Recently I had a scenario where I had to rebuild the xDB Index, initially I thought it will be through Control Panel and the way we rebuild other indexes in SOLR.

But to my surprise, it wasn’t using Sitecore Control Panel or SOLR’s dashboard, it was using the Command Prompt on the server where your xConnect is hosted.

It is very simple process:

1. Go to the IndexWorker Job folder (Ex. C:\inetpub\wwwroot\{xConnect website}\App_Data\jobs\continuous\IndexWorker
2. Open command prompt in Administrator mode.
3. Go to the IndexWorker folder path:

4. Run below command as per your Sitecore version:
For Sitecore 9.x – XConnectSearchIndexer -rr
For Sitecore 10.x – Sitecore.XConnectSearchIndexer.exe -rr

Hope it helps!

Thank you.. Keep Learning.. Keep Sitecoring.. 🙂
