Sqlldr

[Knarayan]

Hi guys,

I have a strange problem with Sqlldr. Sometimes without any reason it hangs and it starts working only after I restart the database. Any clue what'st the problem.

Thanx in advance,

Kavita

Maybe you are experiencing a lock.

Run this query next time it happens to find out :
It will show the session that is blocking you.


select
L.sid session_id,
Substr(S.Username, 1, 10) as DBUser,
decode(L.type, 'MR','Media Recovery', 'RT','Redo Thread',
