good day!

i'm confronted with the following situation

  • OS: CentOS 7 x86_64

  • user: oracle (member of DBA group, owner of /u01/app (drwxr-sr-x)

  • /etc/oratab: orcl12c:/u01/app/oracle/product/12.1.0/dbhome_1:Y

  • after starting LISTENER manually, Listener reports "The listener supports no services"

  • sqlplus sys/*@co7ora12cvm:1521/orcl12c as sysdba returns «ORA-12514: TNS:listener does not currently know of service requested in connect descriptor»

  • dbstart starts listener but errors out with ORA-01017: invalid username/password; logon denied

  • i'm able to start the database through dbca (Configure database options > Next > Next)

  • once this is done LISTENER know of the services orcl12c and orcl12cXDB

  • once this is done, sqlplus username@orcl12c works fine

  • sqlplus as sysdba throws the /? output.

  • ping co7ora12cvm works

  • tnsping orcl12c times out (TNS-12535)

listener.ora LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = co7ora12cvm)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) )

shrept.lst (##) function entry points for genclntsh.sh

network : snaumihi_inithostinfo network : snaumbg_gmt network : naedpwd_encrypt network : naumbsb_bld_singlebyte network : nlgh network : nsdhctx_establish network : nsdhctx_respond network : nsdhctx_close network : nsdhctx_inuse network : snlsmDscFromString network : snlsmCreate network : snlsmDestroy network : snlsmDscToString

sqlnet.ora SQLNET.AUTHENTICATION_SERVICES = (NONE)

tnsnames.ora ORCL12C = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = co7ora12cvm)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl12c) ) )

this is a new install that has never started "normally"

thanks in advance for any suggestion

############# UPDATE user/hosts

as already mentioned i do this as user oracle which is member of the dba team

this is run on vmware and i do the networking with the hosts files

/etc/hosts on co7ora12vm 127.0.0.1 localhost.localdomain localhost 192.168.178.30<>co7ora12cvm.localdomain co7ora12cvm

c:\windows\System32\drivers\etc\hosts (on Windows 7) 192.168.178.30 co7ora12cvm.localdomain co7ora12cvm

############# UPDATE sqlnet.ora

thanks for spotting this, indeed, alas it makes no difference

  • sqlplus sys/sys@co7ora12cvm:1521/orcl12c as sysdba gives ORA-12514: TNS:listener does not currently know of service requested in connect descriptor before instance is started through dbca; once instance is started it connects

  • sqlplus / as sysdba always gives ORA-12162: TNS:net service name is incorrectly specified

this happens no matter what sqlnet.ora contains

  • SQLNET.AUTHENTICATION_SERVICES = ()

  • SQLNET.AUTHENTICATION_SERVICES = (NONE)

  • NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT) such as on my 10g vm where sqplus / as sysdba works

?

  • Is co7ora12cvm in /etc/hosts or DNS? What Unix user are you trying to do this as, and are they in the correct group? Did you install with a pdb/cdb? – Philᵀᴹ Oct 16 '15 at 11:39

You have disabled local OS authentication by setting this:

SQLNET.AUTHENTICATION_SERVICES = (NONE)

Remove the above line from sqlnet.ora, after that, you will be able to log in to the database with:

sqlplus / as sysdba

  • Good bit of detective work :-) – Philᵀᴹ Oct 16 '15 at 12:59
