The AcquireConnection method call to the connection manager failed with error code 0xC0202009

I had one of those annoying problems with executing a SSIS package that took up most of the morning today (and a couple of hours yesterday) where you get an error which many people have had, but none of their solutions work. I guess it is such a generic error code it can relate to many different issues hence dozens of different (wrong) suggestions. What confused matters was that although it completed successfully in SSDT, it failed when being validated on our newly created SSISDB Catalog. I didn't know whether it was a problem with the package and/or its parameters or the SSISDB Catalog installation or Environment.

If you haven't set up an Integration Services Catalog (a new feature of SQL 2012) yet I definitely think it is worth looking at. I found an excellent guide here that takes you through it all.

In our case we had two connection managers, the source was a table in a SQL Server 2012 database and the destination a table in an Access 2010 database. The server with the Integration Services Catalog (SSISDB) was on a 64 bit SQL 2012 cluster so the first thing I had to do was install the Access 2010 64 bit drivers on each node. This was painless and didn't require a boot or anything.

I then deployed the SSIS solution to the server, configured the packages parameters and the SSISDB's Environment variables but kept getting an error similar to this, when I ran the Validate command.

I ensured that the domain account that SQL Server (and the Agent) had permissions to the share that the Access database was on. I tried it with and without using the SSISDB Environment variables. In the end it turned out to be something I had come across before: running a SSIS package developed on a 32 bit OS (the developers workstation) on a 64 bit server. To resolve this I made some changes to the package in SSDT, I changed the ForcedExecutionValueType property to Int64 and changed the DelayValidation property from False to True.

I did this on my workstation, redeployed the solution to the server and ran the Validate command which succeeded.

I then created a SQL Agent job to execute the package on a schedule which also succeeded.

Hope this helps someone.

How to move the Microsoft Assessment and Planning Toolkit (MAP) database to a different drive

The Microsoft Assessment and Planning Toolkit (MAP) is a very useful tool for scanning your network to find instances of SQL Server plus all manner of detailed information about the installed product, OS and hardware it sits on.


<Click image to enbiggen>
There is an issue with it the database it uses to store the data it collects, however. Assuming you don't have an instance called MAPS on your server, the product will install using LocalDB (a cut down version of SQL Server Express) and puts the databases on your C: drive. If you then scan a large network you could easily expand the database to 10GB which may cause issues on a server when that drive is often one of the smallest. However, there is a simple solution: connect to LocalDB using Management Studio, detach the databases, move to a different drive, set permissions on the new location if required and reattach the database. How do you connect to LocalDB? Here you go:

Connect to (localdb)\MAPTOOLKIT

SAN performance testing using SQLIO

Introduction
This document describes how to use Microsoft’s SQLIO to test disk/SAN performance. It is biased towards SQL Server – which uses primarily 64KB and 8KB data pages so I am running the tests using those cluster sizes, however, other sizes can be specified.  Download SQLIO from https://www.microsoft.com/en-gb/download/details.aspx?id=20163 SQLIO is a command line tool with no GUI so you need to open a command prompt at C:\Program Files (x86)\SQLIO after you have installed it. Configuration First of all edit param.txt so that you create the test file we will be using. The file needs to be bigger than the combined RAID and on-board disk caches. In this case we are using a 50GB file.
The “2” refers to the number of threads to use when testing, you don’t need to change this now. The “0x0” value indicates that all CPUs should be used, which you probably don’t want to change either, “#” is a comment. The only part you may want to change is 51200 (50GB) and the drive letter. After …

How to configure the SSAS service to use a Domain Account

NB Updating SPNs in AD is not for the faint hearted plus I got inconsistent results from different servers. Do so at your own risk! If you need the SSAS account on a SQL Server to use a domain account rather than the local “virtual” account “NT Service\MSSQLServerOLAPService”. You may think you just give the account login permissions to the server, perhaps give it sysadmin SQL permissions too. However, if you try and connect to SSAS remotely you may get this error:

Authentication failed. (Microsoft.AnalysisService.AdomdClient) The target principal name is incorrect (Microsoft.AnalysisService.AdomdClient)

From Microsoft: “A Service Principle Name (SPN) uniquely identifies a service instance in an Active Directory domain when Kerberos is used to mutually authenticate client and service identities. An SPN is associated with the logon account under which the service instance runs. For client applications connecting to Analysis Services via Kerberos authentication, the Analysis Services clien…
