Register and Scan Oracle source

This article outlines how to register an Oracle data base in Purview and set up a scan.

Supported capabilities

The Oracle source supports Full scan to extract metadata from an Oracle database and fetches Lineage between data assets.


  1. Set up the latest self-hosted integration runtime. For more information, seeĀ Create and configure a self-hosted integration runtime.

  2. Make sure JDK 11 is installed on your virtual machine where self-hosted integration runtime is installed.

  3. Make sure "Visual C++ Redistributable 2012 Update 4" is installed on the self-hosted integration runtime machine. If you don't yet have it installed, download it from here.

  4. You will have to manually download an Oracle JDBC driver from here on your virtual machine where self-hosted integration runtime is running.


    The driver should be accessible to all accounts in the VM. Do not install it in a user account.

  5. Supported Oracle database versions are 6i to 19c.

  6. User permission: A read-only access to system tables is required. The user should have permission to create a session as well as role SELECT_CATALOG_ROLE assigned. Alternatively, the user may have SELECT permission granted for every individual system table that this connector queries metadata from:

    grant create session to [user];
    grant select on all_users to [user];
    grant select on dba_objects to [user];
    grant select on dba_tab_comments to [user];
    grant select on dba_external_locations to [user];
    grant select on dba_directories to [user];
    grant select on dba_mviews to [user];
    grant select on dba_clu_columns to [user];
    grant select on dba_tab_columns to [user];
    grant select on dba_col_comments to [user];
    grant select on dba_constraints to [user];
    grant select on dba_cons_columns to [user];
    grant select on dba_indexes to [user];
    grant select on dba_ind_columns to [user];
    grant select on dba_procedures to [user];
    grant select on dba_synonyms to [user];
    grant select on dba_views to [user];
    grant select on dba_source to [user];
    grant select on dba_triggers to [user];
    grant select on dba_arguments to [user];
    grant select on dba_sequences to [user];
    grant select on dba_dependencies to [user];
    grant select on dba_type_attrs to [user];
    grant select on V_$INSTANCE to [user];
    grant select on v_$database to [user];

Setting up authentication for a scan

The only supported authentication for an Oracle source is Basic authentication.

Register an Oracle source

To register a new Oracle source in your data catalog, do the following:

  1. Navigate to your Purview account.

  2. Select Data Map on the left navigation.

  3. Select Register

  4. On Register sources, select Oracle. Select Continue.

    register sources

On the Register sources (Oracle) screen, do the following:

  1. Enter a Name that the data source will be listed within the Catalog.

  2. Enter the Host name to connect to an Oracle source. This can either be:

    • A host name used by JDBC to connect to the database server. For for example, or
    • IP address. For for example, or
    • Its fully qualified JDBC connection string. For for example,
  3. Enter the Port number used by JDBC to connect to the database server (1521 by default for Oracle).

  4. Enter the Oracle service name used by JDBC to connect to the database server.

  5. Select a collection or create a new one (Optional)

  6. Finish to register the data source.

Creating and running a scan

To create and run a new scan, do the following:

  1. In the Management Center, click on Integration runtimes. Make sure a self-hosted integration runtime is set up. If it is not set up, use the steps mentioned here to create a self-hosted integration runtime.

  2. Navigate to Sources.

  3. Select the registered Oracle source.

  4. Select + New scan.

  5. Provide the below details:

    a. Name: The name of the scan

    b. Connect via integration runtime: Select the configured self-hosted integration runtime

    c. Credential: Select the credential to connect to your data source. Make sure to:

    • Select Basic Authentication while creating a credential.
    • Provide the user name used by JDBC to connect to the database server in the User name input field
    • Store the user password used by JDBC to connect to the database server in the secret key.

    d. Schema: List subset of schemas to import expressed as a semicolon separated list. For example, schema1; schema2. All user schemas are imported if that list is empty. All system schemas (for example, SysAdmin) and objects are ignored by default. When the list is empty, all available schemas are imported. Acceptable schema name patterns using SQL LIKE expressions syntax include using %, for example. A%; %B; %C%; D

    • start with A or
    • end with B or
    • contain C or
    • equal D

    Usage of NOT and special characters are not acceptable.

  6. Driver location: Specify the path to the JDBC driver location in your VM where self-host integration runtime is running. This should be the path to valid JAR folder location.


    The driver should be accessible to all accounts in the VM. Please do not install in a user account.

  7. Maximum memory available: Maximum memory (in GB) available on customer's VM to be used by scanning processes. This is dependent on the size of SAP S/4HANA source to be scanned.


    As a thumb rule, please provide 1GB memory for every 1000 tables

    scan oracle

  8. Click on Continue.

  9. Choose your scan trigger. You can set up a schedule or ran the scan once.

  10. Review your scan and click on Save and Run.

Viewing your scans and scan runs

  1. Navigate to the management center. Select Data sources under the Sources and scanning section.

  2. Select the desired data source. You will see a list of existing scans on that data source.

  3. Select the scan whose results you are interested to view.

  4. This page will show you all of the previous scan runs along with metrics and status for each scan run. It will also display whether your scan was scheduled or manual, how many assets had classifications applied, how many total assets were discovered, the start and end time of the scan, and the total scan duration.

Manage your scans

To manage or delete a scan, do the following:

  1. Navigate to the management center. Select Data sources under the Sources and scanning section then select on the desired data source.

  2. Select the scan you would like to manage. You can edit the scan by selecting Edit.

  3. You can delete your scan by selecting Delete.
