Hi, i have windows 7 , 64 bit, oracle 11g R1, obiee 11g.
Trying to connect to oracle 11g db when working on OBIEE rep, but the connection fails when connecting through odbc/oci. Any imput is appreciated.
Thanks,

you must add a TNS names entry to your tnsnames.ora file @ ORACLE_HOME\network\admin
if not open the connection pool add the tns entry starting from "(DESCRIPTION=....

Unable to connect to Oracle 11g server using instantclient_11_1 in AIX

Hi,
I downloaded instantclient-basic-11.1.0.7.0-aix-ppc64.zip from oracle site and used the same for connection to 11g server for testing my application on AIX 5.3 machine. I am also using easysoft driver for the connection. But I am uhnable to connect to Oracle 11g server from AIX 5.3 using instantclient_11_1 client
libraries. I get the error "Could not load oracle libraries". Error is as below:
WARNING: Setup was unable to contact your ORACLE
WARNING: server by using the connection options
WARNING: you specified.
WARNING: Error connecting to DB: -1
WARNING: HY000: [unixODBC][Easysoft][Oracle]Could not load oracle libraries
But I could connect to the same server from AIX 5.3 machine using instantclient_10_2 libraries and same eaysoft drivers successfully.
Looks like there is issue with connecting with instantclient_11_1 client libraries from AIX 5.3. I also tried with using 11.1.0.6.0. Same issue is observed.
Did anybody else face similar issue?
Thanks and Regards,

I you find nobody who has the same problem, here are some hints:
- Try to connect using "sqlplus" from the instant client. If that fails, there is probably a problem with your setup.
- Look if the Easysoft driver supports Oracle 11.1 as client.

ORA-12504 error when connecting to Oracle 11G DB using OCI and instantclient-basic-nt-11.2.0.3.0.zip

Dear Friends,
I am using OCI and instant_client (11.2.0.3.0) in my C++ program (on Windows 7) to connect remotely to 11G database.
While doing a connection using server name as well as servername:port/service_name as connection strings, I am getting error of ORA-12504 TNS:listener was not given the SERVICE_NAME in CONNECT_DATA.
According to instant client FAQ & white paper at http://www.oracle.com/technetwork/database/features/instant-client/index.html, no tnsnames.ora is required for instant client. Then why could I be getting this error?
I ensured that only the instant client directory is in Path environment variable. There was a ODBC driver installed on this same host. Could that be modifying the behavior of instant client?
Kindly guide.
Many thanks in advance for your help and time.
Best Regards,
- ganesh

>>what is the exact connect string you are using?
For connection, I am using the plain hostname on which the DB server is running.
>>are you calling OCIServerAttach before OCISessionBegin?
I am not using OCISessionBegin. For connecting to DB server, I am using the following sequence of OCI calls (in this same order):
1) g_OCIEnvNlsCreate
2) g_OCIHandleAlloc //-- error handle: OCI_HTYPE_ERROR
3) g_OCIHandleAlloc // --- sevice context: OCI_HTYPE_SVCCTX
4) Setting driver name and application name for the session:
    OCISession* usersession = 0;
    ret = g_OCIAttrGet(m_pSvcCtx, OCI_HTYPE_SVCCTX, &usersession, NULL,
                             OCI_ATTR_SESSION, m_pErrHdl);
    if (ret == OCI_SUCCESS)
        ret = g_OCIAttrSet(usersession, OCI_HTYPE_SESSION, (void*)"OCI_DRV", 2,OCI_ATTR_DRIVER_NAME, m_pErrHdl);
        ret = g_OCIAttrSet(usersession, OCI_HTYPE_SESSION, (void*)"ClientApplication", <ub4>(strlen("DataReconScanning")), OCI_ATTR_CLIENT_IDENTIFIER, m_pErrHdl);
5) g_OCILogon() using the user, password and host name, as below:
g_OCILogon(m_pDbCon, m_pErrHdl, &m_pSvcCtx,
                               (text*)user.c_str(), static_cast<ub4>(user.length()),
                               (text*)pass.c_str(), static_cast<ub4>(pass.length()),
                               (text*)host.c_str(), static_cast<ub4>(host.length()));

How to connect to Oracle 11g using thin driver with service name & SID

Hi Experts,
Wish to know whether there is a common way to connect to Oracle 11g server using SID or service name.
Earlier I used jdbc:oracle:thin:@<<server>:<<port>>:<<SID>> for connecting to individual Oracle server instances.
Now I need to connect to Oracle RAC which provides service names. So I need to use jdbc:oracle:thin:@<<server>:<<port>>/<<service name>>.
This connection string is internally constructed by a program and user inputs <<server>>, <<port>> and <<SID>> or <<Service Name>>. Now this requires two different connection strings based on the input whether its SID or service name.
Is there a common connection string for these two? Based on some articles like this, I understood that we can generically use jdbc:oracle:thin:@<<server>:<<port>>/<<service>>, whether for SID and service.
When I tried this format with SID, I am getting the below error. What I tried is jdbc:oracle:thin:@myoracleserver:1521/ORCL, where ORCL is the SID
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
Request your help in solving this. What I want is a single connection string whether its SID or service. Any help is of great value.
Regards
Sunil

Oracle has an entire book for JDBC: The JDBC Developer Guide.
There are chapters that provide ALL of the connection properties and the rules for creating connection urls.

Error while creating a JDBC connection to Oracle 11g using WLS 6.1

Hi
I am trying to connect to Oracle 11g database on Weblogic 6.1 server.
First of all i would like to know if this is compatible?
The environement that i have is this
1. JDK 1.3
2. Database 11g is on remote system
3. Oracle client on my local system ( Connecting to the 11g DB through the client works fine)
4. Weblogic server 6.1
5. Currently the application is connected to Oracle 10g DB and working fine(We are attempting to move it to 11g)
Below are the steps that i followed to create the connection:
1. Made an entry for the datasource in config.xml under <WLS_DOMAIN>/config folder as below
<JDBCConnectionPool DriverName="oracle.jdbc.driver.OracleDriver"
MaxCapacity="4" Name="CADConnectionPool"
Properties="user=abc_proxy;password=proxy_abc;dll=ocijdbc8;protocol=thin"
RefreshMinutes="5" ShrinkPeriodMinutes="10" Targets="CAsvr"
TestConnectionsOnRelease="true" TestConnectionsOnReserve="true"
TestTableName="dual" URL="jdbc:oracle:thin:@gen11t-ora.db.lab.xyz.com:1530:GEN11T"/>
2. Restarted the server.
3. Ran the application and get the following error on the server console:
<Aug 22, 2011 12:39:42 AM CDT> <Error> <JDBC> <Cannot startup connection pool "C
ADConnectionPool" weblogic.common.ResourceException:

The driver being used by your weblogic is too old and incompatible with the DBMS. Upgrade the driver.

First of all: using the word 'urgently' is inappropriate and rude in a forum of volunteers.
Edit your post and apologize publicly for using it.
Secondly your question is a rhetorical one, as it's answer is:
OF COURSE NOT

Error connecting to Oracle 11g Database

Hi All
I am testing .NET connectivity to Oracle 11g and I am not successful for a while.
I've tried to connect to database using library included in Oracle 10.2.0.3 Client and as a result I've got "invalid username or password" error. Then I've tried to use ORAC 11.1.0.5.10beta. I successfully connected to the server, but when I try to exec any query my program hangs.
Both of them work correctly with Oracle 9i database.
Also I've tried Microsoft .NET provider and it connects and executes queries fine (though 3 times slower).
How do you think what is reason or how can I find the reason?

Issue in Connecting to Oracle 11g Database

Hi,
I have installed Oracle 11g database using loopback adapter. (used ip 10.10.10.10). In the drivers file did the following entry
ipaddress computername.domainname.com computername
How can I connect to this database from other computer in the network ex:using sqldeveloper? (When I try it says "Network adapter couldnt establish the connection")
Thanks,
Ramesh

from other computer in the network Oracle version on that computer ?
Did you configure a connection string on that computer ? If so, please post your tnsnames.ora. If not, what did you do exactly ?
Also, from the server post the result of "lsnrctl stat".

jdbc:oracle:thin:@(DESCRIPTION =(SDU=32768)(ADDRESS=(PROTOCOL=TCP)(HOST=abc.hostname.com)(PORT=1525))(ADDRESS=(PROTOCOL=TCP)(HOST= xyz.hostname.com)(PORT=1525))(CONNECT_DATA=(SERVICE_NAME=PQR)))
The issue that we are facing is, the database failover is not working.The application only connects to the first host in the TNS entry.Evertime there is a failure in the connection to the first host,manual steps are required to swap the hosts.
This started happening after we upgraded Oracle DB from 9i to 11g.
We are using the client jar of 9i to connect to 11g. Could this be causing the problem?
Thanks In Advance.

Yes, you are right. Nothing else was updated.
The application still works as expected except the failover.If you are correct then I seriously doubt it has anything to do with java. It would be something to do with Oracle and/or network infrastructure.
If not then it is some small problem with the driver. You can try updating the driver but I wouldn't expect a fix.

Oracle 10g client connect to oracle 11g server

Hi All,
In my system, i have installed oracle 11g server(11.1.0.6.0). while i try to connect to this server by 10g client in my friends system,which is in the same network,it is showing
ORA-12545: Connect failed because target host or object does not exist,
then i tried with other system (using oracle10g client), its showing
ORA-12154: TNS:could not resolve the connect identifier specified
then i tried with one another system (using oracle 9i client) -- its is connected.
what may be the problem. not connecting using oracle 10g client. and also different error.

Hi,
The client version is 10.2.0.1
this version may not be connect to oracle 11g?
If so then which are the client version will connect to oracle11g server(11.1.0.6.0).A 10.2 client will connect to an 11.x database, but the sqlnet.ora and tnsnames.ora files must be configured correctly. The errors you reported are not uncommon and have been diagnosed repeatedly on this forum. Let's not confuse the issue by comparing / copying files from various machines, as that has already created a moving target of error messages.
On the client that is exhibiting the problem ...
Do you have a single ORACLE_HOME? A single TNSNAMES.ORA?
On that machine, at a command prompt, do a tnsping on the service in question. Also try to connect with sqlplus. Copy the entire session -- commands and results -- and paste it all back here.
On the server machine, log on as the owner of the oracle software, and at a command prompt enter the command "lsnrctl status". Again, Copy the entire session -- commands and results -- and paste it all back here.

Connect on Oracle 11g Xe with ADODB c++ and VS2010 (compiled in 64)

Hello everybody,
I develop an application in C++ and ADODB to connect at Oracle 11g XE. I use this connection string : *"Provider=OraOLEDB.Oracle;Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));User Id=MyUserId;Password=MyPwd*;";*
when I compiled in win32, it's run successfuly but in x64 i catch exception : Can not find the provider. It may not be installed.
At this line
hr=m_pConnection->Open(strCs.AllocSysString(),"","",adConnectUnspecified);
someone have an idea ? Thanks for you answer.

Unable to connect to oracle driver

I am unable to connect to oracle driver. My code is as follows --
try {
Class.forName("oracle.jdbc.OracleDriver").newInstance();
} catch (ClassNotFoundException e) {
System.out.println("Can't find class oracle.jdbc.OracleDriver");
System.exit(1);
} catch (Exception e){
e.printStackTrace();
When I run the code, I am getting the 'ClassNotFoundException'. I have JVM 1.4 and have included classes12.zip and ojdbc.jar in the class path.
What am I missing?

or better yet, upgrade to a less ancient driver jar.
The driver classname you supplied is correct for Oracle 9i and later, but the driver jar you use is for Oracle 8. It's also for Java 1.2 (hence the "classes12" name), and seriously lacking in features and performance compared to more modern versions.
Of course if you're stuck with a 10 year old database version you have little recourse but to use it, but no reputable company would use something that old any longer, especially since it's been out of support for ages.
