I don't know, my luck with that view has been sort of hit and miss. As the others have noted the information is just not there or a place holder of some sort. It's really up to the client software that you are using to pass that information on to the server. For instance if I access 11.2 from a 9i client the client_verson is populated with 0.0.0.0. However, if I access 11.2.0.3 from a 11.2.0.1 (windows) client I get the following: $ sqlplus andy/andy@oimt1 SQL*Plus: Release 11.2.0.1.0 Production on Thu Jan 19 16:13:27 2012 Copyright (c) 1982, 2010, Oracle.
