I am new to Oracle and am using it in my Info class at college. When I uninstalled the application and reinstalled it and clicked on the application to load Oracle internet explorer suddenly now displays "Internet Explorer cannot display webpage."
I've reinstalled about 9 times now. I've tried starting and stopping the database and attempted to find other similar problems to help fix it.
When I try to connect via the sql command line I get
ORA-01034 Oracle not available
ORA-27101 shared memory realm not available.
If anyone knows whats wrong it would be greatly appreciated and if you need anymore info I'd be more than happy to give it. Remember I'm pretty new to this and may need an explanation on where to go to do what.
I have had the similar problem before few days ago...
Please check the directory \ORA_HOME\app\oracle\product\11.2.0\server\dbs\
I didn't have file SPFILEXE.ORA after installation (But I didn't get any error message during installation).
I had to uninstall Oracle XE and clean registry keys.
Then I reinstall it and it works correctly.
