Determine the directory in which to install the replication components.
Replication Agent, Replication Server, and ECDA are installed in the same base directory, which is identified by the SYBASE environment variable. Select a path on the host drive to be the recipient of the Sybase installation and configuration activities. Replication Agent must be installed on a host from which it can directly access the primary Microsoft SQL Server instance transaction log.
Replication Agent 15.6 uses the RAX-15_5 directory name. If you have an existing Replication Agent 15.5 installation and do not want to overwrite it, install Replication Agent 15.6 in a different location.
