Ha avuto lo stesso problema, anche dopo aver cambiato set lines a un gran numero:
select * from dba_directories;
OWNER DIRECTORY_NAME
------------------------------ ------------------------------
DIRECTORY_PATH
---------------------------------------------------------------------------------------------------------------------------------------------------------------
SYS DPUMP_DIR
C:\xxx
SYS CLEAN_PUMP_DIR
D:\yyy
SYS TCMCLEAN_DPUMP_DIR
C:\zzz
Il modo per farlo era usare anche:set wrap off
OWNER DIRECTORY_NAME DIRECTORY_PATH
------------------------------ ------------------------------ ------------------------------------------
SYS DPUMP_DIR C:\xxx
SYS CLEAN_PUMP_DIR D:\yyy
SYS TCMCLEAN_DPUMP_DIR C:\zzz
