How to login/reset password in oracle 11G database?

Question

Oracle

Good afternoon!
The problem is the following... Yesterday we changed the password from the SCOTT user, and in the settings of the utility that connected to the database, they forgot to set a new password, as a result, the user was blocked, and the password from SYS and SYSDBA was lost. Now I'm running into the same errors...
I log in as an admin, I'm in the ora_dba group, why can't I log in on command

connect / as sysdba

writes error ORA-01031: insufficient privileges
Tried to reset the SYS password using the command

orapwd

, then rebooted the server, but it didn't work, writes that the password is not correct ORA-01017...
ORACLE_HOME and ORACLE_SID are set, if this information is needed
I tried everything already, how to be? Waiting for the timeout to pass is also not an option, the database is urgently needed ... Help, please?

Answer 1

For information, in case someone needs it: Members of the group dba (unix) and ora_dba (win when using sqlnet.authentication_services=(NTS) in
sqlnet.ora) can log in locally under "/ as sysdba".
sec_case_sensitive_logon, that is, the software most likely can not access oracle with a password set in non-capital characters.In order to transfer nls_lang to 866, it is better to transfer the console to cp1251.mode
con: cp select=1251
The cmd font must be Truetype.
