Error in Sitecore 10.3 XM with CDs - Could not find configuration node: database/database[@id='master']

Hi Team,

Recently we came across two distinct scenarios with same error message. 

1) We started getting below error when we try to hit our layout service API endpoint.


If we hit end point of CM, it was working fine and when we try to hit end point of CD it was giving this error, It was clear there is something in backend expecting master DB instead of WEB DB

In first scenario my colleague Jatin also got same issue while setting up docker instance for 10.3, and my friend Akshay Barve and I had the same observation.

2) Second scenario I was having the same exception, It was another project on 10.3 XM with CD, It was one of the migration project so we were migrating from 10.2 to 10.3, Older site was not giving any error but new site the moment we hit, it was giving same exception in the log

Issue in second scenario was in site grouping there was only site and both CM and CD URLs were given in host name and had WEB db as database, so basically there was no preview site, but both of the URLs were trying to show data from a WEB db, but issue was same because it had WEB DB and some configuration was still trying to find master DB either from DLL or from Config.

So different scenarios but same behavior and pointed to a same problem.

To troubleshoot second scenario where after upgrading it started giving error, we tried following. 

1) We checked our code and tried to find if any code is using master db configuration 

2) We also tried to check if any existing new 10.3 DLLs are having any master db reference

3) We checked in whole app_config folder and tried to search <databaseName>master</databaseName> configuration

and that is where Jatin pointed the same issue we faced and changing this file in order to give CD specific role to make it work

Same patch configuration worked for all of the two scenarios. See below in green,  

Solution

We created a patch file with below configuration, it is clearly seen that without this patch file CD will was looking for <databaseName>master</databaseName> instead of a WEB DB.

<?xml version="1.0"?>

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:set="http://www.sitecore.net/xmlconfig/set/">

  <sitecore role:require="ContentDelivery">

    <layoutService>

      <configurations>

        <config name="sxa-jss">

          <requestContext type="Sitecore.LayoutService.Configuration.DefaultRequestContext, Sitecore.LayoutService">

            <databaseName>web</databaseName>

          </requestContext>

        </config>

      </configurations>

    </layoutService>

  </sitecore>

</configuration>

Everything worked fine after this patch.

PS: This behavior is registered as a bug by Sitecore support with 578367 reference number, and they acknowledged this behavior.

High CPU to completely normal CPU - SXA issue, SXA pages not loading in mobile device

  Hi Team, Today i am going to share one of the nightmarish issue with you all, We are having Sitecore 9.1.1 hosted in azure PaaS environment Our site was working just fine and no noise, but we have been working on a feature release where 7-8 months of development needed to be released to production, Big GO LIVE event right?  Also to make the development smoother we also introduced BLUE/GREEN deployment slots in the same release, so we can easily SWAP slots and go live Everything went well, we went live, we even did load and performance testing on our staging and pre-prod and we were confident enough of results Very next day we started getting "SITE DOWN" alerts, and also product owners and clients mentioned that site is very slow for them in US time and in our morning when we were accessing it, it was working lighting fast so we were clue less at start, but we started digging  1) First thing caught our eyes were HIGH CPU spikes, in US time, also without any traffic CPU u...

Set up leprechaun code generation with Sitecore XM Cloud Starterkit

Hi Sitecorians, It has been amazing learning year so far and with the change in technology and shift of the focus on frontend frameworks and composable products, it has been market demand to keep learning and exploring new things. Reasons behind this blog Today's topic is something that was in my draft from April-May, and I always thought that there is already a good documentation out there for  Leprechaun  and a blog post is not needed, Until I realized that there was so many of us facing same kind of issues and same kind of problems and spending same amount of time, That is where I thought, if I could write something which can reduce that repetitive troubleshooting time, That would really help the community. 1)  In a project environment, if we get into some configuration issues, we resolve them, we make sure we are not blocked and continue, but if you think same issue, same step and same scenario will come to other people, so if we can draft it online, it will help othe...
