Looks like this connection is using OS authentication. Because if I provide wrong password for sys user still connection works.

Any help why with ORACLE_SID sys user connection is not working?

In my database sec_case_sensitive_logon parameter is set to false.

SQL> show parameter sec_case_sensitive_logon

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
sec_case_sensitive_logon             boolean     FALSE

Following was the root cause:

remote_login_passwordfile parameter was set to EXCLUSIVE

SQL> show parameter remote_login_passwordfile

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
remote_login_passwordfile            string      EXCLUSIVE

REMOTE_LOGIN_PASSWORDFILE specifies whether Oracle checks for a password file.

For me password file was missing.

Created password file

orapwd file=$ORACLE_HOME/dbs/orapw<sid> password=<password> force=y ignorecase=n

Bounce database.

Then Oracle sys user database connection with ORACLE_SID is working.

sqlplus sys/manager@dev  as sysdba
