How to find if the Oracle Client Software is 32-Bit or 64-Bit ?
here you can have some ways to find it.
You can find whether Oracle Client Software is 32-Bit or 64-Bit by using the following :
1.Check the sqlplus binary
% file $ORACLE_HOME/bin/sqlplus
64-bit will show 64-bit.
32-bit will show 32-bit or not specify wordsize
2.Check for the directories :
$ORACLE_HOME/lib32
$ORACLE_HOME/lib
% ls -l $ORACLE_HOME/lib32
% ls -l $ORACLE_HOME/lib
If the two directories $ORACLE_HOME/lib32 and $ORACLE_HOME/lib exist, then it is 64 bit client.
If you have only $ORACLE_HOME/lib you need to use method 1 as there are client versions (11.2)where $ORACLE_HOME/lib32 directory does not exist on 64-bit client installations.
