do the export in source db
export ORACLE_SID=
export ORACLE_HOME=
export PATH=$ORACLE_HOME/bin
expdp system/password schemas=schemaname directory=directoryname parallel=2 dumpfile=dumpfilename_%U.dmp log=logfilename

transfer the dump file from source to destination database

In the destination database,

create the tablespace and the schema structure

export ORACLE_SID=
export ORACLE_HOME=
export PATH=$ORACLE_HOME/bin
impdp system/password remap_tablespace=sourcetablespacename:destinationtablespacename remap_schema=sourceschemaname:destinationschemaname table_exists_action=truncate directory=directoryname parallel=2 dumpfile=dumpfilenames log=logfilename
