Oracle JDBC Drivers

We are extracting blobs from an 8.05 database. The following statement works only with an older driver for a version I'm not sure whar it is(size is 1419KB, date is 11/3/00 at 9:25AM).
Nothing special in the sql just extracting the column.
pBlob = (oracle.sql.BLOB)rset.getObject(1);
This works fine with the above mentioned driver. All other drivers I have tested 8.15 for 8i, 8.05, 7.34, 8.04, etc. all give the network datatype unsupported error at this statement. I tried the various examples but they were for the oci8 drivers and did not work with thin.
We use the thin(type 4) driver.
Do the new drivers not support the BLOB type for thin?
Does anyone know which driver version and database that the one I described is from?
Thanks.

user452131,
Yes, there are differences between the Oracle 8i JDBC drivers and the Oracle 9i JDBC drivers.
If you haven't already done so, I suggest perusing the following Web page:
http://www.oracle.com/technology/tech/java/sqlj_jdbc/index.html
Good Luck,
Avi.

Oracle JDBC Drivers 8.1.6.0.1

In the readme file of Oracle JDBC drivers 8.1.6.0.1 (http://technet.oracle.com/software/tech/java/sqlj_jdbc/files/Readme_01.txt)
it mentioned that it supports "connection pooling" and "distributed transactions".
Later on in the same file under "Oracle JDBC Connection Caching", it says it "facilitates" users in their own connection pooling. Does this mean there is not complete implementation of connection pooling in the driver and users has to do the work themselves?

As I understand, JDBC transaction is connection based and uses Oracle internal transaction manager. In order to do "distributed transactions", I must have at least two connections open at the same time each to its own database instance. How does the two connections coordinate the transactions? I thought in order to support "distributed transactions", one has to build a higher layer to encapsulate the two connections and therefore coordinate the distributed transactions. Any examples will be welcome.<HR></BLOCKQUOTE>
The two branches of the transaction are coordinated using 2-phase commit.

Yes, Oracle JDBC drivers do support connection pooling. Download the latest drivers to get samples and refer doc for more details.

Oracle JDBC Drivers with Tomcat

I try to connect to Oracle DB with the JDBC Drivers throught Tomcat JNDI access.
I've tried with the oracle.jdbc.driver.OracleDriver and I have an UnsupportedOperationException when calling the getConnection() method on ma dataSource ref.
So I've tried with the oracle.jdbc.pool.OracleConnectionPoolDataSource and I have an java.sql.SQLException:
Cannot create JDBC driver of class
'oracle.jdbc.pool.OracleConnectionPoolDataSource' for connect URL
'jdbc:oracle:thin:@(description=(address=(host=meditws322)(protocol=tcp)(port=1521)
)(connect_data=(sid=HABILLE)))'
Please help I'm about to break down

Thanks for your reply. I use Oracle JDBC driver. The XSQLConfig.xml was changed to have the following setting:
<connection-manager>
<factory>oracle.xml.xsql.XSQLOracleDatasourceConnectionManager</factory>
</connection-manager>
I'm using Tomcat 4.1.x and Apache Commons DBCP Datasources with org.apache.commons.dbcp.BasicDataSourceFactory. The configuration file does set driverClassName to oracle.jdbc.driver.OracleDriver. All other queries embedded in .xsql files work great, I only have issues with queries containing CURSOR() statements. If I switch back to built-in database connectivity, by changing XSQLConfig.xml and connection parameters in .xsql files everything is working again. When I attempt to use DataSources, I get things like this "oracle.jdbc.driver.OracleResultSetImpl@15780d9" instead of nested XML. The non-nested portion of XML looks fine also, so it is retrieving the data from the database properly. Please let me know if I can provide any additional information that could help in resolving this. Thanks in advance!

Bug in Oracle JDBC Drivers with {ts ?}

Oracle fails to set bind variables correctly when using the {ts ?} in an insert. It works ok if you use {d ?}.
Ex:
String st = "INSERT INTO BL(NM,TSTAMP) VALUES (?,{ts ?} )";
System.out.println(dbConn.nativeSQL(st));
java.sql.PreparedStatement stmt = dbConnn.prepareStatement(st);
stmt.setString(1,"test");
stmt.setString(2,"2000-08-18 09:33:45");
int xx = stmt.executeUpdate();
Oracle Reports:
INSERT INTO BL (NM,TSTAMP) VALUES (:1,TO_DATE (?, 'YYYY-MM-DD HH24:MI:SS'))
ConnectionPoolManager failed:java.sql.SQLException: ORA-00911: invalid character
Notice the ? doesn't change to :2.
Whoops.
Also when does Oracle plan to implement {fn }
scalars. There are work arounds but they are not portable. If not soon we will switch our suggested database for our clients.

Oracle jdbc drivers - cannot resolve symbol

while i'm not new to java, i am new to jdbc. need to connect a java app to an oracle database (hosted by a 3rd party). i have all the connection info. i've crafted a test program, but cannot get it to compile.
here's the code:
import java.sql.*;
public class SimpleJDBC
     public static void main(String[] args) throws SQLException, ClassNotFoundException
     Class.forName(oracle.jdbc.driver.OracleDriver);
     System.out.println("Driver loaded");
     Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@database.host:1521:class"); //, "username", "password");
     System.out.println("Database connected");
     Statement statement = conn.createStatement();
     ResultSet results = statement.executeQuery("select first_name, last_name from user_tbl where last_name = 'Kendall'");
     while(results.next())
          System.out.println(results.getString(1) + "\t" + results.getString(2));
     conn.close();
}i've set the classpath to the location of the ojdbc14.jar, and it shows in the classpath when i do a "set" on the cmd line. i've tried it in netbeans, eclipse, and straight cmd line.
i always come up with the same message (cannot resolve symbol) on the line where i call Class.forName(oracle.jdbc.driver.OracleDriver);.
i've tried compiling and setting the classpath at the same time. i added the ojdbc14.jar to the compile/build paths in both the ides. i even tried using the old classes12.jar. nothing has worked.
i can't figure out what else there is. within the ides, the intellisense will actually let me put that line in (piece by piece), but then it shows an error.
any suggestions?

Place the string name of the driver in quotes.

Multithreaded clients and Oracle JDBC-drivers?

Are the thin and OCI8 drivers for Oracle multithreaded? (I know they're thread safe)
I.e. Can many threads share the same Connection object (and statement objects) to do their requests without the requests being serialized to the DB?
Sun's javadoc of package java.sql says:
We require that all operations on all the java.sql objects be multi-thread safe and able to cope correctly with having several threads simultaneously calling the same object.
Some drivers may allow more concurrent execution than others. Developers can assume fully concurrent execution; if the driver requires some form of synchronization, it will provide it. The only difference visible to the developer will be that applications will run with reduced concurrency.
For example, two Statements on the same Connection can be executed concurrently and their ResultSets can be processed concurrently (from the perspective of the developer). Some drivers will provide this full concurrency. Others may execute one statement and wait until it completes before sending the next.
One specific use of multi-threading is to cancel a long running statement. This is done by using one thread to execute the statement and another to cancel it with its Statement.cancel() method.
Restated again for Oracle; Will threads run concurrently when using the same connection and statements, or will the calls be serialized?

In the connection pool, I specified:
user
password
url
In the deployment tool (Sun Java Appl. Server 8 BE Update 1), I specified the "Resource Reference" for the EJB. This leads to the following entries in sun-ejb-jar.xml:
<res-ref-name>jdbc/pdisasdb</res-ref-name>
   <jndi-name>jdbc/pdisasdb</jndi-name>
      <default-resource-principal>
         <name>myname</name>
         <password>geheim</password>
      </default-resource-principal>
</resource-ref> The strange thing is, that now it works without this entry - but I am not gaga, yesterday it doesnt...

Does wls8.1 install with oracle jdbc drivers in the classpath by default?

I just went through the 8.1 install tonight and it looks to me like the
oracle jars are in the default weblogic classpath.
set
WEBLOGIC_CLASSPATH=%JAVA_HOME%\lib\tools.jar;%WL_HOME%\server\lib\weblogic_s
p.jar;%WL_HOME%\server\lib\weblogic.jar;%WL_HOME%\server\lib\ojdbc14.jar
Why is that? I don't have oracle, and with just learning how to use wls, it
took me a bit of time to finally figure this piece out (trying to get MySQL
drivers loaded). Not everyone has Oracle installed, so why put it on the
classpath for all servers/domains when they startup?
Thanks.

I'm not sure what the best practice is.
The Oracle driver is set in
bea/weblogic81/common/commEnv.cmd or commEnv.sh.
There is a WEBLOGIC_CLASSPATH that has the jars in it and I always
put my stuff at the beginning.
I suspect that the preferred way of doing this is to update
/bea/weblogic81/samples/domains/examples/startExamplesServer.cmd
or whatever script is used to start the server.

Hey Stephen, thanks for the reply.
You got it to work without probs? COOL! :> Where did you stick the driver
and where did you put the jar reference (in which cmd/sh file and where
abouts in the file)? Inquiring minds want to know! :>>>> I tried looking
on the web, but I was referenced to some PRE_CLASSPATH params, as well, as
putting it into my own directories... I'm just looking to find out what dir
is the best practise to dump the jar file into and where to put the

One small note, I do dev in WIN and run production on linux (that might

The Oracle driver (client jar) is shipped in the box. Having it in theCLASSPATH makes it easier
for customers that use it.
If you don't use it and you want to use another driver, it won't get inthe way
since your alternate driver will have a different classname.
I installed and ran MySQL with no problems.

How to update oracle jdbc driver to 11.1.0.7.0 JDBC Drivers

HI,
I got a jdbc exception *" java.lang.ArrayIndexOutOfBoundsException "*.
I have known that it is a Oracle JDBC bug and Oracle BUG number is BUG-6396242.
The problem is too many rows per database transaction and it is fixed at version 11.1.0.7 Oracle JDBC Drivers.
Here is the 11.1.0.7 Oracle JDBC Driver Readme.
http://www.oracle.com/technetwork/database/enterprise-edition/111070-readme-083278.html
and the download
http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-111060-084321.html
My question is :
*1.How to update oracle jdbc drivers with those downloads ?*
(ps. I have replaced ojdbc5_g.jar, ojdbc5.jar, ojdbc6_g.jar, ojdbc6_g.jar in $ORACLE/jdbc, but it did'nt work. )
*2.My Oracle version is 11.1.0.6.0, will it be OK if only update the JDBC driver?*
*3.Do I need to update the jdbc driver where my program runs on the client side ?*
Thanks for answers~ :)

Upgrade your database version to 11.1.0.7.
Installation docs are included with all patches and upgrades.

Bug in Oracle JDBC thin driver (parameter order)

[ I'd preferably send this to some Oracle support email but I
can't find any on both www.oracle.com and www.technet.com. ]
The following program illustrates bug I found in JDBC Oracle thin
driver.
* Synopsis:
The parameters of prepared statement (I tested SELECT's and
UPDATE's) are bound in the reverse order.
If one do:
PreparedStatement p = connection.prepareStatement(
"SELECT field FROM table WHERE first = ? and second = ?");
and then bind parameter 1 to "a" and parameter to "b":
p.setString(1, "a");
p.setString(2, "b");
then executing p yields the same results as executing
SELECT field FROM table WHERE first = "b" and second = "a"
although it should be equivalent to
SELECT field FROM table WHERE first = "a" and second = "b"
The bug is present only in "thin" Oracle JDBC driver. Changing
driver to "oci8" solves the problem.
* Version and platform info:
I detected the bug using Oracle 8.0.5 server for Linux.
According to $ORACLE_HOME/jdbc/README.doc that is
Oracle JDBC Drivers release 8.0.5.0.0 (Production Release)
* The program below:
The program below illustrates the bug by creating dummy two
column table, inserting the row into it and then selecting
the contents using prepared statement. Those operations
are performed on both good (oci8) and bad (thin) connections,
the results can be compared.
You may need to change SID, listener port and account data
in getConnecton calls.
Sample program output:
$ javac ShowBug.java; java ShowBug
Output for both connections should be the same
--------------- thin Driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
[ The same - with buggy reversed order (should give no answers):
aaa
--------------- oci8 driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
aaa
[ The same - with buggy reversed order (should give no answers):
--------------- The end ---------------

Use of oracle.jdbc.driver now deprecated.

Hi all,
Just thought of sharing this note with us.,(if its new ..)
http://otn.oracle.com/docs/products/oracle9i/doc_library/901_doc/java.901/a90211/overvw.htm#1008871
Extract ...,
Beginning in Oracle9i, the Oracle extensions to JDBC are captured in the package oracle.jdbc. This package contains classes and interfaces that specify the
Oracle extensions in a manner similar to the way the classes and interfaces in java.sql specify the public JDBC API.
Your code should use the package oracle.jdbc instead of the package oracle.jdbc.driver used in earlier versions of Oracle. Use of the package
oracle.jdbc.driver is now deprecated, but will continue to be supported for backwards compatibility.
All that is required to covert your code is to replace "oracle.jdbc.driver" with "oracle.jdbc" in the source and recompile. This cannot be done piece-wise.
You must convert all classes and interfaces that are referenced by an application. Conversion is not required, but is highly recommended. Future releases of Oracle
may have features that are incompatible with use of the package oracle.jdbc.driver.
The purpose of this change is to enable the Oracle JDBC drivers to have multiple implementations. In all releases up to and including Oracle9i, all of the Oracle
JDBC drivers have used the same top level implementation classes, the classes in the package oracle.jdbc.driver. By converting your code to use
oracle.jdbc, you will be able to take advantage of future enhancements that use different implementation classes. There are no such enhancements in Oracle9i, but
there are plans for such enhancements in the future.
Regards
Elango.

The two main things that would have to change
- driver : com.microsoft.sqlserver.jdbc.SQLServerDriver
- url: jdbc:microsoft:sqlserver://localhost:1433
It may be that this page will help you
http://msdn.microsoft.com/data/learning/jdbc/
You also need to make sure that the files Msbase.jar , Msutil.jar and Mssqlserver.jar are all available in the "classpath"
For a web app, that means these files should be in the WEB-INF/lib directory.
Good luck,

JAR files for SQLJ and JDBC drivers: what is the best practice?

starting a migration from IAS 10 to WebLogic 11g.
Apparently the jar files for SQLJ are not on the classpath by default.
java.lang.NoClassDefFoundError: sqlj/runtime/ref/DefaultContextwhich is the better practice: putting the SQLJ runtime jar into the lib subdirectory of the domain directory, or using a shared library reference? (usage of SQLJ is pretty prevalent in our apps, though we may be getting away from it)
are the Oracle JDBC drivers on the classpath by default?
if not, then the same question: put them into the lib subdirectory of the domain directory, or use a shared library reference?

I'm looking at the setDomainEnv, especially the big note at the top:
>
# WARNING: This file is created by the Configuration Wizard.
# Any changes to this script may be lost when adding extensions to this configuration.
>
and am getting squeamish about editing it...
http://www.bea-weblogic.com/how-do-i-disable-wls-automatically-adding-to-classpath.html looks like the default behaviour is for WebLogic to put $DOMAIN/lib;$WL_HOME/common/lib/ext;$WL_HOME/server/lib/ext on the classpath; there is also a reference to setting weblogic.ext.dirs= when starting weblogic (which means I set the WEBLOGIC_EXTENSION_DIRS environment variable).
http://download.oracle.com/docs/cd/E12840_01/wls/docs103/programming/libraries.html#wp1067450 also refers at the bottom to using the domain /lib subdirectory.
so am I correct that a good practice is to just put the jars I think I will globally need into $DOMAIN/lib, rather than putting them in $WL_HOME/common/lib/ext, $WL_HOME/server/lib/ext, or fiddling with the WEBLOGIC_EXTENSION_DIRS environment variable?

Oracle10g Jdbc Drivers issue with EJB on Weblogic 7

Hi there,
We are facing a critical issue on production environment related to Oracle jdbc drivers.
We have a J2EE application with swing client. We are using MVC framework where client calls go to stateless session bean which redirect it to specific POJO which then uses Entity Beans for persistence.
We have following environment.
JDK1.4.2, Weblogic 7 with SP5, Oracle10g on AIX 5.2
Now the problem is that we were using Oracle 8 jdbc driver classes12.zip for our application. Everything was working smoothly. Recently we moved our weblogic and oracle Servers machines locations, after that movement we started to get an exception when weblogic initializing connection pool that makes connection to a different oracle10g database. Oracle supports ask us to upgrade the jdbc driver. So we moved to 10g driver ojdbc14.jar but during testing one functionality is failing with a exception where rest of application seems to be working fine. The exception occurs when we try to post a record and during the creation of a child entity bean the transactions rollback for some unknown reasons. Using the old oracle8 classes12.zip driver the same code working fine again. We have also tried the classes12.zip driver of Oracle10g but error persist. I have checked the code and deployment descriptors but they seems fine. If i comment the creation of that particular entity bean the parent bean get created successfully and transaction commit successfully. Please also note that we have not created any relation b/w both entity beans not even in the database. They both are sort of independent.
Can any one having any idea why Oracle10g driver not working or what might be the problem with our configuration. Any help will be highly appreciated. Please see the Exception below.

Oracle/JDBC Memory Leak

I am using the Oracle 7 client with the JDBC driver for Java 2. I am also using the Sun jdk 1.3 SE. Every time I establish a connection to any Oracle database, there is a bit of memory that is lost and can not be reclaimed. A simple program that connects to the database via DriverManager.getConnection(), followed by Connection.close() inside a loop shows the memory gradually increasing. Is this a bug? If so, where is the patch?

the first jdbc drivers certified to work with java 2 (aka jdk 1.2) were called
"jdbc 8.1.6sdk". They have been replaced by jdbc816 and jdbc 817 plus their related patchsets.
the version 7 jdbc drivers went out of support on dec 31, 2000 along with the rdbms 7.3.x product suite.
patches are not generated for "out of support" products.
jdk 1.3 is not certified with any oracle jdbc drivers yet, however, some people have been able to use it with the 816 or 817 jdbc drivers with minimal problems.
be advised...
any problems you run into with oracle jdbc drivers while using jdk 1.3 must be reproduced with jdk 1.2.x in order for a bug to be filed.

Oracle JDBC Thin Driver for oracle 9.2.0.4

Hi,
It would be nice if someone please guide me to the download of Oracle JDBC Thin Driver for oracle 9.2.0.4.
Thanks in anticipation

user566773,
As far as I know, all Oracle JDBC drivers are meant to be backward compatible.
According to the table on the following Web page, the latest Oracle JDBC driver can be used with Oracle 9.2.0.x DBMS.

Good Luck,
