Cant logging on to oracle
 

Hi
I've installed oracle-xe on ubuntu(vmware) but when trying to login to oracle home page as 'system' or 'sys' i receive an 'invalid login credentials' message. I'm sure the password is correct (re-installed oracle to make sure it was correct!).
Any suggestions?
thx a lot

Same problem
 

Hi all
I have exactly the same problem, same type of installation, same error of login credentials (but what's simpler than typing sys with password admin). Same problem occurs when launching she SQL line console (insufficient credentials). A watch lsof -i command shows oralistener on port 1521 (default value). What's going wrong here ?

Oh yes, what's strange : trying to connect with another profile (the well known "hr"), I do get the message that hr's account is locked (which is normal), but does this mean that the login credentials really don't match (?!?!?). Or is their another Linux feature (rights on file) that block access ?

Thanks

Run sqlplus from ur oracle user and login as 'sys as sysdba'
also make sure that listener is running by typing 'lsnrctl status'.. if not started then type 'lsnrctl start'

It is now working.
I removed the virtual machine and create a new one; loaded Ubuntu 7.10 on it (previously I had 7.04), updated it,
and finally installed oracle 10g; configured it and it did work this time.

The differences with my two previous attempts were these 2:

1) Ubuntu 7.10 instead of 7.04
2) Created the appropriate swap space before receiving the error during the installation

thanks

Hey guys,
