According to Oracle's documentation, the data pump in different ways to export imports, performance can be significantly different, this time just have the opportunity to test, migration table space, direct path, external table, and database chain export, import performance differences. First check that the table space of the source database satisfies the self contained condition: Sql> EXEC Dbms_tts. Transport_set_check (' tjsq,tjsq_tmp ') Pl/sql p

. Dumpfile=temp. DMP:TEMP.DMP is the data pump file you want to import. Reuse_dumpfiles=y: This parameter is removed when imported. Schemas= (bfb2c,trans_user,bfcrm,bfstatuser): The database instance to import, now I just import the first one, so Schemas= (BFB2C) is OK. If the export and import is not the same database, to use the REMAP_SCHEMA=A:B parameter, when you export data from a user, want to import to B users, use this: Remap_schema=a:b. Logfi

For data pump EXPDP/IMPDP, the function is much stronger than the ordinary exp/imp function, so it is difficult to accomplish some common export import tools. For example, the problem that comes up today is to export some tables, but the individual tables only export the structure without exporting the data. Sql> Conn Test/test Connected.

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 compares the differences between IMP and IMPDP import. The comparison of exp and data pump export, you can see that the data pump export speed and direct path, compared to the speed is not the essence
