Is it possible to install SQL*Loader without installing the whole Oracle package?
the comments above were what i was looking for.
the "instant client" has sqlplus, but does not have sqlldr.
sqlldr requres the (full) "client" which is hidden off of a tiny fine print link on the craptacular oracle site.
"Oracle Database 11g Release 2 Client (184.108.40.206.0) for Microsoft Windows (32-bit)" http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win32soft-098987.html
It seems, there is also a way to install SQL*Loader with instant clients: http://kimplove.blogspot.de/2010/08/installation-of-oracle-instant-client.html
I'm quite sure it is not supported by Oracle and you need a client installation like DCookie explained. But it could be a solution when you need to install it on multiple servers.
The alternative solution would be to make a installation like DCookie explained and create a rpm/deb from it and push it to multiple servers.
