To install your new DataDirect Driver Manager and Greenplum driver:

1) Download and save the tar file 'xxxgpl###.tar' (where xxx = platform and ### = version) to the Unix box where SAS is installed.

2) Move the file to the directory where you want the driver to reside.

WARNING:  Do not install these drivers into an existing directory that contians your current drivers.  It can overwrite important files like odbc.ini and odbcinst.ini.  The recommended way is to create a complete new directory to install into.  Once you are done installing and configuring these drivers you can move your current driver directory and rename this one if necessary.

3) Run the following unix command (example is for Greenplum on Linux x64):

unix_prompt=> tar -xvf laxgpl712.tar

4) This will create a main directory with the platform name and below that a couple of files and some subdirectories.  You will need to update your libary path to point to the new "lib" subdirectory.

5) The environment variable LIBPATH(AIX), LD_LIBRARY_PATH(Solaris and Linux), or SHLIB_PATH(HPI) will need to be exported to pick up the changes.  For example, if you are currently on AIX your export command may look something like this:

unix_prompt=> export LIBPATH=/usr/local/gpl712/lax/lib:$LIBPATH

6) Included in the tar file are sample files called 'odbc.ini' and 'odbcinst.ini'.  These can be modified to add your DSN entries.

As a minimum you should update the following entries:

ODBC.INI
  -- InstallDir
  -- TraceDll
  -- Driver
  -- Database
  -- HostName
  -- PortNumber

ODBCINST.INI
  -- Driver

7) Export the environment variable 'ODBCINI' to point your 'odbc.ini' file.

unix_prompt=> export ODBCINI=/usr/local/gpl712/lax/odbc.ini

8)  Export the environment variable 'ODBCINST' to point your 'odbcinst.ini' file.

unix_prompt=> export ODBCINI=/usr/local/gpl712/lax/odbcinst.ini

9) Export the environment variable 'ODBCHOME' to point to your new directory.

unix_prompt=> export ODBCHOME=/usr/local/gpl712/lax

10) It is recommended you use the 'sasenv_local' file for most environment variables needed by SAS.  Adding 'LIBPATH'(AIX), 'LD_LIBRARY_PATH'(Solaris or Linux), or 'SHLIB_PATH'(HPI), 'ODBCINI', 'ODBCINST', and 'ODBCHOME' environment variables to the !SASROOT/bin/sasenv_local will make these environment variables global to all users who run SAS.
