7 System Replication ?SAP HANA System Replication is a mechanism ensuring the high availability of your SAP HANA System . System Replication is SAP's recommended configuration for addressing SAP HANA outage reduction due to planned maintenance, faults, and disasters. It supports a recovery point objective (RPO) of 0 seconds and a recovery time objective (RTO) measured in can I learn about SAP HANA System Replication in this guide?Before configuring your System Replication landscape, it's important to learn about basic will have to take decisions related to the used operation and Replication modes.
8 The selected operation mode determines what types of data packages are sent to the secondary System . The operation mode determines also which technique (data retention or log retention) is used to achieve a resync whenever System Replication is out of sync. The network connection between the primary and the secondary systems is also important, because it impacts the overall performance of the systems involved in a System Replication landscape. Finally, in System Replication landscapes you can run also other systems (for example, DEV, QA systems, or even productive systems) on the secondary System s hardware while the primary System is in production.
9 For information on these aspects, see SAP HANA System Replication : Basic checking all the necessary prerequisites for configuring System Replication , you can use the SAP HANA cockpit, the SAP HANA studio, or the hdbnsutil command line tool to configure System Replication . At this point, it's also useful to know how to initialize the secondary System , how to change the chosen operation or Replication mode, or how to add or remove hosts. You can enable the full sync option in a synchronous System Replication to reach a true RPO=0. For information on these aspects, see SAP HANA System Replication : Configuration.
10 This chapter also provides an overview of the configuration parameters, a command line reference, as well as information about SAP HANA tenant database systems in a System Replication configuration, and the System Replication setup for XS next how to perform a takeover and a failback for planned or unplanned downtimes of the primary System . You can perform a standard takeover, a takeover with handshake, or an invisible takeover. For information, see SAP HANA System Replication : Takeover and quickly access again data, which was deleted in the original System , you can prepare your System Replication landscape for secondary time travel.
