Something that I didn't mentioned before (because it is of a little value to the original question asked):
When you use sql*loader in direct mode then it would create the table by itself - without using Oracle (or rather by itself because it is Oracle itself). This is why it can be fastest solution - you skip one interface (possibly more).
When using sql*loader in direct mode you should remember that it has a lot of constraints (ex. it "locks" the table). When dealing with huge amount of data (ex. terabytes of data per hour) then you are probably sentenced to use that option and multiple tricks/hacks. In any other case - establish a connection (...)

apache::session::oracle
Session::Oracle(3) User Contributed Perl Documentation Session::Oracle(3)
NAME
Apache::Session::Oracle - An implementation of Apache::Session
SYNOPSIS
use Apache::Session::Oracle;
#if you want Apache::Session to open new DB handles:
tie %hash, 'Apache::Session::Oracle', $id, {
DataSource => 'dbi:Oracle:sessions',
UserName => $db_user,
Password => $db_pass,
Commit => 1
};
#or, if your handles are already opened:
tie %hash, 'Apache::Session::Oracle', $id, {
Handle => $dbh,
Commit => 1
};
DESCRIPTION
This module is an implementation of Apache::Session. It uses the Oracle backing store and no locking. See the example, and the
documentation for Apache::Session::Store::Oracle for more details.
USAGE
The special Apache::Session argument for this module is Commit. You MUST provide the Commit argument, which instructs this module to
either commit the transaction when it is finished, or to simply do nothing. This feature is provided so that this module will not have
adverse interactions with your local transaction policy, nor your local database handle caching policy. The argument is mandatory in order
to make you think about this problem.
This module also respects the LongReadLen argument, which specifies the maximum size of the session object. If not specified, the default
maximum is 8 KB.
AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>.
