Configuring SQL*Plus Instant Client on Linux (from Client Media or Zip File) and UNIX

• Add the name of the directory containing the Instant Client files to the appropriate shared library path LD_LIBRARY_PATH, LIBPATH or SHLIB_PATH. Remove any other Oracle directories.
  For example on Solaris in the Bourne or Korn shells:
  LD_LIBRARY_PATH=/home/instantclient10_1:${LD_LIBRARY_PATH}export LD_LIBRARY_PATH
  
• Add the directory containing the Instant Client files to the PATH environment variable. If it is not set, then an absolute or relative path must be used to start SQL*Plus. Remove any other Oracle directories from PATH. For example:
  PATH=/home/instantclient10_1:${PATH}export PATH
  
• Set SQLPATH to the directory containing the Instant Client files so glogin.sql can be found. For example:
  SQLPATH=/home/instantclient10_1:${SQLPATH}export SQLPATH
  
• Set Oracle globalization variables required for your locale. A default locale will be assumed if no variables are set. See the Oracle Database Globalization Support Guide for more information.
  For example:
  NLS_LANG=AMERICAN_AMERICA.UTF8export NLS_LANG
