Should you gather system statistics on Exadata ?

I got a questions from one user of Exadata: 

1.Do we need to gather system statistics on Exadata ?
2. How to gather system statistics on Exadata ?
3. If I run the command exec dbms_stats.gather_system_stats ('EXADATA') - how to point the start time and end time?

1.Do we need to gather system statistics on Exadata ?


The optimizer cost formula is 

cost =  (#srds * sreadtm + #mrds * mreadtm + #cpucycles / cpuspeed) / sreadtm
 
   #srds                 number of single block reads
   sreadtm               single block read time
   #mrds                 number of multi block reads
   mreadtm               multi block read time
   #cpucycles            number of cpu cycles
   cpuspeed              cpu cycles per second

 

As documentation say: "The cost is an internal numeric measure that represents the estimated resource usage for a plan. The cost is specific to a query in an optimizer environment. To estimate cost, the optimizer considers factors such as the following:
  • System resources, which includes estimated I/O, CPU, and memory .... "

 So, in order to generate an optimal plan, the optimizer must know the characteristics of the equipment.

 10.2.4 System Statistic: "  The system statistics describe hardware characteristics such as I/O and CPU performance and utilization.
System statistics enable the query optimizer to more accurately estimate I/O and CPU costs when choosing execution plans. The database does not invalidate previously parsed SQL statements when updating system statistics. The database parses all new SQL statements using new statistics. "

Table 15-2  Optimizer System Statistics in the DBMS_STAT Package
Parameter Name Description Initialization Options for Gathering or Setting Statistics

cpuspeed

CPU speed is the average number of CPU cycles per second.

At system startup

Set gathering_mode = NOWORKLOAD, INTERVAL, or START|STOP, or set statistics manually.

ioseektim

I/O seek time equals seek time + latency time + OS overhead time.

At system startup

Set gathering_mode = NOWORKLOAD or set statistics manually.

iotfrspeed

I/O transfer speed is the rate at which an Oracle database can read data in the single read request.

At system startup

Set gathering_mode = NOWORKLOAD or set statistics manually.

maxthr

Maximum I/O throughput is the maximum throughput that the I/O subsystem can deliver.

None

Set gathering_mode = NOWORKLOAD, INTERVAL, or START|STOP, or set statistics manually.

slavethr

Slave I/O throughput is the average parallel slave I/O throughput.

None

Set gathering_mode = INTERVAL or START|STOP, or set statistics manually.

sreadtim

Single block read time is the average time to read a single block randomly.

None

Set gathering_mode = INTERVAL or START|STOP, or set statistics manually.

mreadtim

Multiblock read is the average time to read a multiblock sequentially.

None

Set gathering_mode = INTERVAL or START|STOP, or set statistics manually.

mbrc

Multiblock count is the average multiblock read count sequentially.

None

Set gathering_mode = INTERVAL or START|STOP, or set statistics manually.

Unlike table, index, or column statistics, Oracle does not invalidate already parsed SQL statements when system statistics get updated. All new SQL statements are parsed using new statistics.

But there is another view on this question: https://blogs.oracle.com/optimizer/should-you-gather-system-statistics

 

2. How to gather system statistics on Exadata ?

 13.4 Gathering System Statistics Manually

 166.7.53 GATHER_SYSTEM_STATS Procedure 


Rules:

  • Capture system statistics when the database has the most typical workload 
  • Capture system statistics during not less than 1-2 hours

Also you can set YOUR OWN VALUES:

1.      begin
dbms_stats.set_system_stats('sreadtim',2); -- define single blocks reads to 2 ms
dbms_stats.set_system_stats('mreadtim',5); -- define multiblock reads to 5 ms
end;


 3. About  dbms_stats.gather_system_stats ('EXADATA')

 The dbms_stats.gather_system_stats('EXADATA') - does not gather statistics, it simply SET SOME CONSTANTS:

For example, on my notebook i have defaul values before dbms_stats.gather_system_stats('EXADATA'):

SQL> select * from aux_stats$;

SNAME                  PNAME              PVAL1    PVAL2

SYSSTATS_MAIN          MREADTIM

SYSSTATS_MAIN          CPUSPEED

SYSSTATS_MAIN          MBRC

SYSSTATS_MAIN          MAXTHR

SYSSTATS_MAIN          SLAVETHR

After :

SQL> delete * from aux_stats$;
SQL> commit;
Commit complete.

SQL> exec dbms_stats.gather_system_stats('EXADATA');
PL/SQL procedure successfully completed.

SQL> select * from aux_stats$;

SNAME                  PNAME             PVAL1    PVAL2

SYSSTATS_MAIN          CPUSPEED

SYSSTATS_MAIN          MBRC    
              83
SYSSTATS_MAIN          MAXTHR

SYSSTATS_MAIN          SLAVETHR

13 rows selected.

As you can see dbms_stats.gather_system_stats('EXADATA')simply set

CPUSPEEDNW     2987
IOSEEKTIM 
      10
IOTFRSPEED   204800

MBRC      
     83

Or dbms_stats.gather_system_stats('EXADATA') calculated these values ? 

Let trace dbms_stats.gather_system_stats('EXADATA') :


SQL> alter session set events '10046 trace name context forever, level 4';

SQL> exec dbms_stats.gather_system_stats('EXADATA');

SQL> alter session set events '10046 trace name context forever, level 0';
