An easier way to deal with sp_who2

As a DBA sp_who2 is a stored procedure I use on a daily basis, however, it is not possible to filter its output or manipulate it in any way.

To help with this I use the simple script below as a snippet that exports the output of sp_who2 to a temporary table where I can play with the results much easier.

-- Export sp_who2 to temp table
IF EXISTS (SELECT 1 FROM tempdb..sysobjects WHERE id=OBJECT_ID('tempdb..#spwho2')) DROP TABLE #spwho2
CREATE TABLE #spwho2(
    [SPID] INT
    ,[Status] VARCHAR(30)
    ,[Login] VARCHAR(50)
    ,[HostName] VARCHAR(30)
    ,[BlkBy] VARCHAR(30)
    ,[DBName] VARCHAR(30)
    ,[Command] VARCHAR(50)
    ,[CPUTime] INT
    ,[DiskIO] INT
    ,[LastBatch] VARCHAR(30)
    ,[ProgramName] VARCHAR(100)
    ,[SPID2] INT
    ,[RequestID] INT
)
INSERT INTO #spwho2
EXEC sp_who2

SELECT [SPID]
       ,[Status]
       ,[Login]
       ,[HostName]
       ,[BlkBy]
       ,[DBName]
       ,[Command]
       ,[CPUTime]
       ,[DiskIO]
       ,[LastBatch]
       ,[ProgramName]
       ,[SPID2]
       ,[RequestID]
FROM #spwho2

How to configure the SSAS service to use a Domain Account

NB Updating SPNs in AD is not for the faint hearted plus I got inconsistent results from different servers. Do so at your own risk! If you need the SSAS account on a SQL Server to use a domain account rather than the local “virtual” account “NT Service\MSSQLServerOLAPService”. You may think you just give the account login permissions to the server, perhaps give it sysadmin SQL permissions too. However, if you try and connect to SSAS  remotely  you may get this error: Authentication failed. (Microsoft.AnalysisService.AdomdClient) The target principal name is incorrect (Microsoft.AnalysisService.AdomdClient) From Microsoft: “A Service Principle Name (SPN) uniquely identifies a service instance in an Active Directory domain when Kerberos is used to mutually authenticate client and service identities. An SPN is associated with the logon account under which the service instance runs. For client applications connecting to Analysis Services via Kerberos authentication, th

How to move the Microsoft Assessment and Planning Toolkit (MAP) database to a different drive

The Microsoft Assessment and Planning Toolkit (MAP) is a very useful tool for scanning your network to find instances of SQL Server plus all manner of detailed information about the installed product, OS and hardware it sits on. <Click image to enbiggen> There is an issue with it the database it uses to store the data it collects, however. Assuming you don't have an instance called MAPS on your server, the product will install using LocalDB (a cut down version of SQL Server Express) and puts the databases on your C: drive. If you then scan a large network you could easily expand the database to 10GB which may cause issues on a server when that drive is often one of the smallest. However, there is a simple solution: connect to LocalDB using Management Studio, detach the databases, move to a different drive, set permissions on the new location if required and reattach the database. How do you connect to LocalDB? Here you go: Connect to (localdb)\MAPTOOLKIT The

SAN performance testing using SQLIO

Introduction This document describes how to use Microsoft’s SQLIO to test disk/SAN performance. It is biased towards SQL Server – which uses primarily 64KB and 8KB data pages so I am running the tests using those cluster sizes, however, other sizes can be specified.  Download SQLIO from https://www.microsoft.com/en-gb/download/details.aspx?id=20163   SQLIO is a command line tool with no GUI so you need to open a command prompt at  C:\Program Files (x86)\SQLIO  after you have installed it. Configuration First of all edit param.txt so that you create the test file we will be using. The file needs to be bigger than the combined RAID and on-board disk caches. In this case we are using a 50GB file. The “ 2”  refers to the number of threads to use when testing, you don’t need to change this now. The “ 0x0”  value indicates that all CPUs should be used, which you probably don’t want to change either, “ #”  is a comment. The only part you may want to change is 51200 (50GB) a
