TNS-12518 error on windows 64bit -

hi all
we are getting the above error when connecting using SQL plus
we have 10 databases on the server
is this erorr due to resources onthe windows box
thanx

is this erorr due to resources on the windows boxThat's one possible cause.
How many resources are you using? How many do you want, and how many do you need?
Add up all the SGA+PGA for all ten instances, if its near the total memory available on the box ... move a couple instances elsewhere.
You've got to have a couple GB free for the OS.

TNS-12518 error while trying to fetch data from SQL Server

Hi everyone,
I'm trying to establish connectivity from Oracle 10.2 server to a SQL Server 2005. These are the server details
DOVER - This is where I installed Oracle Gateway for SQL Server. There's already an Oracle home in this server and I have used the existing listener for the incoming connections
LUNDY - This is where my actual Oracle server resides
HEBRIDES - This is where SQL Server 2005 instance resides, the database name is TRACKIT90
I've set everything as explained in Oracle documentation http://download.oracle.com/docs/cd/B19306_01/gateways.102/b14270/ch2.htm#i1005694 but in the end I'm getting an TNS-12518: TNS:listener could not hand off client connection when I run a test query and this is what it says in the listener.log of DOVER
01-MAR-2010 15:33:19 * (CONNECT_DATA=(SERVICE_NAME=tg4msql)(HS=OK)(CID=(PROGRAM=w:\oracle\product\10.2.0\db_1\bin\ORACLE.EXE)(HOST=LUNDY)(USER=))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.0.0.58)(PORT=3887)) * establish * tg4msql * 12518
TNS-12518: TNS:listener could not hand off client connection
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 2: No such file or directory
My initialization parameter under \\ORACLE_HOME\tg4msql\admin of gateway installation in DOVER is as below:
HS_FDS_CONNECT_INFO=hebrides.TRACKIT90
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
The listener.ora of the active listener in DOVER has the following lines, by the way this listener does not reside on the same ORACLE_HOME as the gateway's ORACLE_HOME but it is the current active listener in the server. The listener has also been stopped and started:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dover)(PORT = 1521))
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
SID_LIST_LISTENER =
(SID_DESC =
(SID_NAME = tg4msql)
(ORACLE_HOME = E:\oracle\product\10.2.0\tg_1)
(PROGRAM = tg4msql)
The following entry has been added to the tnsnames.ora in LUNDY server where my actual Oracle database resides.
TRACKIT_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = DOVER)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = tg4msql)
(HS = OK)
And finally a database link is created by using the below DDL statement:
CREATE DATABASE LINK "DLINK" CONNECT TO "username" IDENTIFIED BY "password" USING 'TRACKIT_DATA';
When I do a select statement on one of the tables of TRACKIT database by using the following query I got the TNS-12518 error with above details
select * from announcement@dlink;
I would appreciate any help and also please let me know if I missed out any details.
Thanks.

This is the output comes with the "lsnrctl service listener" command on DOVER server

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-12518: listener could not hand off client connection

We've recently upgraded to Oracle 9.2 (on Solaris 9) and are having intermittent problems. After being up several hours we approach around 250-300 active connections to the database. Then intermintantly all clients receive TNS-12518 errors or Error 0 or even other errors--all basically saying they can't connect. The problem sometimes comes and goes within seconds, other times sticks around for about 30 minutes. During this period if someone has an active connection they are absolutely fine and unaware of the problems. It's only new connections that get locked up.
We've got three dispatchers running a max. of 500 connections each and we've validated we can get up to 500 connections without a problem using some simple scripts. We haven't seen any log entries or alerts other than the actual TNS error message.
We're prepared today to turn on intensive logging if it happens again to see if that gives us a clue. I've seen only a very few messages on the Internet about this error but unfortunately no suggestions that have proven helpful.
We're open to any and all suggestions as this has been crippling us for about a week now.
Thanks in advance!

We had a similar problem on one of our servers (not Sun). After much investigation, we found that it was a result of one of the UNIX level parameters. I do not recall the exact name, but it set a limit on the number of active processes that a particular O/S user could have active at the same time.
Since all processes connecting to the database use the oracle userid, we solved the problem by upping the limit.
One of our symptoms when we had the problem was that the user oracle was unable to even log on to the server.

[HELP] 10g error TNS-12518: TNS:listener could not hand off client connecti

Hi all,
TNS-12518: TNS:listener could not hand off client connection
(when I do a sqlplus, it hangs for one two minutes, then the error above shows)
My oracle 10g is installed in a windows system. this error only happens when the database is heavily used for some time. After I restarted the Listoner, the connection is ok again. Does anyone has a solution for this? Thanks a lot.
Jason

Monitor your page file usage on Windows system (I assume its a 32 bit machine). When Windows starts to swap Oracle SGA into page file., you encounter TNS errors. Strange but we have observed this.
If you can allocate more free physical memory on the server (by removing unwanted applications from the memory), then you can reduce these errors.
Permanent solution would be to add more physical RAM (with 4GT on 32 bit) or switch to 64 bit architecture.

Typo corrected and added following.
You can set DIRECT_HANDOFF_TTC_LISTENER=OFF in listener.ora and restar the database as temporary solution. Check metalink Doc ID: 233747.1

TNS Timeout Error with both 32bit and 64bit drivers installed

I have a server running WIndows 2008 64bit and SQL Server 2012 64bit. I have both the 32bit and 64bit Oracle ODBC drivers installed. 32bit is for SSIS and SSRS uses 64bit. I have an ODBC connection setup for both the 32bit and 64bit. I have the datasources setup for the 64bit and when I test it it works. When I go to run a query I get TNS timeout errors. Any ideas?

Thank you very much, Curt!
It's right: When the 64bit version is running, then the PSDs will be opened by this.
But the configuration under "Bridge Edit/preferences/file type assoiciatons" has the same result as under the "Windows/Systemcontrol/Standardprograms": Never they show the name "Adobe Photoshop.exe (64bit)" - only "Adobe Photoshop.exe" In both cases (Bridge and systemcontrol) I have the possibility to choose the "right" Photoshop.exe by going to the right file (32bit OR 64bit), but the name of the .exe is ever the same: Only "Adobe Photoshop.exe". There is no difference.
And so even if the 64bit version is preferred (in Bridge), the PSD-files will be opened in the 32bit-version, when no one of both versions is running.
But - so or so - you have given me a way to solve my basic-problem!
And when I find the time for experiments, I will show what happens, when I rename the 64bit-exe to "Adobe Photoshop64.exe" to get two different filenames for Photoshop in the Windows-System. (I'm not shure if this will function: When in the Photoshop-System are intrinsic lnks/references to "Photoshop.exe", then I will have no success! Therefore I have to make a HDD-Clone with the whole Windows-System, all Apps and my Working-data before I try to rename. Perhaps there is "no way back to the activation" after renaming the .exe ...
Thank you and kind regards,

TNS-12560 error when running as Windows Service

Hello,
I created a VB.NET application that connects to a Oracle database using DbProviderFactory and ODP.NET for .Net Framework 2.0. This application runs on XP, I need it to run as Windows Service, but every time it try to connect to the database throw the Oracle exception TNS-12560: TNS:protocol adapter error, the weird thing is the same application running as a Console Application it works (Same code, same connection string, same query). It was using ODP.NET 10 I updated the provider to 11 still got the same error. The service is running user Local System account, and it has the same problem running under other adm account.
Following is error in the sqlnet.log (PS: The file was under the system32 folder, probably because was running as a service):

I don't know :^(
There could be many reasons: differences in the environment, missing permissions, virus scanners, you name it.
Is it running under the same user as on the console?
I suspect that the error code will give a hint where the problem is, but I could not find any documentation what this code means.
You could try to run an Orace Net trace - maybe you get an idea if you see where in the connection process the problem occurs.

Windows 64Bit Itunes Error : "THERE IS A PROBLEM WITH THE WINDOWS INSTALLER PACKAGE. A PROGRAM REQUIRED FOR THIS INSTALL TO COMPLETE COULD NOT BE RUN CONTACT YOUR SUPPORT PERSONNEL OR PACKAGE VENDOR."

I have a brand new HP laptop windows 64bit that is having issues installing Itunes 10.6.3. Whenever attempting to install, I get the error message : "THERE IS A PROBLEM WITH THE WINDOWS INSTALLER PACKAGE. A PROGRAM REQUIRED FOR THIS INSTALL TO COMPLETE COULD NOT BE RUN CONTACT YOUR SUPPORT PERSONNEL OR PACKAGE VENDOR." I thought this was an issue with the new version, and attempted to retrieve/install older versions of Itunes and same issue occurs. I have tried other forums and resolution tips from : https://discussions.apple.com/docs/DOC-3551 and nothing still. It appears that apple installs bonjour and nothing else. I have tried extracting the itunes package and installing the executables seperately, but everytime the error stil arises. I cannot repair the apple software update as it cannot install from the error mentioned above. Looking through the logs, it shows error : 1721, problem with windows installer package.Does anyone have any suggestions on what to try?

There are so many different error and problems peopl are having.

Hopefully they fix it soon. Ive used a few GB redownloading and Im going crazy

TNS 12549 error on installing Oracle 10g on Windows XP Home?

Hi,
I installed Oracle 10g on Windows XP Home by clicking on Disk1\install\setup (NOT Disk1\setup as instructed since that did not work). Everything seemed to go fine except towards the end of the install I got a whole bunch of errors saying that "operating system resource quota exceeded". There were options to Ignore or Abort at most of these stages. I chose Ignore and the whole install seemed to complete but I am not able to connect to the database using sqlPlus. I looked at the log files created where I saw a whole bunch of errors in several files. For example in sqlnet log, I saw this error (among others) appeneded below. It seems obvious that some resource quotas were exceeded but I am not able to figure out exactly what quotas should be increased. Any help regarding this would be greatly appreciated.
Thanks.

How many dispatchers are you running?
Increase their number.
First shutdown the dispatcher, like this,
alter system shutdown immediate 'D001';
and then increase them, like this
alter system set DISPATCHERS = '(protocol=tcp)(dispatchers=5)';

Install Oracle Clusterware/RAC Windows x32bit or Windows 64bit ?

Hi,
What is your suggestion to install Oracle Clusterware RAC on Windows.
Why choose Windows 32 bit ?
Why choose Windows 64 bit?
What are the advantages and disadvantages?

Hi,
I definitely recommend 64bit Windows, the principal reason is memory addressing limitation.
In my standpoint do not exist benefits to use Windows 32bit with Oracle Clusterware/RAC.
32-bit processors have address registers that are 32-bits wide (can address up to 4GB physical RAM).
You can to use a workaround by enabling the addressing of more than 4GBytes using parameters in Windows (AWE/PAE). But if I want to use more than 4Gbytes, I'll go to Windows 64bit.
The 4GB addressable space per process is divided into system and user space. By default, the system space is 2GB and the private user space is 2GB. Each user process shares the same 2GB System address space.
The services of the Clusterware, ASM and Listener will consume at least 1Gbyte of memory initially.
If you create an instance to to use 1Gbytes and you have 50 connections you will have problems with connections to the database raising the following error.
TNS-00510: Internal limit restriction exceeded
32-bit Windows Error: 8: Exec format error
TNS-00507: Connection closed
32-bit Windows Error: 109: Unknown errorReason: Problems of memory usage. i.e. Out of Memory.
Another point:
With Windows 32-bit using Clusterware/RAC 11.1 you can set Automatic Memory Management(AMM) feature (MEMORY_TARGET) but you cannot use if you create 2 Instances on same Host.
Check this note..
*ORA-27102, OSD-00031 Unable To Extend Memory_max_target And Memory_target Past 2GB [ID 842881.1]*
Oracle Solution: Please install the 64-bit OS on 64-bit server, hence there is no memory limitations
I belive that is reason wich Oracle not support Oracle Grid Infrastructure 11.2 on Windows 32-bit. You cannot use ASM 11.2 on Windows 32-bit.
Definitely do not exist reason for me to to use Windows 32bit to support Oracle Clusterware.
There are lot services involved wich require memory and a big limitation of memory on 32-bit.
At present all latest CPUs support 64bit. Then install Oracle Clusterware/RAC x64, even when you are use less than 4GBytes memory, you only have benefits.
Benefits of Use 64-bit are:
64-bit versions of Windows have implemented up to 16 terabytes of virtual address space
64-bit programs use the 16 terabyte tuning model (8TB user / 8TB kernel)
No performance penalties for large memory
Unlimited user connectivity
64-bit Windows versions allow addressing of large physical memory sizes without using PAE
*Windows Memory Configuration: 32-bit and 64-bit [ID 873752.1]*
This document gives a better understanding of my perspective.
