Urgent - no listener: no TNSLSNR.exe
Hello,
I had a probem with ODBC in that I couldn't do anything with it, nothing at all, so I had to reinstall the net8 tools for Oracle8i on a W2K server platform. While ODBC is now up and running the listener has now disappeared: the file TNSLSNR.exe is missing.
Any advice would very appreciated...
Hi,
I don't know too much about this to be honest but I have some suggestions so I'll throw my two cents worth in. A few things come to mind, first I'd check the client, the issue looks like its there, second check the local security setup and third if your using Active Directory there are special directory issues.
Hope this helps

TNSLSNR.EXE - Application Error
We are running an Oracle 9i r2 DB on Windows 2000 (Active Directory). We recently encountered a problem when starting the external procedure listener service using a domain ID.

An unhandled win32 exception occured in TNSLSNR.EXE[1624]
Hi, I don't know if anyone can help me with this, but I always get the win32 exception error everytime I start the tnslistener and open the enterprise management console at the same time; well, the error will pop up in about 10~15 secs, and tnslistener crashes/stops, only after I start using the enterprise management console.
The JIT debugger shows this:

TNSLSNR.EXE crashes - 9i2 on XP
I installed Oracle 9i2 Personal Database from the file downloads.
Immediately after connecting to the database using SQL PLUS, TNSLSNR.exe unceremoniously crashes. No errors appear to be logged to the listener log. There is an error showing up in the event log:
Faulting application TNSLSNR.EXE, version 0.0.0.0, faulting module orantcp9.dll, version 0.0.0.0, fault address 0x00005732.
The listener also crashed during installation during the database creation. Another symptom of this installation is that oracle.exe will sometimes start consuming all available CPU forcing me to stop the service.
I've seen other threads here similar to this but have yet to find a resolution. Any help would be appreciated.
GaryI am not sure whether you fixed this error and how
you did. I had the same problem. But, when I searched
this forum, I got 3 threads and none of them led me
to the right solution.
Here is how I fixed it. First installed and ran
Ad-Aware and Spy-bot to detect any unknown spywares
and removed it. Then ran this file LSPfix.exe
(http://www.cexx.org/lspfix.htm) - which in turn
repaired my winsock setting.
Now, no more TNSLSNR.EXE crashes.
HTH,
AllwynHi Allwyns,
Just like to say a very big THANK YOU, I was having exactly the same issue and it was driving me mad. Followed your suggestion and it worked like, didn't even had to re-start my machine.
Cheers,

9i TNSLSNR.exe Application Error on 2000 Prof.
When I connect to a local database, I seem to be getting TNSLSNR fatal error in which the listener stops working. The following error is returned:
TNSLSNR.exe - Application Error
The instruction at "0x012cf8d8" referenced memory at "0x02604b1c". The memory could not be "written"
Click OK to terminate the program. Click on Cancel to debug the program.
Clicking on either button does nothing.
8.1.5 and 8.1.7 worked fine on this same machine. This is a fresh installation. It has been reinstalled once. Only using SQL Plus and Oracle tools when the error occurs. I've also attempted to use the loopback IP of 127.0.0.1. Same error. Your assistance is greatly appreciated.I determined that the problem was related to VPN software installed on the same machine. The software was Aventail Connect. Oracle seems to be working fine.

URGENT : EVENT Listener Problem
Hi All,
Thanks for your time. I am facing a Small issue with Event
dispatcher and Add Event listener. Well i will explain the problem.
I am having one MovieClip named BUTTON_SET and i gave
"ButtonSet.as" as linkage Class.
Inside that BUTTON_SET i am having some Buttons and they are
also having "UIButton.as" as linkage class
UIButton Dispatching press and release events, But unable to
capture it using ButtonSet Class. Here with i have attached the
Code and i gave the Source URL Too.
upto my Knowledge : UIButton class is not initiated When the
ButtonSet is ready to addListener.
Please Help me to fix this.
if i don't find a solution i need to change all my class
structures.
CLICK HERE FOR SOURCE
CODEAccording to your Code, When you are calling the InitHandler
Functionction the Buttons may/may not be Initiated. So use the
Enterframe to check whether its loaded or not.
Write down this in the ButtonSet to replace the init Handler
Call.
this.onEnterFrame = Delegate.create(this, initHandler);
inside the initHandler remove the function This will help you
if you are not using any Enterframe for any other manipulation)
delete this.onEnterFrame; -
Urgent : regarding listener port functionality in Websphere 5.0
Hi all,
In my production I have two different Listener port (LP1 from JVM1) and (LP2 from JVM2) pointing to the same queue in the queue manager. Let say that a message gets dropped in the queue will there be any conflict for the message since two differnt thread(LP1 and Lp2) are looking at the same queue. Is there any best pratice that only one listener thread should be looking at one queue. Have anyone used the same architecture to run in the production environment and has issues with it.
Thanks
ManojThe code looks OK. I can only think of 2 suggestions:
1) install fixpack 8 or better for the 5.0 runtime
2) make user you have the TCP/IP moniter installed between the WS clinet and server (not between the browser and client). You should see the SOAP packet in the data in the request window. There is detailed help under "Using the TCP/IP Monitor to test Web services".

All instances names on one NETWORK
How i see all oracle instances which are present on my network domain.
is there any command for CMD.
ThanksDon't expect to find a single command to track your network, and you should specify if you are talking about unix or windows. You should have privileges to get connected to the target host and issue a netstat command to find if there is a listener currently working there:
netstat -b -a
TCP alpha:1521 alpha.us.oracle.com:0 LISTENING 3644 [TNSLSNR.exe]
This will let you know where the listener is working and in case you have more than one listener, any additional ports. You will have to find each Oracle Home and execute the lsnrctl services or lsnrctl status command. This will show you the currently working instances, but in case instances are down the only way to find out will be to directly go to each Oracle Home and find out if there are the configuration files, such as init* or spfile* and find out if they are still active.

Hi I have a rather urgent issue - I thought this would be simple but it is not working. I feel I am close:
I have an instance name TIRAT04, but I am rebuilding it and must rename the new one TIRAT04A. I want all my applications to still be able to connect using the old SID, but am not having any luck. All client are jdbc thin, using the Oracle 10.2 driver.
I have gotten as far as being able to tnsping the new connection locally, but my jdbc client still give me the error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
Here is my listener.ora and tnsnames on the DB server:
listener.ora:

TIRAT06A =

(DESCRIPTION =
(ADDRESS_LIST =

(CONNECT_DATA =

(PRESENTATION = RO)
=================
Anyone know what I am missing? Is this possible with the thin client?
appreciated!
TrevorMore info - I can connect with the EM console using the alias, but unfortunately this is an OCI connection, not JDBC thin. The problem seems to lie in the request for SID (jdbc) vs SERVICE_NAME (OCI)
06-MAY-2006 00:51:49 * (CONNECT_DATA=(SID=TIRAT06A)(CID=(PROGRAM=)(HOST=__jdbc__)(USER=))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.5.150.55)(PORT=2120 )) * establish * TIRAT06A * 12505
TNS-12505: TNS:listener does not currently know of SID given in connect descriptor
06-MAY-2006 01:02:38 * (CONNECT_DATA=(SERVICE_NAME=TIRAT06A)(CID=(PROGRAM=C:\oracle\product\10.2.0\client_1\jdk\jre\bin\java.exe)(HOST=TMARSHALL )(USER=tmarshall))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.5.150.55)(PORT=2185)) * establish * TIRAT06A * 0
How can I resolve SID to SERVICE_NAME, without changing the jdbc datasource in my applications? I know the SID is actually burned into the DB.
I followed this thread Listener alias question.
but it didn't help. Same problem, but not JDBC.
