Installing the Oracle client OleDB provider on the watcher node

The watcher node can be any machine containing the SCOM agent.
It’s important to have the right Oracle client version (I used version 11), for 32bit versions use the 32bit Oracle client. For 64bit use the 64bit Oracle client version. Both are available on the Oracle website. If you don’t use the correct version (e.g. 32bit on 64bit) you might get “Class unknown” errors within SCOM.
Start the Oracle installation, on the first step in the installation wizard choose “Custom” and click “Next”

On the next page select your favorite language(s), then pick a location for the Oracle client (beware it’s huge, even for one component)
In the “Available Product Components” step select the following component (Oracle Provider for OLEDB:

Finish the installation.

Note:you also need to setup Oracle’s tnsnames file, this is beyond the scope of this article. Consult your Oracle DBA.

Test the Oracle client OleDB provider, and connection to the database

To test a OleDB connection, you can use a UDL file. This is a connection file, which launches a wizard once you click it.
Use the following steps to create an UDL file:

1. Make sure in Windows Explorer, Tools->Folder Options, View Tab, that “Hide file extensions for known file types” is not checked.
2. Right click on Windows desktop, and select New->Text File.
3. Name the file “Test.udl”. The icon for the file should now be the special “UDL” icon.
4. Double click the file to open the Data Links dialog.
5. Click on the “Provider” tab. Select “Oracle Provider for OLE DB”.

6. Click on the “Connection” tab. In the first dialog box (server name) type the oracle service ID (the name defined in the tnsnames file)
7. Specify the credentials (username and password) in the same dialog box.
8. Click “Test Connection”, you should now see this embracing message :-)

Add OleDB monitoring in SCOM

The next step is to add monitoring to SCOM. Start the SCOM operations manager console and click on “Authoring”.
Within this view, click on “Add Monitoring Wizard” on the left hand side.
To add an OleDB watcher, use the following steps:

1. In the “Select Monitoring Type” step select “OLE DB Data Source”, click “Next”
2. Within the general properties step specify a name for the monitor and choose a Management Pack for your custom monitoring (Microsoft recommends not to use the default management pack here, so create a new one!)
3. In the Connection String dialog click on the “Build…” button. Choose any random Provider (we will change the connection string later on) enter a random computer name and database as well. Make sure you check: “Use Simple Authentication RunAs Profile created for this OLE DB data source transaction”, this is important.

4. Enter Query performance thresholds, if this is required.
5. Within the “Watcher Nodes” step, select the machine on which we installed the Oracle client.
6. Finish the wizard.

You should now end up with an OleDB Data Source within SCOM.
Open the data source and navigate to the “Connection String” tab.
Change the connection string in to the following format:

Provider=OraOLEDB.Oracle;Data Source=TEST;User Id=$RunAs[Name="OleDbCheck_b7035c5b5d6149b684df79089e99dc07.SimpleAuthenticationAccount"]/UserName$;Password=$RunAs[Name="OleDbCheck_b7035c5b5d6149b684df79089e99dc07.SimpleAuthenticationAccount"]/Password$

Replace the RunAs variables with the ones generated by the wizard. The data source is the Oracle SID, the same you used to test before. The provider name is the short (internal) name for the Oracle Provider for OLEDB.
Save the OLEDB Data Source.

Add associated runas user profiles

If you checked the “Use Simple Authentication RunAs Profile created for this OLE DB data source transaction” during the wizard you should end up with a preset RunAs profile for this monitor. You can find it under Administration->Run As Configuration->Profiles in the operations manager console.

Double click this “simple authentication” RunAs profile.

To add a “Run As Account” follow the following steps:

1. In the “Run As Profile Wizard” click the “Run As Accounts” tab.
2. Click on the “Add…” button to add an account.
3. Click on “New…”, the “Create Run As Account Wizard” should now start. Skip the introduction.
4. On the general properties page, select the run as account type. Set this to Simple Authentication and specify a display name.

5. On the credentials tab specify the account name and password.
6. Select a distribution security option, based on your preference. I used the More Secure option (you need to reopen the account under the accounts pane to distribute it to your watcher node)
7. Finish the “Create Run As Account Wizard”
8. Click “OK” and finish the “Run As Profile Wizard”

You have now configured the Run As profile.
To see the result of all this work, open the “OLE DB Data Source State” view within the monitoring pane. This is located underneath the “Synthetic Transaction” folder.
This could take a while! (It took about 15 minutes in my environment)

Special thanks to Joel Bennett’s SharpSSH wrapper for PowerShell (located here: http://huddledmasses.org/scriptable-ssh-from-powershell/) which I used to automate the command line commands for the HP WSEM.
This shows the great power of PowerShell for automating virtually anything!

This happened after the server (suddenly) ran out of free disk space. It turned out that all color settings where reset to “0″ (black), the registry showed the following color values:

The fix for this was easy, I took the color schema settings from a working 2003 server and inserted them remotely from my workstation. The color schema settings are located under the following registry key: HKEY_USERS\.DEFAULT\Control Panel\Colors

Now, about my lab environment:

I have setup several virtual machines in my lab environment, this blog post will focus on the machines used for SCSM.
Please note that you can also install service manager on one machine but this rules out the ability to use reporting! The deployment scenario used in this blog post is described here: http://technet.microsoft.com/en-us/library/ff460945.aspx

Machine 1:

This is the domain controller for my test lab, nothing fancy.. but required for SCSM.

Machine 2:

This machine is the datawarehouse for SCSM. This machine also includes a SQL Server 2008 installation.

Machine 3:

This machine is the service manager management server.

SCSM Machine 1: datawarehouse machine.

• Start by installing Windows 2008/2008 R2 (doh)
• Make you install recent updates and service packs.
• You must install the Authorization Manager Hotfix, which is available for request here: http://support.microsoft.com/Default.aspx?kbid=975332 For Windows 2008 I had to download the Vista version of the patch (!)
• Install SQL Server 2008, select the following components during setup:- Database engine services, including full text search (this is a requirement)
  - Reporting services
  - Management Tools, not required but might come handy
• After installing install service pack 1 for SQL Server 2008, this is a requirement.
• You can now install service manager’s data warehouse.

SCSM Machine 2: service manager management server.

• Start by installing Windows 2008/2008 R2 (doh)
• Make you install recent updates and service packs.
• You must install the Authorization Manager Hotfix, which is available for request here: http://support.microsoft.com/Default.aspx?kbid=975332 For Windows 2008 I had to download the Vista version of the patch (!)
• Install Microsoft report viewer, which is available in the prerequisites folder on the CD/DVD/ISO.
• You can now install service manager’s management server.
• During the install you can use machine 2 as database server.

I hope this helps you to get a quick start with SCSM…

Let’s start by looking at the alert generated by the management pack in the SCOM console:

Notice the two items marked:

• Component
• Message ID

In this example the component affected is SMS_DISTRIBUTION_MANAGER and the message ID is 2302.
Now let’s start the SCCM management console, drill down to Site Database -> System Status -> Site Status -> Your site name -> Component Status.

The right pane should now give you a list of all the SCCM components,  note the SMS_DISTRIBUTION_MANAGER and the error count:

Now right click the component with errors and select “Show Messages -> All”
A message status viewer will now popup showing some detailed information about the error:

Note that the message ID of the error reported by the management pack is listed here. This should give you some in-depth information about the error.
I hope this article helps you to trace alerts generated by SCOM down to the real SCCM errors.

1. Shut down the virtual machine in question.
2. Connect the virtual machine OS disk to another virtual machine, this can be a running virtual machine (please note that you do need to reboot this machine after you are done):- Click edit settings on the running virtual machine.- Click on “Add…” to add hardware to the machine.
   - Select “Hard disk”
   - Select “Use an existing virtual disk”
   - Browse to the virtual disk.
   - Click “Next” and “Finish”

   Your running virtual machine should now look like this:

   

   Click “OK” to apply the settings.

3. Now go to edit settings again, and change the size of the virtual disk.

   Click “OK” once again.

4. Now open the console of the running machine. And start a command prompt.
5. Type “diskpart”.Within diskpart, type “list disk” to display available disks, you should notice the disk with the free space:

   

   Now select that disk, using “select disk 2″ (2 being the disk number offcourse..)
   After that, select the appropriate partition, using “select part 1″ (1 being the partition number)
   

   Now extend the partition using the “extend” command.

   

   Hooray! :-)

6. Now shut down the virtual machine, and remove the added disk. After that you can power on the initial virtual machine.

You can download the management pack here:

• Loop through a list of Windows 2003 servers in our active directory, only Windows 2003 machines were needed. You can easily modify the search filter though.
• Set pagefile size on those servers, minimum size and maximum size set to “0″ means the pagefile settings will be set on “system managed”

So, here’s the full source of the script:

# Ask for credentials to do remote WMI.
$cred    	= Get-Credential DOMAIN\Administrator

# Filter used for active directory query. Only Windows 2003 is needed, Windows 2008 defaults to system managed pagefile size.
$strFilter 	= "(&(objectClass=computer)(operatingSystem=Windows Server 2003))"

$objDomain 	= New-Object System.DirectoryServices.DirectoryEntry
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $objDomain
$objSearcher.Filter = $strFilter
$objSearcher.SearchScope = "Subtree"

$colResults = $objSearcher.FindAll()

# Loop through list of servers.
foreach ($objResult in $colresults)
{
	$objItem = $objResult.Properties

	$name = $objItem.name[0]

	Write-Host "Setting pagefile on server: $name"

	try
	{
		$PageFile = Get-WmiObject Win32_PageFileSetting -Credential $cred -ComputerName $objItem.name
		$PageFile.InitialSize = 0
		$PageFile.MaximumSize = 0
		$PageFile.Put()
	}
	catch
	{
		Write-Host "Failed to set pagefile on: $name, no permission or server down?"
		break
	}
	finally
	{
		Write-Host "Pagefile set on: $name"
	}
}

Using default SCOM functionality, this is not possible. This is why we came up with the following idea (special thanks to my colleague Frank):

• Using two seperate subscriptions, one for “new” alerts and one for “closed” alerts.
• On the new alert subscription set a channel with a powershell script to update custom field 1 when a SMS has been sent (this subscription has the 5 minute delay)
• On the closed alert subscription set a condition to check custom field 1 to see wheter a SMS has been sent or not.

This blog post describes how this can be done within SCOM.

1. The Command Notification Channel

First we have to create a “Command Notification Channel”. Go to the “Administration” section of the SCOM management console. Click on Notifications->Channels.
Right click and select “New->Command…”.
The following wizard appears:

Give the channel a name, and click “Next >”

Enter the following settings for the channel:

Full path of the command file:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
Command line parameters:
-Command “& D:\Scripts\UpdateAlertCustomField.ps1 -alertid:”$Data/Context/DataItem/AlertId$”"
Startup folder for the command line:
D:\Scripts

Change D:\Scripts to reflect your PowerShell script location. It should now look like this:

Save the changes by clicking “Finish”

2. The used PowerShell script

To modify alert “custom field 1″, I use a small PowerShell script. The text written into the field is “Notification sent out”
The used script is displayed here, save this script as “UpdateAlertCustomField.ps1″ in the directory specified in the command notification channel above.

# Get alertid parameter
Param($alertid)
$alertid = $alertid.toString()

# Load SCOM snap-inn
add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client";
$server = "localhost"

# Connect to SCOM
new-managementGroupConnection -ConnectionString:$server;
set-location "OperationsManagerMonitoring::";

# Update alert custom field
$alert = Get-Alert -id $alertid
$alert.CustomField1 = "Notification sent out"
$alert.Update("Custom field 1 updated by UpdateAlertCustomField script")

3. A subscriber for the command

The next step is to create a subscriber which has the command notification channel created above assigned as channel.
Go to the “Administration” section of the SCOM management console. Click on Notifications->Subscribers.
Right click and click “New…”

In the “Notification Subscriber Wizard” give the new subscriber a name. In the next step of the wizard, specify your schedule as desired.
On the “Addresses” step, click “Add…” to add a new address.

In the “Subscriber Address” wizard, specify a name for the new subscriber. This can be virtually anything as no e-mails/pages/SMS messages are sent anyway.
Next, specify the “Command” channel type and select the Command channel we created earlier (Update custom field 1).

Specify your schedule as desired, click “Finish” to end the wizard. Click “Finish” again to close the “Notification Subscriber Wizard”.
You should now have a subscriber with the command channel as asigned channel.

4. The subscription for new alerts

Now that we have the command notification channel, powershell script and subscriber ready. We can create a new subscription for new alerts.
Go to the “Administration” section of the SCOM management console. Click on Notifications->Subscriptions.

In the “Notification Subscription Wizard” specify a name for the new subscription. The next wizard step is the step to define criteria for the subscription.
Specify atleast the “with specific resolution state” criteria, offcourse you can add your own other criteria here like you would normally do.

On the next wizard page (Subscribers) add the command subscriber we created in step 3, as shown below.

In the next wizard step (Channels) add the command channel we created in step 1 and specify the desired delay (5 minutes in this case). As shown below:

Click “Next”, in the summary step make sure “Enable this notification subscription” is checked and click “Finish”.
You should now have an subscription ready for new SCOM alerts.

5. Subscription for closed alerts

You can create the subscription channel like you would normally do. The only important step is to get the criteria right. We have to include custom field 1.
This is how the closed subscription criteria look:

NOTE: there is currently a bug in SCOM R2 when using custom fields in a subscription criteria!
