Using data pump impdp utility we can generate sql or DDL/DML from the dump file using SQLFILE option. When you execute impdp with sqlfile option it won’t import the data into the actual tables or into the schema. Suppose if you wanted to generate some . You can create the karacto.xyz dump file used in this command by running the example provided for the Export FULL parameter. See FULL. > impdp hr/hr DIRECTORY=dpump_dir1 DUMPFILE=karacto.xyz PARFILE=karacto.xyz All data from the karacto.xyz dump file will be loaded except for functions, procedures, packages, and indexes whose names start with emp. Feb 13, · Re: How to do impdp in parallel for multiple dump files? Dean Gagne-Oracle Feb 13, PM (in response to liaison1) If you do a table mode export, you will not get the dependent types, so you would have to make sure the types exist where you are doing the import.
Hello, I am exporting the schema and place the dump file in three different directories At the end,i wanted to load the dump files into another database. Here is the export parfile content. Export is successfully completed. I am using the below parfile content.. But export wrote the dump file on this directory successfully Any help is appreicated Re: Impdp with multiple dump file directories [ message is a reply to message ]. This is a shoot from the hip response where I have not had my 1st cup of coffee this morning.

Can you explain how parallelism works with Data Pump imports using impdp? However, parallelism can be used against a single dmp file by breaking the dmp file into equal-sized chunks and loading each into the target table s simultaneously. However, a Data Pump import is dependent upon other objects, such that they must be done serially, and cannot be parallelized. For example, you cannot parallel load a dependent object before the master objects have been imported.
Consequently the parallel clause for a Data Pump import impdp is most useful when specifying multiple dmp files to be loaded in parallel.
Using the parallel clause against a single dmp file will cause disk contention as multiple Oracle processes attempt to access the same dmp file at the same time, thereby causing disk contention.
