How to move the LiteSpeedCentral database

We are running LiteSpeed at work in order to compress our backups in SQL Server. I was tasked with moving the LiteSpeedCentral database from one SQL server to another. A simple task one might think.

By a quick search, I found a support ticket that says that you simply do a backup/restore of the database and a reconfiguration of the LiteSpeed client on each server. Simple enough, I did that.

The reconfiguration could have been easier, i.e. swap "old server" for "new server" instead of having to reconfigure everything, but sure enough, it worked.

I then got a lot of warnings on my old SQL Server telling me that some service on the LiteSpeed application server is trying to connect to the database but is failing.


I did some digging trying to find out what was causing this. The warnings came with an interval of fifteen minutes which narrowed it down to the SQL Server Agent job LiteSpeed for SQL Server Update Native Backup statistics and more specifically the query exec [LiteSpeedLocal]..[LiteSpeed_ImportNativeHistory]. When I ran this manually, it executed without errors but I still got the login failures logged on the old SQL Server.

No matter what I did to reconfigure the LiteSpeed application I could get rid of this warning. Finally I managed to find a dicussion on the Quest support forum that pointed me to the registry where I could find entries that were left pointing to the old Central Database Server. They were at HKLM/SOFTWARE/Imceda/SQLLiteSpeed/Engine/ActivityServers/[Database]/ Deleting these entries solved my issue.

So seriously Quest. Is it so hard to have a properly documented procedure for moving the database? It should be a pretty common task for customers to have to do..

Script updates of contacts in Outlook

I wanted to have all of my colleagues contact information in my iPhone so I thought of the simplest way to handle it. I quickly decided that the best way would be to simple add the appropriate domain accounts as contacts in Outlook which in a few seconds work gave me about 240 new contacts with the correct information entered as they appear in our Active Directory.

I then realised that they all had the internal speed dial phone number entered as their work number. This is a four digit number which is the same as the last four digits in the externally used number. Hence I needed a simple way to automatically add a prefix to the number for each contact, but only those that had four digits in the field since my address book is filled with external contacts as well.
After fiddling briefly with macros, csv-files and other means to get this to work, I had an epiphany and thought of PowerShell.

Three rows of PowerShell code written, tested and executed in a few minutes solved my problem

$outlook = new-object -com outlook.application
$contacts = $outlook.Session.GetDefaultFolder(10)
$contacts.Items | % { if($_.BusinessTelephoneNumber.Length -eq 4) { $_.BusinessTelephoneNumber = "123-45" + $_.BusinessTelephoneNumber; $_.save() } }


Using PowerShell to automatically update lots and lots of data will most likely be the first I think of the next time a similar task appears. This was almost ridiculously easy.

Having Visio update shape data automatically

Part of my job is to have an up to date documentation of all integrations we have. I am used to using Visio for this, and have at my previous clients kept it quite simple with manual formatting for visualizing if a message is under construction or to be deleted etc.

At this moment, I am trying out having "a lot" of documentation gathered in the Visio document. Besides having shapes for "Systems" and connections between these that each is equivalent of a "Message", I have added custom data fields on these that allow me to document metadata on each message flow. Part of the metadata I have on a message is Id, Name, Trigger, Status, Transport type and so on. Some of these fields are then used to dynamically alter the format of the connection to give a visual cue to the underlying data. If the Status is "Planned" I give the connection a green color, if the connection is marked as "Request/Response" I visualize this by having a symbol indicating so.

This all works fine and gives me one single document for the overview of the integrations. I then thought of implementing a change list so that I could follow up on revisions of the diagram. Having a normal text based change list on a separate sheet would be possible, but would incur manual work to update it and also not be mandatory (meaning that it would be forgotten and hence useless). Instead, I opted for an extra custom data field on the shapes used indicating the last time the shape was updated (data wise, not if it was moved). This is handled automatically by code that triggers when the shape data is updated.

I have one class module called "UpdateShapeTimeStamp":

Dim WithEvents appObj As Visio.Application

Private Sub appObj_CellChanged(ByVal Cell As IVCell)
    If (Cell.Shape.CellExists("Prop.Updated", 0)) Then
        Cell.Shape.CellsU("Prop.Updated").FormulaU = Chr(34) & Now() & Chr(34)
    End If
End Sub


Private Sub Class_Initialize()
    Set appObj = Application
End Sub


Private Sub Class_Terminate()
    Set appObj = Nothing
End Sub


and the Document code to enable this code:

Dim UpdateShapeTimeStampClass As UpdateShapeTimeStamp

Private Sub Document_BeforeDocumentClose(ByVal Doc As IVDocument)
    Set UpdateShapeTimeStampClass = Nothing
End Sub


Private Sub Document_DocumentOpened(ByVal Doc As IVDocument)
    Set UpdateShapeTimeStampClass = New UpdateShapeTimeStamp
End Sub


Now when changing the shape data on any shape, the event will trigger and check if the custom field "Updated" is available (meaning that it is one of my custom shapes) and if so, set it to the current datetime.

This allows me to have an automatic tracking of all changes in the diagram for each shape. Neat!

Outlook 2010 macro to copy item links to the Windows clipboard

I have used OneNote for a few years to handle all my notes regarding different projects and all information I gather during work. It works very well, and I have during this time looked at how to use Outlook in a more advanced way. Of course, I want to tie the two products together.

In the basic form, it is possible to create OneNote note taking pages from an email or appointment in OneNote. This is nice, since I can simply bring up the context menu and choose "OneNote" in order to create a place for all my notes from this specific meeting (and also write down things to bring up before the meeting occurs so that I am prepared). I have however often run into the issue that a lot of scheduled meetings will be accompanied by separate emails containing information that is relevant. In some way I'd like to group these separate items together, preferably in the OneNote page that I have created for the meeting.

I looked at how OneNote creates a page for an email, which is in the same way as for an appointment. It will bring with it a few pieces of information and also create a link back to the email item in Outlook. This link is what I am interested in.

I looked into different ways of creating it. Most promising was a utility called Linker that can copy the internal ID of an Outlook item and put it in the clipboard. The flaw was that it prefixes the ID with "outlook:". This works natively for Outlook 2003. Outlook 2007 can handle it with a registry hack. Outlook 2010 will not handle it at all.

I at least got a bit closer to a solution.

I then found out that a proper prefix in Outlook 2010 is "onenote:outlook?folder=Contacts&entryid=". I looked into how to get the ID from the Outlook item via VBA code and it proved quite easy. I then hacked together a small Macro that would grab the ID from the currently selected item, create the correct HTML link with the prefix above, and then put it in the clipboard. This did of course not work.

The clipboard is an intricate piece of Windows that can handle a lot of different data. Putting raw text into it is simple, putting an HTML link into it a bit more difficult. I turned to Google and found a support article titled "How to add HTML code to the clipboard by using Visual Basic".

This helped me create the more intricate string used to identify HTML in Windows. Using this, I had it working.

After a while I noticed that special characters (å ä ö specifically since I'm in Sweden) did not work and got encoded in a wrong way. After trying different ways of encoding the string I finally resorted to try and put the entity name ä in the string and this worked! It is HTML I'm working with after all. A quick google gave me this nice piece of code to encode special characters in a string, and now I have it all working flawlessly.

My workflow now is as follows:
An appointment is made in Outlook, by me or someone else. I rightclick this and add a OneNote page with information regarding this meeting under a tab for the specific project. Those emails that are of interest for this meeting is then linked in the OneNote page using my Macro. I simply click the email in Outlook, hit my shortcut button to copy the link, and then paste it in OneNote. I have created the macro so that the link description is fetched from the subject in the email. Perfect!

I also noticed that the macro will create links to pretty much anything in Outlook. Emails, appointments, contacts and so on. This way I can link together all items in one OneNote page so I don't have to browse or search in Outlook for whatever I need.

Here is the complete code for the macro if you are interested:

Convert C# to PowerShell code

Yesterday I saw a link on our company's intranet linking to a colleague's blog. It proved to be a very nice read. Among the .Net Reflector addins available on CodePlex, there's one for PowerShell allowing you to convert C# code to PowerShell. That will come in handy a lot of times since I definately write C# code faster than PowerShell code. Thanks for that tip!
The only downside is that Reflector for the last year requires a license fee and I have since switched over to ILSpy. With this and the other plugins available, it's either time to switch over to Reflector again, or rewrite some of the plugins to work with ILSpy.

Dangers when upgrading the Codeplex SFTP adapter

I encountered some dangers that one can run into when upgrading the BizTalk SFTP adapter that can be found on Codeplex.

On one installation where the adapter is used did the issue of the adapter stop working frequently arise. When the issue was fixed in a subsequent version of the adapter, it was upgraded, but the problem remained.

When I looked at the server, I noticed that the adapter never had got upgraded, even though they very well installed the new version. I then replicated what I believe to be the steps taken during the upgrade in order to fully understand what had happened.

I learned that when upgrading version 1.3.3 to 1.4.0, it is necessary to completely uninstall the previous version before installing the new. This was never done during the upgrade process. The old version remained installed and the setup program for the new version reported back that the installation was successful. The BizTalk administrator never noticed the dual entries in the Add/Remove programs window nor the old timestamps in the adapter installation folder (which was how I noticed it from the beginning).



Uninstalling the two adapter entries in the control panel and then reinstalling the new version solved the issue as can be seen in the installation directory.


I then also noticed that when properly upgrading the adapter, receive locations bound to the SFTP adapter will not start unless you for each and every one open the adapter properties windows and save it. This is due to a difference in the properties that will make the bindings fail otherwise, rendering the port to shut down.

BizTalk 2010 and Dynamics AX 4.0

We just did a quick check for a client investigating the possibility to upgrade their BizTalk 2006 platform to the latest (2010) version. The main issue was whether the vast amount of integrations to their Ax 4.0 system would still work.

Some of the integrations are made using the Ax AIF adapter in BizTalk and while their is a lot of information on the web that doesn't say that BizTalk 2010 can work with the Ax 4.0 adapter, there is not a single document that explicitly says that the two are incompatible even though you more or less can assume so based on the information available. Mainly because BizTalk 2010 requires Windows Server 2008 and the adapter is not supported on this platform. The adapter is not supported on 64-bit systems at all and I doubt there is many admins looking at installing a fresh new integration platform today and not putting it on a 64-bit Windows.

We checked with Microsoft just to be sure and received the answer that BizTalk 2010 and Ax 4.0 cannot be integrated using the adapter. Not even Ax 2009 is fully supported by BizTalk 2010 as of today which is an interesting fact. Instead are we investigating the amount of work needed to change the adapter based flows to MSMQ integrations instead. The upgrade of the integration platform is more important than to keep an outdated adapter working..

BizTalk 2010 certification

I've been waiting for a new exam for BizTalk to appear since the "current" one has been for 2006r2 for quite a while. Today I took a new look and found that Exam 70-595: Developing Business Process and Integration Solutions by Using Microsoft BizTalk Server 2010 is available. The old exams for 2006 and 2006r2 are set for retirement this summer.

Time to update the skills that I rarely (or never) use such as EDI and RFID and then it's off to take the test.

Recycle IIS application pools using PowerShell

I have been working on a collection of deployment scripts for BizTalk solutions using PowerShell. One functionality is installation of services hosted in the IIS. After installation, the application pool need a restart in order to properly pick up the new/updated services.

At first, I just recycled all available application pools by the following command line

& $env:windir\system32\inetsrv\appcmd list apppools /xml | & $env:windir\system32\inetsrv\appcmd recycle apppools /in

First we list all available application pools and then we pipe this list as input into the recycle command.

While nice, it is unnecessary to recycle those application pools that are unaffected by our installation.

The main finesse in my scripts are that they are picking up all information on what to do from a configuration file. This XML file includes among other things the application pool for each service to install in IIS. Based on this I updated my recycle command to recycle each and every application pool that were specified in the configuration file. In order to not restart an application pool more than once, I pipe the foreach with sort-object and get-unique.

# List to hold the apppools
$appPools = New-Object System.Collections.ArrayList

# Loop through the objects in the xml file
# and extract the apppool name and add to the list
ForEach($wcfSetup in $xmlFile.DeployConfiguration.WcfSetups.WcfSetup)
{
    [void]$appPools.Add($wcfSetup.ApplicationPool.Trim())
}

# Recycle each unique apppool in the list
foreach($appPool in $appPools | sort-object | get-unique)
{
    & $env:windir\system32\inetsrv\appcmd recycle apppool /apppool.name:"$appPool"
}

Creating a multidimensional strongly typed array in Powershell

When getting stuck for a short while trying to figure out how to create a strongly typed multidimensional array in Powershell I tried to find an example on the net just to find that there simply just is no example of it to be found. Maybe it's too easy? The Technet page on the New-Object cmdlet gave me what I needed.

The way I later on created my two dimensional array was like this:

$d = New-Object 'Object[,]' 10, 20
This is however created as an Object array while I needed int. I changed the code to this:

$d = New-Object 'Int32[,]' 10, 20
Then I thought that it should be possible to streamline it a bit so I got this:

$d = Int32[,] 10, 20
Simple enough. When I see it, I wonder why I couldn't figure it out quicker.
