The Data Pump API, DBMS_DATAPUMP, provides a high-speed mechanism to move all or part of the data and metadata for a site from one database to another. The Data Pump Export and Data Pump Import utilities are based on the Data Pump API.
This chapter provides details about how the Data Pump API works. The following topics are covered:
Examples of Using the Data Pump API
See Also:
Oracle Database PL/SQL Packages and Types Reference for a detailed description of the procedures available in the DBMS_DATAPUMP package
Chapter 1, "Overview of Oracle Data Pump" for additional explanation of Data Pump concepts
The main structure used in the client interface is a job handle, which appears to the caller as an integer. Handles are created using the DBMS_DATAPUMP.OPEN or DBMS_DATAPUMP.ATTACH function. Other sessions can attach to a job to monitor and control its progress. This allows a DBA to start up a job before departing from work and then watch the progress of the job from home. Handles are session specific. The same job can create different handles in different sessions.
There is a state associated with each phase of a job, as follows:
Undefined - before a handle is created
Defining - when the handle is first created
Executing - when the DBMS_DATAPUMP.START_JOB procedure is executed
Completing - when the job has finished its work and the Data Pump processes are ending
Completed - when the job is completed
Stop Pending - when an orderly job shutdown has been requested
Stopping - when the job is stopping
Idling - the period between the time that a DBMS_DATAPUMP.ATTACH is executed to attach to a stopped job and the time that a DBMS_DATAPUMP.START_JOB is executed to restart that job
Not Running - when a master table exists for a job that is not running (has no Data Pump processes associated with it)
Performing DBMS_DATAPUMP.START_JOB on a job in an Idling state will return it to an Executing state.
If all users execute DBMS_DATAPUMP.DETACH to detach from a job in the Defining state, then the job will be totally removed from the database.
When a job abnormally terminates or when an instance running the job is shut down, the job is placed in the Not Running state if it was previously executing or idling. It can then be restarted by the user.
The master control process is active in the Defining, Idling, Executing, Stopping, Stop Pending, and Completing states. It is also active briefly in the Stopped and Completed states. The master table for the job exists in all states except the Undefined state. Worker processes are only active in the Executing and Stop Pending states, and briefly in the Defining state for import jobs.
Detaching while a job is in the Executing state will not halt the job, and you can re-attach to an executing job at any time to resume obtaining status information about the job.
A Detach can occur explicitly, when the DBMS_DATAPUMP.DETACH procedure is executed, or it can occur implicitly when a Data Pump API session is run down, when the Data Pump API is unable to communicate with a Data Pump job, or when the DBMS_DATAPUMP.STOP_JOB procedure is executed.
The Not Running state indicates that a master table exists outside the context of an executing job. This will occur if a job has been stopped (probably to be restarted later) or if a job has abnormally terminated. This state can also be seen momentarily during job state transitions at the beginning of a job, and at the end of a job before the master table is dropped. Note that the Not Running state is shown only in the DBA_DATAPUMP_JOBS view and the USER_DATAPUMP_JOBS view. It is never returned by the GET_STATUS procedure.
Table 6-1 shows the valid job states in which DBMS_DATAPUMP procedures can be executed. The states listed are valid for both export and import jobs, unless otherwise noted.
Table 6-1 Valid Job States in Which DBMS_DATAPUMP Procedures Can Be Executed

Specifies a file for the dump file set, the log file, or the SQLFILE output. |
ATTACH |
Defining, Executing, Idling, Stopped, Completed, Completing, Not Running |
Allows a user session to monitor a job or to restart a stopped job. The attach will fail if the dump file set or master table for the job have been deleted or altered in any way. |

METADATA_FILTER |
Defining |
Restricts metadata processed by a job. |
METADATA_REMAP |

Footnote 1 The ENCRYPTION_PASSWORD parameter can be entered during the Idling state, as well as during the Defining state.
To use the Data Pump API, you use the procedures provided in the DBMS_DATAPUMP package. The following steps list the basic activities involved in using the Data Pump API. The steps are presented in the order in which the activities would generally be performed:
Execute the DBMS_DATAPUMP.OPEN procedure to create a Data Pump job and its infrastructure.
Define any parameters for the job.
Start the job.
Optionally, monitor the job until it completes.
Optionally, detach from the job and reattach at a later time.
Optionally, stop the job.
Optionally, restart the job, if desired.
These concepts are illustrated in the examples provided in the next section.

Oracle Database PL/SQL Packages and Types Reference for a complete description of theDBMS_DATAPUMP packageThis section provides the following examples to help you get started using the Data Pump API:
Example 6-2, "Importing a Dump File and Remapping All Schema Objects"
Example 6-3, "Using Exception Handling During a Simple Schema Export"
The examples are in the form of PL/SQL scripts. If you choose to copy these scripts and run them, then you must first do the following, using SQL*Plus:
Create a directory object and grant READ and WRITE access to it. For example, to create a directory object named dmpdir to which you have access, do the following. Replace user with your username.
SQL> CREATE DIRECTORY dmpdir AS '/rdbms/work';
SQL> GRANT READ, WRITE ON DIRECTORY dmpdir TO user;
Ensure that you have the EXP_FULL_DATABASE and IMP_FULL_DATABASE roles. To see a list of all roles assigned to you within your security domain, do the following:
SQL> SELECT * FROM SESSION_ROLES;
If you do not have the necessary roles assigned to you, then contact your system administrator for help.
Turn on server output if it is not already on. This is done as follows:
SQL> SET SERVEROUTPUT ON
If you do not do this, then you will not see any output to your screen. You must do this in the same session in which you invoke the example. If you exit SQL*Plus, then this setting is lost and must be reset when you begin a new session. (It must also be reset if you connect to a different user name.)
Example 6-1 Performing a Simple Schema Export
The PL/SQL script in this example shows how to use the Data Pump API to perform a simple schema export of the HR schema. It shows how to create a job, start it, and monitor it. Additional information about the example is contained in the comments within the script. To keep the example simple, exceptions from any of the API calls will not be trapped. However, in a production environment, Oracle recommends that you define exception handlers and call GET_STATUS to retrieve more detailed error information when a failure occurs.

Example 6-2 Importing a Dump File and Remapping All Schema Objects
The script in this example imports the dump file created in Example 6-1 (an export of the hr schema). All schema objects are remapped from the hr schema to the blake schema. To keep the example simple, exceptions from any of the API calls will not be trapped. However, in a production environment, Oracle recommends that you define exception handlers and call GET_STATUS to retrieve more detailed error information when a failure occurs.

Example 6-3 Using Exception Handling During a Simple Schema Export
The script in this example shows a simple schema export using the Data Pump API. It extends Example 6-1 to show how to use exception handling to catch the SUCCESS_WITH_INFO case, and how to use the GET_STATUS procedure to retrieve additional information about errors. If you want to get exception information about a DBMS_DATAPUMP.OPEN or DBMS_DATAPUMP.ATTACH failure, then call DBMS_DATAPUMP.GET_STATUS with a DBMS_DATAPUMP.KU$_STATUS_JOB_ERROR information mask and a NULL job handle to retrieve the error details.

Example 6-4 Displaying Dump File Information
The PL/SQL script in this example shows how to use the Data Pump API procedure DBMS_DATAPUMP.GET_DUMPFILE_INFO to display information about a Data Pump dump file outside the context of any Data Pump job. This example displays information contained in the example1.dmp dump file created by the sample PL/SQL script in Example 6-1.
This PL/SQL script can also be used to display information for dump files created by original Export (the exp utility) as well as by the ORACLE_DATAPUMP external tables access driver.
