The problem is solved after exprting the parameter ORACLE_SID=<database_name>
in Weblogic startup script.
thank u for the suggestions.

Hi Joe,
I have checked the ORACLE_HOME parameter. There was a differnce. Ichanged to
/oracle/app/product/8.1.7
Now i am getting different exception. But still the standalone codeis working.
any clues why I am getting this exception. I will send the code andthe weblogic
properties file for reference if u need.Good. No, I don't need it. Now make sure the library path that the OS
uses to find
Oracle libraries, and our driver libraries etc., is in the same order
for the
server as for the shell that is successful on it's own. Make sure your
Oracle
client stuff is ahead of any weblogic libraries.

The environment for the server probably doesn't have the same ORACLE_HOME

Also, you should be using our connection pools, and you should avoid
making DriverManager calls in any multithreaded app such as WebLogic.

You said "when i tried tu connect to db with the sqlplus ..."
But you seem to forget to specify which database instance to connect to. Like this:
$ sqlplus <user>@<tns name>
If you have oerr command installed, it can explain the ORA error for you.
$ oerr ora 12545

Error while installing Oracle 8i on RHEL 3.0, ORA-12545

Hi,
I am trying to install oracle 8.1.7 on redhat EL 3.0. Earlier i installed the same oracle i.e 8.1.7 on redhat 8.0/9.0 and it installed sucesfully. The proceudre
i follow for installtion was :

#### thereafter I apply the patch

./setup_stubs
#### Therafter i run dbassist and I create the db and all went well.
When i followed the same procedure in RHEL 3.0 it goes smooth till applying patch glibc2.1.3_stub.tgz but thereafter when i try to create db using dbassist it gives me error like :
ORA-12545 Connect failed because target host or object does not exist.
Even if i tried to run svrmgrl it gives me error
:ORA-12545 Connect failed because target host or object does not exist
Could anyone help me in resolving that ? the same installation procedure works well for Redhat 8.0/9.0
Thanks
Harsh Bhatia

DBCA calls svrmgrl.exe in order to make a startup nomount of the new database and svrmgrl.exe fails during the hostname resolution.
Try to give ipaddress rather than hostname in the tnsnames.ora file.

8.1.5 installs on Redhat 6.1, but ORA-12545 error

I carefully followed all of the installation instructions, and the installation procedure seemed to go as expected. But when I attempt to create a database with dbassist, I get an error:
ORA-12545 Connect failed because target host or object does not exist
Note: This is not a networked machine, but there are two network cards installed in the machine. The hostname is currently set to "localhost.localdomain".
Any ideas?

ORA-12545 error after changing the host name as IP address in Tnsnames.ora

HI,
I tried to connect PHP and oracle in Red Hat linux. I got error ORA-12545 after changing the host name as IPAddress in Tnsnames.ora file. In sqlnet.ora file also i have entry for tnsnames in Directory_Path. I struggled so much but i couldnt solve that. Please give me ur valuable suggestions....

12545, 00000, "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.
Seems you specified wrong IP address.

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.

Ora-12545 strange error

Dear friends
I have one strange error in Oracle 8.1.7 , Windows NT server. We have 4 databases in a same box. All are working fine till yesterday. Today morning I am facing this problem. I can not connect to one database out of four from any client. Getting error "ORA-12545: Connect failed because target host or object does not exist"
Other 3 databases in the same server I can connect from client.
In the server I can connect all four databases without any problem.
I am using tnsping <servicename> from the client, is getting OK.
I Observed the tnsnames.ora in the client , nothing found strange. Because all client machines have this problem.
Pleas advise?

I did both your suggestions
First of all all clients are working properly till yesterday without any problem. Today I faced this problem in all clients around 10 clients same time. I feel it is may be Host machine database /network setting problem. How we can trace?
When I restart Listner using lsnrctl command in server , then I can connect from client using SQLplus but a while only. When I Establish another connection in the same client or from any other client, it won't allow me. Also , connected session getting error.
When I issue lsnrctl status command in server it is displaying like this. Maxnew is the one that have problem.

Hi
Just thought I'd tell the list that I had to add

Try this

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

used type-2 driver for this purpose. This jps works fine in AdminServer but do
not work in DeployServer. It throws the following error

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.

This:

says that your network setup is not correct. You need to resolve that first.
As for Broker setup steps how about the doc or our Data Guard 11g Handbook?
It's 3 DGMGRL commands so I am not sure what 'steps' you need?

This is the text for ORA-12545, there is a problem in your NET8 somewhere.

I have a funny feeling that the problem lies with either:

I have tried everything to remedy this, this is why i am now turning to you guys.
Any and all help is always greatly appreciated.

Hi Guys,
Thank you both for your responses, my findings are as follows:
1. HOST=X.X.COM, ensure host is reachable : PING works and host(s) are reachable.
2. In RAC Env, ensure TNS Name is correctly spelled, spelling fine, i can connect with the tns name (is TNS name same as SERVICE_NAME?) by: sqlplus 'user/user@racenv'; but my efforts still will not allow me to use:
sqlplus 'user/user' it tells me that the host or object is does not exist, does this refer to the actual physical machine or the service name, or the instance name?
All host entries in my tnsnames.ora file refer to the vip addresses of both servers holding the rac installation, and both are resolved just fine, testing with ping; any other way to test this?
tnsnames file contains CONNECTION strings in the following order (does the listener entry need to be in the file? on the machine that i am trying to connect from?):
LISTENER_ORCLTELE =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.9)(PORT = 1521))
ORCLTELE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.9)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = orcltele)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
I tried removing all entries but the entry for MSRAC, but still no joy:
MSRAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.12)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.13)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = MSRAC)
(failover_mode =

Thanks again,
Robert..

It mentions PROTOCOL=BEQ, this should be TCP, is there a way to enforce TCP or disable BEQ??

Cannot connect to DB from remote computer (ORA-12545)

Hello all,
Please help, I am stumped. I am trying to connect to a database located at my work from at home.
I am running into the following issue (see command and error below):
ansichart@ansivm:~/src/perl$ sqlplus aspxdba/********@aspxp2
SQL*Plus: Release 11.2.0.3.0 Production on Thu Jul 18 21:15:09 2013
Copyright (c) 1982, 2011, Oracle. All rights reserved.
ERROR:
ORA-12545: Connect failed because target host or object does not exist
Here is my tnsnames.ora file (I have the service_name censored out for privacy reasons):
ansichart@ansivm:~/src/perl$ cat $ORACLE_HOME/network/admin/tnsnames.ora
aspxp2 =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = orarac9-scan)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = *****************)(UR=A)
I have verified that I can establish a TCP connection to this DB server on the port specified, using the same info from the TNSnames.ora file (see below):
ansichart@ansivm:~/src/perl$ nmap -sT -p 1521 orarac9-scan
Starting Nmap 5.21 ( http://nmap.org ) at 2013-07-18 20:53 CDT
Nmap scan report for orarac9-scan (10.1.13.115)
Host is up (0.0088s latency).
PORT     STATE SERVICE
1521/tcp open oracle
Nmap done: 1 IP address (1 host up) scanned in 0.09 seconds
ansichart@ansivm:~/src/perl$
I have another terminal opened up to a server at work and I can connect to the DB with sqlplus just fine. I verified that the record for this database on the tnsnames.ora file is the same as it is at work.
In conclusion, I can connect to the Database at work, but I cannot at home, even though I am using the same connection information and verified that port 1521 is accessible on this Database server from at home. So why can't I establish a DB connection?
Any ideas?
Thanks,
Ben

This simply means "hostname unknown". In other words, the hostname used for the connection could not be resolved to an IP address.
I have verified that I can establish a TCP connection to this DB server on the port specified, using the same info from the TNSnames.ora file (see below):
You are verifying hostname orarac9-scan only. You are not verifying that the hostname supplied by the Oracle SCAN Listener can be resolved by your platform.
As you are connecting to a SCAN listener, it will do its magic (load balancing/round robin/whatever) and return a redirect to your client driver - telling it where to find the service name the client requested.
So your client driver gets a hostname and port in return. It then attempts to connect to that to establish your Oracle client-server session. If the RAC has been setup with the typical RAC hostnames, your client will get hostnames like orarac9-vip1 and orarac9-vip2 returned. Likely as FQDN too.
This means your platform needs to be able to resolve these hostnames. It does not. Thus the error.
In your platform's /etc/hosts file, define the complete list of RAC hostnames (SCAN, Public and VIP hostnames).

Get ORA-12545: Connect failed because target host or object does not exist

Hi all,
My database is in RAC on a RHEL 5 and oracle 10.2.0.4 release, when i connect from client at the first time it's connected and after exit and connect again it gives the error ORA-12545: Connect failed because target host or object does not exist. and trying to tnsping i can reach the server and connect again it's connected and after disconnect and reconnect it gives the same error.
Here is my tnsnames from windows client:
CDRMGRAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.116)(PORT = 1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.117)(PORT = 1522))
(LOAD_BALANCE = yes)
(FAILOVER = ON)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cdrmg)
In this tnsnames , i'm using the virtual ip address.
Thanks for your help

hi,
check the ping trace.. for how long the connection establish..
check whether its breaking ,.
