SDK/Open Server binaries like isql and bcp, share the same name between the 32-bit and 64-bit products. Installing ASE, SDK, or Open Server 64-bit products with other Sybase 32-bit products in the same Sybase installation, overwrites the 32-bit binaries causing issues with the peaceful coexistence of multiple products.
From SDK/Open Server 12.5.1 ESD #19 onwards, the 64-bit binaries are replaced with 32-bit binaries on all 64-bit UNIX platforms, except Sun Solaris x64.
Sun Solaris x64 64-bit will continue to release 64-bit binaries and not 32-bit binaries of Sun x86. This is because SDK/Open Server on Sun x86 32-bit does not support the Directory (LDAP) and Security (SSL) services, and neither do the 32-bit binaries like isql on this platform.
