Hello Stecal,

Thanks for reply.

yes. my scott user have dba granted to him.. I did not understand exactly about session you said .. but I was able to export using following command

C:\>exp USERID=scott/tiger@mytestdb file=c:/latest.dmp full=y;

I think problem was because of 2 databases I have 1 is mytestdb and other is db1 and when I tried with previous command it might be taking scott user of db1 and not of mytestdb.. and I think by session you mean to say with which database I was connected. may be I am wrong.

Regarding old export .. it seems to work fine using 11g also. yes you are right that it is old version but.. I used what I find first during my google search.. though I am learning things during my project progress.

Again thanks for your reply. May be I did not ask question as much perfectly as it should be.

But I found the solution using @serviceid in export command.

Thanks.
