SQL*Loader-704 Error
Published: 20 Aug 2008
While using Oracle’s SQL Loader utility the other day, I ran into a subtlety which wasn’t obvious. Most of the documentation out there describes the userid param as just taking user/pass. But it actually can take the user/pass@SID form as well. If you get an exception message something like the following:
SQL*Loader-704: Internal error: ulconnect: OCIServerAttach [0]
ORA-12541: TNS:no listener
try qualifying your sqlldr command with .world:
so
sqlldr userid=user/pass@yourSID control=test.ctl
becomes
sqlldr userid=user/pass@yourSID**.world** control=test.ctl
