TNS-12535 TNS Operation Timed Out....Pls HELP!!!

Hi All
I have created a oracle 9i database on my local machine and when I try to connect to it from same machine via sqlplus or OEM, I am getting this error message:
TNS-12535: TNS Operation Timed Out.
I have tried to create a new listener but still I cannot connect to database.
Does anyone has any clue what's happening.
Thank you
Amit

Hi,
You could try something, like :
If your System is a Windows system, check if the listener service is active.
Then, from DOS window :
- LSNRCTL stat, to see the status of the listener
- TNSPING <your tnsnames alias>, if you have one.
For local connections :
- set ORACLE_SID = <your SID> as environment variable, then connect as user/password without connection string.
You can also try to stop and start the listener (from dos) :
- LSNRCTL stop
- LSNRCTL start

TNS - 12535 - Connection Operation Time Out

i m getting this error again and again. to overcome this problem, i have searched
CONNECT_TIMEOUT parameter to asign '0' zero vaue, to get higher higher time in listner.ora, but there is no any such parameter in it.(as suggested my teacher) hence i reconfigured my listner, the said prob get solved. but the next day i found the same error. what should be do? is there any solution?
thanx in advance

from the client (using dos command prompt)
tnsping instance_name
Also check your tns_names file on the client and make certain you are pointing at the correct machine. Check the machine and make certain the listener is listening for the correct alias.
Something is not working correctly.
Are the other clients having the same problems or are they able to connect?

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.

I know its a timeout error, but I would like to know what is timing out and why. All I want is the database its self to run to allow me to connect to it via SQLPlus and JDBC.
Is there any information on what the following services do and which ones I need to have running to use the database.

Either reconfigure CONNECT_TIMEOUT to be 0, which means wait indefinitely, or reconfigure CONNECT_TIMEOUT to be some higher value. Or, if the timeout is unacceptably long, turn on tracing for further information.

the most frequent cause for TIMEOUT is a FireWall on or between client & server.
when was last time this worked without error?
what changed since then?

Hello,
I am trying my first JDBC connection using a code sample called SingleConnection.

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-12535: TNS:operation timed out on other pc

After installing the XE edition on a server, I can connect fine on the server itsself. But when I try to connect from a client machine, I get ORA-12535: TNS:operation timed out.
My tnsnames on the client holds this string for the XE db:
MyDB.10gXE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = MYSERVER)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
any ideas???

Rather than
MyDB.10gXE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = MYSERVER)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
why not go with the bulk standard tnsnames entry as follows:-
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = MYSERVER)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
I don't think the qualified MyDB.10gXE name is adding any value and may well confuse things.
Although setting it for my environment does work

ORA-12535: TNS:operation timed out on a win2000 Oracle instance

Hi,
i have a Oracle 8.1.5 instance on a WIN2000 PC.
I can connect me to this database with sqlplus
as long i stay on the PC (means i started the sqlplus
on the same machine).
When i try to connect from an other (unix-)system
i get after a while (ca. 90 sec.) the error:
ORA-12535: TNS:operation timed out
tnsping works fine (answer comes back in one second)
There are no firewalls or other "strange" things between
the database and the failing client (on an other PC,
also win2000, Oracle 8.1.5 everything works fine).
Below you see the log with debug of the listener.
I have also a trace on level SUPPORT but this is more
than 1000 lines for just 1 or 2 TNSPINGs and one SQLPLUS
connect. Due to this volume i decided not to attach it to
this initial mail.
Does any one have some advice or experiences ?
Please advice.
Best regards,
[email protected]

Rather than
MyDB.10gXE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = MYSERVER)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
why not go with the bulk standard tnsnames entry as follows:-
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = MYSERVER)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
I don't think the qualified MyDB.10gXE name is adding any value and may well confuse things.
Although setting it for my environment does work

OK - when I use your entry pasted directly from the above, with my server name, I get the following problem:-

TNS-12560: TNS:protocol adapter error, ORA-12535: TNS:operation timed out

I installed Oracle 9i (9.2.0.1.0) on a Windows XP machine (the machine is in a domain). There were no errors during the instalation, but I have problems connecting from the same machine using the sid. Here are some examples from a command promt:

Thx.

Yes, the XP firewall is running. During the Oracle instalation it poped up twice, but I selected 'Unblock'. I can't turn it off because it is running using the domain settings, but I can add exceptions (programs or ports). Port 1521, tnsping or sqlplus are not blocked and there is an option 'Display a notification when Windows Firewall blocks a program' witch is checked.

TNS-12535 TNS Operation Timed Out....Pls HELP!!!
