On Linux platforms, the name of the 'arcmain' executable file will be changed to specifically identify the 32-bit version and the 64-bit version of 'arcmain'. The 32-bit version will be renamed to 'arcmain32', while the 64-bit version will remain 'arcmain'. For more details on this name change plus related information, please see the 15.10 Teradata Archive/Recovery Utility Reference manual (B035-2412), Chapter 1, section "Starting ARCMAIN from Linux and Windows XP/Server 2003". Please note that this change is only for Linux.
