How do I import a .dmp file into Oracle?

Presuming you have a .dmp file created by oracle exp then

imp help=y

will be your friend. It will lead you to

imp file=<file>.dmp show=y

to see the contents of the dump and then something like

imp scott/tiger@example file=<file>.dmp fromuser=<source> touser=<dest>

to import from one user to another. Be prepared for a long haul though if it is a complicated schema as you will need to precreate all referenced schema users, and tablespaces to make the imp work correctly

I am Using Oracle Database Express Edition 11g Release 2.

Follow the Steps:

Open run SQl Command Line

Step 1: Login as system user

       SQL> connect system/tiger

Step 2 : SQL> CREATE USER UserName IDENTIFIED BY Password;

Step 3 : SQL> grant dba to UserName ;

Step 4 : SQL> GRANT UNLIMITED TABLESPACE TO UserName;

Step 5:

        SQL> CREATE BIGFILE TABLESPACE TSD_UserName             DATAFILE 'tbs_perm_03.dat'             SIZE 8G             AUTOEXTEND ON;

Open Command Prompt in Windows or Terminal in Ubuntu. Then Type:

Note : if you Use Ubuntu then replace " \" to " /" in path.

Step 6: C:\> imp UserName/password@localhost file=D:\abc\xyz.dmp log=D:\abc\abc_1.log full=y;

Done....

I hope you Find Right solution here.

Thanks.

i got solution what you are getting as per imp help=y it is mentioned that imp is only valid for TRANSPORT_TABLESPACE as below:

So, Please create table space for your user:

CREATE TABLESPACE <tablespace name> DATAFILE <path to save, example: 'C:\ORACLEXE\APP\ORACLE\ORADATA\XE\ABC.dbf'> SIZE 100M AUTOEXTEND ON NEXT 100M MAXSIZE 10G EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;
