how locate oracle software installation? ideas? please, help

for oracle 12.x , cx_oracle not available yet. need download instant client 11.x version.

go http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html , accept license agreement.

then download zip files names below

  • instantclient-sdk-linux.x64-11.2.0.4.0.zip
  • instantclient-basic-linux.x64-11.2.0.4.0.zip

and unzip them unzip command

unzip instantclient-sdk-linux.x64-11.2.0.4.0.zip unzip instantclient-basic-linux.x64-11.2.0.4.0.zip

both extracted common directory named "instantclient_11_2". add path below commands.

export oracle_home=/path-to_this/instantclient_11_2 cd $oracle_home ln -s libclntsh.so.11.1   libclntsh.so

open /etc/profile or .bashrc , following entries.

export oracle_home=/location/of/your/files/instantclient_11_2 export ld_library_path=$ld_library_path:$oracle_home

then source ~/.bashrc or source /etc/profile

and install these packages 

sudo apt-get install build-essential unzip python-dev libaio-dev

after use pip or pip3 according python version , install 

pip3 install cx_oracle

and try loading cx_oracle module in python interpreter.

hope helps.
