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.

Can't connect (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: "

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.
hope you can solve this problem,

Existing client (Oracle 8) fail to connect to its server after installed

After installed Oracle 10g XE, my existing client does not work.
I checked its tnsnames.ora, it's still there and the content didn't get changed.
If I uninstall the 10g XE, the existing client works again.
What should I do to avoid this?

I have the following configuration:
OS: Windows 2000 Professional in spanish language
ram=512 MB
Oracle databases: Oracle 8i 8.1.7 on HP-UX servers
Number of databases: 2
Number of instances: 6 (production, test and developers)
transport: TCP
1. Before install Oracle 10g XE:
Oracle Developer 6.0,in C:\ORANT, in english language
- Oracle Forms 32-bit (6.0.35.3)
- Oracle Reports 32-bits (6.0.5.35)
PATH=C:\C:\ORANT\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem
TNSNAMES.ORA in C:\ORANT\NET80\ADMIN points to the enterprise databases in my company
Registry: HKLM\Software\Oracle\Oracle_home=C:\ORANT
2. After Installed Oracle 10g XE (beta 1)
the path now is:
path=C:\oraclexe\app\oracle\product\10.2.0\server\bin;C:\ORANT\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem
The web interface of XE works oK
the C:\oraclexe\app\oracle\product\10.2.0\server\BIN\sqlplus.exe can connect to Oracle 10g XE but NOT to the enterprises databases.
but now, all tools from Oracle Developer (Forms, Reports, PLUS80W.EXE) and third party tools like SQLTools, DreamCoder) cann't connect to the enterprise databases
neither to Oracle 10g XE.
In the registry, the ORACLE_HOME says C:\ORANT
Solution:
1. Modified the path so c:\orant is before the path to XE so:
path=C:\ORANT\bin;C:\oraclexe\app\oracle\product\10.2.0\server\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem
2. Copy from C:\oraclexe\app\oracle\product\10.2.0\server\NETWORK\ADMIN\tnsnames.ora,
the lines:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = mycomputer.domainname.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
and copied into C:\ORANT\NET80\ADMIN\TNSNAMES.ORA as
XE.world =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = mycomputer)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
and Now:
1.The Developer tools third party tools can connect to the enterprise databases.
2.The develper tools and third party tools can connect to Oracle 10g XE
3.C:\oraclexe\app\oracle\product\10.2.0\server\BIN\sqlplus.exe can connect to Oracle 10g XE

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))

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.

Oracle8i ora-12545: connect failed because target or object does not exist

I am trying to get a Oracle8i database working on a Windows 2000

using the Database Configuration Assistant. But cannot access
it. I try and connect through SQLPlus but receive the following

I think ur not configured or installed directory server..
Do this then it will work fine.

It goes smoothly and later it gives linking error. I ignore them at this stage.
#### 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

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.

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 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):

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,

ERROR:

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).

##### thereafter i run installer
./runInstaller
It goes smoothly and later it gives linking error. I ignore them at this stage.
#### thereafter I apply the patch
tar xzf /tmp/glibc2.1.3_stub.tgz
./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

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.

Error Could not connect to the database - ora-12545: tns:name lookup failure

Hi,
I am a tech at a failing company. Unfortuneatly some users still need ADI installed and working with very limited resources to troubleshoot oracle. I am getting the error - ( Could not connect to the database - ora-12545: tns:name lookup failure )when the user tries to log on to ADI. Any suggestions? I would really appreciate it. We are on Windows NT on an NT network. Oracle 8.05 client installed and ADI 6.0.
Thanks, Mary

Copy the tnsname.ora file from Oracle Database serve onto the client PC.
Path: %Oracle_home%\net80\admin\
