You can create replication definitions using extended limits for both replicate and standby databases. Extended limits are defined as:
Wide columns – data rows containing more than 255 to a maximum of 32768 bytes.
More columns – replication definitions containing more than 250 up to a maximum of 1024 columns in a replication definition.
Wide data – data rows up to the size of the data page on the data server. Adaptive Server version 12.5 and later supports page sizes of 2K, 4K, 8K, and 16K.
Wide messages – messages larger than 16K.
