  1. SAP HANA Database Replication – An Overview

  2. SAP is one of the top companies in the world, specializing in software development and the management of developing solutions and business processes that help robust data processing and flow of information. System replication is when SAP HANA database is copied to another location that might be on-premises or outside that specific business environment. The SAP database can consistently keep in sync with the source database during replication.

  3. Hence, when selecting a target system for SAP data replication, it is necessary to first select a specific replication mode. An SAP replication tool makes it easy for SAP users to integrate and extract their SAP data with other forms of data. This data can then be loaded into their SAP databases, SAP data warehouse, Hadoop data lake, or other data repositories, either on-premises or in the cloud. With the right SAP data replication solution, it is possible to easily and efficiently select, copy and move the SAP data to specific locations whenever needed. Along with change data capture (CDC) technology, real-time data warehousing and data integration can be done without any drop or lag in performance or operational impact. • SAP data replication tools ensure that firms can extract and consolidate data from their SAP applications and components and deliver the data to their preferred platforms. It helps them to increase the value of their SAP data, customize their approach to SAP analytics and respond quickly and with agility to new technologies to keep in line with evolving market conditions and trends.

  4. Implementing SAP data replication is often a challenge. It is because SAP systems comprise thousands of tables with complex relationships as well as proprietary data formats making data inaccessible outside the SAP framework. This structural complexity means that integrating data for analytics is often costly and time-consuming. • Most of the top companies and corporates and the world’s largest organizations run and analyze their operations on SAP systems. This is because new platforms and technologies require faster processing of data, real-time data warehousing, and advanced data analytics. Hence, forward-thinking firms are now looking for ways by which SAP data can be made available to the data lakes, data warehouses, and other analytics platforms, either on-premises or in the cloud. • There are four modes to carry out SAP data replication. • Synchronous In-Memory Mode where once the log is transmitted, the primary node or the source database waits for a confirmation message from the target node or secondary database. • Synchronous Mode where the primary node waits and stops the transaction until it receives an acknowledgment from the secondary node. • Synchronous Full Sync Mode where there is zero-loss of data because the process blocks the transaction on the primary mode till the secondary node completes the replication. • Asynchronous Mode where the primary mode does not stop its transactions until the secondary node sends confirmation. • The mode used for SAP data replication depends on their specific requirements.
