I have forgotten my Oracle username and password and hence not able to use it. My Oracle version is 11.2.0.1.0(11g). I consulted Internet. They asked me to execute commands
Go to SQL command line:- type:
sql>connect / as sysdba;
then type:
sql>desc dba_users;
then type:
sql>select username,password from dba_users;
If sysdba doesn't work then try connecting with username:scott and password: Tiger
You will be able to see all users with passwords. Probably you might find your's. Hope this helps
