Distributed Application of Transactions in the DSI Thread for HVAR

Distributed application of transactions for high volume adaptive replication (HVAR) to SAP ASE databases maximizes parallel processing within transactions to improve replication performance for the data server interface (DSI) thread.

With distributed application of transactions, SAP Replication Server separates commands within transactions into multiple groups and applies the command groups in parallel to the replicate database instead of applying each command serially. Use the dt_apply parameter to enable distributed application of transactions.

See Distributed Application of Transactions in the DSI Thread in the Administration Guide Volume 2.

Note The replicate SAP ASE data server requires a separate license and configuration for distributed transaction management (DTM) to support distributed application of transactions from SAP Replication Server. See SAP ASE System Administration Guide: Volume 2 > Distributed Transaction Management > Enabling DTM features > Installing a license key.

Platform Support

dt_apply is available on all supported SAP Replication Server platforms except for Linux on IBM p-Series and Microsoft Windows. See the SAP Replication Server Release Bulletin for supported platforms.
