3.1 Downloading and Installing the Oracle Database Client Software

Download and install Oracle Database Client 11g Release 2 by completing the following steps:

  1. Download the Instant Client for Mac OS X (Intel) (32-bit and 64-bit) package from the Instant Client Downloads page on Oracle Technology Network at
  2. Create a directory on your computer, for example, instantclient. Choose a directory to install the Oracle Instant Client and unzip the downloaded zip file in that directory. The unzipped file creates the instantclient_11_2 directory.

  3. Set the DYLD_LIBRARY_PATH and the NLS_LANG environment variables to the full path of the instantclient_11_2 directory. For example, if you unzipped the Instant Client zip file in the /bin/oracle directory, then set the DYLD_LIBRARY_PATH environment variable to /bin/oracle/instantclient_11_2.

    Refer to "Instant Client Light Requirements" for information about setting the NLS_LANG environment variable to the required character set.

    This completes the installation of Oracle Database Client. To connect to the Oracle Database server, run your client from the Oracle Database Instant Client environment.
