impdp example

When you use impdp, you will find that many Parameter options are different from imp. For example, you cannot find the fromuser and touser parameters, you cannot find the ignore parameters, and parameters such as indexes no longer exist.Of course, these functions are still available and more powerful. impdp has many new substitution parameters.The following three

We often use the exp/imp command for import and export, which is indeed convenient, but also limited. For example, the tablespace names to be imported and exported must be the same, and the schema names must be the same. Recently I encountered such a problem. In this case, the Data Pump Import and Export tools such as expdp and impdp play a role. Space name of the table and index to be exported: SQL> sele

Some time ago in a migration of data pump and exp, found that the difference in efficiency is quite large. Here is an example of a simple comparison. This article describes ways to improve the efficiency of IMPDP import. The test in the previous article found that IMPDP's import speed is comparable to IMP's import speed. When Oracle introduced the data pump, it was mentioned that IMPDP's import speed was 1

You can access user objects under different instances on different servers through the databse link, for example: SEL

databases. The utility can be called using the following command: Example: impdp scott/tiger DIRECTORY = dmpdir DUMPFILE = scott. dmp You can control how the import runs. The specific method is to enter various parameters after the 'impdp 'command. To specify parameters, use the Keyword: Format: impdp KEY

Summary In the normal storage and database migration, when encountering a large database when using exp often takes a few hours, time consuming. oracle10g later can use EXPDP to export the database to spend much less time than Exp spent, and the file is much smaller.Ii. difference between Exp/imp and EXPDP/

Import Mode As with the export mode, the following 5 modes are mutually exclusive. Full mode Set Full=yes, if there is no datapump_imp_full_database role, can only be imported into the data under their own schema Schema schema Sets the schema parameter, which is the following syntax Schemas=schema_name [,...] The following example imports HR data into the HR schema > IMPDP hr schemas=hr directory=dpu

Exclude and include parameters can filter or filter specific objects or object types when using EXPDP or IMPDP. For example, to export a particular table or not to export a specific tables, views, and stored procedures, indexes, constraints, authorization statistics, and so on. The following methods and examples are given for EXPDP or IMPDP using exclude and incl
