Resolution

To resolve this issue, please follow these steps:

• Ensure you have a snapshot of the vIDM appliance before proceeding.
  
  
• Validate the permissions and ownership of files under the 'conf' folder by following the steps outlined in KB article 89301.
  
  
• Check for any database locks as described in KB articles 319309 and 370272.

 

If the issue persists after validating permissions and checking for database locks, proceed with the following steps:

• Validate the configuration in config-admin.json, idm-cacerts and system-config.properties files located in /usr/local/horizon/conf/.
  
  
  
  
• Use the ls -l command to check if these files are corrupted or have a size of 0KB.
  
  
• If corrupted or empty, copy the content from a working node to the corrupted node.
  
  
• Restart the HZN (Horizon) service by running the command: service horizon-workspace restart.
  
  

These steps should help in resolving the issue you are facing with the vIDM appliance.
