Load data to remote DB using sqlldr

Question

I wanted to load data to remote db using sqlldr.I did it using following command

>sqlldr GANUKA/GANUKA@jdbc:oracle:thin:@172.21.0.180:1521:orcl control=D:\Work\CLSTMAS.ctl 
log=D:\Work\CLSTMAS.log

But it gives the following error.

SQL*Loader-704: Internal error: ulconnect: OCIServerAttach [0]
ORA-12154: TNS:could not resolve the connect identifier specified

Need a help

Answer 1

You're mixing up two different worlds here. One is the OCI world where sqlldr lives. It expects Oracle instance names defined in TNSNAMES.ORA (or a similar service). The other world is the JDBC world that uses connection identifiers with words like "jdbc" or "thin".

So you have two options:

• If your environment has a proper TNS setup, you have to change the command line to something like sqlldr GANUKA/[email protected] control=...

• If not, you can use an Easy Connect string: sqlldr GANUKA/GANUKA@//172.21.0.180:1521/orcl control=...
