Required Environment Variables

Note GPHOME, PATH and LD_LIBRARY_PATH can be set by sourcing the greenplum_path.sh file from your WarehousePG installation directory

Parent topic: WarehousePG Environment Variables

GPHOME

This is the installed location of your WarehousePG software. For example:

GPHOME=/usr/edb/whpg7
export GPHOME

PATH

Your PATH environment variable should point to the location of the WarehousePG bin directory. For example:

PATH=$GPHOME/bin:$PATH
export PATH

LD_LIBRARY_PATH

The LD_LIBRARY_PATH environment variable should point to the location of the WarehousePG/PostgreSQL library files. For example:

LD_LIBRARY_PATH=$GPHOME/lib
export LD_LIBRARY_PATH

COORDINATOR_DATA_DIRECTORY

This should point to the directory created by the gpinitsystem utility in the coordinator data directory location. For example:

COORDINATOR_DATA_DIRECTORY=/data/coordinator/gpseg-1
export COORDINATOR_DATA_DIRECTORY

Optional Environment Variables

The following are standard PostgreSQL environment variables, which are also recognized in WarehousePG. You may want to add the connection-related environment variables to your profile for convenience, so you do not have to type so many options on the command line for client connections. Note that these environment variables should be set on the WarehousePG coordinator host only.

PGAPPNAME

The name of the application that is usually set by an application when it connects to the server. This name is displayed in the activity view and in log entries. The PGAPPNAME environmental variable behaves the same as the application_name connection parameter. The default value for application_name is psql. The name cannot be longer than 63 characters.

PGDATABASE

The name of the default database to use when connecting.

PGHOST

The WarehousePG coordinator host name.

PGHOSTADDR

The numeric IP address of the coordinator host. This can be set instead of or in addition to PGHOST to avoid DNS lookup overhead.

PGPASSWORD

The password used if the server demands password authentication. Use of this environment variable is not recommended for security reasons (some operating systems allow non-root users to see process environment variables via ps). Instead consider using the ~/.pgpass file.

PGPASSFILE

The name of the password file to use for lookups. If not set, it defaults to ~/.pgpass. See the topic about The Password File in the PostgreSQL documentation for more information.

PGOPTIONS

Sets additional configuration parameters for the WarehousePG coordinator server.

PGPORT

The port number of the WarehousePG server on the coordinator host. The default port is 5432.

PGUSER

The WarehousePG user name used to connect.

PGDATESTYLE

Sets the default style of date/time representation for a session. (Equivalent to SET datestyle TO...)

PGTZ

Sets the default time zone for a session. (Equivalent to SET timezone TO...)

PGCLIENTENCODING

Sets the default client character set encoding for a session. (Equivalent to SET client_encoding TO...)
