I am searching for a query to get the Oracle Home for a particular instance name, say Eagle (if there are more than one instance on the host).

When you say "Oracle query", are you talking about a SQL statement? Or are you talking about a script that runs at the operating system level? The latter would seem much more reasonable. Are you assuming that the DBA didn't follow any sort of logical process in setting up the server? Or can we assume that things were configured logically?– Justin CaveCommented May 21, 2013 at 8:18

You can do this from a Unix shell, like so:
[oracle@node1 ~]$ grep "^YOURSID:" /etc/oratab | cut -d: -f 2
/u01/app/oracle/product/11.2.0/dbhome_1
[oracle@node1 ~]$

You can also do this by utilizing the v$parameter view. Assuming your spfile is saved under the oracle_home in the dbs/ folder, this is a rough query using functions within functions to get the oracle_home.
select substr(value, 1, length(value) - length(substr(value, instr(value,'dbs'))))
from v$parameter
where name = 'spfile';
