I have installed oracle database 11g enterprise edition but when I go to the "get started" section, I get stopped by a login screen. How do I find out my credentials, it doesn't appear to be the same credentials as the oracle website sign in?
Same credential as specified in the installer, if you're looking at the apex admin page ...:8080/apex/f?p=4950 try system for the login, password the value that was entered in the installer dialog box ...
you're posting in the express edition forum but are talking about enterprise edition.... there are major differences between them. I assume your using XE ( express edition ).
When asked for a login this should be a database account. During installation at least 2 accounts are created. User sys and system
Both of them have a password which you entered during installation ( check http://docs.oracle.com/cd/E17781_01/install.112/e18803.pdf )
If you forgot those there are ways to recover from that ( start sqlplus and connect as internal, change the passwords of those users and try again ), but a reinstall and writing down the passwords might also be an option if your not familiar with oracle yet :)
