I already success install oracle-xe on my ubuntu 10-04, tried to configure the port and password sudo /etc/init.d/oracle-xe configure, and then restart my computer and go to http://127.0.0.1:8080/apex and input system as the username and my password admin but it said that Invalid Login Credentials.
The problem here I cannot login, try to re-install the oracle but same problem occur. Anyone can help me with this things? I'm very appreciated your help, thanks...
