You can configure a new Greenplum Database system with a standby coordinator using
gpinitsystem or enable it later using
gpinitstandby. This topic assumes you are adding a standby coordinator to an existing system that was initialized without one.
gpadminsystem user created, Greenplum Database binaries installed, environment variables set, SSH keys exchanged, and that the data directories and tablespace directories, if needed, are created.
gpinitstandby utility on the currently active primary coordinator host to add a standby coordinator host to your Greenplum Database system. For example:
$ gpinitstandby -s scdw
-s specifies the standby coordinator host name.
To switch operations to a standby coordinator, see Recovering a Failed Coordinator.
You can run the
gpstate utility with the
-f option to display details of the standby coordinator host.
$ gpstate -f
The standby coordinator status should be passive, and the WAL sender state should be streaming.
For information about the gpstate utility, see the Greenplum Database Utility Guide.
