Upgrade to vRealize Orchestrator 7.6 (vRO) - Empty workflow output

Over the past few weeks I had to update quite a few instances of vRealize Orchestrator to version 7.6, where I experienced that upgraded instances do not show any workflow logs, or values anymore. My first thought was that the workflow was no longer executed, but actually it proofed to be a display problem in the vRealize Orchestrator Client. While talking to a few friends working near the product I got some guidance on how to potentially solve the issue...

The approach I received from VMware support was to manually move my workflows etc. from 7.5 to 7.6 instead of upgrading, which was why I researched the following solution.

However be warned: This is not an official supported solution, while I don't see any issues with it I can't guarantee that you are still supported afterwards.


  1. Login at the console or via SSH into your vRealize Orchestrator appliance with root credentials.
  2. Stop the Orchestrator Service
  3. service vco-server stop
  4. Remove all lucene log files

  5. rm -rf /var/log/vco/app-server/scripting.log_lucene*
  6. Start the orchestrator service

  7. service vco-server start
  8. Logout from the console / ssh session

Everything should be good again.
