SAP Hana - Database Start/Stop/Restart

Sap Hana Architecture


  • The data belonging to a savepoint represents a consistent state of the data on disk and remains so until the next savepoint operation has completed.
  • Redo log entries are written to the log volumes for all changes to persistent data.

In the event of a database restart (for example, after a crash):

  • the data from the last completed savepoint can be read from the data volumes,
  • and the redo log entries written to the log volumes since the last savepoint can be replayed.
