The DBMS_AUTO_SQLTUNE package is the interface for managing the Automatic SQL Tuning task. Unlike DBMS_SQLTUNE, the DBMS_AUTO_SQLTUNE package requires the DBA role.

It further processes the audio according to the user's requirements and sends it through the audio device of the computer to the speakers.

Sep 01, 2015 This article discusses the automatic SQL tuning features of Oracle Database. Automatic SQL tuning automates the manual process, which is complex, repetitive, and time-consuming.When SQL statements are executed by the Oracle database, the query optimizer is used to generate the execution plans of the SQL statements. Sep 14, 2011 Automatic SQL Tuning In Oracle Database 11g September 14, 2011 Filed under: Oracle In Oracle 11g, we have SQL Tuning Advisor which is run automatically against high resource consuming SQL statements during the maintenance windows.

Release 2 (11.2.0.2).

The automated tuning process in Oracle 11g is implemented by a number of functions in the Oracle database: Automatic Database Diagnostic Monitor (ADDM) Takes input from the AWR reports which it analyses in order to identify potential bottlenecks. If the statistics level parameter is set to TYPICAL or ALL then the ADDM is ran Continue reading 'Automatic SQL Tuning in. Enabling Automated SQL Tuning in Oracle 11g To identify if Automatic SQL Tuning job is enabled and regularly running. Use the following query to determine if.

Using DBMS_AUTO_SQLTUNE

Overview

The DBMS_AUTO_SQLTUNE package is the interface to SQL Tuning Advisor (DBMS_SQLTUNE) when run within the Autotask framework. The database creates the automated system task SYS_AUTO_SQL_TUNING_TASK as part of the catalog scripts. This task automatically chooses a set of high-load SQL from AWR and runs the SQL Tuning Advisor on this SQL. The automated task performs the same comprehensive analysis as any other SQL Tuning task.

The automated task tests any SQL profiles it finds by executing both the old and new query plans. Automatic SQL Tuning differs from manual SQL tuning in one important way. If automatic implementation of SQL profiles is enabled (the default is disabled), then the database implements any SQL profiles that promise a great performance benefit. The implementation occurs at tuning time so that the database can immediately benefit from the new plan. You can enable or disable automatic implementation by using the SET_AUTO_TUNING_TASK_PARAMETER API to set the ACCEPT_SQL_PROFILES parameter.

In each maintenance window, the automated tuning task stores its results as a new execution. Each execution result has the same task name but a different execution name. Query the DBA_ADVISOR_EXECUTIONS view for information about task executions. Use the REPORT_AUTO_TUNING_TASK Function to view reports that span multiple executions.

Security Model

This package is available to users with the DBA role. For other users, you must grant the EXECUTE privilege on the package explicitly. Note that the EXECUTE_AUTO_TUNING_TASK procedure is an exception: only SYS can invoke it.

Users can call APIs in this package to control how the automatic tuning task behaves when it runs, such as enabling automatic SQL profile creation and configuring the total and per-SQL time limits under which the task runs. Because these settings affect the overall performance of the database, it may not be appropriate for all users with the ADVISOR privilege to have access to this package.

Summary of DBMS_AUTO_SQLTUNE Subprograms

Table 28-1 DBMS_AUTO_SQLTUNE Package Subprograms

Subprogram	Description
Executes the Automatic SQL Tuning task immediately (SYS only)
Displays a text report of the automatic tuning task's history
Changes a task parameter value for the daily automatic runs

EXECUTE_AUTO_TUNING_TASK Function & Procedure

This function and procedure executes the Automatic SQL Tuning task (SYS_AUTO_SQL_TUNING_TASK). Both the function and the procedure run in the context of a new task execution. The difference is that the function returns that new execution name. Note that only SYS can invoke this subprogram.

Parameters

Table 28-2 EXECUTE_TUNING_TASK Function & Procedure Parameters

Parameter	Description
execution_name	A name to qualify and identify an execution. If not specified, it is generated by the advisor and returned by function.
execution_params	List of parameters (name, value) for the specified execution. The execution parameters have effect only on the execution for which they are specified. They override the values for the parameters stored in the task (set through the SET_AUTO_TUNING_TASK_PARAMETER Procedures).
execution_desc	A 256-length string describing the execution

Usage Notes

A tuning task can be executed multiple times without having to reset it.

REPORT_AUTO_TUNING_TASK Function

This procedure displays the results of an Automatic SQL Tuning task.

Parameters

Table 28-3 REPORT_TUNING_TASK Function Parameters

Parameter	Description
begin_exec	Name of the beginning task execution to use. Cheat cooking fever apk. If NULL, the report is generated for the most recent task execution.
end_exec	Name of the ending task execution to use. If NULL, the report is generated for the most recent task execution.
type	Type of the report to produce. Possible values are TEXT which produces a text report.
level	Level of detail in the report: BASIC: simple version of the report. Just show info about the actions taken by the advisor. TYPICAL: show information about every statement analyzed, including requests not implemented. ALL: highly detailed report level, also provides annotations about statements skipped over.
section	Section of the report to include: SUMMARY: summary information FINDINGS: tuning findings PLAN: explain plans INFORMATION: general information ERROR: statements with errors ALL: all sections
object_id	Advisor framework object id that represents a single statement to restrict reporting to. NULL for all statements. Only valid for reports that target a single execution.
result_limit	Maximum number of SQL statements to show in the report

Return Values

A CLOB containing the desired report.

SET_AUTO_TUNING_TASK_PARAMETER Procedures

This procedure updates the value of a SQL tuning parameter of type VARCHAR2 or NUMBER as used for the reserved auto tuning task, SYS_AUTO_SQL_TUNING_TASK.

Parameters

Table 28-4 SET_AUTO_TUNING_TASK_PARAMETER Procedure Parameters

Parameter	Description
parameter	Name of the parameter to set. The possible tuning parameters that can be set by this procedure using the parameter in the form VARCHAR2: MODE: tuning scope (comprehensive, limited) USERNAME: username under which the statement is parsed DAYS_TO_EXPIRE: number of days until the task is deleted EXECUTION_DAYS_TO_EXPIRE: number of days until the tasks's executions is deleted (without deleting the task) DEFAULT_EXECUTION_TYPE: the task defaults to this type of execution when none is specified by the EXECUTE_AUTO_TUNING_TASK Function & Procedure. TIME_LIMIT: global time out (seconds) LOCAL_TIME_LIMIT: per-statement time out (seconds) TEST_EXECUTE: FULL/AUTO/OFF. * FULL - test-execute for as much time as necessary, up to the local time limit for the SQL (or the global task time limit if no SQL time limit is set) * AUTO - test-execute for an automatically-chosen time proportional to the tuning time * OFF - do not test-execute BASIC_FILTER: basic filter for SQL tuning set OBJECT_FILTER: object filter for SQL tuning set PLAN_FILTER: plan filter for SQL tuning set (see SELECT_SQLSET for possible values) RANK_MEASURE1: first ranking measure for SQL tuning set RANK_MEASURE2: second possible ranking measure for SQL tuning set RANK_MEASURE3: third possible ranking measure for SQL tuning set RESUME_FILTER: a extra filter for SQL tuning sets besides BASIC_FILTER SQL_LIMIT: maximum number of SQL statements to tune SQL_PERCENTAGE: percentage filter of SQL tuning set statements The following parameters are supported for the automatic tuning task only: ACCEPT_SQL_PROFILES: TRUE/FALSE: whether the task should accept SQL profiles automatically MAX_AUTO_SQL_PROFILES: maximum number of automatic SQL profiles allowed on the system, in sum MAX_SQL_PROFILES_PER_EXEC: maximum number of SQL profiles that can be automatically implemented per execution of the task.
