DBI connect to Intersystems Cache db

I need assistance setting up a DBI:ODBC connection to an Intersystems
Cache’ db. The db is across the network; it’s not on my machine.
Frankly, I’m struggling with what to code for the dbi connect.

DBI.connect(‘DBI:ODBC:[What goes here?]’, ‘user’, ‘password’) {|db|


I don’t know what to code for the database name. Any pointers? I’ve
tried using the cacheodbc.dll file name, the system dsn name from the
MS ODBC Administrator. It shows how clueless I am.

Thanks for any and all assistance.
