Multitenant Database Containers: Monitoring Concep

Specific properties of SAP HANA multitenant database containers regarding adminis

The system database plays a central role It is responsible for overall system and resource monitoring

It can initiate both restarts of the system database itself and of individual tenant databases

It can initiate both backups of the system database itself and of individual tenant databases.

Recoveries are always initiated by the system database

Tenant databases are always created/dropped by the system database

Resource limits for tenant databases are configured on the system database

Tenant databases are monitored individually

Alert, trace, parameter and user configuration is done for each tenant database individually

Visualization of execution plans will automatically display anOverviewpage

Key KPIs are displayed to provide an overview before

starting a detailed details

Plan Visualizer - Statement Stat

Visualization of execution plans for SQalso displays a set of statistics for eac

involved in the procedure

Provides easy drill-down into the mos

statement



23/37




Plan Visualizer - Tables Used

Provides an overview on which tables have been usedduring the processing of a statement

Displays 3 metrics per table:

maximum number of entries processed, i.e. the

overall output cardinality of any processing step

on that table in the statement execution.

number of accesses, i.e. how often a table has

been accessed during statement execution

maximum processing time, i.e. the maximumprocessing time across the possibly multiple table

accesses

Double-clicking on any row (table) leads to a corresponding operator list filtered for physical operators a

table.



24/37




Plan Visualizer - Network

For queries executed in a distributed landscape, the Networkview visualizes sequentialnetwork data transfers between different servers based on their given timestamps

Information displayed:

X-axis: servers involved

Y-axis: time elapsed since query execution

duration of network data transfers represented by rectangular bars

size of data transferred in bytes

Plan Visualizer - Performance Trace Displays list of operators for which performance trace data exists

The data can be viewed by selecting any of the operators

given in the list.

The view consists of two main sections:

left: list of operators you can select to view performance

trace data

right: performance trace data for the selected operator

Plan Trace

Collects SQL queries (along with their execution plans)executed in a given time frame for a particular application

(session).

Only 'SELECT' statements are currently traced - all other

kinds of statements including procedures are planned

to be supported in the future

Plan trace configuration can be accessed in two ways:

Context menu on a particular session inAdministration

editor -> Performance -> Sessions

Administrationeditor -> Trace Configuration tab

When an active trace is stopped, the Plan Trace Editor

will be opened automatically, displaying the traced queries

Double-clicking a particular statement (or using the

context menu entry 'Visualize Plan) displays the execution plan

SAP HANA Web-based Development Workbench

SQL Console Extended SQL Console (part of the "Catalog" perspective) to support implicit

and explicit performance measurement while executing a SQL statement

Implicit performance measurement provides

Execution Time information: DB, XS, and frontend layer

Additional information: table locks, system alerts.

Detailed performance analysis supports the repeated execution of statements

thus allows to check whether performance characteristics are stable

Expensive Statements Trace Available in the "Trace" perspective Supports filtering for passport-based application sessions

For each statement metrics such as start time, number of processed

records, etc. are displayed

Summary provides information on the overall SQL load:

number of statements executed

number of unique statements executed

number of result records

Memory Limit Enhancements

Memory Limit Enhancements

User specific memory limit in addition to the global statement memory limit

ALTER USER SET PARAMETER STATEMENT MEMORY LIMIT =

If both a global statement memory limit and a user statement memory limit are set, the user specific o

will precede

Unsetting the user parameter will bring the global statement memory limit into effect for the user

Setting the user parameter to 0 will disable any statement memory limit for the user

You can set the statement memory limit for a user in the Usereditor of the SAP HANA studio.

Statement Memory Limit Threshold Parameter statement_memory_limit_threshold in file global.ini, section memorymanager

Allows to specify a percentage of total memory (as per global_allocation_limit).

If this parameter is set, the global or user statement_memory_limit is only evaluated, if the total memo

threshold.

No statements have to be cancelled if the total memory usage is below this threshold.

This feature allows expensive statements, which consume more than the allowed statement memory

successfully during periods of low load, e.g. during the night.



29/37



CPU Time Measurement

CPU Time Measurement

Resource consumption collection has to be enabled manually:

Configuration file global.ini, section resource_tracking, parameters enable_tracking and cpu_time_me

Expensive statements trace contains column CPU_TIME which shows the CPU usage of the traced sta

Monitoring view M_SERVICE_THREADS shows CPU time values in columns CPU_TIME_SELF (CPU

CPU_TIME_CUMULATIVE (CPU time of thread and associated children)which are also shown in the

Administrationeditor in HANA studio

Additional Features

Shortened Restart Time

Fast HANA Restart

Restart time of SAP HANA is mainly determined by the time needed to load the row store into memory

Whenever the database was shutdown normally, the restart can be significantly sped up by re-using exi

memory segments

Parameter to enable this feature: file indexserver.ini, section row_engine: keep_shared_memory_over_

Preconditions for fast restart:

Usage of Embedded Statistics Service

Restart after normal shutdown

During index server shutdown phase

o No active write transactiono No versions on row store tables

o No locks on tables

Trace files indicate which kind of restart happens:Shutdown: Keeping RS shared memory at RowStore shutdown

Preconditions for reuse of RS shared memory is satisfied

RS shared memory will be used for RowStore segments at next service startup

Restart: Reattaching RS shared memory for RowStore segments2 RS segments loaded in 0.28 sec (457.143MB/s)

Additional Features

Web Dispatcher

Web Dispatcher

The internal HANA Web Dispatcher has been converted to a native HANA service named "webdispatch

previous standalone executable "sapwebdisp_hdb".

Main benefits and changes:

Administration (start/stop) and monitoring (CPU, memory) of the internal web dispatcher are now ava

Configuration via webdispatcher.iniin HANA studio. The previous profile sapwebdisp.pflis removed, s

automatically.

Changed trace file name to webdispatcher_._dev_webdisp.

Additional trace file webdispatcher_...trc contains information like

configuration changes etc. The web dispatcher admin tool is now accessible at http://:/sap/hana /xs/wdisp/admin. L

user that has role sap.hana.xs.wdisp.admin::WebDispatcherAdmin to use it.

In particular, you can use this tool to manage SSL certificates and other personal secure environment

HANA. SAP's command line cryptography tool SAPGENPSE is no longer required.
