JDBC Driver Problems for Oracle 10

Trying to setup an OCI driver in our system but keep getting this response.
INFO 2005-12-02 08:49:40,868 [STDOUT] java.lang.UnsatisfiedLinkError: C:\_EP\coldfusion\cfusion\lib\ocijdbc10.dll: The specified procedure could not be found
INFO 2005-12-02 09:02:35,008 [STDOUT] A non-SQL error occurred while requesting a connection from DEVX2
INFO 2005-12-02 09:02:35,008 [STDOUT] Timed out trying to establish connection
That file exists on that path, so I'm not sure if this message means that it can't find that dll, or a procedure within that dll.
If I set it up to use the thin client... no problems. This is very strange. ojdbc14.jar is on the classpath as well as all the DLLs needed, and I have the client installed on my machine.
What else could I possibly need?

Prior to 10g, Oracle claimed to require the entire Oracle client installation for the OCI driver to work; allegedly you couldn't just pick up the dlls you needed...
With 10g, they've supplied a stripped down "Instant Client" that has just the bare bones stuff (it's still 10MB, zipped):
http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html
They still recommend that you install the client and add an entry to your classpath and path variables rather than trying to pick and choose what you need. I believe the 10g OCI driver is still dependent on an Oracle Net installation (which would be part of the Instant Client install, if required).
BTW, last I knew (last year), Macromedia was discouraging the use of the OCI driver with Cold Fusion.
Personally, I'm not aware of any significant benefits the OCI driver would provide a Cold Fusion installation. The only good reasons I've ever heard of for using the OCI driver are: to connect via IPC instead of TCP/IP (requires the database be running on the same server as the Java program), to use TAF, to use the OCI connection pooling for connection multiplexing, to take advantage of some slight performance gains with stored procedure calls. While not an expert in this area, I think only the first could possibly apply to use with Cold Fusion. The myth that OCI is substantially faster for standard SQL (non stored procedures) has been repeatedly debunked.

Oracle JDBC driver problem for Oracle 8.1.6

i am a newbee to Java, i was trying JDBC programming thru Jbuilder 4.0. now the problem is whenever i am trying the DriverManager.getconnection(), I am getting an error "NO SUITABLE DRIVER". i have downloaded jodbc14.jar(oracle 9i JDBC driver) but so result. what can i do now? any other config issues or is it due to absence of a Oracle JDBC driver of Oracle 8.1.6.

i have set the classpath as mentioned. but no solution.

JDBC Connection Driver Problem for Oracle in a J2EE servlet/class

Hi,
I am having a big problem with setting up a JDBC connection with my oracle database, I have been trying to fix it for about 6 hours now with no joy, I have read that many threads about JDBC, class paths etc.. that i dont know which way is up any more!!
Here is the issue:
(Please bare in mind that I am new to this when posting replies)
I have a Web Application set up as a project in the netbeans IDE. I have a servlet which creates a new object call dbaseFunc which is a public class I have wrote and within this class is a function called getAppConfigCon(). The code for this function is below:
public Connection getAppConfigCon()
Connection con = null;
try
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","cavdev", "password");
catch (SQLException e)
e.printStackTrace();
catch (ClassNotFoundException e)
e.printStackTrace(System.out);
return con;
The database is Oracle XE and is installed on the same machine I am developing on, the database is up and I can connect to it via the netbeans IDE database interface after telling it where the driver is (C:\oracle\product\10.2.0\client_1\jdbc\lib\ojdbc14.zip). Obviously this is just IDE functionality and allows you to browse the database objects from netbeans however I now need to know how to tell the jre where the drivers are, right??
Well like I said multiple forums led me down the classpath route and I have a system environment variable called CLASSPATH set up with the oracle jdbc driver specified as its value, when i run the set command from the command line ( I am running Windows XP Pro) I can see the class path entry in the output as follows:
CLASSPATH=C:\oracle\product\10.2.0\client_1\jdbc\lib\ojdbc14.zip
When I try to run my web app it doesnt assign the connection object with a value, i.e. when i was debugging my con object was null after calling the method mentioned above. After some time debugging i found a ClassNotFoundException was being thrown when the following command was executed:
Class.forName("oracle.jdbc.driver.OracleDriver");
Which I understand is because their is a problem with the class path but what is the problem??? The IDE likes the driver so why doesnt the jre.
I am runnin jdk and jre 1.5, an Oracle XE Database using the netbeans environment.
Some one please help me, I have spent far to much time on this rather than actually working on my project!!!!
Thanks
Keith

Well After 10.5 hrs I actually sorted this myself, the two problems that were throwing me were this:
1. Netbeans does not stop the tomcat server when it finishes running the app, you either have to stop the server from the menu or exit netbeans, until the server restarts it will not pick up on any driver files you add to common/lib
2. You are very right Kiros tomcat does not do .zip files!!!!~~~###
In order to sort this I had to add the oracle driver as a package to my project using the netbeans ide Project > Libraries > New Jar file, this allowed me to access the oracle classes. Then I had to set the server up to deal with the drivers as well, this meant adding the .jar file (not the latest .zip as it wont work) to the bundled tomcat common lib directory and restart the server via the ide (using the start/stop bat files in the tomcat conf directory doesnt work for some reason when its bundled with netbeans!)
Thanks for the help guys but in the end it took 10 hrs a lot of reading and 2 bottles of lucozade to keep the brain goin.

Oracle JDBC driver problem for Canada locale

Hi, there:
I have problem on Oracle JDBC thin driver with Canada locale on client side:
I'm using Oracle9i thin jdbc driver, the nls parameters in oracle database is:
NLS_LANGUAGE: AMERICAN
NLS_TERRITORY: AMERICA
NLS_NUMERIC_CHARACTERS : .,
My java client side is running on Windows NT, which using jdbc thin driver to connect oracle database. If I set the locale in client side as "English(Canada)", it seems return me "French" number format, like ",45" (comma, instead of decimal point) for "0.45". However, If I set client side locale as "English(United States)", it returns me "0.45" as expected.
So, my question: does Oracle JDBC driver always returns "French" number format evenif I set "English(Canada)" as locale? Because Canada have both English and French locale "French(Canada), and English(Canada)". How can I get "English" number format like "0.45" with "English(Canada)" locale setting?
Really appreciated any reply, and thanks a lot in advance
David

Sounds like a question for Oracle Support to me.
Anyway, the way to avoid the problem is to not ask Oracle to format numbers. Get the number directly (via ResultSet.getInt() or getDouble() or whatever) and ask Java to format it.

JDBC driver patch for JDBC driver 8.1.7 on NT to connect 9i db

The patch number 1725012 related to JDBC driver patch for 8.1.7
for use with JDK 1.2.x/1.1.x to connect to a oracle 9i database
now shows patch support for six items but the NT operating
system is missing in the list. Do we need to wait for the NT
support patch release..? or any other work around to address
this bug in the mean time for testing in NT OS.
The JDBC error thrown is
ORA-00600: internal error code, arguments: [ttcgcshnd-1],[0]...

You must include "classes12.zip" instead of "classes111.zip".
Since "classes111.zip" is required only for Java 1
and "classes12.zip" is required for Java 2 which means from J2SE 1.2 on forward.
In adition you might need to inlcude "nls_charset12.zip" as well. Try it first without and if it is not working include it as well.
The required files can you get from the OTN.
This should help

Requirements for JDBC Driver needed for SOA 8 }connection pool

Hi,
I have an AS400 jdbc driver. This driver is JDBC API version 2.x. Also is a Driver Type 4.
What are the requirements of a JDBC Driver needed for connection pool in SOA 8?
Thanks.
Lorenzo Jimenez

You can use pretty much any jdbc driver, including type 2 and type 4.
You need to make sure your shared libraries needed by the driver are available to the appserver when you boot.
Other than that, it is no different than configuring any other driver.

Oracle jdbc driver problems in netbeans 5.5

need help again....i'm experience a problem. the problems are :
i connect from netbeans 5.5 to oracle database express client 10g using jdbc driver ojdbc14.jar. the connection succeded (all the tables appears and i even can view the data). but when i trying to bind data to a drop down list component (with right click to the dropdown list component and then bind data), the dataprovider of that table appear in red color and there's no field appears in that. i'm so confused? i already add the ojdbc14.jar driver to the following path :
1. i create a new class library in netbeans with consist of that driver,
then added to my project (right click in my project then add library).
2. then i added the ojdbc14.jar driver to my tomcats lib at "C:\Program
Files\netbeans-5.5\enterprise3\apache-tomcat-5.5.17\common\lib".
Is there any additional settings in using oracle jdbc driver? Does anyone knows? thanks a lot for the answers...

Hi!
I'm using NetBeans 6.5 and I'm having some troubles to connect.
The steps I've made:
- Create the connection pool in Glassfish, nothing special, just standard parameters (Based on javax.sql.DataSource and including URL, Username and Password).
- Create the JDBC resource associated with that connection pool,let's say jdbc/test.
Now in NetBeans I register the driver:
- New driver -> Find the ojdbc14.jar and from the options that I can choose it shows: oracle.jdbc.OracleDriver and oracle.jdbc.driver.OracleDriver.
If i choose without +.driver+ I got the thin drivers (the ones i want) and if i chosse the one with the other one I got the OCI drivers. So I choose the first option oracle.jdbc.OracleDriver
- Then I go to my project and click New -> Entity Classes from Database and from Datasource I select jdbc/test and it shows the following error message:
Unable to find the driver oracle.jdbc.driver.OracleDriver. Please register this driver in the Databases.
I can fix it if while registering the ojdbc14.jar I select the second option (*oracle.jdbc.driver.OracleDriver*) but with this option I need to specity the connection to use OCI instead of the desired thin driver.
I hope you'll understand and help me somehow

Oracle JDBC Driver Problem

Hi,
When I write code as
Resultset rs = .....
rs.last();
there is no problem for MySQL JDBC Driver, but when I use this code for Oracle, I am getting error with line 2. Why ? Do you know any Oracle JDBC Driver that supports "rs.last()" ? Or is there another way to handle it?
Thanks.

Most of the JDBC Drivers can handle "rs.last()".
The question here is, how do you create a Scrollable ResultSet using DatabaseMetaData, or if this is even possible.
A thorough read of the API docs, for the Classes and methods being used here will answer this question (now that you know what the actual question is).

Oracle 8.1.5 - jdbc driver problem

I am using Oracle8.1.5 (personal oracle) for database. I am trying to retrieve the data from JAVA(JDK 1.3). I use the following driver and its manager in the Java program:-
DriverManager.registerDriver(new Oracle.jdbc.driver.OracleDriver());
Class.forName("Oracle.jdbc.driver.OracleDriver");
However Java is not getting compiled with the following error message:-
Cannot resolve symbol:
package: driver
class: DriverManager
I would request your goodselves to help me out. Thank you in anticipation.
Regards,
Sivaswamy

Thanks for the reply.
Have you tried manually taking the current time and
converting it to the way Oracle is expecting it? If I embed a TO_DATE and format it, it works fine, but I want to stay database independent. Is that want you mean?
Or how about using new java.util.Date() to get the
current date?Not sure I follow you:
--- insertStmt.setTimestamp(5, new java.sql.Date(System.currentTimeMillis()));
Gives an error since setTimestamp expects a java.sql.Timestamp and
--- insertStmt.setDate(5, new java.sql.Date(System.currentTimeMillis()));
Only stores the date without the time.
Thanks again,

plse help me how to connect jbuilder to oracle to access the data. I followed jbuilder doc like from the menu (Tools �� enterprise setup �� database driver ��)
but could not select the driver since it is marked as red (uninstalled). How can I made jdbc driver to available to jbuilder.?. I am using oracle 8i. Will oracle 8i supports jdk 1.3 b��cos I have noticed the jbuilder supports from jdk 1.3 onwards. So plse correct me if I am wrong
waiting for reply
sumesh

thanks for u'r reply.
you mean to say i need to install the new JDBC driver (Classes12.zip and nls_charset12) to the oracle/ora8i/jdbc/lib folder.currently this folder contains only classes102 and classes11.zip files and the corresponding charset only.After instaling the new classes12.zip file do i need to set the classpath?.

since i already declare classpath for oracle JDBC Driver (classes12.jar), why the program still can't found the oracle.jdbc.driver.OracleDriver? please help. thanks.

JDBC Resultset Problem with ORACLE 10.1.0.2

Hello
I have a problem with Petstore GenericCatalogDAO. java. The problem is the behaviour of the resultset object when retrieving data from the database.Below are two synareos one that
works (when) hard coded and one that does not work when parameter values passed into the the result set.
1. The code the WORKS.
statement = connection.prepareStatement("select name from employee where a.name ='SMITH' order by name"
,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
resultSet = statement.executeQuery();
resultSet.absolute(1);
String s = resultSet.getString(1);
The code that gives me a 'exhausted resultset' error which I think means no results
String[] parameterValues = new String[] { "SMITH" };
statement = connection.prepareStatement("select name from employee where a.name =? order by name ",
ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
for (int i = 0; i < parameterValues.length; i++) {
statement.setString(i + 1, parameterValues);
resultSet = statement.executeQuery();
resultSet.absolute(1);
String s = resultSet.getString(1);
There is obviously a problem using these named parametevalues with these preparedstatement resultset, Does anybody know anything about this and a fix for it????
Cheers. Roger

Roger,
It's probably a mistake you made when posting your code, but your query string is incorrect it should be either:
select name from employee where name = 'SMITH' order by nameor
select a.name from employee a where a.name = 'SMITH' order by a.nameIn other words you have prefixed a column with a table alias but have not indicated a table alias in the query.
Also, shouldn't your code be:
for (int i = 0; i < parameterValues.length; i++) {
statement.setString(i + 1, parameterValues[ i ]);
}Or was the "[ i ]" part giving you trouble? (Since "[ i ]" -- without the spaces -- is treated as a text-formatting tag.)
While I didn't try your specific query, I have no problem using "PreparedStatment"s with parameters.
What is your environment? Mine is:
Oracle 10g (10.1.0.4) database on Linux (Red Hat)
JDK 1.4.2
ojdbc14.jar JDBC driver (latest version)
Good Luck,
Avi.

JDBC Driver problem when using JDeveloper 10.1.2 with JDK 1.4

I hope someone can help me solve this problem (which I am sure others have encountered).
The JDK that is downloaded together with JDeveloper 10.1.2 is JDK 1.4.2. However, I believe the JDBC jar files that comes together with JDeveloper 10.1.2 are for JDK 1.2 : classes12.jar, classes12dms.jar and nls_charset12.
What I did was I replaced the JDeveloper 10.1.2 JDBC (JDK 1.2) jar files with the JDBC jar files from JDeveloper 10.1.3 download i.e. ocrs12.jar, ojdbc14.jar, ojdbc14dms.jar and orai18n.jar and then create a new JDBC Library which references these new jar files. I was able to successfully run my applications (under my modified JDeveloper 10.1.2) using this new JDBC library (instead of the original 'Oracle JDBC' library). However, when I created a Database Connection in this modified JDeveloper 10.1.2, the connection was unsuccessful. I received the error message "Unable to find driver: oracle.jdbc.driver.OracleDriver".
My organisation requires me to use JDK 1.4.2 and therefore I cannot use JDeveloper 10.1.3 (which I did not encounter any JDBC problem) as it is certified to run only on JDK 1.5.
Please help. Thanks.

JDev 10.1.2 is quite old, and was never certified for Windows 2008.

MSSQL JDBC driver missing for installation of NW '04 SR1

Hi all,
during the installation of NW '04 SR1/EP6 on a system running MSSQL Server 2000 SP4 SAPinst crashes with the following error:
ERROR 2007-03-06 22:33:34
MDB-05800 <html>Cannot find jdbc driver for MS SQL Server</html>
I searched this forum, the notes and asked Dr. Google but to no avail. Can anybody give me a hint what's the problem, please?
Best regards,
Bernd

Thanks a lot for your help Dan! Your suggestion has shown me the right direction. As I wrote the directory you mentioned was indeed missing. I copied it from another installation and it worked.
At least it seemed to work, but I've got another problem concerning the database connection during the installation. While performing the step "Load Java Database content" SAPinst crashes again with the following output:
com.sap.inst.jload.Jload main
SEVERE: couldn't connect to DB
com.sap.sql.log.OpenSQLException: Could not load class com.ddtek.jdbc.sqlserver.SQLServerDriver.
The strange thing is that I found two different SQL driver on the machine with the working installation! One was located in the installation media directory, the files WebAS is working with are obviously another version, because they have significantly different files sizes!
Does someone have a hint which versions of SQL Server and driver files do work together?
