The Non unicode Adapter is a 32 bit application on Windows, Solaris, HP UX, Linux and AIX platforms. It’s 64 bit only in HP Itanium.

If the Non Unicode Adapter is used, Please make sure that the libraries, including the SAP libraries, being accessed by the adapter at runtime are 32 bit. On UNIX, this can be confirmed by running the ldd command on the adapter exe after setting the environment.

The Unicode Adapter is a 64 bit application on all platforms except Windows and Linux. Thus, if you are using the Unicode Adapter, please make sure that the libraries, including the SAP libraries, being accessed by the adapter at runtime are 64 bit. On UNIX, this can be confirmed by running the ldd command on the adapter exe after setting the environment.
