Node command-line options
The node can optionally be started with the following command-line options:
--base-directory,-b: the node working directory where all the files are kept (default:.).--config-file,-f: the path to the config file. The path can be absolute or relative to the base directory. Defaults tonode.conf.--dev-mode,-d: runs the node in development mode. Unsafe in production. Defaults to true on MacOS and desktop versions of Windows. False otherwise.--no-local-shell,-n: do not start the embedded shell locally.--on-unknown-config-keys <[FAIL,INFO]>: how to behave on unknown node configuration. Defaults to FAIL.--sshd: enables SSH server for node administration.--sshd-port: sets the port for the SSH server. If not supplied and SSH server is enabled, the port defaults to 2222.--verbose,--log-to-console,-v: if set, prints logging to the console as well as to a file.--logging-level=<loggingLevel>: enable logging at this level and higher. Possible values: ERROR, WARN, INFO, DEBUG, TRACE. Default: INFO.--help,-h: show this help message and exit.--version,-V: print version information and exit.--allow-hibernate-to-manage-app-schema: enable this option to make the node manage app schemas automatically using Hibernate with H2 in dev mode.
[COMMAND] precedes all options. Failing this, the provided arguments will not be in scope for the command and default arguments will be used instead as a result. For example, if -f custom_config.conf precedes the [COMMAND], Corda will look for the default node.conf instead of the specified custom_config.conf.Sub-commands
clear-network-cache: clears the local copy of the network map. On node startup it will be restored from the server or the file system.
initial-registration: starts the initial node registration with the compatibility zone to obtain a certificate from the Identity Manager Service.
Important note about running the initial node registration command
In Corda 4.6, database schemas are no longer initialised/migrated automatically by running any command at the first run of the node - typically at the initial node registration. This is now done explicitly by running run-migration-scripts, so no other commands during the first node run would initialise/migrate the database schema.
The exception to that is the --initial-registration command, which embeds run-migration-scripts and therefore runs the database migration scripts by default.
So if you are using deployment automation you may need to adjust your scripts accordingly and exclude the database initialisation/migration task from the initial node registration command. To do so, use the --skip-schema-creation flag alongside the --initial-registration command.
Parameters:
--network-root-truststore,-trequired: Network root trust store obtained from network operator.--network-root-truststore-password,-p: Network root trust store password obtained from network operator.--skip-schema-creation: Skips the default database migration step.
run-migration-scripts: from version 4.6, a Corda node can no longer modify/create schema on the fly in normal run mode - schema setup or changes must be
applied deliberately using this sub-command. It runs the database migration script for the requested schema set defined in the following parameters. Once it creates or modifies the schema(s), the sub-command will exit.
Parameters:
--core-schemas: use to run the core database migration script for the node database. Core schemas cannot be migrated while there are checkpoints.--app-schemas: use to run the app database migration script for CorDapps. To force an app schema to migrate with checkpoints present, use the--update-app-schema-with-checkpointsflag alongside therun-migration-scriptssub-command.
generate-node-info: Performs the node start-up tasks necessary to generate the nodeInfo file, saves it to disk, then exits.
generate-rpc-ssl-settings: Generates the SSL keystore and truststore for a secure RPC connection.
install-shell-extensions: Install corda alias and auto completion for bash and zsh. See
Shell extensions for CLI Applications for more info.
validate-configuration: Validates the actual configuration without starting the node.
Enabling remote debugging
To enable remote debugging of the node, run the node with the following JVM arguments:
java -Dcapsule.jvm.args="-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005" -jar corda.jar
This will allow you to attach a debugger to your node on port 5005.
