Can't connect (ORA-12545)

When I run servlet(Application server is Websphere,and it is in the same machine with Oracle 8.1.7/ifs1.1), it can not get LibrarySession.Verbose error message is:
oracle.ifs.common.IfsException: IFS-10620: Unable to construct connection pool
oracle.ifs.common.IfsException: IFS-10633: Unable to create library connection
oracle.ifs.common.IfsException: IFS-10600: Unable to construct library connectio
n
java.sql.SQLException: Error while trying to retrieve text for error ORA-12545
If I run in command line(terminal of the machine), it has no problem.
I have set LD_LIBRARY_PATH env variable in WebSphere and all set all required classpath in WebSphere. Any thing is missing?
My code is:
LibraryService ifsService = new LibraryService();
CleartextCredential me = new CleartextCredential("system",
"manager");
ConnectOptions connectOpts = new ConnectOptions();
connectOpts.setServiceName("IfsDefault");
connectOpts.setServicePassword("ifssys");
System.out.println("after setservicepassword: "
+ (System.currentTimeMillis() - startTime) + "\n");
session = ifsService.connect(me,connectOpts);
System.out.println("Connect done: "
+ (System.currentTimeMillis() - startTime) + "\n");
It throws IfsException in ifsService.connect.

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.

No you don't must use screenshots. At the point you were when you took the screen shot, you had already selected the text for copying. All you had to do was click "edit", then "copy", and you could have pasted the selected text right into your post on this forum.
I just finished writing a blog post about this very error yesterday. http://edstevensdba.wordpress.com/posts/
And it's obvious from other evidence on that screenshot
bash: ./tnsping: No such file or directoryThat you don't have $ORACLE_HOME/bin added to your PATH. You need to fix that as well.
But i don't want to use ORCL,i was create new database that's QLHS

Tnsping ok, but sqlplus can't connect ora-12154

Hello All, I have installed on my linux the 10.1.0.3 oracle client and I can do tnsping to my tnsnames.ora databases but I can't connect with sqlplus... I have an error: ora-12154
I have readed metalink documentation and I think everything is ok, but still can't connect... :( Can anybody help me please?
Here is some extra data:
-My env vars are:
ORACLE_HOME=/home/j0nuntu/OraHome_1
TNS_ADMIN=/home/j0nuntu/OraHome_1/network/admin
TNSNAMES=/home/j0nuntu/OraHome_1/network/admin
-My tnsnames.ora:
TEST =

(CONNECT_DATA =

As I said, tnsping to test or oracle is ok... tnsnames.ora is in the correct path and there it has 775 perms on it. What can be happening?
Thanks in advance.

Also, make sure it is using the correct tnsnames.ora file.
Do you have multiple copies of this file in different directories?
post the contents of your sqlnet.ora file as well.

Oracle RM failing to connect: ORA-12545

Hi,
I am trying to run my application which uses Oracle client 8.0.6 on NCR MPRAS.
I am connecting to DB version. 8.1.7 running on Solaris box
Following are working fine for me which means there is no problem with TNSNAMES.ORA:
1) TNSPING
2) SQLPLUS
3) Applications using embedded SQL calls
But my recent application which uses the Resource Manager ORACLE_XA is failing at xa_open call. It give the error ora-12545.
Am I missing something here? Please help.
Vikram

I don't know Crystal Reports and what it sends to and requests from the database, but that's the formal description of this error:
Error: ORA 8001
Text: maximum number of sequences per session exceeded
Cause: An operation requested a resource that was unavailable.
The maximum number of user sequences per session is specified by the
initialization parameter DC_SEQUENCES.
When this maximum is reached, no more requests are processed.
Action: Try the operation again in a few minutes.
If this error occurs often, shut down Oracle, increase the
DC_SEQUENCES parameter in the initialization parameter file, and
restart Oracle.

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.

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 =

MSRAC =
(DESCRIPTION =

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 = (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

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).

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

suggestions
ok VIPs
can client access the server(TNSPING utility).
or simply ping the server.
if client able to communicate server then check HOSTNAME in listener.ora
is represting correctly your Host.
is hostname map with virtual ip in host file of Operating System if not using DNS.
check ur hostname with command hostname.

Issues while connecting databases-ORA-12545!

Error:     ORA-12170 (ORA-12170)
Text:     TNS:Connect timeout occurred
Cause:     The server shut down because connection establishment with a
     client failed to complete within the allotted time interval. This
     may be a result of network/system delays; or this may indicate
     that a malicious client is trying to cause a Denial of Service
     attack on the server.
Action:     If the error occurred because of a slow network/system,
     reconfigure the SQLNET.INBOUND_CONNECT_TIMEOUT parameter in
     sqlnet.ora to a larger value. If a malicious client is suspected,
     use the address in sqlnet.log to identify the source and restrict
     access. Note that logged addresses may not be reliable as they can
