first, what is WinDbg? What can it do? WinDbg is a powerful user-state and kernel-State debugging tool under the Windows platform. It can easily navigate to the root of the problem through the DMP file, can be used to analyze the blue screen, program crashes (ie crash) reasons, is an essential tool in our daily work, learn to use it, will effectively improve our problem solving efficiency and accuracy rate. 　　Third, set the symbol table: The symbo

; American _ America. al32utf8 From the composition of nls_lang, we can see that the real impact on the database character set is actually the third part. Therefore, if the character set between the two databases is the same as that in the third part, data can be imported and exported to each other. The preceding information is only prompted in Chinese or English. 2. view database character sets This involves three character sets, The first is the character set of the kernel El server; The secon

Use of exp/imp Export Import Tool 1. Export tool exp 1. It is the directory for storing the next executable file in the operating system/ORACLE_HOME/bin The exp export tool compresses data backup in the database into a binary system file, which can be migrated between different operating systems.It has three modes:A. User Mode: export data of all user objects and objects;B. Table mode: export all or specified tables of the user;C. entire database: export all objects in the database. 2. Example o

I. Basic commands 1. Get help $ Exp help = y $ Imp help = y 2. Three ways of working (1) Interactive Mode $ Exp // enter the required parameters as prompted (2) Command Line $ Exp user/pwd @ dbname file =/oracle/test. dmp full = y // enter the required parameters in the command line. (3) parameter file Method $ Exp parfile = username. par // enter the required parameters in the parameter file Parameter file username. par content userid = username/user

Precautions when using expdp and impdp: Exp and IMP are client toolsProgramThey can be used either on the client or on the server. Expdp and impdp are tool programs on the server. They can only be used on the Oracle server, but not on the client. IMP only applies to exp exported files, not expdp exported files; impdp only applies to expdp exported files, not exp exported files. When you run the expdp or impdp command, you can leave the username/password @ Instance name as the identity, a

original table. The recommended naming method is the current date of the original table name, which makes it more readable.

When importing data from IMP in Oracle, hybriddb for MySQL prompts that the character set is inconsistent. The imp import and exp export functions of Oracle are often used in the production environment for data migration. The character set is usually queried in the source database and target database, The following error message is displayed when importing IMP in the test environment: The import command is as follows: [Oracle@localhost.localdomain:/soft] $ imp scott/scott file =/soft/scott_v1.

1. Backup: 1.1. Create a database_exp.bat batch file First, create the DMP and log files for seven days, and then create a batch file for exporting the database. This script can back up the database for the last seven days, as shown in database_ext.bat: Del F: \ mydata_mytest \ oradata7.dmpDel F: \ mydata_mytest \ oradata7.logRen F: \ mydata_mytest \ oradata6.dmp oradata7.dmpRen F: \ mydata_mytest \ orad

Importing and exporting Oracle Data imp/exp is equivalent to restoring and backing up oracle data. The exp command can export data from the remote database server to the local dmp file, and the imp command can import the dmp file from the local to the distant database server. This function can be used to build two identical databases, one for testing and the other for formal use. Execution Environment: In S

Oracle Import and Export Command Parsing This article introduces the import and export of Oracle Data IMP and exp commands, and describes the corresponding parameters. Drills to deepen understanding.At last, the article discusses the problems that may occur when using these two commands (such as insufficient permissions and different Oracle versions), and puts forward corresponding solutions;The content in this article is excerpted from the Internet.
