hotfixJust a quick heads up on a new KB article we published today:

=====

Symptoms

Removing an old product connector from System Center Operations Manager 2007 (OpsMgr 2007) may be necessary if the product connector is no longer used in the environment. There is no Delete option in admin console UI for product connectors so the script below can be used to achieve the desired results.

Resolution

Use the following Powershell script to remove the product connector:

Note Internal Connectors should not be removed, also be sure to backup both the Operational DB and the Data Warehouse before running this. Also save the below as DeleteConnector.ps1

param(
[String] $connectorName,
[String] $mgName="localhost"
)
Import-Module OperationsManager
$mg = new-object Microsoft.EnterpriseManagement.ManagementGroup $mgName
New-ManagementGroupConnection -ComputerName $mgName

##########################################################################################
# Configures a connector with the specified name.
##########################################################################################
function New-Connector([String] $name)
{
$connectorForTest = $null;
$connectorForTest = Get-Connector | where {$_.Name -eq $name}
if ($connectorForTest -eq $null)
{
$admin = $mg.ConnectorFramework
$testConnector = New-Object Microsoft.EnterpriseManagement.ConnectorFramework.ConnectorInfo
$testConnector.Name = $name
$testConnector.Description = "${name} Description"
$testConnector.DiscoveryDataIsManaged = $false
$connectorForTest = $admin.Setup($testConnector)
$connectorForTest.Initialize();
}
return $connectorForTest
}


##########################################################################################
# Removes a connector with the specified name.
##########################################################################################
function Remove-Connector([String] $name)
{
$admin = $mg.ConnectorFramework
$testConnector = Get-Connector -Name $name

foreach($alert in $testConnector.GetMonitoringAlerts())
{
$alert.ConnectorId = $null;
$alert.Update("Delete Connector");
}

if($testConnector.Initialized)
{
$testConnector.Uninitialize()
}
$connectorIdForTest = $admin.Cleanup($testConnector)
}

##########################################################################################
# Delete a connector's Subscription
##########################################################################################
function Delete-Subscription([String] $name)
{
$connector = Get-Connector | where {$_.Name -eq $name}
$subs = $mg.ConnectorFramework.GetConnectorSubscriptions()
$admin = $mg.ConnectorFramework
foreach($sub in $subs)
{
if($sub.MonitoringConnectorId -eq $connector.id)
{
$admin.DeleteConnectorSubscription($admin.GetConnectorSubscription($sub.Id))
}
}
}

#New-Connector $connectorName
write-host "Delete-Subscription"
Delete-Subscription $connectorName
write-host "Remove-Connector"
Remove-Connector $connectorName
