How does Sybase Replication Server capture data changes?


as far as I know Sybase Replication Server is a central component in a HANA-based enviroment when it comes to replicate data towards HANA engine.

I scan briefly through a white paper of Sybase, but I gives no technical description how the Sybase Replication Server captures data change on the source database.

Can someone gives here explanation?

All the best,

    Hi Guido,

    Replication server allows for near realtime asynchronous replication between heterogeneous datasources. It uses a RepAgent to read the transaction logs of the source databases then translates & sends it on to the destination databases.

    In the context of the HANA solution I expect it will just attach to existing database and feed HANA's in-memory database.

      Hello Marc,

      thanks for fair and hornest answer!

      I'm currently involved in SAP based project where we are migrated business on DB level, which is some kind of operation a heart. I personally have huge respect for this approach.

      Caputring the changes on DB level is a appoarch, but I personally think that you need to capture event on business object level. For exammple the SAP good old workflow knows events for business objects. Also in a ESA-driven application you should have some kind on eventing for business objects.

      For the time being the current approach might working for a kind of Proof-of-Concept,

      but on a mid and long-term based you need to RETHINK!

      All the best & Merry Christmas & Happy new year
