tablespace in the tablespace or its index is moved, an error message is displayed. when it is set to N, the export function only checks single-ended dependencies. If the index's tablespace is moved but the table's tablespace is not moved, the error message is displayed. If the table's tablespace is moved, if the tablespace where the index is not moved, no error message is displayed. 26. TRANSPORT_TABLESPACESSpecify the execution tablespace mode for export 27.

The data pump is a server tool, and the exported files are stored on the server where the database is located. Of course, we know that the files can be controlled through directory objects. The directory object has four levels by default. Of course, there is a priority order. The priority is from top to bottom 1. specify a specific directory for each file. when expdp is exported, the specified DIRECTORY parameter 3. the directory specified by the user

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.

. 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.
