XDB Disabled - Still getting tracking error in the logs

Question

I have xdb disabled:

xdb.Enabled = false xdb.Tracking.Enabled = false

Im still getting xdb related errors in the logs. Should this all be disabled (Sitecore 9.3):

Answer 1

I had the same problem with both xdb and xdb tracking disabled and it appears to be a sitecore 9.3 bug, so i got this workaround from sitecore support:

As a workaround please try to disable in the \App_Config\Sitecore\Marketing.Tracking\Sitecore.Analytics.Tracking.config file:

<events>
<event name="sessionEnd:batch:starting">
<handler type="Sitecore.Analytics.Events.BatchEventHandler, Sitecore.Analytics" method="OnBatchStarting" />
</event>
<event name="sessionEnd:batch:ended">
<handler type="Sitecore.Analytics.Events.BatchEventHandler, Sitecore.Analytics" method="OnBatchEnded" />
