1)optional but recommended: open SQL Developer and create a new Table space for the new(import) schema from the SYS User (SYSDBA Role)
CREATE TABLESPACE PTS_DW_TS DATAFILE '/u01/app/oracle/oradata/orcl12c/orcl/pts_dw_ts.dbf' SIZE 100M AUTOEXTEND ON MAXSIZE unlimited;
2) create a new User similar to the User for which the Database export has been created
create user PTS_DW identified by Admin123 default tablespace PTS_DW_TS quota unlimited on PTS_DW_TS;
3) grant privileges to the new User
grant connect, create session, imp_full_database to PTS_DW ;
4) open a terminal and navigate to the imp utility directory and invoke the utility
cd /u01/app/oracle/product/12.1.0.2/db_1/bin
imp PTS_DW/Admin123@orcl file=/media/sf_vboxEx/exp_OrdMgmt.dmp log=PTS_DW_OBIAimp.log full=y;
