Use stored cloud service credentials to access the cloud service for data loading, for querying external data residing in the cloud, or for other cases when you use DBMS_CLOUD procedures with a credential_name parameter. This procedure is overloaded:

• Use the Oracle Cloud Infrastructure-related parameters, including: user_ocid, tenancy_ocid, private_key, and fingerprint only when you are using Oracle Cloud Infrastructure Signing Keys authentication.

• Use the params parameter for one of the following:

  • Amazon Resource Names (ARNs) credentials

  • Google Analytics or Google BigQuery credentials

  • Vault secret credentials for use with a supported vault:

    • Oracle Cloud Infrastructure Vault
    • Azure Key Vault
    • AWS Secrets Manager
    • GCP Secret Manager

Syntax

DBMS_CLOUD.CREATE_CREDENTIAL (
      credential_name   IN VARCHAR2,
      username          IN VARCHAR2,
      password          IN VARCHAR2 DEFAULT NULL);


DBMS_CLOUD.CREATE_CREDENTIAL (
      credential_name IN VARCHAR2,
      user_ocid       IN VARCHAR2,
      tenancy_ocid    IN VARCHAR2,
      private_key     IN VARCHAR2,
      fingerprint     IN VARCHAR2);


DBMS_CLOUD.CREATE_CREDENTIAL (
      credential_name  IN VARCHAR2,
      params           IN CLOB DEFAULT);

Parameters

Usage Notes

• This operation stores the credentials in the database in an encrypted format.

• You can see the credentials in your schema by querying the user_credentials table.

• The ADMIN user can see all the credentials by querying the dba_credentials table.

• You only need to create credentials once unless your cloud service credentials change. Once you store the credentials you can then use the same credential name for DBMS_CLOUD procedures that require a credential_name parameter.

• This procedure is overloaded. If you provide one of the key based authentication attributes, user_ocid, tenancy_ocid, private_key, or fingerprint, the call is assumed to be an Oracle Cloud Infrastructure Signing Key based credential.

• You can list credentials from the view ALL_CREDENTIALS. For example, run the following command to list credentials:

  SELECT credential_name, username, comments FROM all_credentials;

Oracle Cloud Infrastructure Credentials (Auth Tokens)

For Oracle Cloud Infrastructure the username is your Oracle Cloud Infrastructure user name. The password is your Oracle Cloud Infrastructure auth token. See Working with Auth Tokens.

For example:

BEGIN
  DBMS_CLOUD.CREATE_CREDENTIAL(
    credential_name => 'DEF_CRED_NAME',
    username => 'adb_user@example.com',
    password => 'password' );
END;
/

Use Auth Token based credentials when you are authenticating calls to OCI Object Storage. For calls to any other type of Oracle Cloud Infrastructure cloud service, use Oracle Cloud Infrastructure Signing Key Based Credentials.

For OCI Object Storage, username parameter value must include the Identity domain and the user name from your profile. You can find the Identity domain associated with a user in the Oracle Cloud Infrastructure Console.

For example:

oracleidentitycloudservice/adb_user@example.com

With the default Identity domain you are not required to include the domain name Default. For example:

adb_user@example.com

Oracle Cloud Infrastructure Signing Key Based Credentials

Use the Oracle Cloud Infrastructure signing key related parameters, including: user_ocid, tenancy_ocid, private_key, and fingerprint with Oracle Cloud Infrastructure Signing Keys authentication.

For example:

BEGIN
   DBMS_CLOUD.CREATE_CREDENTIAL (
       credential_name => ‘OCI_KEY_CRED’,
       user_ocid       => ‘ocid1.user.oc1..aaaaaaaauq54mi7zdyfhw33ozkwuontjceel7fok5nq3bf2vwetkpqsoa’,
       tenancy_ocid    => ‘ocid1.tenancy.oc1..aabbbbbbaafcue47pqmrf4vigneebgbcmmoy5r7xvoypicjqqge32ewnrcyx2a’,
       private_key     => ‘MIIEogIBAAKCAQEAtUnxbmrekwgVac6FdWeRzoXvIpA9+0r1.....wtnNpESQQQ0QLGPD8NM//JEBg=’,
       fingerprint     => ‘f2:db:f9:18:a4:aa:fc:94:f4:f6:6c:39:96:16:aa:27’);
END;
/

Private keys generated with a passphrase are not supported. You need to generate the private key without a passphrase. See How to Generate an API Signing Key for more information.

Oracle Cloud Infrastructure Object Storage Classic Credentials

If your source files reside in Oracle Cloud Infrastructure Object Storage Classic, the username is your Oracle Cloud Infrastructure Classic user name and the password is your Oracle Cloud Infrastructure Classic password.

Amazon Web Services (AWS) Credentials

If your source files reside in Amazon S3 or you are calling an AWS API, the username is your AWS access key ID and the password is your AWS secret access key. See AWS Identity and Access Management.

Amazon S3-Compatible Credentials

AWS Amazon Resource Names (ARN) Credentials

If your source files reside in Amazon S3 or you are calling an AWS API, use params to specify the parameters for the Amazon Resource Names (ARN).

For example:

BEGIN DBMS_CLOUD.CREATE_CREDENTIAL(
        credential_name      => 'MY_CRED',
        params               => JSON_OBJECT(
               'aws_role_arn'      value 'arn:aws:iam::123456:role/AWS_ROLE_ARN',
               'external_id_type'  value 'database_ocid'));
END;
/

GitHub Personal Access Token

If your source files reside in a GitHub repository or you are calling a GitHub API, the username is your GitHub email and the password is your GitHub personal access token. See Creating a personal access token for more information.

For example:

BEGIN
  DBMS_CLOUD.CREATE_CREDENTIAL(
    credential_name => 'MY_GITHUB_CRED',
    username => 'user@example.com',
    password => 'your_personal_access_token' );
END;
/

Google Analytics or Google BigQuery Credentials

If you are accessing Google Analytics or Google BigQuery, use the params parameter to specify the Google OAuth 2.0 credential parameters.

For example:

BEGIN DBMS_CLOUD.CREATE_CREDENTIAL(
      credential_name => 'GOOGLE_BIGQUERY_CRED',
      params => JSON_OBJECT('gcp_oauth2' value 
                                  JSON_OBJECT(
                                       'client_id'     value 'client_id',
                                       'client_secret' value 'client_secret',
                                       'refresh_token' value 'refresh_token' )));
END;
/

Vault Secret Credentials with Oracle Cloud Infrastructure Vault

To create vault secret credentials with Oracle Cloud Infrastructure Vault, use the params parameter to specify the required parameters:

• username: Specifies the username of any type of username/password credential such as the username of OCI Swift password. For example, if you have a Swift credential with username as “scott” and password as “password”, provide “scott” as the username parameter.

• secret_id: Is the vault secret ID. Specify the secret_id value as the vault secret OCID. See Overview of Vault for more information.

• region: Is an optional parameter that specifies the oracle cloud region identifier. The region, when specified, indicates the location where Oracle Cloud Infrastructure Vault secret is located.

  By default, CREATE_CREDENTIAL uses the region mapped from the region key in the secret_id. An example of a region is us-ashburn-1.

  See Regions and Availability Domains for a complete list of regions.

For example:

BEGIN DBMS_CLOUD.CREATE_CREDENTIAL(
    credential_name => 'OCI_SECRET_CRED',
    params => JSON_OBJECT( 
                'username'   value 'scott',
                'region'     value 'us-ashburn-1',
                'secret_id'  value 'ocid1.vaultsecret.co1.ap-mumbai-1.example..aaaaaaaauq5ok5nq3bf2vwetkpqsoa'));
END;
/

Notes for using an Oracle Cloud Infrastructure Vault secret to store vault secrets:

• When you use an Oracle Cloud Infrastructure Vault, on the Autonomous Database instance you must enable principal authentication with DBMS_CLOUD_ADMIN.ENABLE_RESOURCE_PRINCIPAL.

Usage Note

The default record delimiter is detected newline. With detected newline, DBMS_CLOUD tries to automatically find the correct newline character to use as the record delimiter. DBMS_CLOUD first searches for the Windows newline character \r\n. If it finds the Windows newline character, this is used as the record delimiter for all files in the procedure. If a Windows newline character is not found, DBMS_CLOUD searches for the UNIX/Linux newline character \n, and if it finds one it uses \n as the record delimiter for all files in the procedure. If the source files use a combination of different record delimiters, you may encounter an error such as, "KUP-04020: found record longer than buffer size supported". In this case, you need to either modify the source files to use the same record delimiter or only specify the source files that use the same record delimiter.

See DBMS_CLOUD Package Format Options for information on the recorddelmiter format option.

Examples

BEGIN
    DBMS_CLOUD.CREATE_CREDENTIAL(
            credential_name => 'DEF_CRED_NAME',
            username        => 'user_name@oracle.com',

Usage Notes

• As with other data files, Avro, ORC, and Parquet data loads generate logs that are viewable in the tables dba_load_operations and user_load_operations. Each load operation adds a record to dba[user]_load_operations that indicates the table containing the logs.

  The log table provides summary information about the load.

• For Avro, ORC, or Parquet, when the format parameter type is set to the value avro, orc, or parquet, the BADFILE_TABLE table is always empty.

  • For Parquet files, PRIMARY KEY constraint errors throw an ORA error.

  • If data for a column encounters a conversion error, for example, the target column is not large enough to hold the converted value, the value for the column is set to NULL. This does not produce a rejected record.

The source and target bucket or folder can be in the same or different Cloud Object store provider.

When the source and target are in distinct Object Stores or have different accounts with the same cloud provider, you can give separate credential names for the source and target locations.

The source credential name is by default also used by the target location when target credential name is not provided.

Syntax

DBMS_CLOUD.COPY_OBJECT (
    source_credential_name  IN  VARCHAR2 DEFAULT NULL,
    source_object_uri       IN  VARCHAR2,
    target_object_uri       IN  VARCHAR2,
    target_credential_name  IN  VARCHAR2 DEFAULT NULL

Parameters

Example

BEGIN 
DBMS_CLOUD.COPY_OBJECT (
    source_credential_name => 'OCI_CRED',
    source_object_uri    => 'https://objectstorage.us-phoenix-1.oraclecloud.com/n/namespace-string/b/bucketname1/bgfile.csv',

    table_name       IN VARCHAR2,
    column_list      IN CLOB,
    params           IN CLOB);

Parameters

Usage Notes

• DEFAULT attributes: The column_list can include DEFAULT clause, which functions like the DEFAULT clause in an ordinary CREATE TABLE. See CREATE TABLE for information on the behavior of the DEFAULT clause.

• Use DROP TABLE to drop a Cloud Table. Cloud Tables do not support the recycle bin.

  For example:

  DROP TABLE CLOUD_TAB1; 

• You can grant SELECT, INSERT, and UPDATE privileges for a Cloud Table. No other privileges can be granted to a Cloud Table.

  See Configuring Privilege and Role Authorization for more information.

Examples

EXEC DBMS_CLOUD.CREATE_CLOUD_TABLE( 'CLOUD_TAB1', 'I INTEGER, J INTEGER' );

BEGIN
  DBMS_CLOUD.CREATE_CLOUD_TABLE(
   table_name  => 'CLOUD_TABLE_WITH_DEFAULT',

Usage Notes

• You cannot call this procedure with both partitioning_clause and file_uri_list parameters.

• Specifying the column_list parameter is optional with structured data files, including Avro, Parquet, or ORC data files. If column_list is not specified, the format parameter partition_columns option must include both name and type.

• The column_list parameter is required with unstructured data files, such as CSV text files.

• The procedure DBMS_CLOUD.CREATE_EXTERNAL_PART_TABLE supports external partitioned files in the supported cloud object storage services, including:

  • Oracle Cloud Infrastructure Object Storage

  • Azure Blob Storage or Azure Data Lake Storage

  • Amazon S3

  • Amazon S3-Compatible, including: Oracle Cloud Infrastructure Object Storage, Google Cloud Storage, and Wasabi Hot Cloud Storage.

  • GitHub Repository

  See DBMS_CLOUD URI Formats for more information.

• The procedure DBMS_CLOUD.CREATE_EXTERNAL_PART_TABLE supports external partitioned files in directories, either in a local file system or in a network file system.

• When you call DBMS_CLOUD.CREATE_EXTERNAL_PART_TABLE with the file_uri_list parameter, the types for columns specified in the Cloud Object Store file name must be one of the following types:

  VARCHAR2(n)
  NUMBER(n)
  NUMBER(p,s)
  NUMBER
  DATE
  TIMESTAMP(9)

• The default record delimiter is detected newline. With detected newline, DBMS_CLOUD tries to automatically find the correct newline character to use as the record delimiter. DBMS_CLOUD first searches for the Windows newline character \r\n. If it finds the Windows newline character, this is used as the record delimiter for all files in the procedure. If a Windows newline character is not found, DBMS_CLOUD searches for the UNIX/Linux newline character \n, and if it finds one it uses \n as the record delimiter for all files in the procedure. If the source files use a combination of different record delimiters, you may encounter an error such as, "KUP-04020: found record longer than buffer size supported". In this case, you need to either modify the source files to use the same record delimiter or only specify the source files that use the same record delimiter.

  See DBMS_CLOUD Package Format Options for information on the recorddelmiter format option.

• The external partitioned tables you create with DBMS_CLOUD.CREATE_EXTERNAL_PART_TABLE include two invisible columns file$path and file$name. These columns help identify which file a record is coming from.

  • file$path: Specifies the file path text up to the beginning of the object name.

  • file$name: Specifies the object name, including all the text that follows the bucket name.

Examples

Example using the partitioning_clause parameter:

BEGIN  
   DBMS_CLOUD.CREATE_EXTERNAL_PART_TABLE(

Usage Notes

• The procedure DBMS_CLOUD.CREATE_EXTERNAL_TABLE supports external partitioned files in the supported cloud object storage sources, including:

  • Oracle Cloud Infrastructure Object Storage

  • Azure Blob Storage or Azure Data Lake Storage

  • Amazon S3

  • Amazon S3-Compatible, including: Oracle Cloud Infrastructure Object Storage, Google Cloud Storage, and Wasabi Hot Cloud Storage.

  • GitHub Repository

  • Oracle Cloud Infrastructure Object Storage with Pre-Authenticated Request (PAR) URLs

  The credential is a table level property; therefore, the external files must be on the same object store.

  See DBMS_CLOUD URI Formats for more information.

• The default record delimiter is detected newline. With detected newline, DBMS_CLOUD tries to automatically find the correct newline character to use as the record delimiter. DBMS_CLOUD first searches for the Windows newline character \r\n. If it finds the Windows newline character, this is used as the record delimiter for all files in the procedure. If a Windows newline character is not found, DBMS_CLOUD searches for the UNIX/Linux newline character \n, and if it finds one it uses \n as the record delimiter for all files in the procedure. If the source files use a combination of different record delimiters, you may encounter an error such as, "KUP-04020: found record longer than buffer size supported". In this case, you need to either modify the source files to use the same record delimiter or only specify the source files that use the same record delimiter.

  See DBMS_CLOUD Package Format Options for information on the recorddelimiter format option.

BEGIN  
   DBMS_CLOUD.CREATE_EXTERNAL_TABLE(

      query             IN CLOB DEFAULT NULL,
      operation_id      OUT NOCOPY NUMBER);

Parameters

Usage Notes:

• The query parameter value that you supply can be an advanced query, if required, such as a query that includes joins or subqueries.

• Depending on the format parameter specified, DBMS_CLOUD.EXPORT_DATA outputs the results of the specified query on the Cloud Object Store or to a directory location in one of these formats:

  • CSV, JSON, Parquet, or XML files.

    See Export Data to Object Store as Text and Export Data to a Directory for more information on using DBMS_CLOUD.EXPORT_DATA with CSV, JSON, Parquet, or XML output files.

  • Using the ORACLE_DATAPUMP access driver to write data to a dump file.

• For CSV, JSON, or XML output, by default when a generated file contains 10MB of data a new output file is created. However, if you have less than 10MB of result data you may have multiple output files, depending on the database service and the number of ECPUs (OCPUs if your database uses OCPUs) for the Autonomous Database instance.

  See File Naming for Text Output (CSV, JSON, Parquet, or XML) for more information.

  The default output file chunk size is 10MB for CSV, JSON, or XML. You can change this value with the format parameter maxfilesize option. See DBMS_CLOUD Package Format Options for EXPORT_DATA for more information.

• For Parquet output, each generated file is less than 128MB and multiple output files may be generated. However, if you have less than 128MB of result data, you may have multiple output files depending on the database service and the number of ECPUs (OCPUs if your database uses OCPUs) for the Autonomous Database instance.

  See File Naming for Text Output (CSV, JSON, Parquet, or XML) for more information.

Usage Notes for ORACLE_DATAPUMP Output (DBMS_CLOUD.EXPORT_DATA with format parameter type option datapump):

• EXPORT_DATA uses DATA_PUMP_DIR as the default logging directory. So the write privilege on DATA_PUMP_DIR is required when using ORACLE_DATAPUMP output.

• Autonomous Database export using DBMS_CLOUD.EXPORT_DATA with format parameter type option datapump only supports Oracle Cloud Infrastructure Object Storage, Oracle Cloud Infrastructure Object Storage Classic object stores or directory output.

• When you specify DBMS_CLOUD.EXPORT_DATA with the format parameter type option datapump, the credential_name parameter value cannot be an OCI resource principal.

• Oracle Data Pump divides each dump file part into smaller chunks for faster uploads. The Oracle Cloud Infrastructure Object Storage console shows multiple files for each dump file part that you export. The size of the actual dump files will be displayed as zero (0) and its related file chunks as 10mb or less. For example:

  exp01.dmp
  exp01.dmp_aaaaaa
  exp02.dmp
  exp02.dmp_aaaaaa

  Downloading the zero byte dump file from the Oracle Cloud Infrastructure console or using the Oracle Cloud Infrastructure CLI will not give you the full dump files. To download the full dump files from the Object Store, use a tool that supports Swift such as curl, and provide your user login and Swift auth token.

  curl -O -v -X GET -u 'user1@example.com:auth_token' \
     https://swiftobjectstorage.us-ashburn-1.oraclecloud.com/v1/namespace-string/bucketname/exp01.dmp

  If you import a file with the DBMS_CLOUD procedures that support the format parameter type with the value 'datapump', you only need to provide the primary file name. The procedures that support the 'datapump' format type automatically discover and download the chunks.

  When you use DBMS_CLOUD.DELETE_OBJECT, the procedure automatically discovers and deletes the chunks when the procedure deletes the primary file.

• The DBMS_CLOUD.EXPORT_DATA procedure creates the dump file(s) from the file_uri_list values that you specify, as follows:

  • As more files are needed, the procedure creates additional files from the file_uri_list.

  • The procedure does not overwrite files. If a dump file in the file_uri_list exists, DBMS_CLOUD.EXPORT_DATA reports an error.

  • DBMS_CLOUD.EXPORT_DATA does not create buckets.

• The number of dump files that DBMS_CLOUD.EXPORT_DATA generates is determined when the procedure runs. The number of dump files that are generated depends on the number of file names you provide in the file_uri_list parameter, as well as on the number of Autonomous Database OCPUs available to the instance, the service level, and the size of the data.

  For example, if you use a 1 OCPU Autonomous Database instance or the low service, then a single dump file is exported with no parallelism, even if you provide multiple file names. If you use a 4 OCPU Autonomous Database instance with the medium or high service, then the jobs can run in parallel and multiple dump files are exported if you provide multiple file names.

• The dump files you create with DBMS_CLOUD.EXPORT_DATA cannot be imported using Oracle Data Pump impdp. Depending on the database, you can use these files as follows:

  • On an Autonomous Database, you can use the dump files with the DBMS_CLOUD procedures that support the format parameter type with the value 'datapump'. You can import the dump files using DBMS_CLOUD.COPY_DATA or you can call DBMS_CLOUD.CREATE_EXTERNAL_TABLE to create an external table.

  • On any other Oracle Database, such as Oracle Database 19c on-premise, you can import the dump files created with the procedure DBMS_CLOUD.EXPORT_DATA using the ORACLE_DATAPUMP access driver. See Unloading and Loading Data with the ORACLE_DATAPUMP Access Driver for more information.

• The query parameter value that you supply can be an advanced query, if required, such as a query that includes joins or subqueries.

Usage Notes for DBMS_CLOUD.EXPORT_DATA with Output to a Directory

• The provided directory must exist and you must be logged in as the ADMIN user or have WRITE access to the directory.

• DBMS_CLOUD.EXPORT_DATA does not create directories.

• The procedure does not overwrite files. For example, if a dump file in the file_uri_list exists, DBMS_CLOUD.EXPORT_DATA reports an error such as:

  ORA-31641: unable to create dump file  "/u02/exports/123.dmp"
  ORA-27038: created file already exists

Examples

The following example shows DBMS_CLOUD.EXPORT_DATA with the format type parameter with the value datapump:

BEGIN

To read character data from a file in Object Store:

SELECT to_clob(
     DBMS_CLOUD.GET_OBJECT(
       credential_name => 'OBJ_STORE_CRED',
       object_uri => 'https://objectstorage.us-phoenix-1.oraclecloud.com/n/namespace-string/b/bucketname/o/file.txt'))
FROM DUAL;

To add an image stored on Object Store in a BLOB in the database:

DECLARE
   l_blob BLOB := NULL;
BEGIN
   l_blob := DBMS_CLOUD.GET_OBJECT(
     credential_name => 'OBJ_STORE_CRED',
     object_uri => 'https://objectstorage.us-phoenix-1.oraclecloud.com/n/namespace-string/b/bucketname/o/MyImage.gif' );
END;
/

In this example, namespace-string is the Oracle Cloud Infrastructure object storage namespace and bucketname is the bucket name. See Understanding Object Storage Namespaces for more information.

Syntax

DBMS_CLOUD.LIST_FILES (
	directory_name      IN VARCHAR2)
       RETURN TABLE;

Parameters

Usage Notes

• To run DBMS_CLOUD.LIST_FILES with a user other than ADMIN you need to grant read privileges on the directory to that user. For example, run the following command as ADMIN to grant read privileges to adb_user:

  GRANT READ ON DIRECTORY data_pump_dir TO adb_user;

• This is a pipelined table function with return type as DBMS_CLOUD_TYPES.list_object_ret_t.

• DBMS_CLOUD.LIST_FILES does not obtain the checksum value and returns NULL for this field.

Example

This is a pipelined function that returns a row for each file. For example, use the following query to use this function:

SELECT * FROM DBMS_CLOUD.LIST_FILES('DATA_PUMP_DIR');

OBJECT_NAME       BYTES   CHECKSUM      CREATED              LAST_MODIFIED

Syntax

DBMS_CLOUD.LIST_OBJECTS (
       credential_name      IN VARCHAR2,
       location_uri         IN VARCHAR2)
   RETURN TABLE;

Parameters

Usage Notes

• Depending on the capabilities of the object store, DBMS_CLOUD.LIST_OBJECTS does not return values for certain attributes and the return value for the field is NULL in this case.

  All supported Object Stores return values for the OBJECT_NAME, BYTES, and CHECKSUM fields.

  The following table shows support for the fields CREATED and LAST_MODIFIED by Object Store:

  Object Store	CREATED	LAST_MODIFIED
  Oracle Cloud Infrastructure Native	Returns timestamp	Returns timestamp
  Oracle Cloud Infrastructure Swift	Returns NULL	Returns timestamp
  Oracle Cloud Infrastructure Classic	Returns NULL	Returns timestamp
  Amazon S3	Returns NULL	Returns timestamp
  Amazon S3-Compatible	Returns NULL	Returns timestamp
  Azure	Returns timestamp	Returns timestamp
  GitHub Repository

• The checksum value is the MD5 checksum. This is a 32-character hexadecimal number that is computed on the object contents. It is expected to have a different checksum value if OCI$RESOURCE_PRINCIPAL credential is used.

• This is a pipelined table function with return type as DBMS_CLOUD_TYPES.list_object_ret_t.

Example

This is a pipelined function that returns a row for each object. For example, use the following query to use this function:

SELECT * FROM DBMS_CLOUD.LIST_OBJECTS('OBJ_STORE_CRED', 
    'https://objectstorage.us-phoenix-1.oraclecloud.com/n/namespace-string/b/bucketname/o/');


OBJECT_NAME   BYTES              CHECKSUM                       CREATED         LAST_MODIFIED
------------ ---------- -------------------------------- --------------------- --------------------

In this example, namespace-string is the Oracle Cloud Infrastructure object storage namespace and bucketname is the bucket name. See Understanding Object Storage Namespaces for more information.

The source and target bucket or folder can be in the same or different Cloud Object store provider.

When the source and target are in distinct Object Stores or have different accounts with the same cloud provider, you can give separate credential names for the source and target locations.

The source credential name is by default also used by the target location when target credential name is not provided.

Syntax

DBMS_CLOUD.MOVE_OBJECT (
    source_credential_name  IN  VARCHAR2 DEFAULT NULL,
    source_object_uri       IN  VARCHAR2,
    target_object_uri       IN  VARCHAR2,
    target_credential_name  IN  VARCHAR2 DEFAULT NULL
);

Parameters

Example

BEGIN 
DBMS_CLOUD.MOVE_OBJECT (
    source_credential_name => 'OCI_CRED',
    source_object_uri    => 'https://objectstorage.us-phoenix-1.oraclecloud.com/n/namespace-string/b/bucketname1/bgfile.csv',
    target_object_uri    => 'https://objectstorage.us-phoenix-1.oraclecloud.com/n/namespace-string/b/bucketname2/myfile.csv'
);
END;
/

Syntax

DBMS_CLOUD.PUT_OBJECT (
       credential_name      IN VARCHAR2,
       object_uri           IN VARCHAR2,
       directory_name       IN VARCHAR2,
       file_name            IN VARCHAR2
       compression          IN VARCHAR2 DEFAULT  NULL);


DBMS_CLOUD.PUT_OBJECT (
       credential_name      IN VARCHAR2,
       object_uri           IN VARCHAR2,
       contents             IN BLOB
       compression          IN VARCHAR2 DEFAULT  NULL);

Parameters

^Footnote 2

GRANT READ ON DIRECTORY data_pump_dir TO adb_user;

Example

To handle BLOB data after in-database processing and then store the data directly into a file in the object store:

DECLARE
      my_blob_data BLOB;
BEGIN 
 /* Some processing producing BLOB data and populating my_blob_data */
DBMS_CLOUD.PUT_OBJECT(
     credential_name => 'OBJ_STORE_CRED',
     object_uri => 'https://objectstorage.us-phoenix-1.oraclecloud.com/n/namespace-string/b/bucketname/o/my_new_file',
     contents => my_blob_data)); 
END;
/

Usage Notes

Depending on your Cloud Object Storage, the size of the object you transfer is limited as follows:

Oracle Cloud Infrastructure object store does not allow writing files into a public bucket without supplying credentials (Oracle Cloud Infrastructure allows users to download objects from public buckets). Thus, you must supply a credential name with valid credentials to store an object in an Oracle Cloud Infrastructure public bucket using PUT_OBJECT.

See DBMS_CLOUD URI Formats for more information.

You can filter the list of files to be deleted using a regular expression pattern compatible with REGEXP_LIKE operator.

The source and target bucket or folder can be in the same or different Cloud Object store provider.

When the source and target are in distinct Object Stores or have different accounts with the same cloud provider, you can give separate credential names for the source and target locations.

The source credential name is by default also used by the target location when target credential name is not provided.

The first step in moving files is copying them to the target location, then deleting the source files, once they are successfully copied.

The object is renamed rather than moved if Object Store allows renaming operations between source and target locations.

DBMS_CLOUD supports GET, PUT, POST, HEAD and DELETE HTTP methods. The REST API method to be used for an HTTP request is typically documented in the Cloud REST API documentation.

By default DBMS_CLOUD REST API calls do not save results for your session. In this case you use the DBMS_CLOUD.SEND_REQUEST function to return results.

When you use DBMS_CLOUD.SEND_REQUEST and set the cache parameter to TRUE, results are saved and you can view past results in the SESSION_CLOUD_API_RESULTS view. Saving and querying historical results of DBMS_CLOUD REST API requests can help you when you need to work with your previous results in your applications.

For example, to query recent DBMS_CLOUD REST API results, use the view SESSION_CLOUD_API_RESULTS:

SELECT timestamp FROM SESSION_CLOUD_API_RESULTS;

When you save DBMS_CLOUD REST API results with DBMS_CLOUD.SEND_REQUEST the saved data is only available within the same session (connection). After the session exits, the saved data is no longer available.

Use DBMS_CLOUD.GET_API_RESULT_CACHE_SIZE and DBMS_CLOUD.SET_API_RESULT_CACHE_SIZE to view and set the DBMS_CLOUD REST API cache size, and to disable caching.

Parameters

Exceptions

Usage Notes

• If you are using Oracle Cloud Infrastructure, you must use a Signing Key based credential value for the credential_name. See CREATE_CREDENTIAL Procedure for more information.

• The optional parameters async_request_url, wait_for_states, and timeout allow you to handle long running requests. Using this asynchronous form of send_request, the function waits for the completion status specified in wait_for_states before returning. With these parameters in the send request, you pass the expected return states in the wait_for_states parameter, and you use the async_request_url parameter to specify an associated work request, the request does not return immediately. Instead, the request probes the async_request_url until the return state is one of the expected states or the timeout is exceeded (timeout is optional). If no timeout is specified, the request waits until a state found in wait_for_states occurs.

• In this example, namespace-string is the Oracle Cloud Infrastructure object storage namespace and bucketname is the bucket name. See Understanding Object Storage Namespaces for more information.

• Where: region is an endpoint region. See Object Storage API reference in API Reference and Endpoints for more information. For example, where region is: us-phoenix-1.

List Compartments Example

Shows an example using DBMS_CLOUD.SEND_REQUEST with HTTP GET method to list all compartments in the tenancy (root compartment). This example shows how to pass request headers in the DBMS_CLOUD.SEND_REQUEST.

See ListCompartments for details on the Oracle Cloud Infrastructure Identity and Access Management Service API for this example.

--
-- List compartments
--
DECLARE
  resp DBMS_CLOUD_TYPES.resp;
  root_compartment_ocid VARCHAR2(512) := '&1';
BEGIN
  -- Send request
  dbms_output.put_line('Send Request');
  resp := DBMS_CLOUD.send_request(
            credential_name => 'OCI_KEY_CRED',
            uri => 'https://identity.region.oraclecloud.com/20160918/compartments?compartmentId=' || root_compartment_ocid,
            method => DBMS_CLOUD.METHOD_GET,
            headers => JSON_OBJECT('opc-request-id' value 'list-compartments')
          );
  dbms_output.put_line('Body: ' || '------------' || CHR(10) || DBMS_CLOUD.get_response_text(resp) || CHR(10));
  dbms_output.put_line('Headers: ' || CHR(10) || '------------' || CHR(10) || DBMS_CLOUD.get_response_headers(resp).to_clob || CHR(10));
  dbms_output.put_line('Status Code: ' || CHR(10) || '------------' || CHR(10) || DBMS_CLOUD.get_response_status_code(resp));
  dbms_output.put_line(CHR(10));
END;

Where: region is an endpoint region. See Identity and Access Management (IAM) API reference in API Reference and Endpoints for more information. For example, where region is: uk-london-1.

Asynchronous Request Example

Shows an example using DBMS_CLOUD.SEND_REQUEST with HTTP POST method to perform the Autonomous Database stop operation and wait for status. This example shows how to use DBMS_CLOUD.SEND_REQUEST with the async_request_url, wait_for_states, and timeout parameters.

--
-- Sent Work Request Autonomous Database Stop Request with Wait for Status
DECLARE
    l_resp DBMS_CLOUD_TYPES.resp;
    l_resp_json JSON_OBJECT_T;
    l_key_shape JSON_OBJECT_T;
    l_body JSON_OBJECT_T;
    status_array DBMS_CLOUD_TYPES.wait_for_states_t;
BEGIN
  status_array := DBMS_CLOUD_TYPES.wait_for_states_t('SUCCEEDED');
  l_body := JSON_OBJECT_T('{}');
  l_body.put('autonomousDatabaseId', 'ocid');
-- Send request
  dbms_output.put_line(l_body.to_clob);
  dbms_output.put_line('Send Request');
  l_resp := DBMS_CLOUD.send_request(
                       credential_name    => 'NATIVE_CRED_OCI',
                       uri                => 'https://database.region.oraclecloud.com/20160918/autonomousDatabases/ocid/actions/stop',
                       method             => DBMS_CLOUD.METHOD_POST,
                       body               => UTL_RAW.cast_to_raw(l_body.to_clob),
                       async_request_url  => 'https://iaas.region.oraclecloud.com/20160918/workRequests',
                       wait_for_states    => status_array,
                       timeout            => 600
                  );
   dbms_output.put_line('resp body: '||DBMS_CLOUD.get_response_text(l_resp));
   dbms_output.put_line('resp headers: '||DBMS_CLOUD.get_response_headers(l_resp).to_clob);
END;
