Service Availability Validation — verify that all critical SAP HANA database services are operational and available for business processing.
This investigation was performed in a SAP HANA sandbox environment to simulate a routine SAP BASIS service health check. The objective was to verify the operational status and availability of critical SAP HANA database services using the same structured monitoring methodology commonly applied by SAP BASIS administrators before business processing begins in production SAP environments.
Service availability directly affects the ability of users and applications to access SAP systems. Identifying service failures before business hours reduces operational risk and helps prevent unplanned downtime.
Established a session in SAP HANA Studio against SYSTEMDB@HDB to confirm successful connectivity to the target database prior to performing administrative activities.
SAP HANA Studio connected successfully to SYSTEMDB@HDB on host sapsystem, instance 00, user SYSTEM. The system tree (Backup, Catalog, Content, Provisioning, Security) was expanded and accessible.
The SAP HANA system view M_SERVICES was queried to validate the operational status and availability of database services supporting the SAP landscape. The review focused on confirming that critical HANA services were active and capable of supporting business processing.

Five services returned ACTIVE_STATUS = 'YES': compileserver (30010), daemon (30000), nameserver (30001), preprocessor (30002), and webdispatcher (30006) — all running on host sapsystem. Statement executed in 2 ms.

The M_SERVICES results were reviewed to verify the operational status of SAP HANA services. Particular attention was given to the ACTIVE_STATUS column because service availability directly affects database accessibility and application processing. The review confirmed that all listed services reported ACTIVE_STATUS = 'YES', indicating that they were operational at the time of analysis. Any service reporting ACTIVE_STATUS = 'NO' would require immediate investigation due to the potential impact on system availability and business operations.
All services returned by the M_SERVICES query were operational at the time of review. The compileserver, daemon, nameserver, preprocessor, and webdispatcher services all reported ACTIVE_STATUS = 'YES', confirming service availability across the reviewed SAP HANA environment. No service outages, communication failures, or abnormal service conditions were identified during the analysis.
