Description

The pxf utility manages the PXF configuration and the PXF Service instance on the local Greenplum Database host. You can use the utility to:

• Synchronize the PXF configuration from the coordinator host to the standby coordinator host or to a segment host.
• Start, stop, or restart the PXF Service instance on the coordinator host, standby coordinator host, or a specific segment host, or display the status of the PXF Service instance running on the coordinator, standby coordinator, or a segment host.
• Copy the PXF extension control file from a PXF installation on the host to the Greenplum installation on the host after a Greenplum upgrade.
• Prepare a new $PXF_BASE runtime configuration directory on the host.

(Use the pxf cluster command to prepare a new $PXF_BASE on all hosts, copy the PXF extension control file to $GPHOME on all hosts, synchronize the PXF configuration to the Greenplum Database cluster, or to start, stop, or display the status of the PXF Service instance on all hosts in the cluster.)

Commands

cluster

Manage the PXF configuration and the PXF Service instance on all Greenplum Database hosts. See pxf cluster.

help

Display the pxf management utility help message and then exit.

init (deprecated)

The command is equivalent to the register command.

migrate

Migrate the configuration in a PXF 5 $PXF_CONF directory to $PXF_BASE on the host. When you run the command, you must identify the PXF 5 configuration directory via an environment variable named PXF_CONF. PXF migrates the version 5 configuration to the current $PXF_BASE, copying and merging files and directories as necessary.

Note: You must manually migrate any pxf-log4j.properties customizations to the pxf-log4j2.xml file.

prepare

Prepare a new $PXF_BASE directory on the host. When you run the command, you must identify the new PXF runtime configuration directory via an environment variable named PXF_BASE. PXF copies runtime configuration file templates and directories to this $PXF_BASE.

register

Copy the PXF extension files from the PXF installation on the host to the Greenplum installation on the host. This command requires that $GPHOME be set, and is run once after you install PXF 6.x the first time, or run when you upgrade your Greenplum Database installation.

reset (deprecated)

The command is a no-op.

restart

Restart the PXF Service instance running on the local coordinator host, standby coordinator host, or segment host.

start

Start the PXF Service instance on the local coordinator host, standby coordinator host, or segment host.

status

Display the status of the PXF Service instance running on the local coordinator host, standby coordinator host, or segment host.

stop

Stop the PXF Service instance running on the local coordinator host, standby coordinator host, or segment host.

sync

Synchronize the PXF configuration ( $PXF_BASE) from the coordinator host to a specific Greenplum Database standby coordinator host or segment host. You must run pxf sync on the coordinator host. By default, this command updates files on and copies files to the remote. You can instruct PXF to also delete files during the synchronization; see Options below.

version

Display the PXF version and then exit.

Options

The pxf sync command, which you must run on the Greenplum Database coordinator host, takes the following option and argument:

–d | ––delete

Delete any files in the PXF user configuration on <gphost> that are not also present on the coordinator host. If you specify this option, you must provide it on the command line before <gphost>.

<gphost>

The Greenplum Database host to which to synchronize the PXF configuration. Required. <gphost> must identify the standby coordinator host or a segment host.

Examples

Start the PXF Service instance on the local Greenplum host:

$ pxf start
