Hello everyone, this time I am going to show the "Server Alias".
I have been asked by one of my customers to write down a PowerShell script to add an SQL Alias as part of an automatic installation.
The Alias is stored in the registry at this path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo
The alias is configured via the configuration manager.
An alias is a name that can be used instead of a connection.
It holds inside some elements of the connection string and can be used from each and every client application. One of its advantages is that it contains all the connection details - protocol, ports and named pipes. It even allows you to redirect a connection to a remote server.
Here is the script:
## Setting the Alias name, Server name and setting the port number## Adding an extension to the alias name _ALDB Customer Request $ServerName = Get-Content Env:Computername$AliasName = $ServerName+"_ALDB"
$SN$AliasName$PortNum = 1111## The Aliase is stord in the registry here i'm seting the ## REG path for the Alias 32 & 64$Bit32 = "HKLM:\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo"
$bit64 = "HKLM:\SOFTWARE\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo"
## chect if the ConnectTo SubFolder ## exist in the registry if not it will create it.If((Test-Path -Path $Bit32)-ne $true)
{$writable = $true$key = (get-item HKLM:\).OpenSubKey("SOFTWARE\Microsoft\MSSQLServer\Client", $writable).CreateSubKey("ConnectTo")
}
If((Test-Path -Path $Bit64)-ne $true)
{ $key = (get-item HKLM:\).OpenSubKey("SOFTWARE\Wow6432Node\Microsoft\MSSQLServer\Client", $writable).CreateSubKey("ConnectTo")}
## Create the TCPAlias$TCPAliasName="DBMSSCON,"+$ServerName+","+$PortNum
New-ItemProperty -Path $Bit32 -Name $AliasName -PropertyType string -Value $TCPAliasName
New-ItemProperty -Path $Bit64 -Name $AliasName -PropertyType string -Value $TCPAliasName
