Replication Server 15.7 is released as the Enterprise Edition.
Replication Server 15.7 includes enhancements to real-time loading (RTL) replication to Sybase® IQ. If you are using the Replication Server Real-Time Loading Edition, you can use the RTL enhancements by upgrading to Replication Server 15.7.
Although real-time loading is supported on all platforms that Replication Server supports, Replication Agent for Oracle (RAO) is not available on Linux on POWER or on Sun Solaris x64. However, you can run RAO on any of the platforms it supports. For platforms on which RAO is available, see the Installation Guide for Replication Agent in the Replication Server Options documentation.
