Hi,
I'm using Oracle 11g database Version 11.2.0.1.0 and this problem im having seems not to get solved on my system...
Im working directly with the computer Oracle is installed and i have tried all solutions i could find on the OTN forum for the ORA-01034 error, but none seemed to work for me please anyone have anymore ideas?
EXPLANATION: first i had this ORA-12505, so i applied a solution from OTN forum by editing the listener.ora file and added one more SID_DESC and it seemed to solve the ORA-12505 error, after which i reboot my system and tried connecting, instead a new error appeared ORA-01034.
This is what my listener.ora file looks lik after i edited it:

# listener.ora Network Configuration File: C:\app\OBI\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\app\OBI\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\app\OBI\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = obyys)
(ORACLE_HOME = C:\app\OBI\product\11.2.0\dbhome_1)
(SID_NAME = obyys)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)

ADR_BASE_LISTENER = C:\app\OBI

This is my tnsnames.ora file:

# tnsnames.ora Network Configuration File: C:\app\OBI\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)

OBYYS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = obyys)
)
)

These are the solutions i tried out for the 0RA-01034 BUT NONE WORKED
1) do you find in your sqlnet.ora an entry like SQLNET.AUTHENTICATION_SERVICES=(NTS)? If so, change it on trial to SQLNET.AUTHENTICATION_SERVICES=(NONE) .
2) set oracle_sid = grms
sqlplus /nolog
conn system/manager as sysdba
shutdown abort
startup
3) changing the service name to CAPS
Please anyone have any other better ideas.. would appreciate. Thanks
