Hi all,

1) I have created a new database called 'oct'.
The database was opened, however, I was not able to log into 'database' 'OCT' using sqlplus.
a)Which user id and password, should I use to get into this new data base?.

2). As I could not get into 'oct', I tried connecting back using the default 'ORCL' database after changing the ORACLE_SID to ORCL and all other parameters being same.

Now, I am unable to get into even SVRMGR, Oracle gives
ORA-12203: TNS:unable to connect to destination.

I have checked up the listner(It's running) and all other files are in its place.
Please advice
