You 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.
On Linux the above method can be used or it can also be checked from the "uname -a" command
1) If the Operating System (OS) is x86 then the client installed is 32 bit.
2) If the OS is X86-64 then the client installed is 64 bit.
This is because , on Linux you can only install 32 bit client on 32 bit OS and 64 bit client on 64 OS
