DB Connect has differences in managing it on Splunk Cloud Platform Victoria Experience. This list presents those differences:

• Installing JDBC drivers other than served by JDBC Add-ons is not possible on Splunk Cloud Platform Victoria Experience. In case of necessity of having other drivers idea need to be create on Idea Portal
• Migrate from Single Instance of Splunk Enterprise to Search Head Cluster environment in Victoria Experience consider limitation described in Performance considerations in distributed environments.
• Splunk leaves the outbound ports on Splunk Cloud Platform Victoria Experience closed by default. It might prevent connecting to your database from Search Head with DB Connect installed. Follow the instructions to open the Outbound port from Search Head to your Database.
