TNS-12535 error using BO 5.1

We have recently moved an Oracle database from Windows NT to Windows 2000. One particular user keeps on getting ORA-12535: TNS: operation timed out.
What could be causing this?
The user can run SQL*Plus and connect to the database without any problems.
Please can someone advise?
thank you,
MK

TNS-12535 Error on Windows with Norton Worm Protection

Hope this mail can help another users installing oracle 10G with Windows and Norton Antivirus with Internet Worm protection enabled; having the error TNS-12535
I try to install Oracle 10G v1 and v2 on Windows XP SP2 with Internet Worm Protection enabled (for several hours I didn´t realize that the problem was that). Have problems with listener and my IP address or host; it resolved in first instance changing the configuration to localhost or 127.0.0.1; but I can't receive client connections. And after a few traces and less hair; discover that Norton Internet Worm Protection locks Oracle 1521 port; just reconfigured it and works fine.
If you look in Norton Log Viewer you will see something like this
Details: No logged in account. The present default action is to "block" communications.
Inbound TCP connection.
Local address,service is (HOST_NAME(IP_ADDRESS),1521).
Remote address,service is (HOST_NAME(IP_ADDRESS),1219).
Process name is "X:\oracle\product\10.1.0\Db_1\BIN\TNSLSNR.exe".

Tns-12535 error: timeout on windows 2000

Issue--
Installed Oracle 8.1.5 on windows 2000. A database was created successifully and funtions. However, I got TNS-12535 'listener time out'when trying to connect the server from client. Reset the timeout parameter to 0 in listener.ora but it didn't help. It's also found that there is no sqlnet.ora within admin folder.
Question--
1. Why was sqlnet.ora not created? No need?
2. Shoud I copy a sqlnet.ora file into admin directory?
3. How to sovle tiemout problem? any additional setting?
Thanks

I have checked the Toshiba driver page and it seems that the common modules for Tecra S1 are not available.
Anyway, the Tcmsvr.dll file could be also a part of Toshiba console. Its very difficult to detect it.
The Toshiba console is available on the driver page.
It's worth a try.

Oracle TNS 12535 error after moving repository DB from Win NT to Win 2K

Business Objects 5.1
We have recently moved an Oracle database from Windows NT to Windows 2000. One particular user keeps on getting ORA-12535: TNS: operation timed out.
What could be causing this?
The user can run SQL*Plus and connect to the database without any problems.
The user gets this error when running BO itself. When running our Application or any other Oracle tool or utility (TOAD, SQL*Plus), etc, then all works fine.
From my own PC I can use the 'problem' users BO login to connect to the repository.
So the nature of the problem suggests a network or configuration issue of some kind. We have limited BO expertise at this site.
Please can someone advise?

MK

Hi Mo,
If the previous solution provided doesnu2019t works then check the following things:
1. Check the ORACLE_HOME value in the Registry and ensure that your PC has only one "ociw32.dll" file.
2. Confirm that the PATH environment variable definition's first Oracle /bin folder path points to the middleware
installation you intend Supervisor to use.
3. Add the repository database server's IP address to the local HOSTS file.
4. Confirm the repository database's entry in the Oracle TNSNames.ora file.

Hi,
Nothing to investigate at the application side, there is everything to investigate at the network side.
Check the below points.
- is there any firewall in play
- is there any Network Address Translation into play
- have the correct ports been opened in the firewall
- is Oracle using random return ports (by default Oracle always uses 2 tcp/ip ports, the first one fixed, and configured in tnsnames.ora, the actual communication takes place on a radom port. If that is a problem at your site you need to fix that)
- You need to run netstat -r to identify which ports are actually used.

TNS-12535 TNS:operation timed out - Win 7 - WAN

Hi!
Database Version: Oracle 11.2.0.2
Server OS: Linux 64bit
Database server "A" at different location (connecting through a 10 MBPS link - latency 15 ms).
I can ping to server.
When i connect to server "A" from client on Windows 7 I got TNS-12535 error (All Win 7 clients).
Firewall on client is down.
When i connect to server"A" from client on Win XP or Win 2003 server is OK.
Both TNSNAMES.ora and SQLNET.ora are the same on each client.
tnsnames.ora
db11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.0.10)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = db11)
From all clients I can connect to local database server "B" without problem.
Laptop with Win 7 carried to location "A" can connect to server "A".
I've tried Oracle clients from 10.2 to 11.2 and in each case 'tnsping db11' give TNS-12535 error.

You are NOT going to like this answer, but all is symptomatic of Firewall between client & server.

Hi everyone,
I am starting to play with Oracle DB recnetly..

I can connect Oracle DB by http://localhost:8080/apex and sqlpus.
and check - telnet ellen.test.net 1521, it is working.
I have no idea why my TNS connection got timeout issue.
Did someone encounter the same issue before?

Is it related?I can not say it is related with 100% certainty.
You can conclude I had a REALLY lucky guess or there is high correlation between VM & having TNS-12535 error.
It is your system & you are free to (ab)use it any way you choose to do so.
We both know SQL*Net can & does work as advertised, but requires a properly configured OS & Network underneath it.

hi,
Please check the connectivity from server to client.
And also check whether the tnsnames.ora file has the TNS entry of the DB server which you are trying to connect.
Then TNSPING the server with tns name.
If this also doesnt work try commenting all lines in sqlnet.ora file on server.
Check the listener status also on the server.

TNS-12535: TNS:operation timed out Question

I get the following error when I try to connect using oracle 9i personal client.
TNS-12535: TNS:operation timed out
The thing is the connection worked 2 days ago and then all of the sudden I get this error.
I've tried changing the CONNECT_TIMEOUT to 0, but that hasnt work.
Anyone have a solution?
thanks, bryan

sounds like a problem reaching the database over the network (or remotely, however that may be). Be sure you have access to the directory where your tnsnames file is located, if you have TNS_ADMIN set in the regisrty, make sure it is pointing to a directory you have access to, etc. I had this error the other day and it turned out it was just failure to connect to the tnsnames file directory on our network.

Dear Friends,
I am using Oracle Apps R12.1.1 and the DB Version is 11.1.0.7
I am getting the following error in my DB Alert Log:

I would like to know this error is happening for the client 172.16.0.9?
Is it related to any server issue? Is it any critical issue?
Please let me know.

Is this error frequently occuring?
Sometimes due to network disconnection these kind of errors may happen.

Thank you.

Hi Bruce,
The scenario you just provided is what you don't want. You want Bruce-Desktop to have a static address. The easiest way to have this setup properly is to look at the IP address that is assigned by the DHCP server and assign that address statically to the interface.
The way you have it now, I cannot tell which IP address Oracle will be using because that will depend on the binding order. You can control that by going to "My network places" -> "Properties" - > "Advanced" -> "Adapters and Bindings"/"Provider Order". It complicates matters though to do it that way.
Since I cannot see exactly in what state your installation is, I would suggest you start over, this time with the network setup as needed. I can help you with the setup if you are willing to go thru the installation again. Trying to guess everything that should be modified in your current installation will be too error prone.
John.
For a new, clean installation, these are the basic steps:
1. Set the computer name appropriately, something like "orahost" is a reasonable choice.
2. Set the primary DNS suffix for the computer to something like "bruce.local"
3. Set the IP address of your computer to be static (you won't even need a loopback adapter)
4. Enter the appropriate information in your hosts file, given the values I mentioned above, it should look something like:
127.0.0.1 localhost
192.168.247.120 orahost.bruce.localchange the 192.168.247.120 to whatever IP address you statically assigned in step 3
When you create the database and it wants the database name, enter <databasename>.bruce.local
Another recommendation, in that same screen, it will want the SID, I use <databasename>sid. This makes it clearer later when Oracle expects an SID instead of a connect identifier or a database name. (though most people have the sid set the same as the database name - for learning purposes, I believe you are better off with different values, in order to tell, when it wants one instead of the other - otherwise, it's hard to visualize)
This way you are mimicking an installation that is closer to a real production environment.
If you want to use DHCP, still do step 3 but reserve the IP address you assigned statically in the DHCP server, that way the static IP will match what would have been assigned by the DHCP server.
HTH,
John.

ORA-12170 and TNS-12535

Hi everyone
My servers are in a separate location and we are accessing our databases from my office.
The developers say that they couldn't access one particular db from their machine.
The errors they receive when they try to connect using some tool is:
TNS-12535 TNS:operation timed outWhen I request them to TNSPing or when they access from Sql Plus(instant client), this is the error they receive:
ORA-12170: TNS:Connect timeout occurredOne of the developers are using Oracle XE and he too faces the same scenario.
So, where should I trace this problem from.
We all could ping to the machine where the Oracle resides.
Please advice.
Thanks in advance.

Tns_Admin & Tns 12535/37

Hi,
Db : 11.2.0.3.0
OS : Red Hat Enterprise Linux Server release 5.7 (Tikanga)
We use ASM for stroage.We often get TNS 12535/37 in alert log.
Listener file is located at /u01/app/11.2.0.2/grid/network/admin/listener.ora.
But TNS_admin is differ when execute the below one as a gird user.
srvctl getenv database -d i56_0 -t "TNS_ADMIN"
I56_0:
TNS_ADMIN=/u01/app/oracle/network/admin
Should i change tns_admin in grid user?
If it's,is it solve the probelm TNS 12535/37?
Any suggestions,
Br,
Raj

12535, 00000, "TNS:operation timed out"
// *Cause: The requested operation could not be completed within the time out
// period.
// *Action: Look at the documentation on the secondary errors for possible
// remedy. See SQLNET.LOG to find secondary error if not provided explicitly.
// Turn on tracing to gather more information.
[oracle@localhost ~]$ oerr ora 12537
12537, 00000, "TNS:connection closed"
// *Cause: "End of file" condition has been reached; partner has disconnected.
// *Action: None needed; this is an information message.
It appears to me networking problem exists.
Oracle is the victim; not the culprit.
Root cause & fix are external to Oracle; since Oracle depends upon OS for any & all network pack exchange
