46 DBMS_DATAPUMP

The DBMS_DATAPUMP package is used to move all, or part of, a database between databases, including both data and metadata.

See Also:

Oracle Database Utilities for more information on the concepts behind the DBMS_DATAPUMP API, how it works, and how it is implemented in the Data Pump Export and Import utilities

This chapter contains the following topics:


Using DBMS_DATAPUMP

This section contains topics that relate to using the DBMS_DATAPUMP package.


Overview

The support and functionality provided by DBMS_DATAPUMP is as follows:


Security Model

Security for the DBMS_DATAPUMP package is implemented through roles.

Roles

The DATAPUMP_EXP_FULL_DATABASE and DATAPUMP_IMP_FULL_DATABASE roles allow privileged users to take full advantage of the API. The Data Pump API will use these roles to determine whether privileged application roles should be assigned to the processes comprising the job.

DATAPUMP_EXP_FULL_DATABASE

The DATAPUMP_EXP_FULL_DATABASE role affects only Export operations. It allows users running these operations to do the following:

Although the SYS schema does not have the DATAPUMP_EXP_FULL_DATABASE role assigned to it, all security checks performed by Data Pump that require the DATAPUMP_EXP_FULL_DATABASE role will also grant access to the SYS schema.


DATAPUMP_IMP_FULL_DATABASE

The DATAPUMP_IMP_FULL_DATABASE role affects only Import and SQL_FILE operations. It allows users running these operations to do the following:

Although the SYS schema does not have the DATAPUMP_IMP_FULL_DATABASE role assigned to it, all security checks performed by Data Pump that require the DATAPUMP_IMP_FULL_DATABASE role will also grant access to the SYS schema.



Constants

There are several public constants defined for use with the DBMS_DATAPUMP.GET_STATUS procedure. All such constants are defined as part of the DBMS_DATAPUMP package. Any references to these constants must be prefixed by DBMS_DATAPUMP. and followed by the symbols in the following lists:

Mask Bit Definitions

The following mask bit definitions are used for controlling the return of data through the DBMS_DATAPUMP.GET_STATUS procedure.

Dump File Type Definitions

The following definitions are used for identifying types of dump files returned through the DBMS_DATAPUMP.GET_STATUS procedure.


Data Structures

The DBMS_DATAPUMP package defines OBJECT types. The types described in this section are defined in the SYS schema for use by the GET_STATUS function. The way in which these types are defined and used may be different than what you are accustomed to. Be sure to read this section carefully.

The collection of types defined for use with the GET_STATUS procedure are version-specific and include version information in the names of the types. Once introduced, these types will always be provided and supported in future versions of Oracle Database and will not change. However, in future releases of Oracle Database, new versions of these types might be created that provide new or different information. The new versions of these types will have different version information embedded in the type names.

For example, in Oracle Database 10g, release 1 (10.1), there is a sys.ku$_Status1010 type, and in the next Oracle Database release, there could be a sys.ku$_Status1110 type defined. Both types could be used with the GET_STATUS procedure.

Public synonyms have been defined for each of the types used with the GET_STATUS procedure. This makes it easier to use the types and means that you do not have to be concerned with changes to the actual type names or schemas where they reside. Oracle recommends that you use these synonyms whenever possible.

For each of the types, there is a version-specific synonym and a generic synonym. For example, the version-specific synonym ku$_Status1010 is defined for the sys.ku$_Status1010 type.

The generic synonym always describes the latest version of that type. For example, in Oracle Database 10g, release 1, the generic synonym ku$_Status is defined as ku$_Status1010. In a future release, there might be a ku$_Status1110 synonym for sys.ku$Status1110. Because the ku$_Status generic synonym always points to the latest definition, it would now point to ku$_Status1110 rather than to ku$_Status1010.

The choice of whether to use version-specific synonyms or generic synonyms makes a significant difference in how you work. Using version-specific names protects your code from changes in future releases of Oracle Database because those types will continue to exist and be supported. However, access to new information will require code changes to use new synonym names for each of the types. Using the generic names implies that you always want the latest definition of the types and are prepared to deal with changes in different releases of Oracle Database.

When the version of Oracle Database that you are using changes, any C code that accesses types through generic synonym names will need to be recompiled.

Note:

Languages other than PL/SQL must ensure that their type definitions are properly aligned with the version-specific definitions.

Data Structures - Object Types

The DBMS_DATAPUMP package defines the following kinds of OBJECT types:

Worker Status Types

The worker status types describe what each worker process in a job is doing. The schema, object name, and object type of an object being processed will be provided. For workers processing user data, the partition name for a partitioned table (if any), the number of bytes processed in the partition, and the number of rows processed in the partition are also returned. Workers processing metadata provide status on the last object that was processed. No status for idle threads is returned.

The percent_done refers to the amount completed for the current data item being processed. It is not updated for metadata objects.

The worker status types are defined as follows:

CREATE TYPE sys.ku$_WorkerStatus1010 AS OBJECT (
               worker_number      NUMBER,
               process_name       VARCHAR2(30),
               state              VARCHAR2(30),
               schema             VARCHAR2(30),
               name               VARCHAR2(4000),
               object_type        VARCHAR2(200),
               partition          VARCHAR2(30),
               completed_objects  NUMBER,
               total_objects      NUMBER,
               completed_rows     NUMBER,
               completed_bytes    NUMBER,
               percent_done       NUMBER) 
 
CREATE OR REPLACE PUBLIC SYNONYM ku$_WorkerStatus1010
  FOR sys.ku$_WorkerStatus1010;
CREATE TYPE sys.ku$_WorkerStatus1020 AS OBJECT (
               worker_number     NUMBER,        --  Worker process identifier
               process_name      VARCHAR2(30),  --  Worker process name
               state             VARCHAR2(30),  --  Worker process state
               schema            VARCHAR2(30),  --  Schema name
               name              VARCHAR2(4000),--  Object name
               object_type       VARCHAR2(200), --  Object type
               partition         VARCHAR2(30),  --  Partition name
               completed_objects NUMBER,        --  Completed number of objects

               completed_bytes   NUMBER,        --  Number of bytes completed
               percent_done      NUMBER,        --  Percent done current object
               degree            NUMBER         --  Degree of parallelism)
 
CREATE OR REPLACE PUBLIC SYNONYM ku$_WorkerStatus1020
  FOR sys.ku$_WorkerStatus1020;
 
CREATE OR REPLACE PUBLIC SYNONYM ku$_WorkerStatus FOR ku$_WorkerStatus1020;
 
CREATE TYPE sys.ku$_WorkerStatusList1010 AS TABLE OF sys.ku$_WorkerStatus1010

CREATE OR REPLACE PUBLIC SYNONYM ku$_WorkerStatusList1020
  FOR sys.ku$_WorkerStatusList1020;
 
CREATE OR REPLACE PUBLIC SYNONYM ku$_WorkerStatusList
  FOR ku$_WorkerStatusList1020;

Log Entry and Error Types

These types provide informational and error text to attached clients and the log stream. The ku$LogLine.errorNumber type is set to NULL for informational messages but is specified for error messages. Each log entry may contain several lines of text messages.

The log entry and error types are defined as follows:

CREATE TYPE sys.ku$_LogLine1010 AS OBJECT (
               logLineNumber   NUMBER,
               errorNumber     NUMBER,
               LogText         VARCHAR2(2000))
 
CREATE OR REPLACE PUBLIC SYNONYM ku$_LogLine1010 FOR sys.ku$_LogLine1010;
CREATE OR REPLACE PUBLIC SYNONYM ku$_LogLine1020 FOR sys.ku$_LogLine1010;
CREATE OR REPLACE PUBLIC SYNONYM ku$_LogLine FOR ku$_LogLine1010;
CREATE TYPE sys.ku$_LogEntry1010 AS TABLE OF sys.ku$_LogLine1010
 
CREATE OR REPLACE PUBLIC SYNONYM ku$_LogEntry1010 FOR sys.ku$_LogEntry1010;
CREATE OR REPLACE PUBLIC SYNONYM ku$_LogEntry1020 FOR sys.ku$_LogEntry1010;
CREATE OR REPLACE PUBLIC SYNONYM ku$_LogEntry FOR ku$_LogEntry1010;

Job Status Types

The job status type returns status about a job. Usually, the status concerns a running job but it could also be about a stopped job when a client attaches. It is typically requested at attach time, when the client explicitly requests status from interactive mode and every N seconds when the client has requested status periodically.

The job status types are defined as follows (percent_done applies to data only):

CREATE TYPE sys.ku$_DumpFile1010 IS OBJECT (
               file_name          VARCHAR2(4000), -- Fully-qualified name
               file_type          NUMBER,         -- 0=Disk, 1=Pipe, etc.
               file_size          NUMBER,         -- Its length in bytes
               file_bytes_written NUMBER          -- Bytes written so far)

CREATE OR REPLACE PUBLIC SYNONYM ku$_JobStatus FOR ku$_JobStatus1020;

Job Description Types

The job description type holds all the environmental information about the job such as parameter settings and dump file set members. There are a couple of subordinate types required as well.

The job description types are defined as follows:

CREATE TYPE sys.ku$_ParamValue1010 AS OBJECT (
               param_name     VARCHAR2(30),
               param_op       VARCHAR2(30),

CREATE OR REPLACE PUBLIC SYNONYM ku$_JobDesc1020 FOR sys.ku$_JobDesc1020;
CREATE OR REPLACE PUBLIC SYNONYM ku$_JobDesc FOR ku$_JobDesc1020;

Status Types

The status type is an aggregate of some the previous types defined and is the return value for the GET_STATUS call. The mask attribute indicates which types of information are being returned to the caller. It is created by a client's shadow process from information it retrieves off the status queue or directly from the master table.

For errors, the ku$_LogEntry that is returned has already had its log lines ordered for proper output. That is, the original ku$_LogEntry objects have been ordered from outermost context to innermost.

The status types are defined as follows:

CREATE TYPE sys.ku$_Status1010 AS OBJECT
(
mask NUMBER,         /* Indicates which status types are present*/
wip ku$_LogEntry1010,  /* Work-In-Progress: std. exp/imp msgs */
job_description    ku$_JobDesc1010,   /* Complete job description */
job_status         ku$_JobStatus1010, /* Detailed job status + per-worker sts */
error              ku$_LogEntry1010   /* Multi-level contextual errors */
)
CREATE OR REPLACE PUBLIC SYNONYM ku$_Status1010 FOR sys.ku$_Status1010;
 
CREATE TYPE sys.ku$_Status1020 IS OBJECT
        (
               mask             NUMBER,            -- Status types present
               wip              ku$_LogEntry1010,  -- Work in progress
               job_description  ku$_JobDesc1020,   -- Complete job description
               job_status       ku$_JobStatus1020, -- Detailed job status
               error            ku$_LogEntry1010   -- Multi-level context errors
        )
 
CREATE OR REPLACE PUBLIC SYNONYM ku$_Status1020 FOR sys.ku$_Status1020;
 
CREATE OR REPLACE PUBLIC SYNONYM ku$_Status FOR ku$_Status1020;

   filename   IN VARCHAR2,
   directory  IN VARCHAR2,
   filesize   IN VARCHAR2 DEFAULT NULL,
   filetype   IN NUMBER DEFAULT DBMS_DATAPUMP.KU$_FILE_TYPE_DUMP_FILE),
   reusefile  IN NUMBER DEFAULT NULL;

Parameters

Table 46-2 ADD_FILE Procedure Parameters

Parameter Description

handle

The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function.

filename

The name of the file being added. filename must be a simple filename without any directory path information. For dump files, the filename can include a substitution variable, %U, which indicates that multiple files may be generated with the specified filename as a template. The %U is expanded in the resulting file names into a two-character, fixed-width, incrementing integer starting at 01. For example, the dump filename of export%U would cause export01, export02, export03, and so on, to be created depending on how many files are needed to perform the export. For filenames containing the % character, the % must be represented as %% to avoid ambiguity. Any % in a filename must be followed by either a % or a U.

directory

The name of a directory object within the database that is used to locate filename. A directory must be specified. See the Data Pump Export chapter in Oracle Database Utilities for information about the DIRECTORY command-line parameter.

filesize

The size of the dump file that is being added. It may be specified as the number of bytes, number of kilobytes (if followed by K), number of megabytes (if followed by M) or number of gigabytes (if followed by G). An Export operation will write no more than the specified number of bytes to the file. Once the file is full, it will be closed. If there is insufficient space on the device to write the specified number of bytes, the Export operation will fail, but it can be restarted. If not specified, filesize will default to an unlimited size. For Import and SQL_FILE operations, filesize is ignored. The minimum value for filesize is ten times the default Data Pump block size, which is 4 kilobytes. A filesize can only be specified for dump files.

filetype

The type of the file to be added. The legal values are as follows and must be preceded by DBMS_DATAPUMP.:

  • KU$_FILE_TYPE_DUMP_FILE (dump file for a job)

  • KU$_FILE_TYPE_LOG_FILE (log file for a job)

  • KU$_FILE_TYPE_SQL_FILE (output for SQL_FILE job)

reusefile

If 0, a preexisting file will cause an error. If 1, a preexisting file will be overwritten. If NULL, the default action for the file type will be applied (that is, dump files will not be overwritten). This parameter should only be non-NULL for dump files. The reusefile parameter is restricted to export jobs.

Usage Notes


ATTACH Function

This function gains access to a previously-created job.

Syntax

DBMS_DATAPUMP.ATTACH(
   job_name    IN VARCHAR2 DEFAULT NULL,
   job_owner    IN VARCHAR2 DEFAULT NULL) 
 RETURN NUMBER;

Parameters

Table 46-3 ATTACH Function Parameters

Parameter Description

job_name

The name of the job. The default is the job name owned by the user who is specified in the job_owner parameter (assuming that user has only one job in the Defining, Executing, or Idling states).

job_owner

The user who originally started the job. If NULL, the value defaults to the owner of the current session. To specify a job owner other than yourself, you must have either the DATAPUMP_EXP_FULL_DATABASE role (for export operations) or the DATAPUMP_IMP_FULL_DATABASE role (for import and SQL_FILE operations). Being a privileged user allows you to monitor another user's job, but you cannot restart another user's job.


Return Values

An opaque handle for the job. This handle is used as input to the following procedures: ADD_FILE, DATA_FILTER, DETACH, GET_STATUS, LOG_ENTRY, METADATA_FILTER, METADATA_REMAP, METADATA_TRANSFORM, SET_PARALLEL, SET_PARAMETER,START_JOB, STOP_JOB, and WAIT_FOR_JOB.

   name        IN VARCHAR2,
   value       IN CLOB,
   table_name  IN VARCHAR2 DEFAULT NULL,
   schema_name IN VARCHAR2 DEFAULT NULL);

Parameters

Table 46-4 DATA_FILTER Procedure Parameters

Parameter Description

handle

The handle that is returned from the OPEN function

name

The name of the filter

value

The value of the filter

table_name

The name of the table on which the data filter is applied. If no table name is supplied, the filter applies to all tables in the job.

schema_name

The name of the schema that owns the table on which the filter is applied. If no schema name is specified, the filter applies to all schemas in the job. If you supply a schema name you must also supply a table name.


Exceptions

Usage Notes

Table 46-5 Data Filters

Name Datatype Operations that Support Filter Description

INCLUDE_ROWS

NUMBER

EXPORT, IMPORT

If nonzero, this filter specifies that user data for the specified table should be included in the job. The default is 1.

PARTITION_EXPR

PARTITION_LIST

text

EXPORT, IMPORT

For Export jobs, these filters specify which partitions are unloaded from the database. For Import jobs, they specify which table partitions are loaded into the database. Partition names are included in the job if their names satisfy the specified expression (for PARTITION_EXPR) or are included in the list (for PARTITION_LIST). Whereas the expression version of the filter offers more flexibility, the list version provides for full validation of the partition names.

Double quotation marks around partition names are required only if the partition names contain special characters.

PARTITION_EXPR is not supported on jobs across a network link.

Default=All partitions are processed

SAMPLE

NUMBER

EXPORT, IMPORT

For Export jobs, specifies a percentage for sampling the data blocks to be moved. This filter allows subsets of large tables to be extracted for testing purposes.

SUBQUERY

text

EXPORT, IMPORT

Specifies a subquery that is added to the end of the SELECT statement for the table. If you specify a WHERE clause in the subquery, you can restrict the rows that are selected. Specifying an ORDER BY clause orders the rows dumped in the export which improves performance when migrating from heap-organized tables to index-organized tables.



DATA_REMAP Procedure

This procedure specifies transformations to be applied to column data as it is exported from, or imported into, a database.

Syntax

DBMS_DATAPUMP.DATA_REMAP(
   handle          IN NUMBER,
   name            IN VARCHAR2,
   table_name      IN VARCHAR2,
   column          IN VARCHAR2,
   remap_function  IN VARCHAR2),
   schema          IN VARCHAR2 DEFAULT NULL);

Parameters

Table 46-6 DATA_REMAP Procedure Parameters

Parameter Description

handle

The handle of the current job. The current session must have previously attached to the handle through a call to an OPEN function.

name

The name of the remap

table_name

The table containing the column to be remapped

column

The name of the column to be remapped

remap_function

The meaning of remap_function is dependent upon the value of name. See Table 46-7 for a list of possible names.

schema

The schema containing the column to be remapped. If NULL, the remapping applies to all schemas moved in the job that contain the specified table.


Exceptions

Usage Notes

Note:

If the called function uses package state variables, then to ensure that remapping is performed consistently across all tables, the job should be run with a SET_PARALLEL value of 1 and no restart operations should be performed.

The Data Remap functions are listed in Table 46-7.

Table 46-7 Names of Data Remap Functions

Name Meaning of remap_function Meaning

COLUMN_FUNCTION

String having the format:

[schema.]package.function

The name parameter references a PL/SQL package function which is called to modify the data for the specified column. The function accepts a single parameter, which has the same datatype as the remapped column, and returns a value having the same datatype as the remapped column. Note that the default for the schema is the schema of the user performing the export.



DETACH Procedure

This procedure specifies that the user has no further interest in using the handle.

Syntax

DBMS_DATAPUMP.DETACH(
   handle  IN NUMBER);

Parameters

Table 46-8 DETACH Procedure Parameters

Parameter Description

handle

The handle of the job. The current session must have previously attached to the handle through a call to either an OPEN or ATTACH function.

Usage Notes


GET_DUMPFILE_INFO Procedure

This procedure retrieves information about a specified dump file.

Syntax

DBMS_DATAPUMP.GET_DUMPFILE_INFO(
   filename    IN VARCHAR2,
   directory   IN VARCHAR2,
   info_table  OUT ku$_dumpfile_info,
   filetype    OUT NUMBER);

Parameters

Table 46-9 GET_DUMPFILE_INFO Procedure Parameters

Parameter Description

filename

A simple filename with no directory path information

directory

A directory object that specifies where the file can be found

info_table

A PL/SQL table for storing information about the dump file

filetype

The type of file (Data Pump dump file, original Export dump file, or unknown)


Exceptions

The GET_DUMPFILE_INFO procedure is a utility routine that operates outside the context of any Data Pump job. Exceptions are handled differently for this procedure than for procedures associated in some way with a Data Pump job. A full exception stack should be available directly, without the need to call the GET_STATUS procedure to retrieve the detailed information. The exception for this procedure is as follows:

Usage Notes

You can use the GET_DUMPFILE_INFO procedure to request information about a specific file. If the file is not recognized as any type of dump file, then a filetype of zero will be returned and the dump file info_table will remain empty.

A filetype value of one indicates a Data Pump dump file. A file type value of two indicates an original Export dump file. In both cases, the dump file info_table will be populated with information retrieved from the dump file header. Rows of this table consist of item code and value pairs, where the item code indicates the type of information and the value column is a VARCHAR2 containing the actual data (converted to a string in some cases). The table is defined as follows:

CREATE TYPE sys.ku$_dumpfile_item IS OBJECT (
                item_code       NUMBER,           -- Identifies header item
                value           VARCHAR2(2048)    -- Text string value)/
 
GRANT EXECUTE ON sys.ku$_dumpfile_item TO PUBLIC; 
CREATE OR REPLACE PUBLIC SYNONYM ku$_dumpfile_item FOR sys.ku$_dumpfile_item;
 
CREATE TYPE sys.ku$_dumpfile_info AS TABLE OF sys.ku$_dumpfile_item/
 
GRANT EXECUTE ON sys.ku$_dumpfile_info TO PUBLIC; 
CREATE OR REPLACE PUBLIC SYNONYM ku$_dumpfile_info FOR sys.ku$_dumpfile_info;
 

The item codes, which can easily be extended to provide more information as needed, are currently defined as follows (prepended with the package name, DBMS_DATAPUMP.):

KU$_DFHDR_FILE_VERSION         CONSTANT NUMBER := 1;
KU$_DFHDR_MASTER_PRESENT       CONSTANT NUMBER := 2;
KU$_DFHDR_GUID                 CONSTANT NUMBER := 3;

GET_STATUS Procedure

This procedure monitors the status of a job or waits for the completion of a job.

Syntax

DBMS_DATAPUMP.GET_STATUS(
   handle    IN NUMBER,
   mask      IN BINARY_INTEGER,
   timeout   IN NUMBER DEFAULT NULL,
   job_state OUT VARCHAR2,
   status    OUT ku$_Status1010);

Parameters

Table 46-10 GET_STATUS Procedure Parameters

Parameter Description

handle

The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function. A null handle can be used to retrieve error information after OPEN and ATTACH failures.

mask

A bit mask that indicates which of four types of information to return:

  • KU$_STATUS_WIP

  • KU$_STATUS_JOB_DESC

  • KU$_STATUS_JOB_STATUS

  • KU$_STATUS_JOB_ERROR

Each status has a numerical value. You can request multiple types of information by adding together different combinations of values. See Data Structures - Object Types.

timeout

Maximum number of seconds to wait before returning to the user. A value of 0 requests an immediate return. A value of -1 requests an infinite wait. If KU$_STATUS_WIP or KU$_STATUS_JOB_ERROR information is requested and becomes available during the timeout period, then the procedure returns before the timeout period is over.

job_state

Current state of the job. If only the job state is needed, it is much more efficient to use this parameter than to retrieve the full ku$_Status structure.

status

A ku$_Status is returned. The ku$_Status mask indicates what kind of information is included. This could be none if only KU$_STATUS_WIP or KU$_STATUS_JOB_ERROR information is requested and the timeout period expires. This can be a ku$_Status1010 or ku$_Status1020 object type.


Exceptions

Usage Notes

The GET_STATUS procedure is used to monitor the progress of an ongoing job and to receive error notification. You can request various type of information using the mask parameter. The KU$_STATUS_JOB_DESC and KU$_STATUS_JOB_STATUS values are classified as synchronous information because the information resides in the master table. The KU$_STATUS_WIP and KU$_STATUS_JOB_ERROR values are classified as asynchronous because the messages that embody these types of information can be generated at any time by various layers in the Data Pump architecture.

Error Handling

There are two types of error scenarios that need to be handled using the GET_STATUS procedure:

After a job has begun, a client's main processing loop will typically consist of a call to GET_STATUS with an infinite timeout (-1) "listening" for KU$_STATUS_WIP and KU$_STATUS_JOB_ERROR messages. If status was requested, then JOB_STATUS information will also be in the request.

When the ku$_Status is interpreted, the following guidelines should be used:


LOG_ENTRY Procedure

This procedure inserts a message into the log file.

Syntax

DBMS_DATAPUMP.LOG_ENTRY(
   handle         IN NUMBER,
   message        IN VARCHAR2
   log_file_only  IN NUMBER DEFAULT 0);

Parameters

Table 46-11 LOG_ENTRY Procedure Parameters

Parameter Description

handle

The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function.

message

A text line to be added to the log file

log_file_only

Specified text should be written only to the log file. It should not be returned in GET_STATUS work-in-progress (KU$_STATUS_WIP) messages.


Exceptions

Usage Notes

The message is added to the log file. If log_file_only is zero (the default), the message is also broadcast as a KU$_STATUS_WIP message through the GET_STATUS procedure to all users attached to the job.

The LOG_ENTRY procedure allows applications to tailor the log stream to match the abstractions provided by the application. For example, the command-line interface supports INCLUDE and EXCLUDE parameters defined by the user. Identifying these values as calls to the underlying METADATA_FILTER procedure would be confusing to users. Instead, the command-line interface can enter text into the log describing the settings for the INCLUDE and EXCLUDE parameters.

Lines entered in the log stream from LOG_ENTRY are prefixed by the string, ";;; "


METADATA_FILTER Procedure

This procedure provides filters that allow you to restrict the items that are included in a job.

Syntax

DBMS_DATAPUMP.METADATA_FILTER(
   handle       IN NUMBER,
   name         IN VARCHAR2,
   value        IN VARCHAR2,
   object_path  IN VARCHAR2 DEFAULT NULL);

DBMS_DATAPUMP.METADATA_FILTER(
   handle       IN NUMBER,
   name         IN VARCHAR2,
   value        IN CLOB,
   object_path  IN VARCHAR2 DEFAULT NULL);

Parameters

Table 46-12 METADATA_FILTER Procedure Parameters

Parameter Description

handle

The handle returned from the OPEN function

name

The name of the filter. See Table 46-13 for descriptions of the available filters.

value

The value of the filter

object_path

The object path to which the filter applies. If the default is used, the filter applies to all applicable objects. Lists of the object paths supported for each mode are contained in the catalog views for DATABASE_EXPORT_OBJECTS, SCHEMA_EXPORT_OBJECTS, and TABLE_EXPORT_OBJECTS. (Note that the TABLE_EXPORT_OBJECTS view is applicable to both Table and Tablespace mode because their object paths are the same.)

For an import operation, object paths reference the mode used to create the dump file rather than the mode being used for the import.


Table 46-13 describes the name, the object type, and the meaning of the filters available with the METADATA_FILTER procedure. The datatype for all the filters is a text expression. All operations support all filters.

Table 46-13 Filters Provided by METADATA_FILTER Procedure

Name Object Type Meaning

NAME_EXPR

NAME_LIST

Named objects

Defines which object names are included in the job. You use the object type parameter to limit the filter to a particular object type.

For Table mode, identifies which tables are to be processed.

SCHEMA_EXPR

SCHEMA_LIST

Schema objects

Restricts the job to objects whose owning schema name is satisfied by the expression.

For Table mode, only a single SCHEMA_EXPR filter is supported. If specified, it must only specify a single schema (for example, 'IN (''SCOTT'')').

For Schema mode, identifies which users are to be processed.

TABLESPACE_EXPR

TABLESPACE_LIST

TABLE, CLUSTER, INDEX, ROLLBACK_SEGMENT

Restricts the job to objects stored in a tablespace whose name is satisfied by the expression.

For Tablespace mode, identifies which tablespaces are to be processed. If a partition of an object is stored in the tablespace, the entire object is added to the job.

For Transportable mode, identifies which tablespaces are to be processed. If a table has a single partition in the tablespace set, all partitions must be in the tablespace set. An index is not included within the tablespace set unless all of its partitions are in the tablespace set. A domain index is not included in the tablespace set unless all of its secondary objects are included in the tablespace set.

INCLUDE_PATH_EXPR

INCLUDE_PATH_LIST

EXCLUDE_PATH_EXPR

EXCLUDE_PATH_LIST

All

Defines which object paths are included in, or excluded from, the job. You use these filters to select only certain object types from the database or dump file set. Objects of paths satisfying the condition are included (INCLUDE_PATH_*) or excluded (EXCLUDE_PATH_*) from the operation. The object_path parameter is not supported for these filters.


Exceptions

Usage Notes


METADATA_REMAP Procedure

This procedure specifies a remapping to be applied to objects as they are processed in the specified job.

Syntax

DBMS_DATAPUMP.METADATA_REMAP (
   handle      IN NUMBER,
   name        IN VARCHAR2,
   old_value   IN VARCHAR2,
   value       IN VARCHAR2,
   object_type IN VARCHAR2 DEFAULT NULL);

Parameters

Table 46-14 METADATA_REMAP Procedure Parameters

Parameter Description

handle

The handle for the current job. The current session must have previously attached to the handle through a call to the OPEN function.

name

The name of the remap. See Table 46-15 for descriptions of the available remaps.

old_value

Specifies which value in the dump file set should be reset to value

value

The value of the parameter for the remap. This signifies the new value that old_value should be translated into.

object_type

Designates the object type to which the remap applies. The list of object types supported for each mode are contained in the DATABASE_EXPORT_OBJECTS, SCHEMA_EXPORT_OBJECTS, TABLE_EXPORT_OBJECTS, and TABLESPACE_EXPORT_OBJECTS catalog views.

By default, the remap applies to all applicable objects within the job. The object_type parameter allows a caller to specify different parameters for different object types within a job. Remaps that explicitly specify an object type override remaps that apply to all object types.


Table 46-15 describes the remaps provided by the METADATA_REMAP procedure.

Table 46-15 Remaps Provided by the METADATA_REMAP Procedure

Name Datatype Object Type Meaning

REMAP_SCHEMA

Text

Schema objects

Any schema object in the job that matches the object_type parameter and was located in the old_value schema will be moved to the value schema.

Privileged users can perform unrestricted schema remaps.

Nonprivileged users can perform schema remaps only if their schema is the target schema of the remap.

For example, SCOTT can remap his BLAKE's objects to SCOTT, but SCOTT cannot remap SCOTT's objects to BLAKE.

REMAP_TABLESPACE

Text

TABLE, INDEX, ROLLBACK_SEGMENT, MATERIALIZED_VIEW, MATERIALIZED_VIEW_LOG,TABLE_SPACE

Any storage segment in the job that matches the object_type parameter and was located in the old_value tablespace will be relocated to the value tablespace.

REMAP_DATAFILE

Text

LIBRARY, TABLESPACE, DIRECTORY

Any datafile reference in the job that matches the object_type parameter and referenced the old_value datafile will be redefined to use the value datafile.

REMAP_TABLE

Text

TABLE

Any reference to a table in the job that matches the old_value table name will be replaced with the value table name. The old_value parameter may refer to a partition such as employees.low. This allows names for tables constructed the by PARTITION_OPTIONS=DEPARTITION parameter to be specified by the user.

METADATA_TRANSFORM Procedure

This procedure specifies transformations to be applied to objects as they are processed in the specified job.

Syntax

DBMS_DATAPUMP.METADATA_TRANSFORM (
   handle      IN NUMBER,
   name        IN VARCHAR2,
   value       IN VARCHAR2,
   object_type IN VARCHAR2 DEFAULT NULL);

   name        IN VARCHAR2,
   value       IN NUMBER,
   object_type IN VARCHAR2 DEFAULT NULL);

Parameters

Table 46-16 METADATA_TRANSFORM Procedure Parameters

Parameter Description

handle

The handle for the current job. The current session must have previously attached to the handle through a call to the OPEN function.

name

The name of the transformation. See Table 46-17 for descriptions of the available transforms.

value

The value of the parameter for the transform

object_type

Designates the object type to which the transform applies. The list of object types supported for each mode are contained in the DATABASE_EXPORT_OBJECTS, SCHEMA_EXPORT_OBJECTS, TABLE_EXPORT_OBJECTS, and TABLESPACE_EXPORT_OBJECTS catalog views.

By default, the transform applies to all applicable objects within the job. The object_type parameter allows a caller to specify different transform parameters for different object types within a job. Transforms that explicitly specify an object type override transforms that apply to all object types.


Table 46-17 describes the transforms provided by the METADATA_TRANSFORM procedure.

Table 46-17 Transforms Provided by the METADATA_TRANFORM Procedure

Name Datatype Object Type Meaning

PCTSPACE

NUMBER

TABLE

INDEX

TABLESPACE

Specifies a percentage multiplier used to alter extent allocations and datafile sizes. Used to shrink large tablespaces for testing purposes.

Defaults to 100.

SEGMENT_ATTRIBUTES

NUMBER

TABLE, INDEX

If nonzero (TRUE), emit storage segment parameters.

Defaults to 1.

STORAGE

NUMBER

TABLE

If nonzero (TRUE), emit storage clause. (Ignored if SEGMENT_ATTRIBUTES is zero.)

Defaults to nonzero (TRUE).

OID

NUMBER

TYPE

TABLE

If zero, inhibits the assignment of the exported OID during type or table creation. Instead, a new OID will be assigned.

Use of this transform on Object Tables will cause breakage in REF columns that point to the table.

Defaults to 1.

SEGMENT_CREATION

NUMBER

TABLE

If nonzero (TRUE), the SQL SEGMENT CREATION clause is added to the CREATE TABLE statement. That is, the CREATE TABLE statement will explicitly say either SEGMENT CREATION DEFERRED or SEGMENT CREATION IMMEDIATE.

If the value is FALSE, then the SEGMENT CREATION clause is omitted from the CREATE TABLE statement. Set this parameter to FALSE to use the default segment creation attributes for the table(s) being loaded.

Defaults to nonzero (TRUE).

(This functionality is available starting with Oracle Database 11g Release 2 (11.2.0.2).)

Usage Notes


OPEN Function

This function is used to declare a new job using the Data Pump API. The handle that is returned is used as a parameter for calls to all other procedures (but not to the ATTACH function).

Syntax

DBMS_DATAPUMP.OPEN (
   operation    IN VARCHAR2,
   mode         IN VARCHAR2,
   remote_link  IN VARCHAR2 DEFAULT NULL,
   job_name     IN VARCHAR2 DEFAULT NULL,
   version      IN VARCHAR2 DEFAULT 'COMPATIBLE'
 RETURN NUMBER;

Parameters

Table 46-18 OPEN Function Parameters

Parameter Meaning

operation

The type of operation to be performed. Table 46-19 contains descriptions of valid operation types.

mode

The scope of the operation to be performed. Table 46-20 contains descriptions of valid modes. Specifying NULL generates an error.

remote_link

If the value of this parameter is non-null, it provides the name of a database link to the remote database that will be the source of data and metadata for the current job.

job_name

The name of the job. The name is limited to 30 characters; it will be truncated if more than 30 characters are used. It may consist of printable characters and spaces. It is implicitly qualified by the schema of the user executing the OPEN function and must be unique to that schema (that is, there cannot be other Data Pump jobs using the same name).

The name is used to identify the job both within the API and with other database components such as identifying the job in the DBA_RESUMABLE view if the job becomes suspended through lack of resources. If no name is supplied, a system generated name will be provided for the job in the following format: "SYS_<OPERATION>_<MODE>_%N".

The default job name is formed where %N expands to a two-digit incrementing integer starting at '01' (for example, "SYS_IMPORT_FULL_03"). The name supplied for the job will also be used to name the master table and other resources associated with the job.

version

The version of database objects to be extracted. This option is only valid for Export, network Import, and SQL_FILE operations. Database objects or attributes that are incompatible with the version will not be extracted. Legal values for this parameter are as follows:

  • COMPATIBLE - (default) the version of the metadata corresponds to the database compatibility level and the compatibility release level for feature (as given in the V$COMPATIBILITY view). Database compatibility must be set to 9.2 or higher.

  • LATEST - the version of the metadata corresponds to the database version.

  • A specific database version, for example, '10.0.0'. In Oracle Database10g, this value cannot be lower than 10.0.0.


Table 46-19 describes the valid operation types for the OPEN function.

Table 46-19 Valid Operation Types for the OPEN Function

Operation Description

EXPORT

Saves data and metadata to a dump file set or obtains an estimate of the size of the data for an operation.

IMPORT

Restores data and metadata from a dump file set or across a database link.

SQL_FILE

Displays the metadata within a dump file set, or from across a network link, as a SQL script. The location of the SQL script is specified through the ADD_FILE procedure.


Table 46-20 describes the valid modes for the OPEN function.

Table 46-20 Valid Modes for the OPEN Function

Mode Description

FULL

Operates on the full database or full dump file set except for the SYS, XDB,ORDSYS, MDSYS, CTXSYS, ORDPLUGINS, and LBACSYS schemas.

SCHEMA

Operates on a set of selected schemas. Defaults to the schema of the current user. All objects in the selected schemas are processed. Users cannot specify SYS, XDB, ORDSYS, MDSYS, CTXSYS, ORDPLUGINS, or LBACSYS schemas for this mode.

TABLE

Operates on a set of selected tables. Defaults to all of the tables in the current user's schema. Only tables and their dependent objects are processed.

TABLESPACE

Operates on a set of selected tablespaces. No defaulting is performed. Tables that have storage in the specified tablespaces are processed in the same manner as in Table mode.

TRANSPORTABLE

Operates on metadata for tables (and their dependent objects) within a set of selected tablespaces to perform a transportable tablespace export/import.

A bitmask to supply special options for processing the job. The possible values are as follows:

  • KU$_DATAOPT_SKIP_CONST_ERR

  • KU$_DATAOPT_XMLTYPE_CLOB

  • KU$_DATAOPT_DISABL_APPEND_HINT

Export supports the value KU$_DATAOPT_XMLTYPE_CLOB. This option stores compressed XMLType columns in the dump file as CLOBs rather than as XML documents.

Import supports the value KU$_DATAOPT_SKIP_CONST_ERR. This option specifies that if constraint violations occur while data is being imported into user tables, the rows that cause the violations will be rejected and the load will continue. If this option is not set, a constraint error will abort the loading of the entire partition (or table for unpartitioned tables). Setting this option may affect performance, especially for pre-existing tables with unique indexes or constraints.

Import also supports the value KU$_DATAOPT_DISABL_APPEND_HINT. This option prevents the append hint from being applied to the data load. Disabling the APPEND hint can be useful if there is a small set of data objects to load that already exist in the database and some other application may be concurrently accessing one or more of the data objects.

Use of this parameter requires that the version on the OPEN function be set to 11.1 or later.

Default=0

ENCRYPTION

Text

Export

Specifies what to encrypt in the dump file set, as follows:

ALL enables encryption for all data and metadata in the export operation.

DATA_ONLY specifies that only data is written to the dump file set in encrypted format.

ENCRYPTED_COLUMNS_ONLY specifies that only encrypted columns are written to the dump file set in encrypted format.

METADATA_ONLY specifies that only metadata is written to the dump file set in encrypted format.

NONE specifies that no data is written to the dump file set in encrypted format.

This parameter requires a job version of 11.1 or later.

The default value depends upon the combination of encryption-related parameters that are used. To enable encryption, either ENCRYPTION or ENCRYPTION_PASSWORD or both, must be specified. If only ENCRYPTION_PASSWORD is specified, then ENCRYPTION defaults to ALL. If neither ENCRYPTION nor ENCRYPTION_PASSWORD is specified, then ENCRYPTION defaults to NONE.

To specify ALL, DATA_ONLY, or METADATA_ONLY, the COMPATIBLE initialization parameter must be set to at least 11.1.

NOTE: If the data being exported includes SecureFiles that you want to be encrypted, then you must specify ENCRYPTION=ALL to encrypt the entire dump file set. Encryption of the entire dump file set is the only way to achieve encryption security for SecureFiles during a Data Pump export operation.

ENCRYPTION_ALGORITHM

Text

Export

Identifies which cryptographic algorithm should be used to perform encryption. Possible values are AES128, AES192, and AES256.

The ENCRYPTION_ALGORITHM parameter requires that you also specify either ENCRYPTION or ENCRYPTION_PASSWORD; otherwise an error is returned. See Oracle Database Advanced Security Administrator's Guide for information about encryption algorithms.

This parameter requires a job version of 11.1 or later.

Default=AES128

ENCRYPTION_MODE

Text

Export

Identifies the types of security used for encryption and decryption. The values are as follows:

PASSWORD requires that you provide a password when creating encrypted dump file sets. You will need to provide the same password when you import the dump file set. PASSWORD mode requires that you also specify the ENCRYPTION_PASSWORD parameter. The PASSWORD mode is best suited for cases in which the dump file set will be imported into a different or remote database, but which must remain secure in transit.

TRANSPARENT allows an encrypted dump file set to be created without any intervention from a database administrator (DBA), provided the required Oracle Encryption Wallet is available. Therefore, the ENCRYPTION_PASSWORD parameter is not required, and will in fact, cause an error if it is used in TRANSPARENT mode. This encryption mode is best suited for cases in which the dump file set will be imported into the same database from which it was exported.

DUAL creates a dump file set that can later be imported using either the Oracle Encryption Wallet or the password that was specified with the ENCRYPTION_PASSWORD parameter. DUAL mode is best suited for cases in which the dump file set will be imported on-site using the Oracle Encryption Wallet, but which may also need to be imported offsite where the Oracle Encryption Wallet is not available.

When you use the ENCRYPTION_MODE parameter, you must also use either the ENCRYPTION or ENCRYPTION_PASSWORD parameter. Otherwise, an error is returned.

To use DUAL or TRANSPARENT mode, the COMPATIBLE initialization parameter must be set to at least 11.1.

The default mode depends on which other encryption-related parameters are used. If only ENCRYPTION is specified, then the default mode is TRANSPARENT. If ENCRYPTION_PASSWORD is specified and the Oracle Encryption Wallet is open, then the default is DUAL. If ENCRYPTION_PASSWORD is specified and the Oracle Encryption Wallet is closed, then the default is PASSWORD.

ENCRYPTION_PASSWORD

Text

Export and Import

Specifies a key for re-encrypting encrypted table columns, metadata, or table data so that they are not written as clear text in the dump file set. If the export operation involves encrypted table columns, but an encryption password is not supplied, then the encrypted columns will be written to the dump file set as clear text and a warning will be issued.

NOTE: Data Pump encryption functionality has changed as of Oracle Database 11g release 1 (11.1). Prior to release 11.1, the ENCRYPTION_PASSWORD parameter applied only to encrypted columns. However, as of release 11.1, the new ENCRYPTION parameter provides options for encrypting other types of data. This means that if you now specify ENCRYPTION_PASSWORD without also specifying ENCRYPTION and a specific option, then all data written to the dump file will be encrypted (equivalent to specifying ENCRYPTION=ALL). If you want to re-encrypt only encrypted columns, you must now specify ENCRYPTION=ENCRYPTED_COLUMNS_ONLY in addition to ENCRYPTION_PASSWORD.

For export operations, this parameter is required if ENCRYPTION_MODE is set to either PASSWORD or DUAL.

If ENCRYPTION_PASSWORD is specified but ENCRYPTION_MODE is not specified, then it is not necessary to have Transparent Data Encryption set up since ENCRYPTION_MODE will default to PASSWORD.

The ENCRYPTION_PASSWORD parameter is not valid if the requested encryption mode is TRANSPARENT.

To use the ENCRYPTION_PASSWORD parameter if ENCRYPTION_MODE is set to DUAL, you must have Transparent Data Encryption set up. See Oracle Database Advanced Security Administrator's Guide for more information about Transparent Data Encryption.

For network exports, the ENCRYPTION_PASSWORD parameter in conjunction with ENCRYPTION=ENCRYPTED_COLUMNS_ONLY is not supported with user-defined external tables that have encrypted columns. The table will be skipped and an error message will be displayed, but the job will continue.

Encryption attributes for all columns must match between the exported table definition and the target table.

This parameter requires a job version of 10.2 or later.

ESTIMATE

Text

Export and Import

Specifies that the estimate method for the size of the tables should be performed before starting the job.

If BLOCKS, a size estimate for the user tables is calculated using the count of blocks allocated to the user tables.

If STATISTICS, a size estimate for the user tables is calculated using the statistics associated with each table. If no statistics are available for a table, the size of the table is estimated using BLOCKS.

The ESTIMATE parameter cannot be used in Transportable Tablespace mode.

Default=BLOCKS

ESTIMATE_ONLY

Number

Export

Specifies that only the estimation portion of an export job should be performed. This option is useful for estimating the size of dump files when the size of the export is unknown.

FLASHBACK_SCN

NUMBER

Export and network Import

System change number (SCN) to serve as transactionally consistent point for reading user data. If neither FLASHBACK_SCN nor FLASHBACK_TIME is specified, there will be no transactional consistency between partitions, except for logical standby databases and Streams targets. FLASHBACK_SCN is not supported in Transportable mode.

FLASHBACK_TIME

Text

Export and network Import

Either the date and time used to determine a consistent point for reading user data or a string of the form TO_TIMESTAMP(...).

If neither FLASHBACK_SCN nor FLASHBACK_TIME is specified, there will be no transactional consistency between partitions.

FLASHBACK_SCN and FLASHBACK_TIME cannot both be specified for the same job. FLASHBACK_TIME is not supported in Transportable mode.

INCLUDE_METADATA

NUMBER

Export and Import

If nonzero, metadata for objects will be moved in addition to user table data.

If zero, metadata for objects will not moved. This parameter converts an Export operation into an unload of user data and an Import operation into a load of user data.

INCLUDE_METADATA is not supported in Transportable mode.

Default=1

PARTITION_OPTIONS

Text

Import

Specifies how partitioned tables should be handled during an import operation. The options are as follows:

NONE means that partitioning is reproduced on the target database as it existed in the source database.

DEPARTITION means that each partition or subpartition that contains storage in the job is reproduced as a separate unpartitioned table. Intermediate partitions that are subpartitioned are not re-created (although their subpartitions are converted into tables). The names of the resulting tables are system-generated from the original table names and partition names unless the name is overridden by the REMAP_TABLE metadata transform.

MERGE means that each partitioned table is re-created in the target database as an unpartitioned table. The data from all of the source partitions is merged into a single storage segment. This option is not supported for transportable jobs or when the TRANSPORTABLE parameter is set to ALWAYS.

This parameter requires a job version of 11.1 or later.

Default=NONE

SKIP_UNUSABLE_INDEXES

NUMBER

Import

If nonzero, rows will be inserted into tables having unusable indexes. SKIP_UNUSABLE_INDEXES is not supported in Transportable mode.

Default=1

SOURCE_EDITION

Text

Export and network Import

The application edition that will be used for determining the objects that will be unloaded for export and for network import.

TABLE_EXISTS_ACTION

Text

Import

Specifies the action to be performed when data is loaded into a preexisting table. The possible actions are: TRUNCATE, REPLACE, APPEND, and SKIP.

If INCLUDE_METADATA=0, only TRUNCATE and APPEND are supported.

If TRUNCATE, rows are removed from a preexisting table before inserting rows from the Import.

Note that if TRUNCATE is specified on tables referenced by foreign key constraints, the TRUNCATE will be modified into a REPLACE.

If REPLACE, preexisting tables are replaced with new definitions. Before creating the new table, the old table is dropped.

If APPEND, new rows are added to the existing rows in the table.

If SKIP, the preexisting table is left unchanged.

TABLE_EXISTS_ACTION is not supported in Transportable mode.

The default is SKIP if metadata is included in the import. The default is APPEND if INCLUDE_METADATA is set to 0.

TABLESPACE_DATAFILE

Text

Import

Specifies the full file specification for a datafile in the transportable tablespace set. TABLESPACE_DATAFILE is only valid for transportable mode imports.

TABLESPACE_DATAFILE can be specified multiple times, but the value specified for each occurrence must be different.

TARGET_EDITION

Text

Import

The application edition that will be used for determining where the objects will be loaded for import and for network import.

TRANSPORTABLE

Text

Export

For export operations done in table mode, allows the data to be moved using transportable tablespaces. Storage segments in the moved tablespaces that are not associated with the parent schemas (tables) will be reclaimed at import time. If individual partitions are selected in a table-mode job, only the tablespaces referenced by those partitions will be moved. During import, the moved partitions can only be reconstituted as tables by using the PARTITION_OPTIONS=DEPARTITION parameter.

Use of the TRANSPORTABLE parameter prohibits the subsequent import of the dump file into a database at a lower version or using different character sets. Additionally, the data files may need to be converted if the target database is on a different platform. The TRANSPORTABLE parameter is not allowed if a network link is supplied on the OPEN call.

The possible values for this parameter are as follows:

ALWAYS - data is always moved by moving data files

NEVER - data files are never used for copying user data

This parameter requires a job version of 11.1 or later

Default=NEVER

TTS_FULL_CHECK

NUMBER

Export

If nonzero, verifies that a transportable tablespace set has no dependencies (specifically, IN pointers) on objects outside the set, and vice versa. Only valid for Transportable mode Exports.

Default=0

USER_METADATA

NUMBER

Export and network Import

For schema-mode operations, specifies that the metadata to re-create the users' schemas (for example, privilege grants to the exported schemas) should also be part of the operation if set to nonzero. Users must be privileged to explicitly set this parameter.

The USER_METADATA parameter cannot be used in Table, Tablespace, or Transportable Tablespace mode.

Default=1 if user has DATAPUMP_EXP_FULL_DATABASE role; 0 otherwise.

Usage Notes


START_JOB Procedure

This procedure begins or resumes execution of a job.

Syntax

DBMS_DATAPUMP.START_JOB (
   handle       IN NUMBER,
   skip_current    IN  NUMBER DEFAULT 0,
   abort_step      IN  NUMBER DEFAULT 0,
   cluster_ok      IN  NUMBER DEFAULT 1,
   service_name    IN  VARCHAR2 DEFAULT NULL);

Parameters

Table 46-24 START_JOB Procedure Parameters

Parameter Description

handle

The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function.

skip_current

If nonzero, causes actions that were 'in progress' on a previous execution of the job to be skipped when the job restarts. The skip will only be honored for Import jobs. This mechanism allows the user to skip actions that trigger fatal bugs and cause the premature termination of a job. Multiple actions can be skipped on a restart. The log file will identify which actions are skipped. If a domain index was being processed, all pieces of the domain index are skipped even if the error occurred in only a subcomponent of the domain index.

A description of the actions skipped is entered into the log file. skip_current is ignored for the initial START_JOB in a job.

If zero, no data or metadata is lost upon a restart.

abort_step

Value must be 0. Inserting values other than 0 into this argument will have unintended consequences.

cluster_ok

If = 0, all workers are started on the current instance. Otherwise, workers are started on instances usable by the job.

service_name

If specified, indicates a service name used to constrain the job to specific instances or to a specific resource group.


Exceptions

Usage Notes


STOP_JOB Procedure

This procedure terminates a job, but optionally, preserves the state of the job.

Syntax

DBMS_DATAPUMP.STOP_JOB (
   handle      IN NUMBER,
   immediate   IN NUMBER DEFAULT 0,
   keep_master IN NUMBER DEFAULT NULL,
   delay       IN NUMBER DEFAULT 60);

Parameters

Table 46-25 STOP_JOB Procedure Parameters

Parameter Description

handle

The handle of a job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function. At the end of the procedure, the user is detached from the handle.

immediate

If nonzero, the worker processes are aborted immediately. This halts the job quickly, but parts of the job will have to be rerun if the job is ever restarted.

If zero, the worker processes are allowed to complete their current work item (either metadata or table data) before they are terminated. The job is placed in a Stop Pending state while the workers finish their current work.

keep_master

If nonzero, the master table is retained when the job is stopped. If zero, the master table is dropped when the job is stopped. If the master table is dropped, the job will not be restartable. If the master table is dropped during an export job, the created dump files are deleted.

delay

The number of seconds to wait until other attached sessions are forcibly detached. The delay allows other sessions attached to the job to be notified that a stop has been performed. The job keeps running until either all clients have detached or the delay has been satisfied. If no delay is specified, then the default delay is 60 seconds. If a shorter delay is used, clients might not be able to retrieve the final messages for the job through the GET_STATUS procedure.


Exceptions

Usage Notes


WAIT_FOR_JOB Procedure

This procedure runs a job until it either completes normally or stops for some other reason.

Syntax

DBMS_DATAPUMP.WAIT_FOR_JOB (
  handle      IN   NUMBER,
  job_state   OUT  VARCHAR2);

Parameters

Table 46-26 WAIT_FOR_JOB Procedure Parameters

Parameter Description

handle

The handle of the job. The current session must have previously attached to the handle through a call to either the OPEN or ATTACH function. At the end of the procedure, the user is detached from the handle.

job_state

The state of the job when it has stopped executing. This will be either Stopped or Completed.


Exceptions

Usage Notes

This procedure provides the simplest mechanism for waiting for the completion of a Data Pump job. The job should be started before calling WAIT_FOR_JOB. When WAIT_FOR_JOB returns, the job will no longer be executing. If the job completed normally, the final status will be Completed. If the job stopped executing because of a STOP_JOB request or an internal error, the final status will be Stopped.
