In case of an extended data center failure, the secondary data center can be promoted to primary.

You need to edit the file in the Workspace ONE Access appliances in the secondary data center to configure the appliances for read-write mode.

Make these changes in each Workspace ONE Access appliance in the secondary data center.


  1. Using an SSH client, log in to the Workspace ONE Access appliance as the root user.
  2. Open the /usr/local/horizon/conf/ file for editing.
  3. Change the read.only.service=true line to read.only.service=false.
  4. Change the cache.service.type=ehcache line to cache.service.type=rds.
  5. Save the file.
  6. Restart the Tomcat server on the appliance.
