You need to know if User1 adds logins to securityadmin server-level audit action group: SERVER_ROLE_MEMBER_CHANGE_GROUP eg: to write messages to the Application Log when users are added to or removed from a fixed server role in Serever01. A Server Audit Specification



Policy Based Management


sample policy location: 
Drive_letter:\Program Files\Microsoft SQL Server\100\Tools\Policies\DatabaseEngine\1033
Drive_letter:\Program Files\Microsoft SQL Server\110\Tools\Policies\DatabaseEngine\1033

import these sample policies (you can delete them later if you don't want to use them) 
from SSMS by navigating to Management, opening up Policy-Based Management , 
right-clicking on "Policies", then selecting "Import Policy". 

eg: a Policy: to prevent users from disabling server audits in Server01

Contained Database


contained database:

execute sp_configure 'contained database authentication', 1
reconfigure

Execute the ALTER DATABASE statement along with CONTAINMENT=PARTIAL.

Execute sp_migrate_user_to_contained for each user


Azure



You plan to migrate the db to azure. 
You verify that all objects are valid for azure sql database. 
You need to ensure that users and logins are migrated to azure. 
What should u do?

* Use the SQL Management Studio to deploy the db to azure.


Blocking Session



sp_who 60  -- show blocking session
sp_who2 60

SQL Server Management Studio 
--> View 
--> Show Extended Event Session Explorer 
--> system_health
--> Events
--> sqlserver.error_reported or sqlserver.xml_deadlock_report

SELECT CAST(xet.target_data AS XML) FROM sys.dm_xe_session_targets xet 
JOIN sys.dm_xe_sessions xe 
ON (xe.address = xet.event_session_address) 
WHERE xe.name = 'system_health';


Q: You administer a Microsoft SQL Server 2012 database. Users report that an application that
accesses the database displays an error, but the error does not provide meaningful information.
No entries are found in the SQL Server log or Windows event logs related to the error. You need to
identify the root cause of the issue by retrieving the error message. What should you do?

A. Create an Extended Events session by using the sqlserver.error_reported event.

CREATE EVENT SESSION [system_health]
ON SERVER
ADD EVENT sqlserver.error_reported(
 ACTION (package0.callstack, sqlserver.session_id, sqlserver.sql_text,

        OR [error]=(802) OR [error]=(8645) 
    OR [error]=(8651) OR [error]=(8657) OR [error]=(8902))))),
ADD EVENT sqlos.scheduler_monitor_non_yielding_ring_buffer_recorded,
ADD EVENT sqlserver.xml_deadlock_report,
ADD EVENT sqlos.wait_info(
 ACTION (package0.callstack, sqlserver.session_id, sqlserver.sql_text)
 WHERE (([duration]>(15000) AND ([wait_type]>(31) AND ([wait_type]>(47)

AND [wait_type]<(100) OR [wait_type]=(107) OR [wait_type]=(113) OR [wait_type]>(174)

        OR [wait_type]=(283) OR [wait_type]=(284)) OR [duration]>(30000) 
        AND [wait_type]<(22))))),
ADD EVENT sqlos.wait_info_external(
 ACTION (package0.callstack, sqlserver.session_id, sqlserver.sql_text)

    OR [wait_type]=(387) OR [wait_type]=(432) OR [wait_type]=(502))))))
ADD TARGET package0.ring_buffer(

WITH (MAX_MEMORY = 4096KB, EVENT_RETENTION_MODE = ALLOW_SINGLE_EVENT_LOSS,
    MAX_DISPATCH_LATENCY = 30 SECONDS, MAX_EVENT_SIZE = 0KB,
