perform the following steps:

What's Next
Now, you can explore the data asset, create a glossary, and link terms and tags to data objects.
