org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update
Patch level detected:Univiewer Management Server 6.2.00
After the upgrade from DUAS v5 to v6 on the UVC console the node appears with the Unknown connection status but it was reachable and objects / node settings could be displayed.
On UVC - UVMS Database Monitoring section is not possible to display the database tables
The UVMS was on version 6.2 with an external Database (MS SQL Server).
Root Cause: A problem in the UVMS Database would not allow the modiification of the table UNI_UV_NODES
Restarting the UVMS allows to update again the impacted line of the table UNI_UV_NODES, as a result the node appeared as Connected again.
Fix Status: No Fix
