This reference lists and describes the environment variables to set for Greenplum - Database. Set these in your user's startup shell profile (such as ~/.bashrc or ~/.bash_profile), or in /etc/profile if you want to set them for all users.

- - - - Required Environment Variables - - GPHOME, PATH and - LD_LIBRARY_PATH can be set by - sourcing the greenplum_path.sh file from your Greenplum Database - installation directory - - - GPHOME - -

This is the installed location of your Greenplum Database software. For - example:

- GPHOME=/usr/local/greenplum-db-<version> -export GPHOME - - - - PATH - -

Your PATH environment variable - should point to the location of the Greenplum Database 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 Greenplum Database/PostgreSQL - library files. For example:

- LD_LIBRARY_PATH=$GPHOME/lib -export LD_LIBRARY_PATH - - - - MASTER_DATA_DIRECTORY - -

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

- MASTER_DATA_DIRECTORY=/data/master/gpseg-1 -export MASTER_DATA_DIRECTORY - - - - - Optional Environment Variables - -

The following are standard PostgreSQL environment variables, which are also - recognized in Greenplum Database. 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 Greenplum Database master 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 Greenplum Database master host name.

- - - - PGHOSTADDR - -

The numeric IP address of the master 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 Greenplum Database master - server.

- - - - PGPORT - -

The port number of the Greenplum Database server on the master host. The default - port is 5432.

- - - - PGUSER - -

The Greenplum Database 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...)
