What are the merge methods that are triggered by the SAP HANA system? (Choose two.)
The merge methods triggered by the SAP HANA system include 'Critical' and 'Auto'. A 'Critical' merge is triggered automatically when the system reaches a condition that could compromise stability, such as an oversized delta storage. The 'Auto' merge method is utilized to periodically manage merging activities without manual intervention, ensuring optimized system performance.
HA200-SAP HANA 2.0 SPS06 - Installation and Administration. To keep the system stable, the database can trigger a critical merge. For example, when auto merge is disabled and no smart merge hints are sent to the system, the size of the delta storage can grow too large for a successful delta merge to occur. The system initiates a critical merge automatically when a certain threshold is passed.
