Random TNS-12545 errors
Most of the time my customers sqlnet connections work just fine. Every day or so they get TNS-12545 errors between their servers and databases and across database links for about a minute or two and then things go back to normal. The errors occurr at random times.
We are looking at network and server things that might cause a slow response.
This is Oracle 10.
Are there any specific oracle net parameters that would provide a workaround to avoid this problem?
Most of the time everything is okay but once or twice per week an error occurs and the user gets TNS-12545 errors.
This is Oracle 10. I can't post the configuration files.
I think I need something in the OracleNet configuration that would cause OracleNet to wait a little longer on the connection.

)Hi,
a different point: make sure the (host = ) part of your ADDRESS_LIST is correct, it seems the listener tries to bind to a host/port combination that does not exist. Don't use localhost there or nobody will be able to connect to the database which is probably not what you what.

Re:ORA-12545 error (host target)
Can anyone shed some light on this... I have just installed red hat linux 9 and have been trying install Oracle 9.2 (i have followed many instructions from sites and have done all the export cmds etc...). But i keep getting a ORA-12545 error when trying to connect (no target host found)i have looked at the listener.ora file and cant seem to see anything wrong. What else can i do to solve my problem??? Ian.
There are several issues that you have to check out.
ORA-12545: TNS:name lookup failure
Cause: The listener on the remote node cannot be contacted.
Action: Perform these steps:
Verify that the ADDRESS in the tnsnames.ora file and the listener.ora file is correct.
Verify that the listener on the remote node has been started. Enter:
lsnrctl
LSNRCTL> STATUS [listener_name]
listener_name is the name of the listener defined in the listener.ora file. It is not necessary to identify the listener if you are using the default listener, named LISTENER.
If the output indicates the listener is not running, try starting it with the command:
LSNRCTL> START [listener_name]
First than nothing :
1.- Can you get connection locally in the Server ?

Oracle 10gr2 rac, ora-12545 error when configured in shared server mode
Hi i have fresh installation on two node rac on linux, with oracle 10gr2. It is running successfully, when i configure it in shared server mode and try to connect from client it gives error ora_12545:
I have referred the oracle metalink notes and configured the local_listener as well as the remote_listener,
still it is giving the error. I am able to tnsping all the entries on tnsnames.ora,
i m also able to ping the hostnames,
It connects most of the times succeessfully but some times it gives the error.
how to solve this problem,
please help meBasically this error means you misspelled the hostname or typed a wrong IP Address.
Oracle Error :: TNS-12545+
Connect failed because target host or object does not exist
Cause
The address specified is not valid, or the program being connected to does not exist.
Action
Ensure the ADDRESS parameters have been entered correctly; the most likely incorrect parameter is the node name. Ensure that the executable for the server exists (perhaps "oracle" is missing.) If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric IP address and try again.
I suggest you to check the dispatcher instance parameter.

Error list to monitor the ORA,TNS,CRS errors
Hi All,
Greetings ...
Can you list down what are the critical errors we need to monitor in the alert log file,listener log,CRS and ASM alert log files.
Here we need to implement the errors list to the monitoring tool. I am having few errors list.
Listener
tns-12560,tns-12535,tns-12541,tns-12545
ASM

ORA-15096 lost disk write detected
ORA-01243 system tablespace file suffered media failure
ora-4030,4031,7445,0600
Regards,
Prasanna.Hi;
There are may errors avaliable in oracle database.You could type one sh and can monitor your alert.log by checkin ORA* errors.
I suggest monitor ORA-600 or ORA-7445 errors in your alert.log which is i belive most critical errors
Regard

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

03002199037You're attempting to go across SQL*Net. I'm a unix guy so I can't help very much except to point this out.
On Unix I'd either undefine the TWO_TASK environmental variable. Probably a reg entry on 2k.
Or configure Sql*Net.

MARS - Oracle TNS listener errors
Anyone familiar with this:
[pnadmin]$ pndbusage
Program aborted due to: ORA-12541: TNS:no listener
MARS was fine before the holiday weekend. When I came back, I was looking at the summary page and the graph wasn't being drawn. I SSH'd to MARS and did the above.
While SSH'd to MARS (and my HTTPS session still open) I did a reboot and I still get the same error. Also, now when I HTTPS to MARS I get a login page, but the url is: https://10.6.184.116/logout.jsp
The username/password fields and login button are in the upper left corner of the browser window, not in the middle like normal.
So, now I have two problems. The first being my TNS listener error and the second being that I can't log in. It wants me to log out first...ugh.
Thanks,
BobThis sounds like a known issue and if memory serves a developer will need to login and do something, so you'll need to open a TAC case.
