SAP HANA Cockpit for Offline Administration

Overview

Offline Administration and Diagnosis The SAP HANA cockpit for offline administration is a

version of the SAP HANA cockpit that communicates

with SAP HANA using SAP Host Agent.

You can use it to perform administration tasks, such

as starting the system or troubleshooting a system

experiencing performance problems, as operating

system user <sid>adm.

Content is displayed as tiles that function as entry

points to individual applications.

However, there are no groups or tile catalogs, and it

is not possible to modify the content or the

homepage.

Start/Restart/Stop System

Start/Restart/Stop The tile indicates the system

status: Initializing, Running,

Stopping, or Stopped.

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.



Diagnosis Files

Log and Trace Files The Diagnosis Files tile opens

the Diagnosis Files app where

you can access log and trace

files, as well as a mixture of other

diagnosis, error, and information files.

To diagnose and analyze errors while SAP

HANA is stopped or cannot be reached

due to performance problems, you can

check these diagnosis files for errors.

Click a file to navigate to its contents.

Alternatively, you can click the download

button to download the file to the

download directory of your browser on

your client.



Diagnosis Files

Diagnosis Information

Collection The Diagnosis Files app also

allows you to trigger the collection

of diagnosis information into a zip file,

which you can then download and attach

to a support message, for example.

When you click Collect in the footer bar

you can then specify the scope of

information to be collected by clicking one

of the following options:

– Diagnosis Information

– RTE Dump Files

The system collects the relevant

information and saves it to a zip file. This

may take some time and runs in the

background.



Troubleshoot Unresponsive System

Troubleshoot

Unresponsive System When a system cannot be

reached by SQL or is experiencing

performance problems, you or an SAP

support engineer can access diagnosis

information and perform emergency

operations to resolve the situation.

When you click on the Troubleshoot

Unresponsive System tile, the system

displays information about all connections,

transactions, blocked transactions, and

threads in the system.

If necessary, you can cancel individual

connections and transactions, or even

cancel all transactions.

SAP HANA Database


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.


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.
