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
