Install Oracle Client 12c Access

Open tnsnames.ora in a text editor (Notepad, vi, nano). Add a definition:

MYDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver.example.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.example.com)
    )
  )
echo "Installing dependencies..."
yum install -y binutils gcc gcc-c++ glibc glibc-devel libaio 

libaio-devel libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel install oracle client 12c
pip install cx_Oracle

Set LD_LIBRARY_PATH (Linux) or PATH (Windows) to point to ORACLE_HOME/bin. Open  tnsnames
You are now presented with a summary of all the options you selected. Set LD_LIBRARY_PATH (Linux) or PATH (Windows) to point


If you downloaded the client from the Oracle website, it usually comes in a compressed format (e.g., .zip).


Now let's develop a practical feature using the installed Oracle Client:
