Getting ORA-01017: invalid username/password in non-CDB database

oracleoracle-12c

I have installed Oracle 12c (software only in Linux) and created a non-CDB database (single tenant) database. Following is my listener.ora.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ora12cl)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )
SID_LIST_LISTENER=
(SID_LIST=
  (SID_DESC=
    (SID_NAME=orcl)
    (GLOBAL_DBNAME=orcl)
  )
)

This is my tnsnames.ora

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ora12cl)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SID = orcl)
    )
  )

Here is my initorcl.ora

db_name=orcl
db_block_size=8192
memory_target=300M
memory_max_target=300M
processes=200
job_queue_processes=10
open_cursors=500
fast_start_mttr_target=500
undo_management=AUTO
undo_tablespace=UNDOTBS1

I am able to startup and mount the database successfully. I can connect to it 

 [oracle@ora12cl dbs]$ sqlplus sys/***** as sysdba

But if I try to connect using the instance (as I should from a remote system such as my Windows host):

[oracle@ora12cl dbs]$ sqlplus sys/dolan123 as sysdba

I am getting ORA-01017.

I see no reason why should not able to login using the instance name. Note it's a non-CDB database. 

[oracle@ora12cl dbs]$ sqlplus / as sysdba

Can anyone help on this please?

Best Answer

Remote (through listener) SYSDBA authentication requies a passwordfile.

  1. Make sure remote_login_passwordfile is set to EXCLUSIVE or SHARED.

  2. Create the password file at ${ORACLE_HOME}/dbs/orapw${ORACLE_SID} as:

orapwd file=${ORACLE_HOME}/dbs/orapw${ORACLE_SID}

This will prompt for a password, then it will create the password file. After that, you can log in remotely as SYSDBA.

PS:

This version uses OS authentication:

$ sqlplus sys/dolan123 as sysdba

As long as you try connecting locally as SYSDBA with a user that is member of the OSDBA group (defined at install time, typically dba), you can type any password, because you will be authenticated based on your group membership, not the password. Successfully logging in with the above does not necessarily means that the SYS password is dolan123.
