Hello to all!
I recently installed Oracle XE 11.2 on CentOS 6.3. Shortly after installation, the http://localhost:8080/apex worked perfectly. After the first reboot after installation of Oracle XE 11.2, the http://localhost:8080/apex stops working. After much searching, I found that opening the file /etc/sysconfig/network and re-record it, without changing anything, it solves the problem.
I can not explain. If anyone knows please explain, help me to keep it permanently in the system.
Thak you all!
