Function strings are added to the Replication Server default rs_hanadb_function_class.
The function string class replaces several default Replication Server
function strings with custom function strings designed to communicate with an SAP HANA
database data server and access replication-related tables and procedures.
Warning! ExpressConnect for
SAP HANA Database supports the replication of LOB columns that use default Replication
Server function strings for text and image processing. ExpressConnect for SAP HANA
Database does not support custom function strings for text and image processing. If you
override the default Replication Server LOB processing with custom function strings for
rs_writetext, rs_textptr_init, or other LOB-related function strings, text and image
processing will
fail.
