SAP HANA Savepoint Mechanism – Internal stages
SAP HANA hangs on in-memory data by making use of savepoints. Each of the SAP HANA services has its own separate savepoints. During the ongoing savepoint operation, SAP HANA carries out database flushes thus changing the required data from the memory to the data volumes. The data does belong to a savepoint and represents a consistent state of the data on the respective disk. It remains so until the next savepoint operation has been completed. Redo log entries are written to the log volumes for all changes to the persistent data. In the case of a database restart (for instance, after a crash), the data from given last completed savepoint can be actually read from the data volumes, and then one has to redo log entries written to the log volumes as the last savepoint can be replayed. What there is more to know? The frequencies of these savepoints are much defined and can be configured in the persistence section of the global.ini file (every 5 minutes by default). Savepoints are rather triggered off by a number of other operations such as data backup, and database shutdown and restart. You can thus trigger a savepoint manually by executing the following […]
