How to import an Oracle database from dmp file and log file?

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.


All this peace of code put into *.bat file and run all at once:

My code for creating user in oracle. crate_drop_user.sql file

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";

create file import.bat and put this lines in it:

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

Be carefull if you will import from one user to another. For example if you have user named user1 and you will import to user2 you may lost all grants , so you have to recreate it.

Good luck, Ivan
