I'm currently working on a uni project using Oracle and having no previous experiance....I'm already stuck!
I have install Oracle and setup a default database and connect using the http://localhost:5500/em
However I get the intermitent probs (seems to be when I reboot), the em console page reoprts:
The database status is currently unavailable. It is possible that the database is in mount or nomount state. Click 'Startup' to obtain the current status and open the database. If the database cannot be opened, click 'Perform Recovery' to perform an appropriate recovery operation.
When I click startup and put in the user/pass info I get the error:
Io exception: The Network Adapter could not establish the connection
and asks me to confirm that I would like to shutdown the database (current status indicates open).
The only way that I have found to get rid of this problem is to completely uninstall then re-install oracle!!!
Any ideas anyone??!
