To find the configuration files (odbc*.ini), issued:
sudo find / -name odbc*.ini 2>/dev/null
Upon issuance, received the file listing pasted below:
Did not have a clue which of these files is being used, so Googled for help:
Apple Mac OS/X
When you use the iODBC ODBC Administrator tool, the odbcinst.ini and the odbc.ini files are typically located in the /Library/ODBC directory if the driver or datasource was installed system-visible. If the driver or datasource was installed to be user-visible, the odbcinst.ini and the odbc.ini files are in the $HOME/Library/ODBC directory.
At runtime, the iODBC Driver Manager searches for DSN information in $HOME/Library/ODBC/odbc.ini. If your DSN information is in /Library/ODBC/odbc.ini or in any other location, you need to set an environment variable called ODBCINI to the path to the odbc.ini file.
setenv ODBCINI full pathname to the odbc.ini file
It seems the /Library/ODBC files are used by iODBC.
Here is a sample odbc.ini file:
[ODBC Data Sources] DBHR = jtds-1.3.0 [DBHR] Driver = /Users/bsmith/Downloads/jtds-1.3.0-dist/jtds-1.3.0.jar Description = DBHR
More about iODBC can be gleaned from here.
Just started reading up a bit on Homebrew. And, so this is still a bit in short-term memory.
It seems that folders underneath the /usr/local/Cellar/ folder are homebrew’s installs.
Furthermore /usr/local/Cellar/unixodbc/2.3.1 is unixodbc version 2.3.1
Changing Folder to /usr/local/etc and performing a quick ls revealed that the *.ini files in that folder are all symbolic links to aforementioned Cellar files.
That is, as long as Homebrew Installs are present and good we are OK.
