Could not resolve WebLogicHost parameter

Hi,
I am configurated a cluster with ohs+weblogic in host1 and host2.
I have got a httpd.conf with:
<Location /ecu>
     SetHandler weblogic-handler
     #PathTrim /testds
     WebLogicPort 9009
     WebLogicHost ${HOSTNAME }
     DynamicServerList Off
     Debug ON
     WLLogFile /logs/apache/ecu/ohs_weblogic_curie1-1.log
    </Location>
but when I invoke http://host1.atica.um.es/ecu/
I have got this error:
Could not resolve WebLogicHost parameter
Any idea.
Thanks.

Hi ,
Could you please provide the Weblogic Host which should have a fully qualified domain name of the host on which you application is listening.
If your application is listening on the the host host1.atica.um.es then the mod_wl_ohs.conf should have the below values :-
      <Location /ecu>
         SetHandler weblogic-handler
         #PathTrim /testds
          WebLogicPort 9009
          WebLogicHost host1.atica.um.es
          DynamicServerList Off
          Debug ON
          WLLogFile /logs/apache/ecu/ohs_weblogic_curie1-1.log
    </Location>
Once the above changes are made could you please restart the HTTP Server and then try accessing the application.
Regards,
Prakash.

ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect

Hi Friends,
I have created 10g database for catalog.
I kept the tns entry in some other server. Tnsping is working fine.. I can see the result.

Thanks in advance.

Try on the server where it doesn't work:
sqlplus ismdba/xxxxx@"(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = torora60)(PORT = 1522))) (CONNECT_DATA = (SERVICE_NAME = rman09na)))"
or
tnsping "(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = torora60)(PORT = 1522))) (CONNECT_DATA = (SERVICE_NAME = rman09na)))"
(note the double quotes)
If that works then your tnsnames.ora is incorrect on that server.

MS Access .mdb connection using ODBC could not resolve the connect identifier ORA-12154

Dear All,
I'm trying to use MS Access .mdb file as source to my OWB application. I need to connect to the ms access .mdb file first using odbc. Here are the step I do:
1. Define ODBC connectifity
     control panel -> admin tools -> data sources -> System DSN -> Add
     Choose Microsoft Access Driver (*.mdb) -> Finish
     Data source name: msaccess -> Database: Select -> .mdb file location (C:\MSAccess\att2000..mdb)
2. Configure Listener
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)

      (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = hsodbc)
ADR_BASE_LISTENER = C:\app\Administrator
3. Configure Oracle HS
     File name initmsaccess.ora
# HS init parameters
HS_FDS_CONNECT_INFO = msaccess
HS_FDS_TRACE_LEVEL = 1
# Environment variables required for the non-Oracle system
#set <envvar>=<value>
4. Edit tnsnames.ora

    (CONNECT_DATA =
      (SID=msaccess)

ORA-12154: TNS:could not resolve the connect identifier specified Oracle 11

I'm having a slight issue with Oracle 11 R2
Oracle 10g was removed from the machine - The registry was cleared and I couldn't see anything of 10g left.
I then installed Oracle 11 with just the software only, and then created a listener.
Using the Database Configuration Assistant, I tried to add a database but I get the error:

TNS:could not resolve the connect identifier specified

I am at the end of my rope and I would really appreciate some assistance.
I get the error: "TNS:could not resolve the connect identifier specified " from my ASP pages and "Warning: oci_connect() [function.oci-connect]: Error while

I am trying to access these pages from the same server as the database.
I manage to connect to the database homepage, but only after I manually stop and start the database after a restart (why?).

Great post - it has nearly everything needed for diagnosis. Well done.
The database is working, and the listener is listening. The successful tnsping to XE shows me that the client subsystem (at least in the oraclexe) path is set up correctly.
However, two other non-oracle clients (ASP and PHP) cannot see the definition for the XE server. This suggests to me that something is pointing them to another Oracle client software set up
I note that you have C:\instantclient_10_2 in your path - so presumably you had/have installed Instant Client on this machine as well ?
Given that you are on the server box, I don't think you need the Instant Client set up. It's possible that this is what is misdirecting the other clients you are suing. Try taking this out of your path.
If that doesn't work, can you provide the output of a SET command issued from the command line.

Oracle 9i "TNS:could not resolve service name" on 64-bit OS

I have a 32-bit .NET 3.0 application that can run on 64-bit OS using WOW64. When I connect to the database on 32-bit OS with 9i (9.2.0.1) client, everything works fine. However, if I install the same client on 64-bit OS (assuming that it would run using WOW64) and run the application, I get "TNS:could not resolve service name" error.
To make sure that it's not something with configuration, I've installed both clients in the same directory on 32-bit OS and 64-bit OS, and copied the same tnsnames.ora and sqlnet.ora files. I can also connect to the database without a problem on 64-bit OS using SQL Plus. The error only occurs when connection is made via the application, which uses .NET oracle client. The only main difference is that on 64-bit OS, 64-bit version of .NET 3.0 is installed.
Does anyone have an idea why I am getting this error?

Hi, paste in this post your tnsnames.ora and sqlnet.ora files and give us a example tnsping for test your alias database.
Good luck.

ORA-12154: TNS:could not resolve the connect identifier speci

I can make the conection to the db by Loging directly into the Oracle SQL using the same info as my sams.
the conection works fine on our old XP OS....
any idea what i have to do to get this to run on Windows 7
thanks

Hi,
1) Check the tnsnames.ora file you are using, verify that it is accessible.
Eg: On Unix:
- Check if you have a $HOME/.tnsnames.ora file - This will be
used in addition to 'tnsnames.ora'.
- Check TNS_ADMIN is set in your environment.
- There is a readable tnsnames.ora file in $TNS_ADMIN
2) Ensure that the tnsnames.ora file contains a line of the form
'alias=(...)' for the alias you are specifying.
Aliases are NOT case sensitive.
3) Make sure that there are no mismatched parentheses in the
tnsnames.ora file.
     4) Even if TNS_ADMIN is set SQL*Net looks in other locations for
     configuration files. Check the default directories for old (or bad)
     copies of TNS_NAMES.ORA. Eg: /etc, /var/opt/oracle,
     $ORACLE_HOME/network/admin
5) Check the default domain name being used, and the path used to
locate aliases, in the SQLNET.ORA file.
The default domain is specified in the NAMES.DEFAULT_DOMAIN
parameter - this is appended to the alias specified in the
connect string if there is no domain given.
Eg: If NAMES.DEFAULT_DOMAIN=mydom.uk
and a connect to "scott/tiger@mydb" is requested
SQL*Net will look for the alias "mydb.mydom.uk"
If NAMES.DIRECTORY_PATH is also specified this determines where
SQL*Net looks for the alias expansion.
6) If none of these show an error enable client side tracing
at level 16 and see what has been written to the client trace
file. There list of aliases in the trace file under the heading
'TNS.NAMES.ORA TABLE HAS THE FOLLOWING CONTENTS'.
7) If ORA-12154 is returned when selecting over a database link from a
client check that the alias in the link can be resolved in the
tnsnames.ora file ON THE SERVER.
8) If you are connecting from a login dialog box, verify that you are
not placing an "@" symbol before your connect net service name.
9) When going from Windows to Linux/Unix platforms,
you can see <carriage return> <new line> characters at the
end of each line instead of <new line> <new line>. Be sure you
use ascii mode when ftp'ing this between Windows and Linux/Unix.

Ora 12154: TNS could not resolve connect identifier specified

Hi,
I have Oracle 11g (Release 1_32bit) Client on my C:\ drive which connect to a Remote 11g (11.1.0.7.0 - 64bit) server.
I have installed 10g DB Server(10.2.0.1.0) and Oracle 10g Forms(Forms [32 Bit] Version 10.1.2.0.2 ) on my D:\ drive.
When I try to connect to Oracle 10g DB from Forms using "Connect" button, I get following error:
"ORA-12154: TNS: could not resolve the connect identifier specified"
Tns and Listner files both are same in Developer_Suite home and 10g home.
Can someone please help me with this error?
Thanks

"ORA-12154: TNS: could not resolve the connect identifier specified"
$ oerr ora 12154
12154, 00000, "TNS:could not resolve the connect identifier specified"
// *Cause: A connection to a database or other service was requested using
// a connect identifier, and the connect identifier specified could not
// be resolved into a connect descriptor using one of the naming methods
// configured. For example, if the type of connect identifier used was a
// net service name then the net service name could not be found in a
// naming method repository, or the repository could not be
// located or reached.
// *Action:
//   - If you are using local naming (TNSNAMES.ORA file):
//      - Make sure that "TNSNAMES" is listed as one of the values of the
//        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA)
//      - Verify that a TNSNAMES.ORA file exists and is in the proper
//        directory and is accessible.
//      - Check that the net service name used as the connect identifier
//        exists in the TNSNAMES.ORA file.
//      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
//        file. Look for unmatched parentheses or stray characters. Errors
//        in a TNSNAMES.ORA file may make it unusable.
//   - If you are using directory naming:
//      - Verify that "LDAP" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Verify that the LDAP directory server is up and that it is
//        accessible.
//      - Verify that the net service name or database name used as the
//        connect identifier is configured in the directory.
//      - Verify that the default context being used is correct by
//        specifying a fully qualified net service name or a full LDAP DN
//        as the connect identifier
//   - If you are using easy connect naming:
//      - Verify that "EZCONNECT" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Make sure the host, port and service name specified
//        are correct.
//      - Try enclosing the connect identifier in quote marks.
//   See the Oracle Net Services Administrators Guide or the Oracle
//   operating system specific guide for more information on naming.
$
Tns and Listner files both are same in Developer_Suite home and 10g home.Listener files are totally useless in Developer Suite home, since they are server files.

Here's your issue
(HOST=localhost.localdomain)
If you are going to use "localhost" at least fake it by adding an entry in your /etc/hosts files
Example ( add to both servers so they can see each other )
192.168.0.20               primary.localdomain   primary
192.168.0.21               standby.localdomain   standby
Does the "hostname" return localhost.localdomain? Setup something so RMAN has something to connect to.
The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address> <fully-qualified-machine-name> <machine-name>
localhost.localdomain is 127.0.0.1, you don't want that.
Best Regards
mseberg

you have a listener problem at least.
The status request to lsnrctl reports "no service". If the listener does not support any service, no connection.

ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect des

Hello all,
I installed a 10g client on a windows PC, which already had 8i installed.
SQLPlus login works for databases in both environments, but now a 8i database cannot be connected from Visual Studio.
ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect descriptor
I immediately checked both tnsnames.ora, but I don't see anything wrong.
sqlnet.ora has:
SQLNET.AUTHENTIFICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES)
Has anybody encountered this issue?
I'm thinking of de-installing 10g now...
Thanks in advance.

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a service name for a service (usually a database service) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
Action:
- Wait a moment and try to connect a second time.
- Check which services are currently known by the listener by executing: lsnrctl services <listener name>
- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener.
- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener.
- Check for an event in the listener.log file.
Pay special attention to these possible reasons:
- Check which services .......
- Check that the SERVICE_NAME parameter ...........
There's a mismatch between service_name is tnsnames.ora and service_name known by the actual listener.

When using a dblink, the database with the link is acting as a client to the remote database ... exactly like sqlplus running on the db server.
