performing the import. suggest a cold backup be used. If an object is excluded, all of its dependent objects are also excluded.The TABLE_EXISTS_ACTION=REPLACE parameter tells Import to drop the table if it already exists and to then re-create and load it using the dump file contents. As a result, Data Pump imports only rows for customers whose credit limit is greater than $10,000. (See PARALLEL.)
Metadata filtering is implemented through the EXCLUDE and INCLUDE parameters. toid_novalidate Specifies whether or not type validation The following is an example of using the import SOURCE_EDITION parameter: This example assumes the existence of an edition named exp_edition on the system from which objects are being imported. Therefore, the directory object must point to shared storage that is accessible by all instances of the Oracle RAC. The following is an example of using the STREAMS_CONFIGURATION parameter. See FULL.
The FLASHBACK_TIME parameter pertains only to the flashback query capability of Oracle Database. They should not be executed directly. You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. Be sure to read the following sections before using the Import parameters: Use of Quotation Marks On the Data Pump Command Line.
If SOURCE_EDITION=name is specified, the objects from that edition are imported. full The entire export file is imported. Proper use of these backup/recovery tools allows the DBA to recover The Multiple REMAP_TABLESPACE parameters can be specified, but no two can have the same source tablespace. The only exception to this is if TRANSPORTABLE=ALWAYS is also specified, in which case single or multiple partitions of a specified table can be imported. The following are examples of how case-sensitivity can be preserved in the different Import modes. an error must be fixed. Use the IMP tool from oracle: Imp parfile = import.par. Displays online help for the Import utility. provides a complete copy of altered structures since the last full or built. LinuxMonitoringRemote supportRemote If no value is entered or if the default value of 0 is used, no additional information is displayed beyond information about the completion of each object type, table, or partition. strive to update our BC Oracle support information. When you start an import operation and specify a connect identifier, the local Import client connects to the database instance identified by the connect identifier, retrieves data from that database instance, and writes it to that database instance. For the given mode of import, all the objects contained within the source, and all their dependent objects, are included except those specified in an EXCLUDE statement. In transportable tablespace mode, the metadata from a transportable tablespace export dump file set or from another database is loaded. column_name -- the column whose data is to be remapped. * (Import only) imports full tables; it can?t Data Pump Import can only remap tablespaces for transportable imports in databases where the compatibility level is set to 10.1 or later. be used to do a conditional load. The following is an example of using the SCHEMAS parameter. partitions can also be specified. while the import is active: If SKIP_CONSTRAINT_ERRORS is not set, then the default behavior is to roll back the entire load of the data object on which non-deferred constraint violations are encountered. Oracle is the registered trademark of Oracle Corporation. Oracle Utilities: The Definitive Reference". The query_clause is typically a SQL WHERE clause for fine-grained row selection, but could be any SQL clause. is the registered trademark of Oracle Corporation. For Streams and other Oracle database options, anonymous PL/SQL blocks may appear within the SQLFILE output. The source_datafile and target_datafile names should be exactly as you want them to appear in the SQL statements where they are referenced. Cause: The address specified is not valid, or the program being connected to does not exist. creation statements. However, this prevents the writing of the log file. Imports and exports extract or insert an Only object types in the source (and their dependents) that are explicitly specified in the INCLUDE statement are imported. Many of the descriptions include an example of how to use the parameter. Finally, test to see whether the server process is dead and whether a trace file was generated at failure time. This mode is enabled by pressing Ctrl+C during an import operation started with the command-line interface or the parameter file interface. RECALCULATE always generates new and open_versions > 0; If the QUERY parameter includes references to another table with columns whose names match the table being loaded, and if those columns are used in the query, then you will need to use a table alias to distinguish between columns in the table being loaded and columns in the SELECT statement with the same name. Starts the current job to which you are attached. ForumClass metadata will be imported from the export file. The Import ESTIMATE parameter is valid only if the NETWORK_LINK parameter is also specified. should occur on import. Enables you to alter object creation DDL for objects being imported.
publisher Note that in this situation, an import mode of FULL is specified. after import for the same reason.
If no mode is specified, then Import attempts to load the entire dump file set in the mode in which the export operation was run. The datafile_name must include an absolute directory path specification (not a directory object name) that is valid on the system where the target database resides. A table-mode import is specified using the TABLES parameter. The NETWORK_LINK parameter is simply being used as part of the example. Enables you to filter what is loaded during the import operation. In the following example, the dashes (--) indicate that a comment follows, and the hr schema name is shown, but not the password. That is, the log file must be written to a disk file, and not written into the Oracle ASM storage.
Assume the following is in a parameter file, imp_include.par, being used by a DBA or some other user with the DATAPUMP_IMP_FULL_DATABASE role: You can then issue the following command: You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. transport_tablespace [N] When Y, transportable tablespace The following example shows the use of the TRANSPORTABLE parameter during a network link import. For a complete description of the commands available in interactive-command mode, see Commands Available in Import's Interactive-Command Mode. This means that the following EXCLUDE statements will be interpreted as follows: EXCLUDE=CONSTRAINT will exclude all nonreferential constraints, except for NOT NULL constraints and any constraints needed for successful table creation and loading. The same filter name can be specified multiple times within a job. Interactive-command mode is also enabled when you attach to an executing or stopped job. A directory object specified on the DUMPFILE, LOGFILE, or SQLFILE parameter overrides any directory object that you specify for the DIRECTORY parameter. Different schemas to separate development and production environments can coexist in the same database. In full import mode, the entire content of the source (dump file set or another database) is loaded into the target database. See FULL. Metadata Filters for an example of using filtering. Stops the import client session, exits Import, and discontinues logging to the terminal, but leaves the current job running. The following is an example of using the TRANSPORT_DATAFILES parameter. (For a real-time status of the job, use the STATUS command in interactive mode.). The following is an example of using the NOLOGFILE parameter. Server If the file_name you specify already exists, it will be overwritten. Unless specifically noted, these parameters can also be specified in a parameter file. To perform an orderly shutdown, use STOP_JOB (without any associated value). for use in parallel or shared instances. The export file contains objects in the following order: Integrity constraints, views, procedures, and triggers. The job version must be set to 11.2 or higher. Under Oracle7, the user must be granted the the date and time the export was taken. This is the default. Otherwise, the job will fail. You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. The optional name clause must be separated from the object type with a colon and enclosed in double quotation marks, because single quotation marks are required to delimit the name strings. This is not a valid option if the CONTENT parameter is set to DATA_ONLY. Specifies whether to suppress the default behavior of creating a log file. Create directory name as Physical_Path_of_directory; Grant read, write on directory name to nomUser; Kill the session: Alter system kill session ','. Table 3-2 lists the activities you can perform for the current job from the Data Pump Import prompt in interactive-command mode. All rights reserved. compile [Y] Tells import to compile procedural objects as Example 3-2 Performing a Schema-Mode Import. and %t add the sequence and redo thread numbers to the format. SAFE will import the To perform an immediate shutdown, specify STOP_JOB=IMMEDIATE. Because EXIT_CLIENT leaves the job running, you can attach to the job at a later time if it is still executing or in a stopped state. buffer Specifies the size, in bytes, of the buffer used to
You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. The object_type is optional. See DUMPFILE. If this parameter is not specified, then the default edition on the target database is used, even if an edition was specified in the export job. A tablespace-mode import is specified using the TABLESPACES parameter. The following example assumes that the sh.sales table has been exported into a dump file named sales.dmp. See NETWORK_LINK. The PARFILE parameter cannot be specified within a parameter file. During the following import situations, Data Pump automatically creates the tablespaces into which the data will be imported: The import is being done in FULL or TRANSPORT_TABLESPACES mode, The import is being done in table mode with TRANSPORTABLE=ALWAYS. The default is y.
If this parameter is specified as y, the existing datafiles are reinitialized. Filtering can restrict what is imported using this import mode (see Filtering During Import Operations). The only exception is the PARFILE parameter because parameter files cannot be nested. Using Directory Objects When Oracle Automatic Storage Management Is Enabled for information about Oracle Automatic Storage Management and directory objects. The examples assume that the hr schema has been granted these roles. This example results in an import of the employees table (excluding constraints) from the source database. If you supply a value for integer, it specifies how frequently, in seconds, job status should be displayed in logging mode. Oracle recommends that you place this parameter in a parameter file, which can reduce the number of escape characters that might otherwise be needed on the command line. current off-line and on-line redo logs can be recovered. feedback. For every parameter you enter, you must enter an equal sign (=) and a value. The following is an example of using the LOGFILE parameter. In this example, a DIRECTORY parameter is not provided. The EMP table is exported without the EMPNO column being encrypted, but before importing the table you enable encryption on the EMPNO column. The resulting CREATE TABLE statement for the employees table would then look similar to the following. DATA_ONLY loads only table row data into existing tables; no database objects are created. Suppose that, as user SYSTEM, you execute the following Export and Import commands to remap the hr schema into the scott schema: In this example, if user scott already exists before the import, then the Import REMAP_SCHEMA command will add objects from the hr schema into the existing scott schema. The DATA_OPTIONS parameter provides options for how to handle certain types of data during exports and imports. SAP Business Objects Financial Consolidation uses a single Oracle account to store all its database objects and to manage all its connections to the Oracle server. To see which objects can be filtered, you can query the following views: DATABASE_EXPORT_OBJECTS for Full-mode imports, SCHEMA_EXPORT_OBJECTS for schema-mode imports, and TABLE_EXPORT_OBJECTS for table-mode and tablespace-mode imports. The following considerations apply when you are using these options: When you use TRUNCATE or REPLACE, ensure that rows in the affected tables are not targets of any referential constraints. All rights reserved. The only types of database links supported by Data Pump Import are: public, fixed-user, and connected-user. The datatypes of the source argument and the returned value should both match the datatype of the designated column in the table.
Metadata filtering is implemented through the EXCLUDE and INCLUDE parameters. toid_novalidate Specifies whether or not type validation The following is an example of using the import SOURCE_EDITION parameter: This example assumes the existence of an edition named exp_edition on the system from which objects are being imported.
