The 64-bit version of Replication Server for HP 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 Itanium, instead of the 32-bit libtcl.cfg file.
Consider all references to libtcl.cfg in the Replication Server documentation as libtcl64.cfg for HP Itanium.
