The 64-bit version of Replication Server for HP-UX Itanium uses the libtcl64.cfg file to provide configuration information such as driver, directory, and security services for Open Client/Server™ applications.
The 64-bit version of Replication Server for HP-UX Itanium is compiled with the 64-bit Sybase Open Client/Server. Therefore, the 64-bit version of Replication Server for HP uses the libtcl64.cfg file for HP-UX Itanium, instead of the 32-bit libtcl.cfg file.
