Data Pump Import (invoked with the impdp command) is a new utility as of Oracle This parameter is valid only in the Enterprise Edition of Oracle Database 10g. . expdp SYSTEM/password SCHEMAS=hr DIRECTORY=dpump_dir1. Either run IMP once OR export the 10 schemas to 10 separate files, and imp the 10 2) yes, that is what it is programmed to do (impdp – datapump – is more. For example, if one database is Oracle Database 12c, then the other database must be 12c, 11g, or 10g. Note that Data Pump checks only the major version.

Regarding 4 each time you run IMP, it reads the dmp file from start to finish.

Purpose Tells Import what to do if the table it is trying to create already exists. Data Filters Data filters specify restrictions on the rows that are to be imported.

Does that work in 10g? In interactive-command mode, the current exprp continues running, but logging to the terminal is stopped and the Import prompt is displayed. As with the dump file set, the log file is relative to the server and not the client.

Since my system tablespace is a locally managed one i’m unable to create a dictionary manged tablespace.

Migrating Data Using Oracle Data Pump

The log file, schemas. I have my source oracle database 11g rel If you are using the Data Pump API, the restriction on attaching to only one job at a time does not apply.

Specifies the default location in which the import job can find the dump file set and where it should create log and SQL files. An understanding of how Data Pump allocates and handles these files will help you to use Export and Import to their fullest advantage.


In general, Oracle recommends that you place such statements in a parameter file because escape characters are not necessary in parameter files. Encryption attributes for all columns must match between the exported table definition and the target table. This question is Whilst you are here, check out some content from the AskTom team: The import job looks for the exp1. Data Pump will not load tables with disabled unique indexes.

Enables you to specify the Import parameters directly on the command line. In general however, Data Pump import cannot read dump file sets created by an Oracle release that is newer than the current release unless the VERSION parameter is explicitly specified.


OIDs are no longer used for type validation. Imppd import operation is performed with data that is consistent as of this SCN. However, some tasks that were incomplete at the time of shutdown may have to be redone at restart time. Assume the following is in a parameter file, exclude.

Enables you to filter the metadata that is imported by specifying objects and object types that you want to exclude from the import job.

Although its functionality and its parameters are similar to those of the original Import utility impthey are completely separate utilities and their files are not compatible. Export and import nonschema-based objects such as tablespace and schema definitions, epdp privilege grants, resource plans, and so forth.


If the source database is read-only, then the user on the source database must have a locally-managed tablespace assigned as a default temporary tablespace. In transportable tablespace mode, the metadata from a transportable tablespace export dump file set or from another database is loaded.

In some cases, because of feature redesign, the original Import parameter is no longer needed so there is no Data Pump command to compare it to. Any existing file that has a name matching the one specified with this parameter is overwritten. Similarly, the Oracle database requires permission from the orac,e system to read and write files in the directories.

Exporting and Importing Between Different Database Releases

When the import source is a dump file set, the amount of data to be loaded is already known, so the percentage complete is automatically calculated. If a job stops before it starts running that is, it is in the Defining statethe master table is dropped. I would get the following error if I use 11g client to export, one internet post suggests to use 12 client and export was successful: You can create the expfull.

The same filter name can be specified multiple times within a job. The query must be enclosed in single or double quotation marks.

Database compatibility must be set to 9. It seems it is trying to creat tablespaces in the same location as the source database.
