Windows server and Oracle Java updates

[Domingues, Michael D]

It's baked right in to CMD.exe, and they've provided no PowerShell alternative, so if you're pushing at the PowerShell layer, you could use something like this. Yes, the /S /Q syntax on the second function looks odd, but it achieves the desired behavior of only taking out the link.


function New-Symlink
{
    [CmdletBinding()]
    param([string]$Link, [string]$Target);
    Start-Process-Custom -FilePath "cmd.exe" -ArgumentList "/C mklink /D `"$Link`" `"$Target`"";
}

function Remove-Symlink
{
    [CmdletBinding()]
    param([string]$Link);
    Start-Process-Custom -FilePath "cmd.exe" -ArgumentList "/C rmdir /S /Q `"$Link`"";
}


Also relevant for those trying to automate (or at least script) their Oracle Java installs on Windows is a way to programatically check the Oracle License Agreement:


function Get-OracleDownload
{
    param([URI]$URI, [string]$OutFile);

    $session = New-Object Microsoft.PowerShell.Commands.WebRequestSession;

    $oracle_cookie = New-Object System.Net.Cookie ;

    $oracle_cookie.Name = "oraclelicense";
    $oracle_cookie.Value = "accept-securebackup-cookie";
    $oracle_cookie.Domain = ".oracle.com";

    $session.Cookies.Add($oracle_cookie);

    Invoke-WebRequest -Uri $URI -WebSession $session -TimeoutSec 900 -OutFile $OutFile -ErrorAction Stop;

    return $OutFile;
}

Windows supports symlinks too.
