Re: Thick vs thin client - 11g R2

Hi Sandra,

Regarding lib32 we have experienced a similar problem with Oracle 11gR2. On a Linux 64 bit platforms all Oracle 64 bit client installations included both lib32 and lib (with 64 bit libs) directories. Since 11gR2, lib32 directory has been taken out from a Oracle 64 bit installation on Linux 64 bit.
The workaround that i got from Oracle support is to install 32 bit client on 64 bit Linux platform. This is possible only on Linux. Please notice that 32 bit Oracle client does not have lib32 either but only a lib directory.
All this is applicable of course if you need to run 32 bit application on 64 bit Linux platform. This can happen with some kind of a legacy application that none wants to change or test .
