Microsoft SQL Server 2012 Service Pack 1 Summary

By:   |   Comments (1)   |   Related: > Install and Uninstall


This tip aims to provide a description of Service Pack 1 for SQL Server 2012, including a description of the contents, the changes it makes to the SQL Server product family, identified bugs (and hotfixes to correct them), a description of the installation process and links for the download and further information.



SP1 for 2012 is 'notorious' in that after SP1 is installed on certain server configurations, the SQL Server Installer process starts repeatedly and CPU usage will ramp up. Event numbers 1001 and 1004 (source: MsiInstaller) will appear in the Windows Application Log. The installation of SQL Server may be unusable after this occurs. This problem has been acknowledged by Microsoft in KB2793634 (see bottom for link) and can be temporarily worked around by pausing the NGEN service in the services.msc panel in Windows. A hotfix is available from Microsoft, although if you have installed any other hotfixes or Cumulative Update (CU) 1 since the installation of SQL Server 2012 RTM, you may wish to upgrade to CU2 instead rather than rollback individual hotfixes.

Issues Fixed

SQL Server Service Pack 1 (SP1) is the first Service Pack released for the SQL Server 2012 product. It fixes 90 bugs identified in the RTM version of the product, from performance issues to software glitches. A complete list can be found below and is also available from Microsoft in the link supplied under 'More Information':

Service Pack 1 was released on 11/09/2012 in twelve languages. Download files are available in both .iso (DVD-image) format, .box format and .exe format in both the slipstream edition (complete 2012 installation with SP1 included) and SP1 standalone version. SP1 is available for all versions and editions of SQL Server 2012, and also for partial elements such as the client and manageability tools (SSMS, etc.) as package KB2674319 available in the link at the end of this tip, although if you have the database engine installed, the full SP1 product should be installed. It is available in both 32-bit and 64-bit editions. It is also available for the SQL Server 2012 Feature Pack only, and the installation of SP1 should be completed on an individual basis from the SQL Server 2012 SP1 Feature Pack download, link also below.


As previously stated, depending on your configuration (Microsoft unfortunately is not forthcoming about the exact details), you may wish to install KB2793634 to fix the installer issue. However there are certain other issues which are detailed in the Release Notes (linked below) of which you should be aware before installing SP1:

1) Reinstallation of SQL Server Failover Cluster - This will fail if reinstalling on a node in a failover cluster if using the same IP address. The reason for this is that the Resource Group is not fully deleted on uninstallation, so on reinstallation an error is generated. Workaround: Uninstall the Resource Group, or use a different instance name.

2) PowerPoint Configuration Tool doesn't recreate the PowerPivot Gallery - this issue affects administrators of PowerPivot and occurs because the default behavior is to create a new 'Team Site'. To fix this issue, install a new application, 'PowerPivot Gallery', from the Site Contents page and ensure the PowerPivot Feature Integration for Site Collections feature is active.

3) PowerPivot for Excel 2013 must be installed from Excel, not from SQL Server 2012. In addition, the versions of PowerPivot for Office 2010 as supplied with SQL Server 2008 R2 and 2012 are not compatible with Excel 2013. Workaround - install the COM add-in in Excel. For full instructions, see the Release Notes, item 2.2.

4) SharePoint Server 2013 must be installed prior to SQL Server Reporting Services 2012. This is because installing in the reverse order means misconfiguration of the SharePoint farm. According to the Microsoft article 'Business Intelligence Features and SharePoint 2013 (SQL Server 2012) linked to at the end of this tip. In essence the steps are as follows:

  • Install SharePoint Server 2013
  • Enable Excel Services
  • Install SQL Server Analysis Services (SSAS) in SharePoint mode
  • Grant administrator permissions on SSAS to the SharePoint farm and services accounts
  • Configure Excel Services to use the SSAS services
  • Install Reporting Services (SSRS) in SharePoint mode
  • Install the Reporting Services add-in for SharePoint products
  • Configure SSRS, the SharePoint service and at least one SSRS service application

5) PowerView in SharePoint 2013 requires an SSAS .dll file (Microsoft.AnalysisServices.SPClient.dll). Workaround: Install spPowerPivot.msi on the SharePoint server, available as part of the SQL Server 2012 SP1 Feature Pack (linked below).

6) PowerView sheets in a PowerPivot workbook are deleted after a data refresh. Workaround: Create a new PowerPivot workbook that defines the data model only. Keep Excel and other PowerView sheets separate so the data refresh affects only the data model sheet.

7) Data Quality Services (DQS) is mistakenly available in editions other than Enterprise, BI and Developer Editions of SQL Server. After SP1 installation, DQS will no longer be made available in other editions.

8) SSMS - SQL Server Management Studio 2012 full edition has been mistakenly made available in the Express Edition instead of SSMS 2012 Express Edition. This is corrected in SP1.

9) Change Data Capture (CDC) components for Oracle must be upgraded manually to SP1. These can be obtained from the SQL Server 2012 SP1 Feature Pack download page (linked below).

10) Updates to the SQL Server Data-Tier Application Framework (DACFx). In the interests of brevity these changes have not been included here, but can be found in the SQL Server 2012 SP1 Release Notes, item 7.0.


Simply download and run the correct version (32-bit, 64-bit, or appropriate slipstream edition) from the download page linked below. Then step through the dialog screens to confirm installation and begin the installation process. On a 32-core server with Windows Server 2008 R2, this process took approximately 45 minutes, but your mileage may vary.
