I am on windoes NT and oracle version 10.2.0.4 .
Doing exp full=y ; and getting ora-1466 error and exp returning with non zero return code.that error dose not comes if we use expdp.

FOR example i have tried a simple scenario-
whether there is one table(test1) present and one is not(test2).
exp tables=test1,test2

C:\>exp tables= test1,test2
