SAP S/4 HANA stands for SAP Business Suite for SAP HANA and it provides simplified user experience, business processes and data models.SAP S/4 HANA is built on following features −Simplified data modelsFiori User interfaceGuided Configuration

In SAP HANA, following permanent license type is supported −Unenforced License: When you use an unenforced license key in SAP HANA and consumption of HANA system exceeds the license amount of memory, it doesn’t effect the operation of SAP HANA database.Enforced License: When an Enforced license key is installed and consumption of HANA system exceeds the license amount of memory, HANA system gets locked. If this situation occurs, HANA system has to be restarted or a new license key should be requested and installed.

This details can be checked from M_LICENSE view in HANA database. Try executing below query in SQL editor −SELECT EXPIRATION_DATE, ENFORCED, PERMANENT, LOCKED_DOWN FROM "SYS"."M_LICENSE" ;When Enforced value column is shown false so it means that license in use is not Enforced and you are using unenforced license.

basepath_logvolumes_es provides the default path to the dynamic tiering log directory (log_es). This path must be available to the dynamic tiering host, but need not be available to HANA hosts. Avoid including the default installation directory in the path.Value − File Path          Default − /HANA/log_es/

basepath_datavolumes_es parameter provides the default path to the dynamic tiering data directory (data_es). This path must be available to the dynamic tiering host, but need not be available to HANA hosts. Avoid including the default installation directory in the path.Value − File PathDefault − /HANA/data_es/

M_SAVEPOINTS view stores Current and historical savepoint statistics. There is column DURATION which tells the total time taken by savepoint.You can extract the following information from the numbers in this view −CRITICAL_PHASE_DURATION shows the period of time during which the updaters were blocked in a savepoint. Normally, this should be in the milliseconds range, except for a global savepoint for data backup, which may take longer due to global synchronization across all nodes. If the critical phase duration is too long, there is probably some problem (e.g., I/O load is too high).DURATION shows the total time taken by a savepoint. ... Read More

M_SAVEPOINT_STATISTICS view shows information about executed savepoints.This view contains columns- START_TIME, STATE, VERSION and LAST_* relate to the last executed or currently-executing savepoint.Following information is available −

This can be checked using M_SAVEPOINT_STATISTICS. This view has a resettable counterpart. This means, you can also see the values since the last reset in the dependent view: M_SAVEPOINT_STATISTICS_RESET.To reset the values, use the SQL command −ALTER SYSTEM RESET MONITORING VIEW SYS.M_SAVEPOINT_STATISTICS_RESETor the management console command −monitor reset -n M_SAVEPOINT_STATISTICS_RESET
