restart

The restart command restarts components regardless of whether they're currently running or stopped.

Note: restart can't be run if start, stop, backup, or restore is currently running.
To restart components, run the following from the Admin Server: 
./bdd-admin.sh restart [option <arg>]

restart supports the following options.

Option Description
-t, --timeout <minutes> The amount of time to wait (in minutes) before terminating the component(s).

If this value is 0, the script forces the component(s) to shut down immediately. If it's greater than 0, the script waits the specified amount of time for the component(s) to shut down gracefully, then terminates them if they don't.

If this option isn't specified, the script shuts the component(s) down gracefully, which may take a very long time. If a component is down, a timeout value should be specified or the script will hang.

-c, --component <component(s)> A comma-separated list of the components to restart:
  • agent: Dgraph HDFS Agent
  • dgraph: Dgraph
  • dp: Data Processing
  • bddServer: Studio and Dgraph Gateway
  • transform: Transform Service
  • clustering: Clustering Service (if enabled)
Note the following:
  • Restarting bddServer requires the WebLogic Server username and password if the BDD_WLS_USERNAME and BDD_WLS_PASSWORD environment variables aren't set.
  • dp can't be restarted if bddServer is stopped.
  • agent can't be restarted if ZooKeeper isn't running.
-n, --node <hostname(s)> A comma-separated list of the nodes to run on. Each must be defined in bdd.conf.

If no options are specified, the script restarts all supported components gracefully.

Examples

The following command gracefully shuts down and then restarts all supported components: 
./bdd-admin.sh restart
The following command waits 5 minutes for the Dgraph and the HDFS Agent on the web009.us.example.com node to shut down gracefully, terminates it if it's still running, then restarts it: 
./bdd-admin.sh restart -t 5 -c dgraph -n web009.us.example.com
