과제 10
sql60152867의 모든 데이터베이스에 인덱스가 자동으로 생성되도록 해야 합니다. SQL Server Management Studio와 Azure 포털을 사용해야 할 수도 있습니다.
Correct Answer:
See the explanation part for the complete Solution.
Explanation:
Enable Automatic tuning at the server level and turn Create Index to On.
Microsoft states that Azure SQL Database automatic tuning can create indexes automatically, verify performance improvement, and roll back changes if performance regresses. Server-level automatic tuning settings are applied to all databases on the server by default, unless a database has its own override.
Azure Portal Method - Recommended for Simulation
Step 1: Open the SQL logical server
Sign in to the Azure portal.
Search for SQL servers.
Open:
sql60152867
Do not open only db1. The task says all databases on sql60152867, so configure this at the server level.
Step 2: Open Automatic tuning
In the SQL server left menu:
Go to Intelligent Performance.
Select Automatic tuning.
Microsoft's documented path is to open the Azure SQL server in the portal and select Automatic tuning from the menu.
Step 3: Enable automatic index creation
On the Automatic tuning page, configure:
Setting
Value
Create index
On
Drop index
Leave unchanged unless required
Force last good plan
Leave unchanged unless required
The only required setting is:
Create index = On
Do not confuse this with Drop index. The task only asks to ensure indexes are created automatically.
Step 4: Apply the setting
Select Apply or Save.
Wait for the portal confirmation.
The setting is now configured at the SQL logical server level.
Important Database Inheritance Check
This is the part people miss.
Server-level automatic tuning applies to databases that inherit from the server. Microsoft states that individual databases can override server-level automatic tuning settings. Therefore, if the simulation shows any database with custom automatic tuning settings, set that database to Inherit from server or manually set Create index = On for that database.
For each database, the correct inherited state should be:
Automatic tuning = Inherit from server
Create index = Inherited / On
If a database is set to:
Custom
Create index = Off
then the server-level setting might not affect that database. Fix it.
Database-Level T-SQL Method
Use this only if the portal is unavailable or you need to correct a specific database override.
Connect to each database and run:
ALTER DATABASE CURRENT
SET AUTOMATIC_TUNING (
CREATE_INDEX = ON
);
Microsoft documents this exact syntax for enabling the CREATE_INDEX automatic tuning option by T-SQL on an individual Azure SQL Database.
To make an individual database inherit server settings, run:
ALTER DATABASE CURRENT
SET AUTOMATIC_TUNING = INHERIT;
But this must be executed inside each database, not from master as a single server-wide T-SQL command.
Verification with T-SQL
Connect to a database and run:
SELECT
name,
desired_state_desc,
actual_state_desc
FROM sys.database_automatic_tuning_options
WHERE name = ' CREATE_INDEX ' ;
Expected result:
name CREATE_INDEX
desired_state_desc ON or DEFAULT
actual_state_desc ON
If desired_state_desc is DEFAULT, that usually means the database is inheriting the server-level setting. The key result is:
actual_state_desc = ON
SSMS Clarification
SSMS can be used to verify or configure the setting per database using T-SQL, but it is not the best tool for the requirement as written.
Because the task says:
all the databases on sql60152867
the correct primary method is:
Azure portal > SQL server > Automatic tuning > Create index = On
Final Exam-Lab Action
Configure this:
SQL server: sql60152867
Automatic tuning
Create index: On
Apply
Then verify databases are inheriting the server setting or have CREATE_INDEX = ON.
That completes the task.
