Sitecore Commerce 9 Update 2 and Step-by-step Install Guide on your machine

This one is a summary of my own experience for Sitecore Experience Commerce 9 Update 2 (aka Sitecore XC 9.0.2) installation on my machine. I’ve had much experience in Sitecore XC9 installation and Sitecore XC9 Update 1 installation so I decided to go only with:

I do hope that this blog post is helpful for your own journey as well.

Setup Prerequisites

Step-by-step guide

  1. install the ones below if not yet 😀
  2. rebuild the Link databases for the master and core databases if not yet:
    • on the Sitecore Launchpad, click Control Panel, and in the Database section, click Rebuild Link Databases
    •  select the master and core databases and then click Rebuild
    • sc9com_1
  3. rebuild the search indexes if not yet:
    • on the Sitecore Launchpad, click Control Panel, and in the Indexing section, click Indexing manager
    •  in the Indexing Manager dialog box, click Select all, and then click Rebuild
    • sxc902_7
  4. DO NOT stop the xConnect site sc9com.xconnect.local
    • from the installation guide with love (Page 9)
    • sxc902_6
  5. create a new folder E:\sc9_com_install
  6. create a certificate for the Sitecore Commerce Engine Connect to authenticate with the Sitecore XC Engine:
    • launch PowerShell as an administrator
    • create the certificate by running the following cmdlet:
      • New-SelfSignedCertificate -certstorelocation cert:\localmachine\my -dnsname “storefront.local”
    • export the certificate to a file by running the following cmdlet:
      • Export-Certificate -Cert cert:\localMachine\my\<Thumbprint-of-cert> -FilePath E:\sc9_com_install\storefront.local.cer
    • sc9com_3
  7. download MSBuild Microsoft Visual Studio Web targets (available from Nuget) then extract the Web targets package, copy the \tools\VSToolsPath\Web\Microsoft.Web.XmlTransform.dll file into E:\sc9_com_install
  8. download Sitecore Experience Accelerator 1.7.1 (Note: must log into before downloading) and put it into E:\sc9_com_install
  9. download Sitecore Powershell Extensions 4.7.2 then put it into E:\sc9_com_install
  10. download and unzip Packages for On Premises 2018.07-2.2.126 (Note: must log into before downloading) then put it into E:\sc9_com_install
  11. unzip E:\sc9_com_install\ and then rename E:\sc9_com_install\SIF.Sitecore.Commerce.1.2.14 to E:\sc9_com_install\SIF for a better practice
  12. unzip the E:\sc9_com_install\
  13. unzip the E:\sc9_com_install\ file then copy the E:\sc9_com_install\Sitecore.Commerce.Engine.SDK.2.2.72\Sitecore.Commerce.Engine.DB.dacpac file into E:\sc9_com_install
    • Note: you will see the following error message if you copy / paste the one of XC 9 Update 1
    • sxc902_5
    • ERROR Message=SQL.InsertEntity.Fail: Id=’Entity-PolicySet-ControllerMethodRolesPolicySet’|Environment=’GlobalEnvironment’|Message=’Procedure or function sp_CommerceEntitiesInsert has too many arguments specified.

  14. unzip E:\sc9_com_install\
    • open E:\sc9_com_install\Sitecore.Commerce.Engine.2.2.126\wwwroot\bootstrap\Global.json
    • replace the Database‘s value to “SitecoreCommerce9_Global” at line 109 (the default value SitecoreCommerce_Global is NOT correct)
    • ensure the Server‘s value is “.” at line 113 (it’s empty by default)
    • sxc902_4.png
    • zip the folder E:\sc9_com_install\Sitecore.Commerce.Engine.2.2.126 as E:\sc9_com_install\Sitecore.Commerce.Engine.2.2.126\ file then overwrite E:\sc9_com_install\ with it
  15. download sc9_com_install.ps1 and put it into E:\sc9_com_install\SIF then open it to correct 09 parameters below:
    1. $SitePrefix
    2. $ScInstallDirectory
    3. $SiteHostHeaderName
    4. $SqlServer
    5. $SqlDbPrefix
    6. $CommerceEngineCertificatePath
    7. $SolrUrl
    8. $SolrRoot
    9. $SolrService
  16. (optional): you can specify any local account (note: it will be created automatically if non-existent) to be set up for the various application pools that are created as part of the deployment at line 76-77 of sc9_com_install.ps1
    • sxc902_1
  17. (optional): if you play with SQL Server 2017, you will have to download DeployCommerceDatabase.psm1 then overwrite E:\sc9_com_install\SIF\Modules\DeployCommerceDatabase\DeployCommerceDatabase.psm1
  18. (optional): if you have multiple instances of SQL Server on your machine, you will have to:
    • unzip E:\sc9_com_install\
    • open E:\sc9_com_install\Sitecore.Commerce.Engine.2.2.126\wwwroot\bootstrap\Global.json
    • replace the Server’s value to your SQL Server instance at line 113 (Note: double-backslash escape if any)
    • sxc902_3.png
    • open E:\sc9_com_install\Sitecore.Commerce.Engine.2.2.126\wwwroot\data\Environments\PlugIn.Habitat.CommerceAuthoring-1.0.0.json then replace the Server‘s value to your SQL Server instance at line 130 (Note: double-backslash escape if any)
    • open E:\sc9_com_install\Sitecore.Commerce.Engine.2.2.126\wwwroot\data\Environments\PlugIn.AdventureWorks.CommerceAuthoring-1.0.0.json then replace the Server‘s value to your SQL Server instance at line 130 (Note: double-backslash escape if any)
    • zip the folder E:\sc9_com_install\Sitecore.Commerce.Engine.2.2.126 as E:\sc9_com_install\Sitecore.Commerce.Engine.2.2.126\ file then overwrite E:\sc9_com_install\ with it
  19. (optional): you may get timeout exceptions (some tasks’ execution timeout is only 12 minutes by default and the remote query timeout of SQL Server is only 10 minutes by default) so I suggest:
    • download SitecoreUtilityTasks.psm1 then overwrite E:\sc9_com_install\SIF\Modules\SitecoreUtilityTasks\SitecoreUtilityTasks.psm1 in order to increase the execution timeout
    • download PerformanceTweak.config then put it into  \sc9com.local\App_Config\Environment in order to turn all Sitecore jobs off and disable xDB for a better installation (you know, it’s a super long operation :D)
    • configure the remote query timeout option of SQL Server:
      1. using SQL Server Management Studio
      2. in Object Explorer, right-click a server and select Properties
      3. under Remote server connections, in the Remote query timeout box, type or select a value from 0 through 2,147,483,647 to set the maximum number seconds for SQL Server to wait before timing out
    • consider to put $global:ProgressPreference = ‘silentlyContinue’ into the sc9_com_install.ps1 in order to speed up the operation
  20. launch PowerShell as an administrator
    • sc9com_6
    • hopefully there is nothing can stop the installation process now
    • sxc902_10.png
  21. open a browser then navigate to storefront.local/, you would see the default page of Sitecore webiste. That’s because we don’t use the default host name so we need to correct it inside Sitecore
    • log into sc9com.local/sitecore/
    • access /sitecore/content/Sitecore/Storefront/Settings/Site Grouping/Storefront
    • update Host Name to storefront.local and then publish it
    • sc9com_8.png
    • refresh storefront.local/, you would see something like this
    • sxc902_8.png
    • I’m sure that you want to make it more fancy so access /sitecore/content/Sitecore/Storefront/Presentation/Page Designs
    • update Theme to Storefont Branded and then publish it
    • sc9com_14
    • refresh storefront.local/, you would see something like this
    • sxc902_9.png
  22. DO NOT forget to perform Post-Installation Steps

The recommendations

  • we can remove the tasks completed from E:\sc9_com_install\SIF\Configuration\Commerce\Master_SingleServer.json and re-do Step 20 if there is something wrong (especially for Note: some known issues below) so that we are able to save a lot of time 😀
  • if there is something wrong during installation process, we always have a chance to correct it via json files (note: need to do IIS reset after updating):
    1. C:\inetpub\wwwroot\SitecoreIdentityServer\wwwroot\appsettings.json
    2. C:\inetpub\wwwroot\CommerceShops_Sc9\wwwroot\bootstrap\Global.json
    3. C:\inetpub\wwwroot\CommerceOps_Sc9\wwwroot\bootstrap\Global.json
    4. C:\inetpub\wwwroot\CommerceMinions_Sc9\wwwroot\bootstrap\Global.json
    5. C:\inetpub\wwwroot\CommerceAuthoring_Sc9\wwwroot\bootstrap\Global.json
    6. C:\inetpub\wwwroot\CommerceShops_Sc9\wwwroot\data\Environments\Plugin.SQL.PolicySet-1.0.0.json
    7. C:\inetpub\wwwroot\CommerceShops_Sc9\wwwroot\data\Environments\PlugIn.Habitat.CommerceAuthoring-1.0.0.json
    8. C:\inetpub\wwwroot\CommerceShops_Sc9\wwwroot\data\Environments\PlugIn.AdventureWorks.CommerceAuthoring-1.0.0.json

How to uninstall it?

  • download sc9_com_uninstall.ps1 and put it into E:\sc9_com_install then open it to correct 07 parameters below:
    1. $EngineSuffix
    2. $Prefix
    3. $SolrService
    4. $PathToSolr
    5. $SqlServer
    6. $SqlAccount
    7. $SqlPassword
  • launch PowerShell as an administrator
    • sc9com_15.png
  • hopefully, it runs well and cleans everything up

Note: some known issues

  1. The service cannot accept control messages at this time
    • sc9com_16.png
    • access IIS, start sc9com.local site and sc9com.local application pool manually (note: you may need to do it several times) if they’re in STOP status, somehow IIS cannot restart those ones after stopping them
  2. The wait operation timed out: [SqlException (0x80131904): Connection Timeout Expired. The timeout period elapsed during the post-login phase. The connection could have timed out while waiting for server to complete the login process and
    respond; Or it could have timed out while attempting to create multiple active connections.

    • sc9com_17.png
    • open E:\sc9_com_install\SIF\Configuration\Commerce\Master_SingleServer.json to remove the tasks completed
    • for instance, I would remove all the completed tasks before InstallSXAFrameworkModule then re-do Step 20 again
    • sc9com_18.png
  3. Request timed out:  Exception Details: System.Web.HttpException: Request timed out.
    • sc9com_19.png
    • my suggestions:
      1. open E:\sc9_com_install\SIF\Configuration\Commerce\Master_SingleServer.json to remove the tasks completed
        • for instance, I would remove all the completed tasks before PublishExtensions then re-do Step 20 again
      2. consider to perform Step 19 as well if solution #1 does not work as expected then re-do Step 20 again
  4. Something went wrong restarting SQL server again: Cannot validate argument on parameter ‘InputObject’. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.
    • sc9com_22
    • somehow SQL Server window service cannot restart after stopping, ensure SQL Server window service is running
  5. Install-SitecoreConfiguration : Cannot find path ‘C:\inetpub\wwwroot\CommerceOps_Sc9\wwwroot\config.json’ because it does not exist.
    • sc9com_50
    • in Step 15, ensure to create correctly (especially directory structure)
  6. Get Token From Sitecore.IdentityServer: HTTP Error 503. The service is unavailable
    • sc9com30.jpg
    • my suggestions:
      1. ensure to install .Net Core stuffs
      2. correct connection string in “C:\inetpub\wwwroot\SitecoreIdentityServer\wwwroot\appsettings.json” and then do IIS reset
      3. correct the application pool of SitecoreIdentityServer site in IIS
  7. Ensure/Sync default content paths for environment AdventureWorksAuthoring failed
    • sxc902_2
    • ensure to perform Step 14 and Step 18 correctly
  8. ERROR Exception when executing agent aggregation/pathAnalyzerHistoryAgent
    Exception: Sitecore.XConnect.XdbCollectionUnavailableException
    Message: The HTTP response was not successful: Forbidden
    Source: Sitecore.Xdb.Common.Web

    • have a look at
    • ensure to remove all non-self-signed certificates out of Trusted Root Certification Authorities certificate store (you can move them to Intermediate Certification Authorities certificate store)
      • Note: should use this Windows Powershell command Get-Childitem cert:\LocalMachine\root -Recurse | Where-Object {$_.Issuer -ne $_.Subject} to find them out

Happy Sitecore Installation!

  1. New update is so weird, I had bunch of issues and errors during the installation and now I have error on logs which says sitecore_sxa_master core for solr is missing.


    1. By default, you cannot install multiple Sitecore Commerce instances on a same machine so I highly recommend to have a look at

      As I know so far, it’s a known issue of SXA 1.7.1 (both “sitecore_sxa_master_index” and “sitecore_sxa_web_index” are NOT created automatically via the installation process). You should create them manually.

      Don’t forget to reconfigure SXA indexing in case you want to use the new ones rather than the default ones
