Small Framework to load sql scripts simultaniously to several Servers

I use the following framework to run scripts calling sqlcmd simultaneously as PowerShell jobs during some MsBuild Task. My Buildagents are running Server 2003 and there are some linitations cf. StackOverflow.

But just calling sqlcmd works fine. In fact I'm dropping and recreating my test databases and running a lot of sql scripts completly within such background jobs. I didn't try it with the Oracle part using sqlplus which I run in the main script and after whose termination I wait for jobs to terminate in time or terminate them. 

$workdir = Split-Path $MyInvocation.MyCommand.Path            
$logdir = 'C:\temp\log'            
$server1 = 'my_sql2008'            
$server2 = 'my_sql2005'            
$datbase = 'PowerShellTest'            
            
$cmd1 = [scriptblock]::Create(". $workdir\script_containing_function_for_background_job.ps1
Some_function -server $server1 -database $datbase $logdir -asJob" )            
            
                
$cmd1 = [scriptblock]::Create(". $workdir\script_containing_function_for_background_job.ps1
Some_function -server $server2 -database $datbase $logdir -asJob" )            
            
            
"...Starting the background jobs"            
$SQLJobStartTime = Get-date            
$jnr1 = (Start-Job -ScriptBlock $cmd1).Id            
$jnr2 = (Start-Job -ScriptBlock $cmd2).Id
