Oracle learning-dmp file (table) Import and ExportPreface
We still use a lot of dmp files, which are used as the file format for oracle Import and Export tables. Today we will learn how to export and import dmp files.
Dmp File Export
There are generally three types of dmp

6) copy the DMP file from the ASM disk group to the OS directory.

11. What character set the client operating system chooses. I am Chinese, I use Chinese operating system, so I choose ZHS16GBK. The Chinese are advised to choose ZHS16GBK.
12. Client operating system parameter Nls_lang parameters are set. There is only one way to set this up, which is the
Importing and exporting Oracle Data impexp is equivalent to restoring and backing up oracle data. The exp command can export data from a remote server to a local dmp file. The imp command can import the dmp file from the local server to a distant database server. This function can be used to build two identical databases, one for testing and the other for formal use. Execution environment: it can be execute

First, ask the name and size of the tablespace in the target database, create a tablespace in your oracle database, and then use commands to import and export data.Supplement:1. Create a new database;
Importing and exporting Oracle Data imp/exp is equivalent to restoring and backing up oracle data. Exp command
To export data from the remote database server to the local dmp file, the imp command can
To the database server in the distance. This function
DMP version modification tool (C #)
When using oracle to import the dmp file, the following error occurs: "IMP-00010: the exported file is not valid. Title Verification Failed. IMP-00000: Import failed :", now we can use the DMP version modification tool to modify it.
Recently, when I used oracle to import a dmp file
If you want to import Table 1 from Oracle daochu. dmp to imp system/manager @ TEST file = d: \ daochu. dmp tables = (table1), there is no problem. However, there are still many problems that may occur in actual operations. The following describes how to solve the problem.
Appendix 1:
Add data import permissions to users
First, start SQL * puls
Second, log in with system/manager
Third, create user username i
Recently in the use of Oracle import a DMP file, because you do not know how the DMP file is exported, using exp or EXPDP export, so tangled up a relatively long time, finally thought can see the DMP file some auxiliary information, so have this tool.
The following error was reported when using DMP Import
IMP-00010:

After a blue screen appears on the Windows 7 system computer, the system automatically restarts. After the computer is restarted, the system displays information about the blue screen. If you have no time to view the information, you can also go to the "Event Viewer" in Windows 7 (location: Control Panel-system and security-management tools-view event logs ), in the event viewer, you will also see the error system information. The general prompt is as follows:

Oracle Data Import Export IMP/EXP is equivalent to Oracle data restore and backup. The EXP command can export data from a remote database server to a local DMP file, and IMP commands the DMP file to be imported locally into a distant database server. With this feature, you can build two identical databases, one for testing and one for formal use.
Execution environment: can be executed in SQLPLUS.EXE or DOS

As early as the Oracle 8,oracle 8i,oracle 9i, there was no datapump, so the work of the logical database migration depended more on exp/imp,However, when disk space is limited and downtime is short, we usually need a way to do it without landing.At that time, our usual way is to use the pipeline, that is, exp to export the database to the pipe, the target segment through the pipeline directly to the data imp to the target database, so that the data does not fall, eliminating the generation of
Oracle DatabaseModerate timingDmp FileBackup can improve the security and stability of the database and facilitate recovery in the event of a fault. This article describes how to regularly back up the dmp file of an oracle database in SCO Unix. Let's take a look at it.
Prerequisites for backing up dmp files:
1. required information:
Oracle system password and account name and password for backing up data
