DBA Scenario 1: How to handle 100% CPU Utilization

Hi guys! Today we shall discuss the hot topic how to handle 100% CPU Utilization. DBA face this kind of situation often in their daily life. Some time it is must to solve this situation in production environment as this will hamper the business activity in terms of transactions and money.

The methods we are about to discuss, help only if SQL server is the culprit, You need to first identify whether SQL is consuming all memory resources, then only you need to apply these methods otherwise it will not help you-

I shall cover two methods; both methods are not same and can’t be used at same time. Their aim is same to lower the memory usage but they are applied over different scenario.

Before begin, I want to discuss a myth that is, mostly it is assumed that longer running queries are problem, but it is not true all the time, yes it may cause problem but small concurrent running queries having maximum worker time or maximum execution count can also be a problem. For example a query which is executing before 1 sec can’t be a problem. But the same query if executed 1 lac time concurrently (at the same time) can cause issue.

As per my experience, mostly select queries are the culprit and create such situation so that sql server starts consuming 100 % of memory resources. You can use task manager or resource monitor to find the CPU usage.

Method 1 :

It is a traditional approach, mostly used by DBAs.  Whenever this kind of situation arises, you need to first check for the intense processes running on the server. For this you need to continuously execute one procedure sp_who2 and monitor which spid is increasing gradually, then you need to identify what is going on that session for that use dbcc inputbuffer(<spid>), if it is select query you can kill it but you should not kill transaction and queries having insert update delete on sql tables.

sp_who2

dbcc inputbuffer(<spid>)

kill <spid>

Note: You need to look for spid greater than 50 because less than 50 spids are used by Sql server for its internal working.

Method 2 :

It is more granular approach to optimize the query. In this approach you need to use few DMV’s. Sql server increases the execution_count for same query, if the definition of the query changes new plan is created. So you need to find out the queries having maximum exeution_count and maximum total_worker_time. When you find the record you will get the query plan, which you need to copy and paste to another dmv that is sys.dm_exec_query_stats.

Select * from sys.dm_exec_query_stats order by execution_count desc

Select * from sys.dm_exec_query_stats order by total_worker_time desc

Select * from sys.dm_exec_query_plan(<plan_handle>)

So from above query we will get the execution plan and from there we can view xml view of query and find parameters for the query. After getting queries you can apply sargable rules, these rules are used to optimize queries.

This is how you can trace costly queries and handle 100% CPU Utilization

SSRS - Download all Report files Or Single (RDL) from Report Server

Hi friends! Today my manager asked me to download all reports from Report Server and check in to TFS.

There were plenty of reports almost 1000, so it is difficult to download one by one. I thought this kind of problem come to most of the DBAs so decided to write this blog, I found same script on google and modified it-

Prerequisites & Notes :

1. xp_cmdshell should be enabled. (Part 1)

2. SQL Engine Account should proper write permission on Output Folder where you will get all your reports  

3. Please read comments before execution and follow (Part 2)

4. Change the Report Server database on the query

Part 1 : Enable xp_cmdshell 

EXEC sp_configure 'show advanced options', 1
GO
RECONFIGURE
GO
EXEC sp_configure 'xp_cmdshell', 1
GO
RECONFIGURE
GO
EXEC sp_configure 'show advanced options', 0
GO
RECONFIGURE
GO

Part 2 : Script Implementation

/*

If you want all reports in output folder whether they were published in different folders
in SSRS Report Server then put Null else define folder name
eg: DECLARE @ReportFolderPath AS VARCHAR(500) ='/Folder1/Folder2/'

 

*/

DECLARE @ReportFolderPath AS VARCHAR(500) = null 
/*
If you want some specific report then put its name else put Null
eg: DECLARE @ReportName AS VARCHAR(500) = 'Bill'
*/
DECLARE @ReportName AS VARCHAR(500) = null
/* 
This is the output folder where reports will be generated. Make sure Sql Server Engine Account 
has proper permission on this
*/
DECLARE @OutputFolderLocation AS VARCHAR(500) = 'C:\ReportFolder\'
--To check Folder path
SET @OutputFolderLocation = REPLACE(@OutputFolderLocation,'\','/')
/*
This for bcp access to sql server. If you want to access through sql login use
eg : DECLARE @BCPComponents VARCHAR(1000)='-S"MachineName\SQL2012" -U"SA" -P"Pa$$word"'
or If you want from windows account having permission on sql then
eg : DECLARE @BCPComponents VARCHAR(1000)='-S"1MachineName\SQL2012"'
else null
*/
DECLARE @BCPComponents VARCHAR(1000)= null
DECLARE @SqlQuery AS NVARCHAR(MAX)

IF LTRIM(RTRIM(ISNULL(@OutputFolderLocation,''))) = ''
BEGIN
  SELECT 'Access denied!!!'
END
ELSE

Monitor Database Size Location through query and mailer

Hi friends! One of my friend asked me to help him creating a mailer that gives information about all databases of a server. I tried and created this-

----------------------------------------------------------------------

Use master
Go

    LogicalName sysname,
    physical_name varchar(500),
    size decimal (18,2),
    FreeSpace decimal (18,2),
 [DBState] varchar(500)
)   
Exec sp_msforeachdb '

Insert Into #temp (DatabaseName, LogicalName, physical_name, Size, FreeSpace,[DBState])
    Select DB_NAME() AS [DatabaseName], Name as LogicalName,  physical_name,
    Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2)) as nvarchar) Size,

Monitor Windows Server having SQL Services Agent Services Reporting Services

Hi guys! Yesterday my boss asked me to build a tool to monitor Windows servers and Sql server services. I searched on Google and find few codes, i modified the code changed powershell concept and made below code.

In this post I shall tell you about how you monitor your all servers. The only thing you need is SQL Server which runs with an account having admin privilege on the network, or you can monitor those systems, the account having admin rights.

Lets start-

Create a database and two tables-

----------------------------------------------------------------------

Use master
Go
Create Database DBAMonitor
GO
Use DBAMonitor
GO 

CREATE TABLE [dbo].[tbl_ServerInfo](
 [Id] [int] identity(1,1) Not NULL,
 [WindowsServerName] [varchar](100) Not NULL,
 [SQLinstanceName] [varchar](100)  NULL
) ON [PRIMARY]

CREATE TABLE [dbo].[tbl_ServiceInfo](
 [SQLServiceName] [varchar](500) NULL,
 [servicestatus] [varchar](100) NULL,
 [windowservername] [varchar](500) NULL,
 [startmode] [varchar](100) NULL,
 [UpdateDate] [datetime] NULL DEFAULT GETDATE(),
 [startname] [varchar](1000) NULL,
 [InstanceName] [varchar](1000) NULL,
 [ServerID] INT NULL
) ON [PRIMARY]

----------------------------------------------------------------------

Please add your server details on tbl_serverInfo you want to monitor-

----------------------------------------------------------------------

--For example

insert into [tbl_ServerInfo](windowsServerName,SQLinstanceName) values ('Proddb','Dashboard')
insert into [tbl_ServerInfo](windowsServerName,SQLinstanceName) values ('192.168.0.512','sql2008r2')
insert into [tbl_ServerInfo](windowsServerName,SQLinstanceName) values ('192.168.0.500','')
insert into [tbl_ServerInfo](windowsServerName,SQLinstanceName) values ('192.168.0.510','')

--Checking details

----------------------------------------------------------------------

Now we need to run below script, but make sure xp_cmdshell is enabled. To enable it, please run below code-

----------------------------------------------------------------------

sp_configure 'Show Advanced Options',1
go
reconfigure
go
sp_configure 'xp_cmdshell',1
go   
reconfigure
go

----------------------------------------------------------------------

Now run the script and look the power-

----------------------------------------------------------------------

From DBAMonitor..[tbl_ServerInfo] srvr
Left Join DBAMonitor..[tbl_ServiceInfo] sevi on srvr.ID=sevi.Serverid

---------------------------------------------------------

For better results, Create a job and run the above script from sql agent.

You can also create mailer for same to notify.

The below code is to notify if any service is stopped or any server is down.

Drop And Recreate all indexes on all tables of a database :

How to use :

First execute both scripts (on SSMS) on your database and save the result. It will generate drop index  and create index for all tables on database.

After doing this, please execute drop indexes result and then execute create index result.

Please verify the result.
