SAP HANA Available, Used & Deprecated Features
In this blog post, I would be sharing a very basic information about SAP HANA features.
With every latest revision, we hustle sometimes in finding out whether a SAP HANA feature is newly introduced or deprecated from previous versions etc. This information is now easily available with SAP HANA monitoring views M_FEATURES and M_FEATURE_USAGE.
From Monitoring Views
These views are available for all Hana versions 1.0 and 2.0 as well.
SYS.M_FEATURES : Provides information about all supported features. Eg:
| COMPONENT_NAME | FEATURE_NAME | FEATURE_VERSION |
| ABSTRACT SQL PLAN | CAPTURE | 4 |
| ABSTRACT SQL PLAN | PLAN GENERATION | 3 |
| BACKUP RECOVERY | BACKUP SCHEDULER | 5 |
SYS.M_FEATURE_USAGE : Provides detailed feature usage statistics. In this view, column name ‘IS_DEPRECATED’ if set to ‘TRUE’ it means feature is deprecated otherwise it’s available. Eg:
| COMPONENT_NAME | FEATURE_NAME | IS_DEPRECATED | OBJECT_COUNT | CALL_COUNT | LAST_TIMESTAMP | LAST_CONNECTION_ID | LAST_USER_NAME | LAST_APPLICATION_USER_NAME | LAST_APPLICATION_NAME | LAST_APPLICATION_SOURCE | LAST_STATEMENT_ID | LAST_STATEMENT_HASH |
| SQL CREATE | WITH PARAMETERS TREX_FLAGS | FALSE | ? | 0 | ? | ? | ? | ? | ? | ? | ? | ? |
| HIERARCHY | GENERATOR FUNCTION | FALSE | ? | 0 | ? | ? | ? | ? | ? | ? | ? | ? |
| HIGH AVAILABILITY | HOST AUTO FAILOVER | TRUE | 25 | 13914 | 15:11.0 | -1 |
From SQL statements
You can use the following SQL statements available via SAP Note 1969700 to display this information:
| SQL statement | Details |
| SQL: “HANA_Features” | Overview of SAP HANA features available in the system, including their version |
| SQL: “HANA_Features_Usage” | Overview of SAP HANA features available in the system, including their usage and deprecation state |
Deprecated Features with HANA 2.0
There exists a nice SAP Note 2425002 which provides further details for features being deprecated with SAP HANA 2.0.
Earliest removal of a deprecated feature will be one SPS after deprecation start. The table below lists the specific information, migration steps to follow, and so on.
| Description | M_FEATURE_USAGE. COMPONENT_NAME |
M_FEATURE_USAGE. FEATURE_NAME |
