Is there a way to connect to an oracle database without installing a separate oracle client and
without making special client settings?
A few postings below, somebody posted that there is a way to copy only some files from the oracle client
to make the connection work (for example via cx_Oracle)
Does anybody know?

    AFAIK you need -at least- the oracle instant client. Which is considerably smaller than the Oracle client, BTW. Hope somebody can probe me wrong.

    It is correct that you will need some so libraries for cx_oracle to work. So you need an Oracle database home, client home or at least instant client home to have those libraries.
