Replication Server version 12.5 and later supports these extended limits for replication definitions:
More columns, to a maximum of 1024
Wide columns and parameters, to a maximum of 32768 bytes
Wide data rows to the width of the data page on the data server
Wide messages larger than 16K
If the Replication Server site version is 12.5 or later, Replication Server sets the LTL version automatically to 400 or higher. If RepAgent is running on Adaptive Server 12.5 or later, RepAgent sends data with extended limits only if Replication Server specifies an LTL version of 400 or higher at connect source time.
If the Replication Server site version is 12.1 or earlier, the LTL version is earlier than 400. If RepAgent is running on Adaptive Server 12.5 or later, Sybase recommends that you do not send extended-limits data to Replication Server 12.1 and earlier. You can specify how RepAgent handles extended-limits data by using the data limits filter mode parameter with config_rep_agent. See “Configuring RepAgent”.
