Performance Tuning with SQLTXPLAIN (SQLT) with Examples in Oracle | Oracle Database Performance Tuning Tutorial -19

Hi,

I will explain SQLTXPLAIN (SQLT) Usage with Examples in Oracle in this article.

 

You can read the previous article of SQLTXPLAIN (SQLT) with the following link.

Oracle SQLTXPLAIN (SQLT) Tips and Tricks | Oracle Database Performance Tuning Tutorial -18

 

 

 

Now Let’s use sqltxtract method of SQLTXPLAIN (SQLT) as follows.

You need to find the SQL_ID from v$sql or AWR reports for this method.

*** NOTE:
*** If you get error below it means SQLTXPLAIN is not installed:
*** PLS-00201: identifier 'SQLTXADMIN.SQLT$A' must be declared.
*** In such case look for errors in NN_*.log files created during install.

*** NOTE:
*** If running as SYS in 12c make sure to review sqlt_instructions.html first

SQLT_VERSION
----------------------------------------
SQLT version number: 19.1.200226
SQLT version date : 2020-02-26
Installation date : 2020-08-24/15:31:52

NOTE:
You used the XTRACT method connected as MEHMETSALIH.

In case of a session disconnect please verify the following:
1. There are no errors in sqltxtract.log.
2. Your SQL 5hquy4x1r7a2n exists in memory or in AWR.
3. You connected as the application user that issued original SQL.
4. User MEHMETSALIH has been granted SQLT_USER_ROLE.

In case of errors ORA-03113, ORA-03114 or ORA-07445 please just
re-try this SQLT method. This tool handles some of the errors behind
a disconnect when executed a second time.

To actually diagnose the problem behind the disconnect, read ALERT
log and provide referenced traces to Support. After the root cause
of the disconnect is fixed then reset SQLT corresponding parameter.

To monitor progress, login into another session and execute:
SQL> SELECT * FROM SQLTXADMIN.sqlt$_log_v;

... collecting diagnostics details, please wait ...

In case of a disconnect review log file in current directory
If running as SYS in 12c make sure to review sqlt_instructions.html first

SQL Text : select * from MSDBA.TKGM_SERVIS_LOG where
vatandaslik_no=32216345040

-------------------------------------------------------------------------------
FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------

1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
A potentially better execution plan was found for this statement.

Recommendation (estimated benefit: 95.88%)
------------------------------------------
- Consider accepting the recommended SQL profile to use parallel execution
for this statement.
execute dbms_sqltune.accept_sql_profile(task_name => 'sqlt_s67096_mem',
task_owner => 'MEHMETSALIH', replace => TRUE, profile_type =>
DBMS_SQLTUNE.PX_PROFILE);

Executing this query parallel with DOP 27 will improve its response time
95.89% over the original plan. However, there is some cost in enabling
parallel execution. It will increase the statement's resource consumption by
an estimated 11.04% which may result in a reduction of system throughput.
Also, because these resources are consumed over a much smaller duration, the
response time of concurrent statements might be negatively impacted if
sufficient hardware capacity is not available.

The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.

Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0

Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0

2- Index Finding (see explain plans section below)
--------------------------------------------------
The execution plan of this statement can be improved by creating one or more
indices.

Recommendation (estimated benefit: 65.25%)
------------------------------------------
- Consider running the Access Advisor to improve the physical schema design
or creating the recommended index.
create index MSDBA.IDX$$_1CBD70001 on MSDBA.TKGM_SERVIS_LOG(TO_NUMBER("VATAND
ASLIK_NO"));

Rationale
---------
Creating the recommended indices significantly improves the execution plan
of this statement. However, it might be preferable to run "Access Advisor"
using a representative SQL workload as opposed to a single statement. This
will allow to get comprehensive index recommendations which takes into
account index maintenance overhead and additional space consumption.
