- Next Steps
See the Greenplum Database Release Notes for the list of currently supported platforms for the Load Tools.
Running the Load Tools Installer
The Greenplum Database load tools installer installs the following data loading tools:
To install the Greenplum Database load tools
- Download the appropriate greenplum-loaders-4.3.x.x-PLATFORM.bin.zip installer package for your platform from Pivotal Network.
- Unzip the
- Run the
- The installer will prompt you to accept the license agreement and to provide an installation path. For the installation path, be sure to enter an absolute path if you choose not to accept the default location (for example, /mydir/gp-loader-tools). The load tools are installed into greenplum-db-4.3.x.x by default.
About Your Installation
Your Greenplum Database load tools installation contains the following files and directories:
- bin — data loading command-line tools and library files (gpfdistand gpload)
- docs — documentation files
- greenplum_loaders_path.sh — environment variables
Configuring the Command-Line Load Tools
- GREENPLUM_LOADERS_HOME — The installation directory of the Greenplum Database load tools.
- PATH — The path to the data loading command-line utilities.
- LD_LIBRARY_PATH — The path to additional Python library files needed for gpload.
You can source this file in your user's startup shell profile (such as .bashrc or .bash_profile).
For example, you could add a line similar to the following to your chosen profile files (making sure the right install path is used):
After editing the chosen profile file, source it as the correct user to make the changes active. For example:
Additional Connection Environment Variables
The Greenplum load tools require several connection parameters in order to be able to connect to a Greenplum Database instance. In order to save some typing on the command-line, you can create the following environment variables in your preferred profile file (such as .bashrc).
- PGDATABASE — The name of the default Greenplum database to connect to.
- PGHOST — The Greenplum master host name or IP address.
- PGPORT — The port number that the Greenplum master instance is running on.
- PGUSER — The default database role name to use for login.
Enabling Greenplum Database for Remote Client Connections
In order for Greenplum Database to be able to accept remote client connections, you must configure your Greenplum Database master so that connections are allowed from the client hosts and database users that will be connecting to Greenplum Database.
To enable remote client connections
- Make sure that the pg_hba.conf file of the
Greenplum Database master is correctly configured to allow connections from
the users to the database(s) using the authentication method you want. For
details, see "Editing the pg_hba.conf File" in the Greenplum Database
Administration Guide, and also see the Greenplum Database
Security Configuration Guide.
Make sure the authentication method you choose is supported by the client tool you are using.
- If you edited pg_hba.conf file, the change requires a server reload (using the gpstop -u command) to take effect.
- Make sure that the databases and roles you are using to connect exist in the system and that the roles have the correct priviliges to the database objects.
