Oracle 11g database expdp / impdp full amount of import and export

 

From one user to another user to export import

problem

Environment: oracle 11g; redhat 6

usera is a DBA privileges, password usera

The total amount of export everything under usera users, and imported to the newly created user userb

solve

Creating Directory: create or replace directory DUMP_DIR_D as '/home/oracle/rhuser/oracledmp';

1, before retesting to restore the environment

DROP USER userb cascade;
drop tablespace tbsfsj including contents and datafiles;

2, create a table space and user empowerment and

create TABLESPACE tbsfsj DATAFILE '/home/oracle/rhuser/tbsfsj.dbf'  -- redhat user size 10M autoextend on maxsize 30G; create user userb identified by userb default tablespace tbsfsj; -- grant connect, resource, DATAPUMP_IMP_FULL_DATABASE, DATAPUMP_EXP_FULL_DATABASE -- to userb; GRANT dba to userb; grant read, write on directory DUMP_DIR_D to userb;

3, schemas way to export

expdp usera/usera directory=DUMP_DIR_D dumpfile=exp1.dmp logfile=exp1.log schemas=usera

4, schemas by importing

impdp userb/userb schemas=usera directory=DUMP_DIR_D dumpfile=imp1.dmp logfile=imp1.log remap_schema=usera:userb

What Is Data Pump Export?

Data Pump Export (hereinafter referred to as Export for ease of reading) is a utility for unloading data and metadata into a set of operating system files called a dump file set. The dump file set can be imported only by the Data Pump Import utility. The dump file set can be imported on the same system or it can be moved to another system and loaded there.

The dump file set is made up of one or more disk files that contain table data, database object metadata, and control information. The files are written in a proprietary, binary format. During an import operation, the Data Pump Import utility uses these files to locate each database object in the dump file set.

Because the dump files are written by the server, rather than by the client, the database administrator (DBA) must create directory objects that define the server locations to which files are written. See "Default Locations for Dump, Log, and SQL Files" for more information about directory objects.

Data Pump Export enables you to specify that a job should move a subset of the data and metadata, as determined by the export mode. This is done using data filters and metadata filters, which are specified through Export parameters. See "Filtering During Export Operations".

To see some examples of the various ways in which you can use Data Pump Export, refer to "Examples of Using Data Pump Export".

Export provides different modes for unloading different portions of the database. The mode is specified on the command line, using the appropriate parameter. The available modes are described in the following sections:

• "Full Export Mode"
• "Schema Mode"
• "Table Mode"
• "Tablespace Mode"
• "Transportable Tablespace Mode"

The mode is specified on the command line, using the appropriate parameter. The available modes are described in the following sections:

• "Full Import Mode"
• "Schema Mode"
• "Table Mode"
• "Tablespace Mode"
• "Transportable Tablespace Mode"
