Hello All,

I'm new to Oracle Database.

I changed the password for sys user using

alter user SYS identified by "P@ssw0rd"

and tried to connect using the following command

sqlplus /nolog

SQL> connect sys as sysdba

Enter password:

ERROR:

ORA-12154: TNS:could not resolve the connect identifier specified

SQL>

how can I solve this error ?

Thanks & Regards
