Blocking
Blocking
user1 running a command on table1 which is
still executing at the same time other user try to read/update the data from/to
same table then user1 query will block the user2 Query.
Step1:
Find the Blocking
There are number of ways to find out
the details of the system processes IDs (spids) involved in blocking.
1. sp_who2 System Stored Procedure
2.
sys.dm_exec_requests DMV
3.
sys.sysprocesses
4.
Sys.dm_os_waiting_tasks
5.
SQL Server Management Studio Activity
Monitor
6.
SQL Server Management Studio Reports
7.
SQL Server Profiler
1.sp_who2 System
Stored Procedure
The sp_who2 system stored procedure
provides information about the current SQL Server processes with the associated
SPID, status,login,Hostname,BlkBy,DBName,Command,CPU time, etc. The information
returned can be filtered to return only the active processes by using the
‘active' parameter.
Below is some sample code and a
screen shot with showing process 54 being blocked by process 53.
1.USE Master
Go
Sp_Who2
Go
2.USE Master
Go
Sp_Who2 active
Go
2. sys.dm_exec_requests DMV
The sys.dm_exec_requests DMV provides details
on all of the processes running in SQL Server. With the WHERE condition listed
below, only blocked processes will be returned.
Use master
Go
select * from
sys.dm_exec_requests
where blocking_session_id<>0
3. sys.sysprocesses
The sys.sysprocesses provides details on all of
the processes running in SQL Server. With the WHERE condition listed below, only
blocked processes will be returned.
Use master
GO
Select * from sys.sysprocesses where
blocked<>0
4.sys.dm_os_waiting_tasks
DMV
The sys.dm_os_waiting_tasks DMV
returns information about the tasks that are waiting on resources.
USE Master
GO
SELECT session_id, wait_duration_ms, wait_type, blocking_session_id
FROM sys.dm_os_waiting_tasks
WHERE blocking_session_id <> 0
GO
5.SQL Server
Management Studio Activity Monitor
It is easy procedure to do find the
blocking from SSMS.
Open SSMS->Connect instance->Right click on instance-> select 'Activity Monitor'->Processes
OR
6.SQL Server
Management Studio Reports
We can monitor the blocking on
standard reports.
Open SSMS->Connect
instance->Right click on instance-> Reports -> Standard Reports-> Activity -
All Blocking Transactions.
7.SQL Server
Profiler
To capture blocking related data on a
continuous basis, one option is to run SQL Server Profiler and save the data to
a table or file for analysis purposes. In order to configure Profiler to
capture blocking related data, execute Profiler, configure the general
properties. In addition, be sure to configure the 'blocked process threshold'
before you start Profiler using this code:
sp_configure 'show advanced options', 1
GO
RECONFIGURE
GO
sp_configure 'blocked process threshold', 20
GO
RECONFIGURE
GO
Menu Bar->Tools->SQL
Profiler->Connect the Instance->Select use template as
TSQL-Lock->click on column filter->Select Database->Give the database
name->ok->Run
Note: Don’t do this process in
business hours. It causes a performance issue. Without change we can’t run the
profiler.
Step2:INPUTBUFFER
Find the command which is running under
SPID by using DBCCDBCC INPUTBUFFER(53)
Step3:KILL
SPID
Kill the transaction by using below
command
KILL 53
Note:
1.If select then kill the SPID ( Select
command is not modify the data)
2. There is any other command part of the
blocking then we can take the user/application team approval then we will kill
it
