2. Create a new core.properties file under /var/cb/data/solr/cbevents/reader/ 

   • touch core.properties

3. Set following parameters: by editing the file 

   • #Written by <Author> 
     #<Current Date> 
     name=reader 
     configSet=cbevents_v2

4. Save the file.
5. Change ownership of the file to cb:cb 

   • chown cb:cb  core.properties

6. Change permissions of the file to -rw-r--r--

• chmod 644 core.properties
