How To Kill All Database Processes On SQL Server
 
06:42
SQl management studio provides lot of facilities to manage SQL processes. The “Activity monitor screen” which will show you some very useful and important information about SQL processes. It will show you all active processes, there status, number of open transactions for each process, the application by which the process is generated, Wait time CPU and memory utilisation, and the host name, means the host or the machine by which the process is initiated etc. If a process is hanging, it will show the process icon with an hour glass. Refresh it several times, sometimes the icon will turn to sleep mode if the process completes its execution. If the icon remains an hour glass, the process may be hanging. Use other info as well to decide if the process is really hanging. If you double click on the process ID it will show the SQL stamen subjected to the execution of the process. If a process is hanging you can identify which application has originated the process, which SQL stamen is hanging and even more from which machine or the host the process is initiated If some application users are complaining about uneven slowness, uneven timeouts etcetera, the reason behind may be one or more processors are hanging. What can you do now? You can restart the SQL server or the service which will disconnect all databases and all applications disturbing all the users. Or otherwise you can take the database to off line and bring it back to online. Or you can disconnect all connections to the database. The disturbance may be lesser than the previous case but still lot of applications and users can be disturbed, especially in an industrial setup. And still you do not know the real reason for the slowness or the malfunctioning as well. So what can you do? Go and examine the processors. Identify exactly which process is hanging. And most probably you will be identifying how and why. So you can find permanent solution. But the immediate solution is you can kill the troubling process or the few. It will solve the issue with minimum disturbance immediately. After identifying the correct process, you can right click on the process ID and click on ‘Kill process’ button. It will kill the selected process. You can kill processors using SQL statements and, using SQL commands you can kill all processors at once as well. Code for Killing Processes Individually USE master go DECLARE @dbname sysname SET @dbname = 'YourDB' EXECUTE ('KILL 53') Code for killing all Processes USE master go DECLARE @dbname sysname SET @dbname = 'YourDB' DECLARE @spid int SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) WHILE @spid IS NOT NULL BEGIN EXECUTE ('KILL ' + @spid) SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) AND spid @spid END

27c3: Techniken zur Identifizierung von Netzwerk-Protokollen (de)
 
44:18
Speaker: Florian Adamsky The presentation will demonstrate techniques that can identify network protocols, which are located in Layer 7 of the OSI model. All the techniques - including deep packet inspection (DPI) - are described technically and assessed critically. The focus of the talk is on the SPID algorithm, the Hjelmvik and John developed. This algorithm inspects the network protocols with statistical characteristics. The results of statistical analysis provide information on how to improve Protocol Obfuscation in the future to ensure that protocols are detected. On the following techniques for the identification of network protocols on the input of content: port numbers, deep packet inspection, machine learning algorithms and the hybrid approach SPID. All techniques must be weighed according to the following requirements. First, what protocols are detected in near real time. Second, a robust and reliable detection of possible protocols to be possible. And Third, the technology to run low-power and low-cost hardware. After considering the technical details of the SPID algorithm explained and illuminated selected statistical characteristics. These form the basis of the following to improve Protocol Obfuscation. Finally, different evaluation results are presented. (via google translate) For more information visit:http://bit.ly/27c3_information To download the video visit: http://bit.ly/27c3_videos

Difference between blocking and deadlocking
 
06:52
deadlock vs blocking sql server In this video we will discuss the difference between blocking and deadlocking. This is one of the common SQL Server interview question. Let us understand the difference with an example. SQL Script to create the tables and populate them with test data Create table TableA ( Id int identity primary key, Name nvarchar(50) ) Go Insert into TableA values ('Mark') Go Create table TableB ( Id int identity primary key, Name nvarchar(50) ) Go Insert into TableB values ('Mary') Go Blocking : Occurs if a transaction tries to acquire an incompatible lock on a resource that another transaction has already locked. The blocked transaction remains blocked until the blocking transaction releases the lock. Example : Open 2 instances of SQL Server Management studio. From the first window execute Transaction 1 code and from the second window execute Transaction 2 code. Notice that Transaction 2 is blocked by Transaction 1. Transaction 2 is allowed to move forward only when Transaction 1 completes. --Transaction 1 Begin Tran Update TableA set Name='Mark Transaction 1' where Id = 1 Waitfor Delay '00:00:10' Commit Transaction --Transaction 2 Begin Tran Update TableA set Name='Mark Transaction 2' where Id = 1 Commit Transaction Deadlock : Occurs when two or more transactions have a resource locked, and each transaction requests a lock on the resource that another transaction has already locked. Neither of the transactions here can move forward, as each one is waiting for the other to release the lock. So in this case, SQL Server intervenes and ends the deadlock by cancelling one of the transactions, so the other transaction can move forward. Example : Open 2 instances of SQL Server Management studio. From the first window execute Transaction 1 code and from the second window execute Transaction 2 code. Notice that there is a deadlock between Transaction 1 and Transaction 2. -- Transaction 1 Begin Tran Update TableA Set Name = 'Mark Transaction 1' where Id = 1 -- From Transaction 2 window execute the first update statement Update TableB Set Name = 'Mary Transaction 1' where Id = 1 -- From Transaction 2 window execute the second update statement Commit Transaction -- Transaction 2 Begin Tran Update TableB Set Name = 'Mark Transaction 2' where Id = 1 -- From Transaction 1 window execute the second update statement Update TableA Set Name = 'Mary Transaction 2' where Id = 1 -- After a few seconds notice that one of the transactions complete -- successfully while the other transaction is made the deadlock victim Commit Transaction Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/difference-between-blocking-and.html

How to Get locked Objects in SQL Server
 
08:38
Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg Generally, There are two ways to get what are the objects are Locked. First way with SP_LOCK, We can get the Locked Object details in a Particular Session Or SQL Server Engine. Second way is Used with DMV, Sys.dm_trans_lock it returns the Locked Objects with Some more data's when compared to SP_LOCK. Both are explained with Simplest Example in this Video. To Get Locked Objects ----------------------------------- Select S2.host_name, S1.Resource_type, (Case when S1.resource_type IN ('RID', 'PAGE') then s5.name when S1.resource_type IN ('DATABASE') then s6.name else S4.Name end) Name, S1.resource_associated_entity_id, S1.request_mode, S1.request_type, S1.request_status, S1.request_session_id, ISNULL(S3.rows , 0) Rows From Sys.dm_tran_locks S1 Inner join Sys.dm_exec_sessions S2 on S1.request_session_id = S2.session_id left join sys.partitions S3 on S1.resource_associated_entity_id = S3.partition_id left join sys.objects s5 on s3.object_id = S5.object_id left join sys.objects S4 on (case when S1.resource_type = 'OBJECT' THEN S1.resource_associated_entity_id else null End) = S4.object_id left join sys.sysdatabases s6 on S1.resource_database_id = s6.dbid Where S1.resource_database_id = DB_ID() With Requested SQL Server Statement ------------------------------------------------------------- Select S1.*, S2.text From sys.sysprocesses S1 cross apply sys.dm_exec_sql_text (Sql_handle) S2 Where spID = SessionID

Comprendre l'escalade de verrous dans SQL Server
 
05:07
Le verrouillage est un élément essentiel de la gestion des transactions dans SQL Server. Il garantit l’isolation de la transaction et la protection des données lors des accès concurrent. Dans cette vidéo, j’aborde le verrouillage des données sous un aspect précis : l’escalade des verrous. Lorsque le moteur de stockage de SQL Server doit poser beaucoup de verrous, il escalade le verrouillage sur les structures contenantes, les pages et la table elle-même. Nous voyons pratiquement comment SQL Server escalade les verrous. Suivez la série des astuces SQL Server. Deux astuces par semaine.

Accidental DBA - Don't Let Your Database Be a Black Box
 
43:12
Learn more about the SolarWinds THWACK community here http://bit.ly/TC2016_AccidentalDBA. To many users (and even some SysAdmins) a database is a black box. Queries go in, and data comes out. But, many new (or accidental) DBAs may lack the advanced skills necessary for critical performance tuning and troubleshooting, which will keep the users (and SysAdmins) happy. This session helps everyone to understand what is happening inside of the black box, how to diagnose performance issues, and what actions you can take to fix common database performance problems.
