It opens the System Operations app where you can start, restart, and stop the system. In a system with multitenant database containers, all tenant databases will be started/restarted/stopped. While the system is starting/restarting/stopping, the status of the individual services can be monitored in the System Operations app.

All rights reserved. 11 SAP HANA Database Monitoring Improvements Monitoring of DDL Statements Monitoring view M_EXECUTED_STATEMENTS records all DDL statements (e.g. table split/move) by default (can be disabled using parameter enable_ddl in global.ini, section executed_statements). Statements are traced in memory, and flushed in regular intervals to a file. The file size and flush interval are configurable as well as the max. number of trace files (parameters maxfilesize, maxfiles and trace_flush_internal). Connection Monitoring New column CLOSE_REASON in view M_CONNECTIONS now reveals the reason, why a session has been closed (e.g. because the connection client has been terminated, or because of an idle timeout). New columns COMMIT_MAX_EXECUTION_TIME, COMMIT_TOTAL_EXECUTION_TIME, COMMIT_AVG_EXECUTION_TIME and COMMIT_COUNT in view M_CONNECTION_STATISTICS record the time needed to perform a commit.

All rights reserved. 12 SAP HANA Database Monitoring Improvements SQL Statement Monitoring M_SQL_PLAN_CACHE now contains columns MAX_CALLED_THREAD_COUNT, TOTAL_CALLED_THREAD_COUNT and AVG_CALLED_THREAD_COUNT to show how many threads have been used to execute a specific query. Columns MAX_SERVICE_NETWORK_REQUEST_COUNT, TOTAL_SERVICE_NETWORK_REQUEST_COUNT and AVG_SERVICE_NETWORK_REQUEST_COUNT record TrexNet request counts in M_SQL_PLAN_CACHE. M_EXPENSIVE_STATEMENTS now includes column WORKLOAD_CLASS_NAME to show which workload class had been assigned to a specific statement execution. SQL statement hash is now included in trace files in case of error situations (e.g. out of memory situations) to easily identify which statement caused the problem. Statistics Service Alert data in the _SYS_STATISTICS.STATISTICS_ALERTS table is now deleted by default after a period of 42 days. The number of alerts in the system (that is rows in the table _SYS_STATISTICS.STATISTICS_ALERTS_BASE) now cannot exceed 1,000,000 by default. If this number is exceeded, the system starts deleting rows in increments of 10 percent until the number of alerts is below the maximum.
