Sitecore 10.2 Headless SXA is looking for "master" db on CD server

Hi Folks,

Sometimes you are trying to troubleshoot one thing and end up solving another :), How many of you have ended up same? 

Well, I was actually troubleshooting the high CPU and no. of requests on CD was trying to find some error patterns from Sitecore logs for one of the issues we were facing, there was one specific error which we kept observing was below

Exception

and if you drill further down into it, Sitecore was looking for master DB on CD servers, which is not possible, so definitely, this is bug

I previously faced the same error but for other assembly and to troubleshoot and resolving that the approaches were different but for both meaning of the error is same, for 10.3 where i got the error is drafted here Error in Sitecore 10.3 XM with CDs - Could not find configuration node: database/database[@id='master']


Troubleshooting

It was clear that because some the code which is in "VersionInitializer" class of "SItecore.XA.Foundation.Upgrade.dll" is referring to "master" database on a CD server.

So, I just tried dissembling the DLL to understand what's going on and you can see below

It is clearly seen that code is referring to wrong DB instead of the context DB, it is "master" DB and that is the reason of the error

Solution

Further troubleshooting and research suggested that this can be safely ignored, and this comes only when the instance is starting, but just to keep our logs clean we just commented out below lines from "\App_Config\Modules\SXA\Foundation\Sitecore.XA.Foundation.Upgrade.config" of CD instance


and that is the suggested approach from Sitecore.

Why SitecoreAI - Getting into the shoes of the customer how to select right CMS

Hi Team, Lately, I have been talking to lot of our customers / potential customers and having pre-sales demos where one question always comes is "Why Sitecore" ?  Now this question can be for any product which is out for sell. And as a technician I always get into product technical features, but at the same time as a pre-sales guy, it also makes me think, surely all competitive products have same features, so definitely answer to this is not in the technicalities.  If you step back and think, we are also a customer in our daily life and buy lot of things, what is that process we go through? When we buy, how can your customer decide if this is a right fit for you or not, why we select A over B? Is it price? is it service? Is it a brand? Is it about features? Is it about brand loyalty?  When it is a technical product, I am sure it cannot start with the technicalities of the product or selecting product itself, 100% not, I feel decision is always business strategy first and ...

Zero to Hero - A real life RCA of exact issue in Sitecore Managed Cloud environment

Hello All, The purpose of today's post is to share a real life burning and escalated scenario which was new to me and how did I approach it and how big the escalations were and what was the outcome Sitecore's goodwill was at stack not because Sitecore is not capable of handling it but just because our environment was Sitecore Managed Cloud, and any issue that comes if its infra, back end code, front end code will be first pointed as Sitecore issue and that is where our consultancy and experience will play a role to prove that it is not Sitecore issue.  Issue we faced Out of the blue our site started giving "504 Gateway Time-out", and it was reported that almost everyone is getting this error, but when we used to browse the site, everything looked good and never 504. 504 Gateway Time-out error tells that, That the request went to Content Delivery servers of Sitecore from gateway, but gateway did not get response in time from those CDs and hence it gave time out error. ...
