In Trouble with the Oracle JDBC Driver version - 10.1.0.5.0

Hi !
Without any problems i'm using the Oracle JDBC Driver version - 10.1.0.3.0 to access to the
Oracle database (Oracle Database 10g Release 10.2.0.1.0 - 64bit Production).
But exchanging the JDBC Driver 10.1.0.3.0 to 10.1.0.5.0 brings up the following problem:
the statement
con.prepareStatement(sql, resultSetType, resultSetConcurrency, resultSetHoldability)
(with parameters resultSetType = 1003, resultSetConcurrency = 1007, resultSetHoldability= 1)
returns null !
while using the Oracle JDBC Driver version - 10.1.0.3.0 the statement (with same parameters)
returns a correct PreparedStatement.
Every hint or idea is welcome.
Best regards,
Claus

Claus,
Pardon me if I am stating the obvious, but why don't you use the 10.2 JDBC driver with your 10.2 database? The driver is part of the database distribution. Otherwise, you can download the driver from the OTN Web site.
Good Luck,
Avi.

Sub queries with the Oracle OLEDB driver

We have been testing the Oracle OLEDB driver through VB/ADO on Win2k and have found some VERY disturbing issues. First, some background - version 8.1.7.2, using client side-disconnected recordsets.
A simple query with one or more subqueries is returning no rows when running the same query in SQLPlus returns the desired results. EX: Select a.*, (select Typename from user_types where user_types.type_id =a.type_id) user_type_name from users_group a where user_id = 5
remove the sub-select and the ORACLE OLEDB driver returns a single row. Leave it in and you get recordcount = 0 and rs.eof is true.
Can anyone explain this?
Thanks

Web Logic 6.1 JDBC Pooling with the Oracle Thin Driver

Hi,
We're slowly getting through a WebLogic 4.5.1 to 6.1 conversion for a small application
at my company. Initially, we had trouble getting the Oracle thin driver working.
We've finally cracked this nut. Now we're trying to get pooling working, and
cannot find an example of doing this with the Oracle thin driver.
Would anyone be able to provide:
1. the portion of the config.xml that pertains to building a connection pool using
the Oracle thin driver
2. the two lines of code for loading the driver and getting a connection from
this pool
i.e.
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:myPool", null);
Thanks very much!

You don't usually edit the config.xml unless it is absolutely necessar. Instead,
you can config the pool in the GUI admin console, quite easily. After you successfully
configed the pool in the console, it is written into the config.xml file for you.
Only thing special when config the pool is the name of the driver and the url.
url: jdbc:oracle:thin@dbhost:dbport:dbinstance
driver: oracle.jdbc.driver.OracleDriver
If you prefer, you can also config the pool from the command line. It is detailed
in the "Weblogic Server Command-line Interface Reference".
2. the two lines of code for loading the driver and getting a connection
from
this pool
i.e.
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:myPool", null);
Again, you don't use the connection directly. Instead, you use "Data Source".
Data source in weblogic is just a connection object factory associated with a
JNDI name. You can therefore lookup the data source with the JNDI name and from
the data source object, you get the connectin object. No need to explicitly load
the driver class.
There are plenty of example codes available in the weblogic examples installed
with 6.1, that uses the data source.

How to use the oracle jdbc driver

hi all,
i have use the jdbc driver for oracle before but this time i<m under a hp-ux system and it seems to be different

Oracle.jdbc.driver.OracleDriver() problem

Hi guys. I am taking a dbsystems class at school. We are required to connect to the schools oracle db using this package: oracle.jdbc.driver
the code provided by the profesor is meant to be used by logging into unix accounts on the schools servers and running our java programs remotely. I've been trying to connect by running the java program localy.
i'm using netbeans 4, with java5. netbeans tells me that this oracle.jdbc.driver package doesn't exist.
here is the connection part of the code:
//create the oracle driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
//create a connection object
Connection conn = DriverManager.getConnection("jdbc:oracle:oci:@<blahblahblah>", "<myusername>", "<mysuperduperprivatepassword>");
I have followed many forums and threads on the web. Most of them seem to be fixed just by renaming the classes12.zip file to .jar, placing them in the jre/lib folder and setting the path, but they all seem to be running the java program on the same computer as the database, where as i'm trying to connect remotely. i still tried following the instructions, and this still hasn't worked for me. so, my question is, will this even work since i am trying to connect remotely? and if not, how can i connect remotely to a database using only java? thanks
gyro

when you say build path, do u mean the same folder as my .java source? because it is. I don't know if u need to know this, but it will compile, but not run, and then it will print the above mentioned error. but in netbeans, it just tells you ahead of time why it wont run if u try to run it.
anyways, from what i understand from what u wrote, i will need to use the thin driver...now that comes with the oracle.jdbc.driver package, but i just need to use a different call, right? like, instead of oracle.jdbc i would need oracle.thin, is this what u mean? and if it doesn't contain the thin driver, where can i find it? i found it onces before, but that was completely by accident. can someone supply a url? thanks

Multiple versions of the same JDBC driver - OK ?

Hello
We are using SJSAS 8.1 on our production server, it makes access to an Oracle database for user authentication and thus we have a copy of the Oracle thin driver ojdbc14.jar located in the directory.
<sjsas_install>/lib
Each of our web applications also access an Oracle database and thus the build of each web application includes the same oracle jar file in the directory
domains/domain1/applications/j2ee-modules/<name_of_web_app>/WEB-INF/lib/
This is all good and it works OK. In a perfect world where CLOBs had not been invented that would be the end of the story.
However in order to get around the nightmare of JDBC, Oracle and CLOBs I am contemplating using a different version of the JDBC driver for one web app only.
If I were to build one of the web apps to include a different revision of the Oracle JDBC driver, what are the chances of that web application sticking to its intended version and other applications sticking to theirs ?
We currently use Oracle's JDBC driver version 9.2.0.8 I am contemplating using 10.2.0.3 but I do not want to mess with the version used by other web apps.
Any help you can give me would be very much appreciated.
Thank you

Hi Kim,
May be you can try this and see if this works for you. I am not 100% sure if it will work for you, but worth a try I guess. Create a Test WebDynpro project and try the following steps on this project. If they work out correctly and serve the purpose for you only then try them on your actual Web Dynpro project.
1. Create a test Web Dynpro project say "TestWDProject" with Component say "Comp1" and the default views and windows etc.
Also create some working application our of this component and Windows using the Context.
2. Right click the "Comp1" and select Copy.
3. Right click 'Components" node in the project structure and select "Paste"
4.This step will try to paste the copy of Comp1 as a new Component.
5. You can change the Name and Package of the Component.
6.Similarly you'll get the prompts for views,windows etc.
7.Once you have copied everything, Just check if everything looks good.
8.Now you can create a new Application using this new component and the Component Interface View and Deploy it.
9.Test whether the Application created out of this copy works same as the original component.
You can also try to create another Web Dynpro project and paste the Comp1 in the Components node of that new project and perform the same steps.
Again, try with these Test Projects and see if this serves your purpose before applying the steps on actual projects.
Regards,
Ajay

How do I determine JDBC Version? - oracle.jdbc.driver

(new oracle.jdbc.driver.OracleDriver());

DON'T import the Oracle packages.
That's all hidden from you by the java.sql code. All you do is register the driver and get a connection:
Class.forName("driverClassName");
Connection connection = DriverManager.getConnection("url", "user", "pswd");You might have a "ClassNotFoundException" in your future. I'll bet the JDBC JARs aren't in your CLASSPATH. Make sure they're JARs, not zips. Oracle used to have everything in classes12.zip, but now they've gotten smart and put them in JARs for 9.2.0.1. - MOD

What version of Oracle JDBC driver

I need to know the version of the Oracle JDBC driver to use. I am using JDK version1.2, Oracle version8.0.5.

Subha,
You should be able to use any driver that directly supports JDBC 2.0. A Type-4 database-specific driver is not necessary.
Openlink Software provides a Type-3 JDBC 2.0 Driver Suite. Try a free non-expiring limited seat license at http://www.openlinksw.com under Software Availability and Download - Multi-Tier Download.

[Oracle JDBC Driver]This driver is locked for use with embedded application

Hi
I installed Sun Java Studio Enterprise 8, and am trying to connect to my Oracle database using the attached tutorial code.
The code compiles fine, but I get the following error whenever I run the file: [Oracle JDBC Driver]This driver is locked for use with embedded application
I don't understand what is happening.
Using the Runtime navigation panel on the upper left of the IDE screen, I can right-click and connect to the database, and navigate database files, using the Oracle JDBC Driver that came with JSE8.
Name: Oracle Driver
Driver: com.sun.sql.jdbc.oracle.OracleDriver
Database URL: jdbc:sun:oracle://JAZZPUP:1521;SID=REPO
If the driver is installed, and can be used to connect to a database by right-clicking on the database definition in the Runtime panel, why can't I connect to it just using java code in the IDE. I would expect both methods to work or to fail, not one of each using the same IDE.
Many thanks and take care,
Shayne

http://swforum.sun.com/jive/thread.jspa?threadID=51057&messageID=188210
To summarize - the DataDirectDriver that is shipped with the IDE seems to be locked to be used inside the IDE only because of some licensing issues etc..
That's weird, I agree. I will raise a question on reasons for such a behavior.
The solution would be to use Oracle's own driver, that is distributed at no charge from their web site - http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html

HELP!!! Cannot deploy J2EE application with Oracle JDBC driver...

Hi,
I am writing a J2EE application which (in theory, at least)
connects to an Oracle 9i database.
I have written a simple Java test app utilising only the
java.sql package classes (e.g. Connection, ResultSet) to directly
connect to the database. As long as the classes12.zip is in the
CLASSPATH it works fine.
Now I have written an Enterprise application (SessionBean,
Remote and Home interface and Client) which I am attempting to
deploy via deploytool.
If I include just the client jar and EJB jar in the application
it deploys okay but when I run the application (using runclient)
it produces the following error:
java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver
(It is nested within other error output but that is the core
issue).
However if I try to include the JAR libraries into the app
(classes12.jar and nls_charset.jar from $ORACLE_HOME/jdbc/lib),
then I get the following output from deploytool when I hit the
"deploy" (or "redeploy") button:
Deployment error: invalid entry compressed size
(expected 14411 but got 14580 bytes)
Can someone please tell me what is going on???
How can I deploy the J2EE application including the Oracle
JDBC Driver???
My only other option at the moment is to place all the function-
-ality in the client and not use the J2EE framework.
Any help is greatly appreciated.

OK Ben,
I admit I'm a bit confused. Let me see if I understand where you're
coming from.
You have written a J2EE application that includes a session bean,
correct? If so, your session bean needs to be deployed to an EJB
container. What container are you using? The Oracle 9i database
has an embedded EJB container which (theoretically) you can use.
However, as far as I know, Oracle recommends you use OC4J as the
EJB container. So again I ask, what EJB container are you using?
If, as you say, you are new to EJB, then I think you should
immediately start working wiht OC4J as your EJB container.
Did you look at the tutorial link I gave in my previous post? It
explains -- step by step -- how to create, deploy and run a J2EE
application using OC4J as the EJB container. It also has links to
introductory material for people without little knowledge of J2EE
and EJB.
I have 9iAS Enterprise Edition and 8.1.7.1.0 database server (and
OC4J) installed on my SUN machine. I cannot find any of the
utilities you mention -- "j2eeadmin","runclient" or "deploytool".
What Oracle software have you installed? What are the versions?
What platform are you using?
A J2EE application (according to the specification from SUN)
consists of modules. A module can either be a client module or an
EJB module. A client module can either be a java application client
or a web-based client (servlet or JSP). A J2EE application usually
contains one client module and one EJB module. A J2EE application
needs to be deployed to a J2EE container.
Hopefully the J2EE picture is becoming clearer. I think you need
to read some introductory material regarding J2EE if you intend
to become proficient at it.
I feel that you are under the impression that a J2EE application
is a glorified JDBC application. It isn't (as far as I'm aware).
Good Luck,
Avi.

How to config the CLASSPATH in Win2000 server for JDBC(oracle.jdbc.driver,*)

I am using the OS: Win2000 Server.I need to connect to some remote DataBase,but I
don't know how to config the driver in the CLASSPATH environment variable, my Problem is: when I import the oracle.jdbc.driver.OracleDriver ,and run the program, it warns to me that it cannot find the class,and i know i didnot config the CLASSPATH in environment variables, so I want someone to tell me how to config it ,and where should the file "class12.zip" be placed !
Thank you! maybe the problem is a piece of cake for you ,but now i do not know how to deal with it!

SetLoginTimeout behavior with the Oracle driver

Hi,
I noticed a number of posts on Metalink indicating setLoginTimeout() does not work with the Oracle jdbc drivers. It is documented as such in the 8.1.7 JDBC doc. But I am wondering if this is still true with the 9i drivers.
If so are there any workarounds to generate exceptions or recover gracefully when the db machine is down or the network connectivity to it is down ??
It seems like a fairly drastic flaw in the drivers if it is not able recover from system down type situations.
- Manish

I've seen you've been posting the same message in MetaLink, and, again, no answer from Oracle so far.
It looks like we're having the same problem. In our environment, cross-network connections are being broken down by our firewall, and then the connection hangs forever when the next statement is issued. I wanted to solve this by telling out Java people to use a timeout.
In case you have any news on this, I'd be happy to hear about it.

Oracle jdbc driver spending 40 seconds to make connection to Oracle db 11g

we are using weblogic 10.3.3 and teh default Oracle11.1.0.7 Driver ojdbc6.jar to talk to Oracle db 11.2.0.1
After reviewing weblogic logs I see that it takes 50 secodns for each connection to db
HHere is a snippet (note I put in a 10 sec login dleay as i was experimenting, butt eh problem still occurs with or without login delay)
<Dec 21, 2010 1:28:19 AM GMT> <Info> <JDBC> <BEA-001516> <Connection Pool "acm_repository" connected to Database: "Oracle", Version: "Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

There is someting wrong in this environment
I donwloaded the _g version fo teh exact same driver and had weblogic use it so I could generate verbose logs
Here is a snippet fo teh oracle drivers verbose log file . If you notice the key parts
it seems like its spending 40 second to make the connection, goes into a setConnectionDuringExceptionHandling method and creates the connection
can someone shed light on what causes itto go into an exception state
This happens for each and every connection but only in one specific environment
we have other environments which seem towork fine with the exact same product versions except for this environment
Thank you for any guidance on troubleshooting this further

I would file an oracle jdbc bug to begin with, but I am guessing the driver is simply waiting
for the DBMS to respond, so yo may need a good DBA to see what the DBMS thinks is going
on at the time. I did hear of a case where the DBMS was doing some auditing, logging
some info during every login. This info was being written to an OS file which just happened
to be remote-mounted and would occasionally take 30 seconds, which caused connection
requests to timeout at the driver end.... WebLogic is just asking the driver for a connection
using your properties, so it's not involved directly with the problem....

In Trouble with the Oracle JDBC Driver version - 10.1.0.5.0
