Oracle oci8 driver problem

Hello !
I work with Weblogic 701, oracle 9.2.0.1 database, oracle 9.2.0.2 client, and
oracle jdbc drivers classes12.zip
When I connect with the oci8 (not the thin) driver and try to execute the application,
I get this error :
java.lang.UnsatisfiedLinkError: Native Library D:\oracle\ora92\bin\orageneric9.dll
already loaded in another classloader
I have to shutdown weblogic and start it again. If I redeploy my application,
I get the same error and I have to shutdown again ...
and when I connect with the thin driver and try to execute the extract method
on a XMLType object, I always have a sqlException.
I see on the web that the extract method can only be applied with the oci8 driver.
How can I do ???
Thx

Hi. Go to oracle's site and download the very latest appropriate thin
driver for your DBMS, and put the driver ahead of all weblogic stuff in the
classpath the server is going to use.

How to set the oracle oci8 driver?

hello all:
I've set up the oracle thin driver and it works. but when I change to
oci8.it don't work
below is config and errors:
<JDBCConnectionPool DriverName="oracle.jdbc.driver.OracleDriver"
InitialCapacity="5" LoginDelaySeconds="5" MaxCapacity="15"
Name="ocipool"
Properties="user=yanji;password=yanji"
Targets="myserver" URL="jdbc:oracle:oci8:@pg01"/>
Could not load 'oracle.jdbc.driver.OracleDriver
If this is a type-4 JDBC driver, it could occur if the JDBC
driver is not in the system CLASSPATH.
If this is a type-2 JDBC driver, it may also indicate that
the Driver native layers(DBMS client lib or driver DLL)
have not been installed properly on your system
or in your PATH environment variable.
This is most likely caused by one of the following:
1. The native layer SO, SL, or DLL could not be found.
2. The file permissions on the native layer SO, SL, or DLL
have not been set properly.
3. The native layer SO, SL, or DLL exists, but is either
invalid or corrupted.
For more information, read the installation documentation
for your JDBC Driver, available from:

Hello, Jenny I am glad you found your resolution. I too am having problems isung
the oracle 0CI8 driver. My connection pool is creating fine, but my server is
crashing with JVM errors.
Here are my configurations.
DBase=Oracle 8.1.7,OS=Win2000, running 6.1 with Portal 4.0
pool config =
<JDBCConnectionPool CapacityIncrement="0"
DriverName="oracle.jdbc.driver.OracleDriver" InitialCapacity="5"
MaxCapacity="5" Name="ccConPool"
Properties="jdbc.url=jdbc:oracle:oci8:@servername:1521:orcl;user=XXXXX;password=XXXXXX;dll=ocijdbc8;server=orcl;protocol=oci8;dll=ocijdbc8;protocol=oci8"
RefreshMinutes="0" Targets="portalServer"
TestTableName="WIP_TABLE" URL="jdbc:oracle:oci8:@servername"/>
My classpath sets my classes12.zip file first. My path sets %WEBLOGIC_HOME%\bin\oci817_8
and %WLCS_ORACLE_HOME%\bin.
Am I setting the right dll and protocol in my .dll? Where can I find documentation
on these properties definitions?

although I put the classes12.zip into the CLASSPATH.but the weblogic.jar
in
front of classes12.zip.so classloader
load the class from weblogic.jar. so I can use thin driver(weblogic
implements this function with class,but not for oci8 )
..this is really a big pitfall !
put the classes12.zip in front of weblogic.jar .all perfect!

Its not CLASS_PATH it should be CLASSPATH.
when you say oracle\bin and oracle\lib , on what driver is the oracle
folder?I meant to say 'on what drive' not 'on what driver'
you have to specify the full path.
post your startup script here.

1. Dont copy this file oci8jdbc.dll, to bin folder. Make sure
you
place
<oracle_home>\lib in your PATH before starting the server. Make
sure
your
ORACLE_HOME environment varable is set to <oracle_home> folder.
eg. set ORACLE_HOME=c:\ora816 before starting the server.
so you must have done something like
set ORACLE_HOME=c:\ora816
set PATH=%ORACLE_HOME%\bin;%ORACLE_HOME%\lib;%PATH%
2. double check if you set your CLASSPATH something like this,
CLASSPATH=%ORACLE_HOME%\jdbc\lib\classes12.zip;%CLASSPATH%
in the server startup script just before starting the server.
3. start the server the connection pool should work.

I've edited the StartWeblogic.cmd, set the classes.zip into CLASSPATH,and
copied the oci8jdbc.dll to the bea\wlserver6.1\bin. errors stillappears!
my weblogic version is 6.1 and oracle is 8.1.6 .
why the thin driver is ok but the oci driver can not work?
I logined in the oracle website and look for the jdbc.but I find
that
jdbc
all provide for jdk1.2 or jdk1.1. because the weblogic6.1 based
jdk1.3.
I
think i can not use those drivers.
I think my oracle driver is ok,because i installed the jboss and
bas4.5
in
my computer. they all can use oci8 driver properly.and they all
based
jdk1.3.
by the way. I 've tryed added the oracle\bin path inStartWeblogic.cmd,
nothing changed !
again below is my config : I want to know whether my config right?

To use oracle oci8 driver:
You should have classes12.zip in weblogic classpath.
You should have ocijdbc8.dll in your weblogic path..
You can download ocijdbc8.dll from oracle website.

Oracle (OCI8) driver not available!

I have installed DAC successfully. So I start my client and am trying to create a new connection.
I did the following:
1) Clicked Configure
2) by default, Create connection is selected, I clicked Next
3) Entered Name, selected Connection Type as Oracle(OCI8), entered TNS names as ORCL and created new authentication file.
4) Clicked Test Connection and it shows the error 'Can't connect to the database'. When I click Show details, I get the following:

Does multilingual work with Oracle oci8 Driver? I am facing problems with oci8 while thin driver works fine ...

Hi, I am currently working on iPlanet 6.0 SP4 with oracle 8.1.6. I am planning to make my application language independent. while testing I figured out that if i use oci8 driver or oracle, it doesn't support other language characters while the thin driver supports fine. Can anybody help me regarding this? Is this a bug, or some possible configuration issue? Has somebody came across this problem before? How do i go about it ?

We faced same issue. Looks like the native driver does not support the automatic data encoding/decoding from/to database. You can always workaround this by reading everything as byte stream and then by letting java handle the encoding/decoding. But we decided to use type4 thin driver which does this automatically if you set the content type. Anyway we are told that later versions of IAS may not support native drivers, so if you are serious about multi language shift to type4 thin drivers now itself.

Oracle XA driver problem with WLS 7.0.1.0, Oracle 9.0.1

We are using simplified chinese, after swith to bea jdriver, it messed up
all the encoding. So we cannot display Chinese character correctly.
We are using WLS 7.0.1.0, Oracle 9.0.1 on both Windows and Solaris 8
environment, BEA supplied JDK 1.3.1_03.
We have many diffrent problems with oracle drivers:
1. We want to use XA driver to support distributed transaction, However:
* bea jdriver xa messes up with encoding
* when using oracle 901 driver, everything works fince except webservices.
Workshop application access the ejb, then the workshp application sets
isolation level, but oracle driver does not support it and gives error. Is
there a way to turn off isolation level in workshop? I tried manually edit
weblogic-ejb-jar.xml, however,workshop cannot redeploy it after that.
2. When not using XA, oracle thin driver works fine. But we lost XA
capability.
Any work around?

I did try to change the value in this config file as well, but did not help.
In fact, the installation default setting is with
'<transaction-isolation-level>' commented out.
And when I use bea oracle jdriver, it somehow messed up with database
character set encoding, so our Chinese characters could not be retrieved
correctly. And I try to set the encoding of jdriver to 'GBK', it did not
work.

Hello Ma,
The transaction isolation level value for EJBs backing the JWS files is
specified in the <transaction-isolation-level> tag in the
WEB-INF/weblogic-jws-config.xml file of a Workshop project. You can
manipulate this value to serve your purpose.
Please do let me know how it goes.

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).

Actually, I meant a version conflict between the Oracle JDBC drivers (in classes12.zip) and the installed OCI binaries on the same computer. If both the JDBC and OCI dll's those that were installed from the same Oracle distribution media you should not be getting these errors. Double check your path and classpath. Make sure the versions are precisely the same (8.1.7 for example, not just 8i).

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.

Memory leakage with oracle oci driver

I have developed a Solaris8 client/server application using the JAVA IDL CORBA implementation. The client sends requests to the server to update the database (database is Oracle 8.1.7 and I connect to it using oci oracle drivers). Requests are sent one at a time. No concurrent connections. I have a static connection that I establish with database once I start the server. If that connection is lost for any reason (timeout or database faliure) the application tries automatically to reconnect to database. I have noticed that if the new connection to database fails and an sql exception is thrown, memory used by the application process increases. This memory is not garbage collected so application hangs. I tried similar behaviour with the oracle thin driver and things went fine. There was no memory leakage.
I would really appreciate, if you can help me in this since I can't use the thin driver because of failover limitations.

I have noticed
that if the new connection to database fails and an
sql exception is thrown, memory used by the
application process increases.
How have you noticed this?I noticed this using the command pmap under solaris it operating system
every time I test reconnecting to database I go and check the memory used by the application before after attepmting to reconnect:
/usr/proc/bin/pmap [myapp pid] | tail -1
If I'm using normal connection then the memory will be increased by 100KB. If I'm using the OraclePooledConnection class then the increase will be something like 500KB. Again this is if still there is a problem connecting to database. If connection to database is okay then no memory increase at all.
This memory is not
garbage collected so application hangs.
Then it isn't a java problem. When java runs out of memory it throws a out of memory exception.Well I'm not saying it is a java problem for sure. I suspect that it might be oracle oci8 driver problem. I would appreciate if anyone can help in specifying teh source of the error.
I tried
similar behaviour with the oracle thin driver and
things went fine. There was no memory leakage.
I would really appreciate, if you can help me in this
since I can't use the thin driver because of failover
limitations.
I don't understand that last sentence at all.What I mean here is that instead of using the oci8 driver to connect to database I used the thin driver and kept everything else the same. I simulated the faliure to reconnect to database and based on the pmap command observations there was no memory leakage.
I want to know what is needed to be done in order to get a normal behavior once using the oci8 drivers.

Cannot connect using oracle jdbc oci8 driver

I am using Oracle 8.1.5 JDBC oci8 driver, but when try to connect, always got ERROR: java.lang.UnsatisfiedLinkError:make_c_state
With the same code, but change to connect with thin driver, it works fine. Pls tell me the problem. Thank you.

Hi,
Here is the snippet code from oracle,
// You need to import the java.sql package to use JDBC
import java.sql.*;
// We import java.io to be able to read from the command line
import java.io.*;
class JdbcCheckup
public static void main (String args [])
throws SQLException, IOException
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Prompt the user for connect information
System.out.println ("Please enter information to test connection to the database");
String user;
String password;
String database;
user = readEntry ("user: ");
int slash_index = user.indexOf ('/');
if (slash_index != -1)
password = user.substring (slash_index + 1);
user = user.substring (0, slash_index);
else
password = readEntry ("password: ");
database = readEntry ("database (a TNSNAME entry): ");
System.out.print ("Connecting to the database...");
System.out.flush ();
System.out.println ("Connecting...");
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@" + database,
user, password);
System.out.println ("connected.");
// Create a statement
Statement stmt = conn.createStatement ();
// Do the SQL "Hello World" thing
ResultSet rset = stmt.executeQuery ("select 'Hello World' from dual");
while (rset.next ())
System.out.println (rset.getString (1));
System.out.println ("Your JDBC installation is correct.");
// close the resultSet
rset.close();
// Close the statement
stmt.close();
// Close the connection
conn.close();
// Utility function to read a line from standard input
static String readEntry (String prompt)
try
StringBuffer buffer = new StringBuffer ();
System.out.print (prompt);
System.out.flush ();
int c = System.in.read ();
while (c != '\n' && c != -1)
buffer.append ((char)c);
c = System.in.read ();
return buffer.toString ().trim ();
catch (IOException e)
return "";
This code can be run without specifying a TNSNAME connection string, as the oci8 jdbc driver will take localhost as default.
OR
Only specifying the TNSNAME is enough, i.e. edit %ORACLE_HOME%\network\ADMIN\TNSNAMES.ORA file and locate the XXXXX.WORLD entry in the file. This is the TNSNAME entry referred to.
Without TNSNAME entry you can re-run,
%ORACLE_HOME%\jdbc\demo\samples\oci8\basic-samples> java JdbcCheckup
Please enter information to test connection to the database
user: system
password: manager
database (a TNSNAME entry):
Connecting to the database...Connecting...
connected.
Hello World
Your JDBC installation is correct.
Hope that helps.
Best Luck!

Using OCI8 driver with Sun ONE AS7 and Oracle 9

Hi
I am writing a bean that needs to access an Oracle Database.
I have defined in AS7 a connection pool, that looks like:
<jdbc-connection-pool steady-pool-size="8" max-pool-size="32" max-wait-time-
in-millis="60000" pool-resize-quantity="2" idle-timeout-in-seconds="300" is-isol
ation-level-guaranteed="false" is-connection-validation-required="false" connect
ion-validation-method="auto-commit" fail-all-connections="false" datasource-clas
sname="oracle.jdbc.driver.OracleDriver" name="Oracle_EUNDEV">
<property value="user" name="user"/>
<property value="passwd" name="password"/>
<property value="jdbc:oracle:oci8:@eundev:EUNDEV" name="URL"/>
</jdbc-connection-pool>
My code does a JNDI lookup DataSource, which succeeds.
However, the getConnection always fails, and throws the following exception:
[02/May/2003:16:28:06] WARNING ( 794): CORE3283: stderr: java.lang.NoSuchMethodException: setpassword

I used dbping tool from iplanet and could define a new connection and connect successfully,
But trying to use the existing connection always fail with the same 'MissingMethod' exception.
Can someone help?
Thanks a lot
Jean-Noel Colin

Here is your problem:
jdbc:oracle:oci8:@eundev:EUNDEV
the last part is wrong. Driver will see the EUNDEV as password. After @ , just specify the tnsName that you have, no " : "
you do have a property called "password" already.
It should be something like this:
jdbc:oracle:oci8@eundev

Oracle driver problem

Hello,
I'm currently trying to install the Jive forum application on the WAS. The installation itself went very well, but I have a problem with the initial setup.
At a certain point I have to give the DB driver class and the according connection string.
I have a oracle DB installed for this and was using the following driver class:
oracle.jdbc.driver.OracleDriver
As error jive setup gives me :
Unable to load database driver 'oracle.jdbc.driver.OracleDriver' - make sure it is in your appserver's classpath.
I have deployed the classes12.jar as described in
http://help.sap.com/saphelp_nw04/helpdata/en/80/4f34c587f05048adee640f4c346417/frameset.htm
This also did not solve my problem.
Does somebody has some experience with this?
Thanks a lot!
Regards,
Peter

Hi,
how likely is it that your DB connect code produces the problem ? Did you try this question on the database forum ?

Oracle 8.1.5 JDBC driver problem with LONGVARCHAR

Hi, I'm having problem with 8.1.5 release on Solaris with the
JDBC type 4 driver (thin). If I create the following table
create table test1 (col1 NUMBER, col2 LONG);
Using JDBC driver to insert into the second column any string
longer than 4000 characters causing run time exception. The type2
driver works fine, but type2 is slow.
String sql = "insert into test1 (col1, col2) values (1099,?)";
PreparedStatement stmt ;
stmt = conn.prepareStatement(sql);
// create a string with very long value , bigger than 4096
stmt.setString(1,string);
stmt.executeUpdate();
runtime exception:

Hello,
the NSAPI integration works, also the JSP files.
But I have still problems with the Jdriver for my Oracle 8.1.5.
I get the message :

Any ideas or hints about that?
Thanks in advance
