Investigating Client System Configuration
This appendix introduces advanced considerations for configuring ODBC drivers and data
sources on Linux/UNIX client systems, with respect to locating the .odbcinst.ini and
.odbc.ini configuration files.
Netezza ODBC Driver
This section discusses the names and locations of the two ODBC configuration files. You
can configure the two ODBC configuration files as hidden files or as non-hidden files, and
you can place them in directories other than in the user’s home directory.
The ODBC configuration examples for Linux/UNIX systems in Chapter 5 configure the two
ODBC configuration files as hidden files by preceding their names with an initial “.” char-
acter. You can alternatively configure them as non-hidden files by omitting the initial “.”
character.
Hidden Files. When you place the two ODBC configuration files in the user’s home
directory, the Netezza ODBC driver expects the files to have the hidden file names
.odbcinst.ini and .odbc.ini.
Non-Hidden Files. When you place the two ODBC configuration files in a directory
other than the user’s home directory, the Netezza ODBC driver expects the files to have
the non-hidden file names odbcinst.ini and odbc.ini.
ODBC Driver Search Behavior
The default behavior of the Netezza ODBC driver is to search the following places, in
sequence, to locate the two ODBC configuration files:
1. If there is an NZ_ODBC_INI_PATH entry in the environment describing a directory
path, the driver looks first in that directory for two non-hidden configuration files.
2. The driver then looks in the current user’s home directory for the two hidden files:
.odbcinst.ini and .odbc.ini. If the two configuration files exist as non-hidden
files in the user’s home directory, the driver ignores them.
