Hi lists, I have this problem accessing apex in my 11.2.0.2 DB in Centos Linux, when I try to access the page http://1.1.1.1:8090/apex I get error could not to connect to address 1.1.1.1:8090. This is the setup in the DB: dispatchers = "(PROTOCOL=TCP) (SERVICE=MYDBXDB)" shared_servers = 10 local_listener = "(ADDRESS=(PROTOCOL=TCP)(HOST=dbserver)(PORT=1521))" The output of lsnrctl stat is: LSNRCTL for Linux: Version 11.2.0.2.0 - Production on 08-JUN-2014 11:12:33 Copyright (c) 1991, 2010, Oracle.

In the Oracle DB I have 2 IP address each point to a different ports. I don't know why the XDB service is not showing UP in the lsnrctl stat and I suppose that's why I cant connect to APEX.
