• VMware Aria Automation Orchestrator Plug-in for Cloud Director 10.5.1

Cause

The issue occurs due to the change of JDK version used in Aria Automation Orchestrator (AAO) 8.17 and later releases.

Resolution

 

NOTE: Make sure to not override/modify/delete any existing configuration in the custom profile. Ensure these steps are verified in a Test environment before being applied to Production. These changes apply to the complete AAO server, and not just the AAO-VCD Plugin

 

1. Login to AAO server
2. Navigate to below location

cd /etc/vmware-prelude/profiles/custom-profile/helm/prelude_vco/

3. Edit the file '90-resources.yaml'.

If the  file '90-resources.yaml' does not exist.   1. Run the following command: vracli cluster exec -- bash -c 'base64 -d <<< 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 | bash' 2.
