ORA-12545 error in deploy server

Hi
In my development environment, we are having a Domain per application and each
domain will have one AdminServer and one DeployServer. Admin Server will be used
by administrator and DeployServer will be used by developers. All the user developed
application will be deployed in deploy server.
I wrote a small jsp which connects to database and retrieves some data. I've
used type-2 driver for this purpose. This jps works fine in AdminServer but do
not work in DeployServer. It throws the following error
java.sql.SQLException: Error while trying to retrieve text for error ORA-12545

I am using SunSolaris 2.8, Weblogic 6.1. Also I have added classes12.zip in the

Please advise me why this error is coming and how to solve the problem.

Hi Kiran,
Your oracle client on the managed server has not been
set up properly. Make sure you have identical tnsnames.ora
files both on Admin and managed servers.

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 ?

ORA-12545 error in rac, local&remote listener

Hi,
We have an 10g Release 2 RAC system. We usually take
ORA-12545 Connect failed because target host or object does not exist tips
error message. I think tnsnames.ora file is correct, I can achieve to send tnsping message. And I think the host file is alaso correct, I am successful to send ping message to the ip in the host file. And we are noticed that cpu utilization of one RAC node is very bad. Do you that these two problem can be related? I searched the error message on internet. I think this link is interesting:
http://www.ardentperf.com/2007/04/02/local_listener-and-ora-12545/
But I do not fully understand the article. Because I do not know the local&remote listeners.
Can you help me?

Mapping with Match and Merge operater giving ORA-06550 error while deploy..

Created a simplet mapping to source from Customer table to tstcustomer table thru' Match and Merge operator. The mapping validated successful but giving ORA-06550 line x column y error while deploying the mapping.
It is a simple mapping consisting of source Customer table, Match and Merge operator, tstcustomer target table.
Could anyone advise me on how to resolve this?

The test mapping basically consists of :
source table - sh.customers
target table - tstcustomers (similar to sh.customers)
Match-Merge operator.
The mapping validation was successful but when attempt was made to deploy, its giving errors starting with ORA-06550.
I saved the code and executed thru' SQL Plus and the error details are as follows:

For your info, the same mapping without Match-Merge Operator is getting deployed and executed successfully.
But with Match-Merge operator, after setting Match bins, Match rules, Merge rules etc the mapping is validated successfully but errorring out while deployment.
Pls advise on how to resolve this.
I understand that the Match-Merge Operator gives Pl/Sql output from the documentation.

What version of gcc are you using?
Check out this link: http://www.redhat.com/archives/taroon-list/2004-June/msg00030.html
All 8i and 9i releases are built with 2.9x versions of gcc, so you might have to downgrade gcc in order to get 8i running.

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 me

Basically 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.

ORA-00439 error when deploying a simple dimension

Hello,
I am using Oracle Warehouse Builder 11g SE to try to implement a simple data warehouse.

ORA-12545: Connect failed because target host or object does not exist(EBS)

Hi All,
We are using Oracle EBS R12 on Linux x86 Enterprise Server.
We have installed vision database (both apps and db on same machine)
Host name: ERPDEV
IP:192.168.1.211
We can connect from client machines to our database using sqlplus i.e.
sqlplus apps/****@vision
Similarly tnsping is also successfully returning results.
Also following commands are returning results
ping erpdev
ping 192.168.1.211
ping erpdev.domainname.com
All above commands are running fine.
However we are trying to create new "Legal Address Entry" through "Legal Entry Manager". After filling all the details like Location,Country,City etc, when I push the apply button, getting following error messages:
ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1674 ORA-12545: Connect failed because target host or object does not exist in Package xle_legal_address_swi Procedure create_legal_address
I dont know why this ORA-12545 error is occuring through application although all of the above tests are running fine from client terminals.
Do any one have any solution for this???
Thanks

Random Occurrence of ORA-12545

Hi,
We are having trouble connecting to an Oracle 10g database. We receive an ORA-12545 error at what seems like random intervals.
We are trying to connect from 2 different places. 1) Using a DBLink in a Sql Client tool called AquaData and 2) On an Informatica server using an Informatica provided ODBC connection .
A) Below are the details in the TNSName.ORA file used by Aqua Data and Informatica:
PROD_SERVICE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = IP_XXX_1)(PORT = YYY))
(ADDRESS = (PROTOCOL = TCP)(HOST = IP_XXX_2)(PORT = YYY))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PROD_SERVICE)
Where the XXX's are IP address for two different servers and YYY are port numbers.
B) The prod service goes down for 30 minutes, every 90 minutes. However, the server and the listener port are "UP" all the time.
C) We are able to ping, tnsping, telnet from the Informatica server to the oracle server as well as from the Client machine. We are able to telnet and tnsping when the Oracle service is down. (In the 30 minute window), from the Client machine. We have not tried this yet from the Informatica server.
Details/ Observations about Place 1 (Sql Client/ Aqua Data):
1. We have created an DB Link connection to the database causing issues and used that to query from our factory database in Aqua Data.
2. Few times (very random) we have encountered "ORA-12545" error when we run a query.
3. We have observed that when we run a query in the 30 minute window (when the database service is down), we get ORA-01033 or ORA-12545 error randomly.
Details/ Observations about Place 2 (Informatica Server):
1. We have made the same TNS name entry in Informatica server and we have created a ODBC connection, exactly in the same way we configured the connection for SQL Client.
2. When the server is UP, and we kick off the jobs, we get the ORA-12545 error 80% of the time.
We have tried to correlate the occurrence of the error with the number of parallel connections/ different times during the 90minute window, but we were unable to find any conclusive relationship.
Can someone please help us understand the error and resolve the issue?
Thanks!!

From the error docs, an ora-12545 is "Connect failed because target host or object does not exist".
Don't know how that can be made any more plain, the client software is not communicating with the specified host. Verify that the IP addresses are correct.
Three bits of information are required for a client to connect with a database- host, the listener port number, and the ORACLE_SID or instance SERVICE_NAME. Looks like RAC with load balancing so you'll be needing the service name.
The load balance part could be misleading, even with client "try an address in random order" check box enabled, it could very well be always trying the first entry of the ADDRESS_LIST stanza.
So its possible the "random" part is when one of the nodes is down. Or could be another cause, a large batch or some other kind of job blocking or some other pinch point is getting scratched.
Start with trying one client using just one of the IP address, another client specifying just the other. A "random" problem can be impossible to pinpoint.
Examine the symptoms, list possible problems, then test and discover the cause.

ORA-12545; Can't connect because object doesn't exist

For the life of me, I can't figure out why I can't log into the server from my client. I get the ORA-12545 error. I can TNSPing the server from the client as well as ping the client.
Can someone please give me a trick to test which layer is causing the problem. Can't find docs on 8i. I'm using 8i.
Thanks in advance,
Bob

Hi,
Please search tnsnames.ora file in your computer. I hope you can find two copy of it. if so please make sure the tns name parameters are correct in both file.
hope you can solve this problem,
