I am having some troubles connecting to a remote DB view SQLPLus 8.1.7. I belive that the remote DB has recently put a firewall in front of it but I am able to get the machine via ftp. I have been told by the remote side that I should have access on all appropriate ports.
I need to verify that I have not done something stupid on my end. I have been able to connect to this machine before approx 2 weeks ago via SQLPlus and the listener is running.
While reading previsou messages I decided to try the log and trace abilities and got the following results. from the listener.trc file:
nncpmlf_make_local_addrfile: construction of local names file failed
nncpmsf_make_sys_addrfile: system names file is E:OracleOra81networkadmintnsnames.ora
nscall: connecting...

nsopen: unable to open transport
And I got the following in the client.trc file:
nigini: Count in NI global area now: 1
nigini: Count in NI global area now: 1
nrigbni: Unable to get data from navigation file tnsnav.ora

nioqper: nt OS err code: 0
niqme: reporting NS-12535 error as ORA-12535

I am totally in the dark here about what is happening. I really feel that it must be the changes on thier side but I cant confirm that. I was hoping someone here could help me figure a way to determine where the breakdown is happening.

If you can tnsping the database it isn't the firewall. Oracle suggests this if tnsping works:
Intermittent ora-12535 is usually an indication that the requested connection could not be completed within the timeout period specified by the CONNECT_TIMEOUT parameter in the LISTENER.ORA file.
The suggested solutions include:
1. Setting the connect_timeout_listener_name parameter in listener.ora to 0.
2. Setting up a second listener in a different port.
If this doesn't work log a tar.
If tnsping doesn't work I would ask them if they have allowed port 1521 passage through the firewall.

No put it here:
LISTENER =
(DESCRIPTION =
(CONNECT_TIMEOUT=30)(ADDRESS = (PROTOCOL = TCP)(HOST = server)(PORT = 1521))
)
Are you able to tnsping the database. Go to a DOS window and type "tnsping fire"?

I finally got confirmation from the remote side that firewall port 1521 is open. I attempted a telnet session to the server specifying port 1521 and got a connection. But I still can not get through with SQLPlus. I have included my current listener file below, is the timeout set up correctly? What is a tar?
This is my current listener.ora file:
LISTENER =
(DESCRIPTION =
(CONNECT_TIMEOUT = 0)(ADDRESS = (PROTOCOL = TCP)(HOST = server)(PORT = 1521))
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = E:OracleOra81)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = fire)
(ORACLE_HOME = E:OracleOra81)
(SID_NAME = fire)
)
)
TRACE_LEVEL_LISTENER=USER
TRACE_FILE_LISTENER=LISTENERtrace
TRACE_DIRECTORY_LISTENER = e:OracleOra81networktrace
Then my tnsnames.ora file is:
EXTPROC_CONNECTION_DATA.FIREPOPPY.COM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
SHOP1.FIREPOPPY.COM =
(DESCRIPTION =
(ADDRESS_LIST =
(CONNECT_TIMEOUT=0)(ADDRESS = (PROTOCOL = TCP)(HOST = server.name.removed)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = serviceName)
)
)
FIRE.FIREPOPPY.COM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = server)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = fire)
)
)
####################################
# Date..........: Tue Aug 28 20:46:43 PDT 2001
####################################
INST1_HTTP.FIREPOPPY.COM =
(DESCRIPTION =

)
(CONNECT_DATA =

(SERVICE_NAME = fire)
(PRESENTATION = http://Server/admin)
)
)
TRACE_LEVEL_LISTENER = ADMIN
TRACE_FILE_LISTENER = listener
TRACE_DIRECTORY_LISTENER =E:OracleOra81networktrace

If the port is open then you can remove the TIMEOUT parameter. This wouldn't be the problem. A TAR is Oracle's method of correcting problems with clients with a current service contract. Post your sqlnet.ora file. First try "tnsping FIRE.FIREPOPPY.COM". Does that work? Did anything change with your tnsnames, listener, or sqlnet ora files since you were able to connect the last time?

I was able to tnsping the local DB fire.firepoppy.com yesterday and got a response back from it. I have since reinstalled the Net8 clinet stuff from Oracle in order to confirm that nothing has happened to the client libraries. I re-established the tnsnames.ora file and confirmed thier addresses.
Thanks again for your help on this one. It is really driving me batty.
Below is the new sqlnet.ora file:
# SQLNET.ORA Network Configuration File: E:OracleOra81NETWORKADMINsqlnet.ora
# Generated by Oracle configuration tools.
NAMES.DEFAULT_DOMAIN = firepoppy.com
SQLNET.AUTHENTICATION_SERVICES= (NTS)
SQLNET.CRYPTO_SEED = 4fhfguweotcadsfdsafjkdsfqp5f201p45mxskdlfdas
NAMES.PREFERRED_SERVERS = server.firepoppy.com
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
TRACE_LEVEL_CLIENT = 16
TNSPING.TRACE_LEVEL=user
TRACE_LEVEL_CLIENT=USER
TRACE_FILE_CLIENT=CLIENT
TRACE_DIRECTORY_CLIENT =E:OracleOra81networktrace

If you could tnsping fire.firepoppy.com then you should be able to get to it with sqlplus. fire.firepoppy.com is the host string. Does that work?

It isnt the local DB that I am having trouble with it is the remote connection to shop1.firepoppy.com. Althought now that I am running around with my head cut off it looks I may have mucked up all kinds of things. I am getting a TNS-12154 error for all DBs now.
But when I add a new service through the net8 client and specify the remote DB to connect to I still get a timeout error which was the original problem. I think I am totally lost now.
What is the control file the I need to edit to stop the TNS 12154 error (could not resolve service name)?

Hi Sean,
Looking at the problem you faced some time back with oracle client connectivity to the database server behind a firewall, I am having the same problem and the trace file generated after the tnsping shows the same problem with the socket. If you have find a solution for the problem and let me know I will be grateful to you.
Thanks
Samir Saha

We experienced that a bluetooth installation on the machine made socket opening fail on local TCP (tcp connections to database from sqlplus client on same machine) connections. Disabling bluetooth made things work. I guess that we could have configured the bluetooth differently and enabling concurrent use, but theisse has not been explored.
