Oracle Database Export Import

The requirement is to export the data in database A to a *.dmp file, and then import the *.dmp file into database B.
1. Export database A in the cmd window, enter the following command:

Export all databases

EXP User name/password @ database name File=d:\*.dmp full=y

Export the database under the current user
EXP username/Password @ database name owner= (username) file=d:\*.dmp

    2. Connecting to database b 
    under SQL Plus enter the following command:     Conn Sys/sys as S YSDBA;
    3. Create user
    create user username identified by password; 
&n Bsp   4. Grant User DBA Authority
    grant connect,resource,dba to user name;
    5. Import Database A            Enter the following command under CMD:
   &NBSP ; Import entire library to a user
    IMP username/password @ database name full=y file=d:\*.dmp ignore=y 
     Import a table to user
&N Bsp   IMP username/password @ database name file=d:\*.dmp tables= (table name)          To this end, the Oracle database Export import completed, I hope that the deployment will be completed tomorrow.
