The figure above gives an overview of the Transaction Log-based Replication using This replication method is only recommended for customers that have been invited to use this technology during RTC of the SAP HANA product delivery if you are not part of this RTC group SAP recommends using trigger-based data replication using UAP LT (landscape Transformation) Relocation server because of the rich feature set offered by this replication technology The main component of this replication method is the system replication agent, which is part of the source system, SAP ERP, and the Sybase replication server that is to be implemented in SAP HANA Replication process in detail.
The figure above shows details of the data replication process and introduces the additional components of this replication method.
The initial load of business data needs to be executed only once to replicate the entire existing data set from the source system to the target, SAP HANA database The SAP HANA load controller, a component tab resides in SAP HANA, co-ordinates the entire replication process: it starts the initial load of source system data to the SAP HANA database in SAP HANA, and communicates with the Sybase replication server to co-ordinate the start of the delta replication The initial load can be executed while the source system is active as described briefly below:
In parallel to the initial load, the Sybase Replication Agent in the source system is started and details any data changes that accuse while the initial load already running to core every single change. This detection is performed by reading the logs for committed transactions of the source system database The Replication Agent uses the table metadata from the database to connect the row log information with the existing table names. In addition, the replication Agent transfers all relevant row log information vie TCP/IP connection to the Sybase replication server on the SAP HANA side. The Replication server creator SQL statements from the row log information received and sends these statements to the Sybase enterprise connect DATA access (ECDA) The ECDA connects to the SAP HANA database via open database connectivity (ODBC) driver and replicates the data changes from the source database by executing the SQL statements in the SAP – HANA database. The multi-version concurrency control (MVCC) of the SAP HANA database prevents locks.
The continuous delta replication captures the ongoing data changes in the source system in real-time once the initial load and the simultaneous delta replication have been completed all further data changes are captured and continuously replicated from the source systems to SAP HANA using the same process as the simultaneous delta replication described above.
This replication method requires the following components:
LT – Replication:
Source system LT Replication HANA system (LDH), server (DH2), (N62)
Provide T-code, LTR (in an SLT system)
