-- Execute below script if SQL Server is configured with dynamic port number
DECLARE       @portNo   NVARCHAR(10)
 
EXEC   xp_instance_regread
@rootkey    = 'HKEY_LOCAL_MACHINE',
@key        =
'Software\Microsoft\Microsoft SQL Server\MSSQLServer\SuperSocketNetLib\Tcp\IpAll',

Error Fix: Microsoft SQL Server, Error: 14516

Problem: Proxy (1) is not allowed for subsystem “SSIS” and user “Domain\UserName”. Grant permission by calling sp_grant_proxy_to_subsystem or sp_grant_login_to_proxy. (Microsoft SQL Server, Error: 14516)

Solution:
Above error occurs when the user with the minimum permission (i.e. SQLAgentReaderRole and SQLAgentUserRole) or the user is configured as job owner and trying to run the job which is running under the proxy account security context.

You can execute below script to grant permission to the user and fix the error.


EXEC dbo.sp_grant_login_to_proxy
    @login_name = 'Domain\UserName',
    @proxy_name = 'Proxy Name' ;
GO

T-SQL Script to Check if LiteSpeed is installed or not on the server

You can execute below script against the SQL Server instance and check whether LiteSpeed is installed on the server or not.

T-SQL script is checking registry to check the LiteSpeed version value.

declare @regkeyval varchar(20), @value varchar(255), @rc int
exec @rc=master.dbo.xp_regread 
  @rootkey= 'hkey_local_machine',
  @key='software\imceda\sqllitespeed\engine',
  @value_name='version',
  @regkeyval=@value output

set @value =isnull(@value,'-') 

if @value <> '-'
select 
 @@servername as SQLInstanceName
,case serverproperty('IsClustered') when 1 then cast(serverproperty('computernamephysicalnetbios') as varchar)
 else cast(serverproperty('machinename') as varchar)
 end as WindowsServerName
,@value as LiteSpeedVersion 
,'LiteSpeed is installed' as LiteSpeedStautsCheck
else
select 
 @@servername as SQLInstanceName
,case serverproperty('IsClustered') when 1 then cast(serverproperty('computernamephysicalnetbios') as varchar)
 else cast(serverproperty('machinename') as varchar)
 end as WindowsServerName
,'LiteSpeed is not installed' as LiteSpeedStautsCheck

Powershell – To check the Drive and Disk Space Information

To get the disk space details of the server, simply go to command prompt and paste the below script it will give you disk space details.

powershell -command "& {Get-WmiObject -Class Win32_LogicalDisk -Filter 'DriveType = 3' |select PSComputerName, Caption,@{N='Capacity_GB'; E={[math]::Round(($_.Size / 1GB), 2)}},@{N='FreeSpace_GB'; E={[math]::Round(($_.FreeSpace / 1GB), 2)}},@{N='PercentUsed'; E={[math]::Round(((($_.Size - $_.FreeSpace) / $_.Size) * 100), 2) }},@{N='PercentFree'; E={[math]::Round((($_.FreeSpace / $_.Size) * 100), 2) }}}"

Sample Output
Caption : C:
Capacity_GB : 283.44
FreeSpace_GB : 51.48
