我将如何从转储文件创建数据库？我的系统上没有具有相同结构的现有数据库，因此它必须包含作业、事件、表等。

我将转储和日志文件放在 E: 驱动器中

我已经尝试过导入实用程序

E:/>impdp system/tiger@oratest FILE=WB_PROD_FULL_20MAY11.dmp

但我收到错误

invalid argument value
bad dump file specification
unable to open dump file "E:\app\admin\oratest\dpdump\WB_PROD_F
ULL_20MAY11.dmp" for read
unable to open file
unable to open file
(OS 2) The system cannot find the file specified.

当我在 Windows 资源管理器中看到 DMP 文件（取自 Linux 服务器）显示为崩溃转储文件

我不明白如何解决这个问题。请帮我解决这个问题。

我是甲骨文的新手...

How was the database exported?

  • If it was exported using exp and a full schema was exported, then

    1. Create the user:

      create user <username> identified by <password> default tablespace <tablespacename> quota unlimited on <tablespacename>;

    2. Grant the rights:

      grant connect, create session, imp_full_database to <username>;

    3. Start the import with imp:

      imp <username>/<password>@<hostname> file=<filename>.dmp log=<filename>.log full=y;

  • If it was exported using expdp, then start the import with impdp:

    impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;

Looking at the error log, it seems you have not specified the directory, so Oracle tries to find the dmp file in the default directory (i.e., E:\app\Vensi\admin\oratest\dpdump\).

Either move the export file to the above path or create a directory object to pointing to the path where the dmp file is present and pass the object name to the impdp command above.

所有这些代码都放入 *.bat 文件并立即运行：

我在 oracle 中创建用户的代码。crate_drop_user.sql 文件

drop user "USER" cascade;
DROP TABLESPACE "USER";

CREATE TABLESPACE USER DATAFILE 'D:\ORA_DATA\ORA10\USER.ORA' SIZE 10M REUSE 
    AUTOEXTEND 
    ON NEXT  5M  EXTENT MANAGEMENT LOCAL 
    SEGMENT SPACE MANAGEMENT  AUTO
/ 

CREATE  TEMPORARY TABLESPACE "USER_TEMP" TEMPFILE 
    'D:\ORA_DATA\ORA10\USER_TEMP.ORA' SIZE 10M REUSE AUTOEXTEND
    ON NEXT  5M  EXTENT MANAGEMENT LOCAL 
    UNIFORM SIZE 1M    
/

CREATE USER "USER"  PROFILE "DEFAULT" 
    IDENTIFIED BY "user_password" DEFAULT TABLESPACE "USER" 
    TEMPORARY TABLESPACE "USER_TEMP" 
/    

alter user USER quota unlimited on "USER";

GRANT CREATE PROCEDURE TO "USER";
GRANT CREATE PUBLIC SYNONYM TO "USER";
GRANT CREATE SEQUENCE TO "USER";
GRANT CREATE SNAPSHOT TO "USER";
GRANT CREATE SYNONYM TO "USER";
GRANT CREATE TABLE TO "USER";
GRANT CREATE TRIGGER TO "USER";
GRANT CREATE VIEW TO "USER";
GRANT "CONNECT" TO "USER";
GRANT SELECT ANY DICTIONARY to "USER";
GRANT CREATE TYPE TO "USER";

创建文件 import.bat 并将以下行放入其中：

SQLPLUS SYSTEM/systempassword@ORA_alias @"crate_drop_user.SQL"
IMP SYSTEM/systempassword@ORA_alias FILE=user.DMP FROMUSER=user TOUSER=user GRANTS=Y log =user.log

如果您将从一个用户导入到另一个用户，请小心。例如，如果您有名为 user1 的用户，并且您将导入到 user2，您可能会丢失所有授权，因此您必须重新创建它。

祝你好运，伊万

如果您使用来自@sathyajith-bhat 响应的impdp命令示例：

impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;

您将需要使用强制参数目录并创建并授予它：

CREATE OR REPLACE DIRECTORY DMP_DIR AS 'c:\Users\USER\Downloads';
GRANT READ, WRITE ON DIRECTORY DMP_DIR TO {USER};

或使用定义之一：

select * from DBA_DIRECTORIES;

我的 ORACLE Express 11g R2 具有默认名称DATA_PUMP_DIR（位于 {inst_dir}\app\oracle/admin/xe/dpdump/），您仍然需要为您的用户授予它。
