Hello,

I have a problem with an Oracle application. Since i demoted domain controller on a server (Windows Server 2003), the application doesn't start. The error message appears : ORA-12505 tns listener does not currently know of sid given in connect descriptor.

I don't know Oracle but i searched without finding any solutions.

On the client computer, i found a tnsnames.ora file :

# C:\ORAWIN95\NET80\ADMIN\TNSNAMES.ORA Configuration File:C:\orawin95\net80\admin\tnsnames.ora

On the server computer i found a tnsnames.ora file too :

# tnsnames.ora Network Configuration File: D:\oracle\HomeVega10G\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

GIMA =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.5)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = GIMA)
)
)

(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = GIMA)
)
)

I found a listener.ora file on the server :

# listener.ora Network Configuration File
# Generated by Oracle configuration tools

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = d:\oracle\HomeVega10g)
(SID_NAME = VEGA)
)
)


LISTENER =
(DESCRIPTION =
(ADDRESS =
(PROTOCOL = TCP)
(HOST = 192.168.10.5)
(PORT = 1521)
)
)


The services on the server :

OracleCSService (not started) Manual : i cannot start this service.
OracleJobSchedulerGIMA (started) Automatic
OracleJobSchedulerVEGA (started) Automatic
OracleOracleHomeVega10gSNMPPeerEncapsulator (not started) Manual

OracleOracleHomeVega10gTNSListener (started) Automatic
OracleOracleHomeVega10gTNSListenerGIMA (not started) Manual : i cannot start this service (it starts and stop immediately).
OracleServiceGIMA (started) Automatic


For information :

Application name : GIMA
Server ip address : 192.168.10.5
Ping server since client computer : OK (ip address and name).
No firewall on the client computer and server.
No antivirus.
Telnet 1521 on the server OK.
There is another application named VEGA on the server and there is no problem with this application.

Can you help me please ?

PS : Sorry for my English, i don't speak English very well !
