Starting Greenplum Database

The database initialization process (gpinitsystem) will start your Greenplum Database system for you once it has completed successfully. However, there may be times when you will need to restart the system, for example to reset operational configuration parameters or to troubleshoot a failed segment.
Use the gpstart utility to start your Greenplum Database system. This utility starts all of the postgres database listener processes in the system (the master and all of the segment instances). gpstart is always run on the master host.

Each instance is started in parallel (up to 60 parallel processes by default).

To start Greenplum Database

$gpstart

Restarting Greenplum Database

The gpstop utility has a restart option that will restart the Greenplum Database system once a successful shutdown has completed.

To restart Greenplum Database
$ gpstop -r
