JDBC connection without Oracle listener running

I was wondering if it is possible to establish a connection using jdbc to a local oracle database if there is no listener running. I know that it is possible to do this through sql*plus by setting the ORACLE_SID environment variable, but if possible I need jboss to use this connection and my dba's are concerned over vulnerabilities if the listener is running.

The TNSListener for the database is required to be running.
If the TNSListener is not running an error gets generated:
The Network Adapter could not establish the connection.

The code itself is fine; the problem is with one of:
1) the connection URL
2) intermediate networking
3) the database itself
1) your connection URL is "jdbc:oracle:thin:@127.0.0.1:1521:orcl"
- is Oracle really running on the default port, 1521
- is the installation SID really "orcl"
2) lots of possibilities, but only a couple are likely
- is TCP/IP configured and running on your host
- is there a persoanl firewall rpduct running? perhaps it's blocking the connection
3) Is Oracle running?
Is the listener running?

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.

HELP! Jdbc connection to oracle ClassNotFoundException classpath issues..

Okay I am a newbie to this but all the other posts concerning this just say add the classes12.jar to my classpath.
I am using websphere 5.0

Please help. ive been working on it for days =(.

If you're running a Web app, put all JARs that your app needs in the WEB-INF/lib directory. That's always in the CLASSPATH.
I don't know WebSphere. Do you really have to edit something to add all those CLASSPATH entries?
In Tomcat, all I'd have to do is put a WAR file in the webapps directory.
Your code needs some work. You're not following Sun's Java coding standards. Capitalize your class name, for starters.
Is the username and password for your database still "scott" and "tiger"? Nice security there.
Your connect method makes a database connection. Do you leave it to users to close it? (You do close your connections when you're done with them, don't you?)
I'd make Connection a data member and create it in a constructor. I'd write a close method to close it up.
Doesn't WebSphere do connection pooling? Do you really want to write your own class to handle this?

(CONNECT_DATA =

Configuring RAC-aware JDBC connection in Oracle SQL Developer?

How can Oracle SQL Developer be configured to properly connect to an [Oracle RAC|http://en.wikipedia.org/wiki/Oracle_RAC] environment, I.E., not just setup to always connect to one of the individual nodes?
[http://programmersjournal.blogspot.com/2008/08/jdbc-connection-string-for-oracle-rac.html] has an example of a classic and the equivalent RAC-aware version of a JDBC connection string. I've already been using a RAC connection string of the same format from within custom Java applications without issue. I thought the same should be configurable in Oracle SQL Developer by setting the "Connection Type" drop-down to "Advanced", then entering the RAC-aware JDBC connection string as the "Custom JDBC URL". However, upon testing the connection, the following error is displayed at the bottom of the dialog:
Status : Failure -Test failed: Io exception: NL Exception was generated
There is no additional information shown on the "Logging Page" view. Using Oracle SQL Developer 1.5.5.
Thanks!

Thanks, Barry. Just F.Y.I., it is working for me now that I upgraded to the 2.1 EA as -K- suggested. I had marked his reply as "Correct", but probably should have left a response indicating my success as well.
Now, if there's anything you could do regarding the [issues around the display performance of CLOBs, etc., in the Query Result view|http://forums.oracle.com/forums/message.jspa?messageID=3906571] , it'd be very appreciated!

JDBC Connectivity to Oracle 8i Database

I'am facing problem in connecting to Oracle 8i server using oci8 JDBC driver provided by Oracle.
The statemnet that gives me error is --
Connection conn = DriverManager.getConnection ("jdbc:oracle:oci8:@" + "MIS", "scott", "tiger");
This throws an exception
java.lang.UnsatisfiedLinkError : make_c_state.
Can anyone please tell me where i'am going wrong?
Thanx in advance

Really need to know the platform on which you're trying to execute the code. Each client will need to have the standard Oracle client software installed (with the NET8 configuration application, which provides the 'drivers')
On Oracle's metalink see some responses
http://metalink.oracle.com/metalink/plsql/ml2_documents.showFrameDocument?p_database_id=NOT&p_id=121922.1
Overview
This example provides a minimal test program used to verify that the client
environment is set up properly for running the JDBC OCI driver in order to avoid
receiving the 'unsatisfied link error' caused by an incorrect LD_LIBRARY_PATH.
Program Notes
Simply copy the code below to a file called Test.java. Compile and run the
file from the client environment that you intend to use for your JDBC
applications.
References
[NOTE:118756.1]
Caution
The sample program in this article is provided for educational purposes only
and is NOT supported by Oracle Support Services. It has been tested
internally, however, and works as documented. We do not guarantee that it
will work for you, so be sure to test it in your environment before relying
on it.

I'm getting Unsatisfied Link Error with Oci 8 Driver ?
First, make sure that the jdbc-oci shared object (libocijdbc8 or liboci80Xjdbc.so etc.) and ${ORACLE_HOME}/lib are in your path. Then, try this Sample Program. Some times, even after the shared object is loaded successfully, you may get errors such as make_c_state symbol not found. This may happen if your CLASSPATH has classes.zip from JRE 1.1.7 or JDK 1.1.6 and your running java binaries from jdk 1.1.3 or so. Make sure everything (LD_LIBRARY_PATH, CLASSPATH, java binaries) is in SYNC.

JDBC Connection to Oracle 8i

Hi All,
I hope someone will help me.
I am trying to connect to Oracle 8i using the JDBC "thin" driver on Windows 2000 prof. The program is compiled successfully but got error "ClassNotFoundException: Unable to find class oracle.jdbc.driver.OracleDriver" when try to run. Please see code below for your review:

 out.println("ClassNotFoundException: " + clsex.getMessage() + " ");
 finally
 if(conn != null)
 try

Can you please also give me precise syntax and explanation for DriverManager.getConnection i.e. DriverManager.getConnection("jdbc:oracle:thin:@satya:1521:satya", "scott", "tiger");
Many thanks in advance for your great cooperation,
Satya

The error is caused by the runrime VM not finding the Oracle JDBC driver. You need to make sure that the file containing the driver (usually classes12.zip) is in the classpath of your application server. Check the doco that comes with your app server to learn how to set this up.
For info about the parameters to getConnection() for Oracle see the Oracle JDBC developers guide and reference.
http://otn.oracle.com/docs/products/oracle8i/doc_library/817_doc/java.817/a83724/basic1.htm#1000881
Since you appear to be using a J2EE app server you'll probably want to use the JDBC connection pooling it supplies rather than DriverManager.getConnection(). Check out the doco that comes with your app server and read the section about DataSource here http://developer.java.sun.com/developer/Books/JDBCTutorial/index.html

JDBC Connection for Oracle

Hello Experts,
I'm having some trouble getting a JDBC connection to work correctly and I am in need of some advice.
Background:
I have setup a test Portal 7.00 SP14 with an Oracle 10.2.0.2.0 database on a Windows 2003 X64 server. The Portal system was up and running and connecting to a WAS6.20 systems. We do not have BI or XI in our landscape.
I needed to connect to an Oracle 10.2.0.3.0 database from visual composer to read some data from tables to do a proof of concept. From what I understand this connection will be a JDBC connection. I have setup a new system using the JDBC template, assisnged an alias, and entered the connection URL . I was unable to connect.
I read that I need to add the driver using Visual Composer. I did so with the following instructions:
Install JDBC Driver
Start the Visual Administrator
Logon at WebAS
Open: Server, Services, JDBC Connector, Drivers
Choose Create New Driver or DataSource on the toolbar
Specify an arbitrary name for your driver entry such as OracleDriver and click OK
Now search for the Oracle JDBC Driver JAR file on your local harddisk.
I restarted the Java instance with SMICM after completing this task Java will not start. Is there anyway to roll back that change to get Java back up and running?
Also is there a better way to go about making this oracle connection?
Best Regards,

Hi,
although [this guide|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/92d80512-0a01-0010-32a3-cd3735bd9275] is for Visual Composer I find it very helpful in setting up JDBC connections to databases. There is a very deltailed section about setting up a system to a MS SQL Server and the relevant data if you want to connect to Oracle:
4.2 BI JDBC Connector to Oracle
Located at:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
Driver: oracle.jdbc.driver.OracleDriver
URL: jdbc:oracle:<drivertype>:@<database>
jdbc:oracle:thin:@myhost:1521:orcl
Hope this helps,

JDBC connectivity to oracle

Hi,
I am making an application on swings and that would involve the connection to oracle 9i DB.
How do I do it and where can I get the driver for oracle.
This is urgent.
Thanks

Google for "Oracle JDBC download". You might have to register to get their JDBC driver. Make sure you have the version that matches your JDK. If you're running JDK 1.4 or higher you'll want ojdbc14.jar.
As far as how to do it goes, you'll want to look at a JDBC tutorial.

JDBC connection to Oracle 10g RAC periodically times out

I've been banging my head against the wall for months now and can't figure out why this is and what's causing it.
We have 6x CF8 servers in our environment. 3 of which work perfectly and the other 3 have the following problem. All 6 machines were installed at the same time and followed the exact same installation plan.
When I configure Oracle RAC data source, some of the machines time-out connecting to Oracle from time-to-time.
Config:
Solaris 9 on both CF and Oracle
CF8 Enterprise with the latest updater.
Apache 2 (not that it's relevant)
6 machines, load-balanced (not clustered), identical install and configuration.
data source config:
JDBC URL: jdbc:macromedia:oracle://10.0.0.3:1521;serviceName=dbname.ourdomain.com;AlternateServers= (10.0.0.4:1521);LoadBalancing=true
DRIVER CLASS: macromedia.jdbc.MacromediaDriver
The problem:
Every few minutes, CF starts hanging requests that deal with a specific RAC only data source. After about 30 seconds, all requests bail and generate this error in cfserver.log:
A non-SQL error occurred while requesting a connection from dbsource.
Timed out trying to establish connection
This happens with any RAC data source on the "bad" servers while the "good" servers don't have this problem. The "bad" server doesn't have any problems with direct (non-rac) Oracle data source.
Already tried:
Moving server connections around on a switch (rulling out bad switch port)
Copying driver from the healthy server (but it's the same installer anyway)
Changed from RAC to normal Oracle type data source - works perfectly. So at the moment I have 3 servers connecting to a specific oracle instance and the other 3 connecting to RAC.
Tried googling and searching forums and even Oracle metalink - nothing I could see relevant to this.
It's a shame that after spending a ton of money on CF8 upgrades and Oracle RAC, we can't really utilize fail-over on the database connection.
Any takers?
Thanks,
Henry

JDBC connection to Oracle 8.16 from Weblogic 6.1

I am trying to connect to an Oracle DB using the JDBC thin driver to Weblogic 6.1
I am getting the following error when starting up the Weblogic server:

Anyone have an idea as to why I am getting this.

If the url fix does not work - try updating your jdbc drivers for oracle 8 (get the latest one). There is a chance that using the older oracle 7 drivers you might encounter some problems.
