Networking And Gateways :: Getting Error TNS / Operation Timed Out
Jun 26, 2012
One of our production database we are getting error "TNS:operation timed out" from unknown port in alert logfile. Need to check why TNS error is occurring to these unknown port as our listener is running on default 1521 port. Also to inform that host=192.191.118.24 itself is the same database hosting server IP.
TNS-12535: TNS:operation timed out

I have two related questions:
Scenario 1:
1. I have two remote Windows machines with database on each. One is Win 2003 Server (machine A) and another one is Win XP (machine B)
2. I can ping from A to B.
3. I can ping from B to A.
4. I can tnsping from A to B.
5. I CAN'T tnsping from B to A.
6. Windows Firewall on both machines are off.
What could be possible reason for point# 5?
Scenario 2:Now, the second part:
1. I had an unwanted entry in tnsnames.ora on B which I removed.
2. Then I restarted the listener on B. Actually, I wanted to restart the one on A to check if that resolves issue mentioned in point# 5 above.
3. I tried tnsping from A to B but suprisingly it is also giving "operation timed out" error now. So now tnsping not working from either sides.
I didn't make any changes in listener.ora on B, just stopped it and started again. Only change made was removing unwanted entry in tnsnames.ora on B.
Why does that affected database connectivity from A to B which was working fine previously?
NOTE: The two machines are connected through VPN using LogMeIn Hamachi. Hamachi assigns it's own IP address to each machine. Machine A is Windows Server 2003 and B is Windows XP.

I have a windows XP server with Oracle 9i on it, when i tried to connect this server from another win XP machine after creating a service. I m getting an error
TNS-12535 TNS:operation timed out
But as i know this error is related to CONNECT_TIMEOUT and it is now obsolete in 9i( am i correct ). I tried it doing from 2 machines but got the same error from everywhere so it means that the problem is with the server.my files are :
Listener.ora
# LISTENER.ORA Network Configuration File: D:oracleora92NETWORKADMINlistener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Tarun)(PORT = 1521))
)

I am trying to connect to a server from a client on another network. I am able to connect just fine if I am on that server, but when I try to connect from a client in my office to the amazon server, I get a timeout message as follows.
ora-12535: TNS:operation timed out.
here is my entry in my local tnsnames.ora file. I believe that the network is wide open between my two computers. o firewalls on the computers and the settings on my cisco allow this to go through. I see the client connect in log files on the server, but it always gets a timeout after 20 seconds.
I have tried to add these parameters to the sqlnet.ora file.
SQLNET.SEND_TIMEOUT= 120
SQLNET.RECV_TIMEOUT= 120
SQLNET.EXPIRE_TIME = 120
SQLNET.INBOUND_CONNECT_TIMEOUT = 120
RDCTEST2.rdcamazon.com =
[code].....
How would I go about debugging this? I replaced the ip with x's since this is a public post.
client = windows xp
server = windows 2003 server
I am able to connect to a local database server from my client without a problem.

My database link to the remote database used to work fine until the company VPN was updated for some security reasons. Now When I try to connect using the DBlink now, error comes up:
TNS 12541 no listener.
Checked the actual listener on the remote database(destination) and it is up and running fine. I am able to ping their machine.
ping <remote host> -works fine
tnsping<remte host> -fails
it comes back with error
TNS 12541: no listener
Nothing has been changed on both databases. The destination database can connect to our database without any issues(they can tnsping and use the dblinks to our database).
LISTENER ENTRY:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
[Code] ......
None of the above should be the cause because there was no change been made on any of these.

I installed local database on my laptop that pc is inside a domain when i remove the network cable and connect using the sid defined in the tnsnames sys/sys@ora10g as sysdba it gives me that errors
ORA-12560: TNS:protocol adapter error
to resolve this problem i should connect like that sys/sys as sysdba without the sid but i don't want to connect in this way because i have work must be done from home on that local database so i don't want to connect with network sys/sys@ora10g as sysdba and without network sys/sys as sysdba.
i want to be always connect sys/sys@ora10g as sysdba.

I have overwritten tnsnames.ora file with newone. In new tnsnames.ora file I have added new host string, remaining all unchanged.
after that, when trying to connect using sqlplus(from windows machine, sqlplusw.exe), working fine. But when trying to connect through putty getting error.
ORA-12154: TNS:could not resolve service name
for the same reason my scheduled cron tab can not run export backup. cron tab error is
EXP-00056: ORACLE error 12154 encountered
ORA-12154: TNS:could not resolve service name
EXP-00000: Export terminated unsuccessfully
I am suspecting problem may be due to file accessing permission related issue. But cant solve it. Current tnsnames.ora files permission is

I have one production server with oracle 11g R2 DB. I have to change Server Hardware and thats why I have to install oracle 11g R2 DB on New hardware and test it. I had installed DB with software only option and copied the cold backup of production server. The hostname and ip address of both the servers are different. I had change the "db_domain" parameter into init.ora with the hostname.Now my question is that can the same db runs on the same network with different hosts. Change of "db_domain" parameter into the init.ora is enough or i have to follow some other procedure.

I installed Oracle Express on my Windows 2003 Enterprise server. And right off the bat I cannot connect to it via command line. I have googled and read many sites, but am still getting the same error, no matter what I do. I am newbie again (was a DBA in 1990...when I used to have the same error and fix it in seconds...not sure why this problem still lingers in Oracle) so most likely I am overlooking something. Below are my tnsnames.ora and liserner.ora files

My client get the error Ora-12514 when he tries to connect to the db.Well;
1) we restart the services: "OracleServiceOrcl" and listener but nothing changes
2) We restart the server and nothing changes
3) We checked the dump and he was done on March,26th. No db export yesterday. Is there any link with the clock change of this week-end (location of the server: France)?
4) The lsnrctl services listener command run successfully but it doesn't mention the instance ORCL.
