Display Anonymous Contacts in Sitecore Experience Profile

After installation of Sitecore 9 update 2, I observed that Experience profile does not show anonymous contact on experience profile but it exists in xConnect Database.

To show to anonymous contact in experience profile we need to enable anonymous contact and perform the below steps:

Step 1: Go to the xConnect root path “ C:\xconnect root path\App_data\jobs\continuous\IndexWorker\App_data\Config\Sitecore\SearchIndexer”, open “sc.Xdb.Collection.IndexerSettings.xml” file and IndexAnonymousContactData to true as below:

 <IndexerSettings>
    <Type>Sitecore.Xdb.Collection.Indexing.IndexerSettings, Sitecore.Xdb.Collection</Type>
    <LifeTime>Singleton</LifeTime>
    <Options>
       <SplitRecordsThreshold>25000</SplitRecordsThreshold>
       <IndexPIISensitiveData>false</IndexPIISensitiveData>
       <IndexAnonymousContactData>true</IndexAnonymousContactData>
    </Options>
 </IndexerSettings>

Step 2: Add the IIS app pool user to the “Performance Monitor Users” group. Run Command prompt as administrator and execute below command:
CMD> net localgroup “Performance Monitor Users” local /add
CMD> net localgroup “Performance Monitor Users” xConnect /add

It will resolve “Access to the registry key ‘Global’ is denied” error which you can find in

the log file. To confirm that the user added or not go to the performance monitor user

window and confirm as below:

Step 3: In the final step Rebuild the xDB index in Solr. Go to the server where the xConnect Search Indexer is running and open command line.Navigate to the folder that contains the service – for example: C:\inetpub\wwwroot\<xConnect Collection Search service root>\App_Data\jobs\continuous\IndexWorker.Run “XConnectSearchIndexer -rr” (alternatively XConnectSearchIndexer -requestrebuild).

     The command registers a small document in the live core signaling that the rebuild should be started. The xConnect Search Indexer will notice the document and start the rebuild process.For more detail about Rebuild the xDB index in Solr, refer:

Step 4: Run experience profile and get your anonymous contact as below:

Happy Sitecoreing 😊
