Use database link (see http://docs.oracle.com/cd/B12037_01/server.101/b10759/statements_5005.htm) to read the DB in linux server. But as scott said, a Oracle DB must be in Windows to hold APEX and use DB link to target DB to connect.
You must ensure ports are opened and accessable from Windows DB, network ACL enabled (I think I got ACL related error last time I tried it)..etc.
