Class-level translations for non-ASE data servers are defined in connection profiles and connection profiles install the class-level translations.
See the Replication Server Heterogeneous Replication Guide to find a description of the connection profiles for each supported non-ASE database.
Class-level translations change the datatype of system-defined variables as well as column values.
For example, if a class-level translation changes datetime to rs_db2_timestamp, the rs_origin_begin_time system-defined variable, which is datetime, is translated to rs_db2_timestamp for that connection.
