Find if the Oracle Client Software is 32-Bit or 64-Bit ?

We can find whether Oracle Client Software is 32-Bit or 64-Bit by using the following :

Check for the directories :

1) $ORACLE_HOME/lib32
2) $ORACLE_HOME/lib

% ls -l $ORACLE_HOME/lib32
% ls -l $ORACLE_HOME/lib


If the two directories $ORACLE_HOME/lib32 and $ORACLE_HOME/lib are existing then it is 64 bit client.
If there is only an ORACLE_HOME/lib directory then it is 32 bit client.
