1. Instructions on using expdp/impdp on the client Some documents about Oracle expdp/impdp commands have been prepared. The links are as follows: Comparison between exp/IMP and expdp/impdp and some optimization items in use Http://blog.csdn.net/tianlesoftware/article/details/6093973 Oracle 10g Data Pump expdp/impdp H

An example of oracle impdp and expdp is provided. Create a test table and insert Test Data Create table test_tab (id number not null primary key, name varchar2 (20); insert into test_tab values (1, 'Data 1 '); Create directory object create or replace directory DMP_DIR as '/oradata/ebankbak/'; Export the specified table expdp mia/mia tables=test_tab dumpfile=test.dmp directory=DMP_DIR Import the specified

The original version of a testing database of the company is Oracle 11gR2. Some of the 10g syntax is somewhat different. The boss said to re-build the test database and use the 10G version. Although it can be shut down, the data volume is not big, but during the day, R D colleagues need to use the test library, so they can only work overtime at night. We plan to use the data pump expdp/impdp. Since the version parameter needs to be added to the impor

Two problems encountered during impdp import: impdp import encountered two problems Two days ago, you need to import the data dump exported from a remote test database using expdp to a local test environment. Some problems are encountered, which is worth a summary. Environment Introduction: 1. Data volume: 10 + tables, 2. Both the source and target databases are 11.2.0.4 3. Different character sets, the s

follows: Extimate_only={y | N When set to Y, the export action estimates only the disk space occupied by the object, and does not perform an export job, when n, not only estimating the disk space occupied by the object, but also performing an export operation, examples are as follows: EXPDP Scott/tiger estimate_only=y Nologfile=y 7. EXCLUDE This option specifies the object type or related object to exclude when performing an action. The syntax is as follows: exclude=object_type[:name_clause][,.

Use IMPDP to export server dump files locally, use IMPDP to import remote database users locally1) EXPDP is a 2 of the dump files that can be generated on the client) IMPDP is a migration copy of the data that can be performed between different instances 1:1) The remote database WSJB user is exported to the local disk by using the EXPDP command under the D:\ Micr

An example of using expdp is as follows: Expdp qlzq/qlzqp SCHEMAS = ebmall directory = test dumpfile = ebmall. dmp logfile = ebmall. log This is an operation to export all objects under the user's ebmall to the ebmall. dmp file under the test directory.

Problems and Solutions of impdp ORA-39002, ORA-39166 and ORA-39164 During performance tests on imp and impdp, we found that if the table contains a lob field, loading is really slow, and there are about 1000 entries per second. At this speed, basically, you don't need to work. For example, 50000000/1000 million records, 60/60/13.89 = hours, the time is unacceptab

1. Use expdp and impdp Oracle Database 10 Gb introduces the latest data pump technology, the role of Data Pump Export Import (expdp and impdp) 1) implement logical backup and logical recovery.2) move objects between database users.3) move objects between databases4) Implement table space migration. Ii. Differences between data pump export and traditional export Before 10 Gb, the traditional export and impor

. For example: EXPDP user/pwd parfile=xxx.par Logfile=a.log, if logfile is also specified in the parameter file, the logfile in the command line will prevail; for example: EXPDP user/pwd logfile= A.log Parfile=xxx.par, and this, will take precedence in the parameter file, because Parfile=xxx.par is written at the back of the command line.3.
