Local Registry (dbConfig name="wso2registry") in the registry.xml file is by default pointing to the CARBON_DB. Local registry stores individual node specific data so it should not be shared across other nodes in the cluster. Ideally you can use embedded H2 for the local registry, however if you want to setup mysql then you have to setup mySQL DB per each node. > > governance and configuration registries will be in a unique and shared > DB > Governance and config registries contain data that needs to be shared across all the nodes in the cluster so they should be pointing to a single database from all the nodes. Please refer 'Mounting the registry' section in [1] to understand further regarding this.
