JDBC 2.0 compliance of Thin driver

Does the Oracle 8.1.5 version of the JDBC this driver support updatable results sets?

Hi Mike!
You are on right track Mike. You can create new Domain, deploy application there and use the required classes12.zip file by pointing to it first in the weblogic classpath. It has to be in seperate JVM though(different console) to take effect of another classes12.zip.
Thanks,
Mitesh

We are about to deploy our app that is using CMP 2.0 entity beans on WLS 7.0 and it requires an older version of the oracle thin driver because of known bugs in the driver. The problem is there are multiple applications on our staging server and we don't want to effect them by changing the version of classes.zip in WL_HOME\server\lib\classes12.zip. Any thoughts? Could we just create a new domain for the new application and alter the classpath in the start script to find a local copy of classes.zip?

JDBC logging disabled with Oracle thin driver

Hi,
I am trying to turn on JDBC logging through the weblogic console application (WL
6.1 with CMP). In the jdbc log file I do not see the SQL statments.
It looks like logging is somehow disabled (check one of the logs statements below)
by some means. Any ideas, I am making use of oracle thin driver.
Thanks

Mohit,
Remove oracle/jdbc/driver/OracleLog from classes12.zip, and it should
work (it needs to pick up only this class from weblogic.jar).

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.

Memory Leak when TOMCAT connects to Oracle 10g RAC using JDBC Thin driver.

We had experienced Memory leak when a Oracle 10g (10.2.0.3) RAC node was evicted. TOMCAT app server is connecting to the Oracle 10g RAC database instances using JDBC 10.2.0.3 thin driver.
Anyone had similar experience?
Any ideas? Any bugs reported/fixed?
Thanks,
Raj

If you're doing XA, we absolutely do not support
driver-level load-balancing OR failover. Use neither.
For non-XA, you can use driver-level failover. For
non-XA, you could set load-balancing, but it won't
help because we get connections from the driver,
and keep them indefinitely, so the driver never gets
the chance to affect which connections the pool
uses after that.

Does oracle 8.1.6.0 jdbc thin driver support jdk1.3 and oracle 8.0.5 database ?

I have downloaded oracle 8.1.6.0 jdbc thin driver(named classes12.zip) to run with jdk1.3 to access oracle 8.0.5, but when I compile and run the jdbccheckup.java downloaded from oracle website like this:
javac -classpath d:\jdbc\classes12.zip jdbccheckup.java
(compile succeed)
java -classpath d:\jdbc\classes12.zip jdbccheckup
an error occured:
Exception in thread "main" java.lang.NoClassDefFoundError:jdbccheckup
Why??????

Try this isntead.
java -classpath d:\jdbc\classes12.zip;. jdbccheckup
an error occured:

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 ---------------

[ The same - parametrized (should give one row): ]

Error Code Definition for JDBC Thin driver

Would like to know where I can find the definition of error codes
for JDBC thin driver to Oracle 7 database. Right now, when I have
database errors, I get SQL execption with CODE=XXXXXX. Need to
know the definition of the error codes in order to decide whether
the application shall retry or quit or do something else. Thank
you in advance.

Hi,
thin client session Language is controlled by java Locale.
Based on testing code, ORA- messages are localized after the connection is successfully established. ORA- messages returned in the middle of connecting are in instance language.
So, as far as I can say, you need to catch exceptions from DriverManager.getConnection(url, info); and translate them on your own.
Once the connection is successfully returned, ORA- message language is defined by java Locale.
Tests were performed on Oracle 10gR2 (both thin driver and DB).

Jdbc oracle jdbc-thin driver subname

I am working on Windows 2000 environment, using oracle8i 8.1.7 JDBC-Thin driver for use with JDK 1.2.x. The oralce8i 8.1.7 database is on another linux box. I can access the linux box through its ip address, but not by its hostname since it's not accessiable by the dns server. In my code, in the JDBCUrl, I used ip address instead of the hostname, e.g. "jdbc:oracle:thin:@10.0.113.108:1521:ora1". But I got the error like: "java.sql.SQLException: Io exception: The Network Adapter could not establish the connection". If I add a entry in my working machine's hosts file to map the hostname, I can fix the problem. But I don't know if this is the solution, or there is other better solutions.
Thanks

Using a hosts file entry is a common solution for problem where the dns lookup does not contain an entry for a RDBMS server platform.
The real solution is to resolve this issue :
"where the dns lookup does not contain an entry for a RDBMS server platform."

Oracle JDBC Thin Driver

I am using CLOBS with the Oracle thin driver and am experiencing horrible performance. We need datavalues more than a VARCHAR2 and have used CLOB but the method Oracle uses to get the data in and out is super slow.
MS SQL Server JDBC with text is awesome and fast. But Oracle is slow and very cumbersome.
Help

We are using 9.0.2.
So what you are saying is although the column is CLOB
in Oracle 10 g we can use a normal result set
rset.getString( 1 ) no special oracle stuff just the
e Oracle thin driver for 10g?
Also this will retrieve a String greater than 4000
bytes?Exactly. Not only you can retieve a clob as string, you can also insert clob
as a string too. Here is the code I referred in last post in case you do not

Oracle JDBC thin driver on NT vs IBM mainframe Linux

We are develping an Java 3-tier web application on NT platform. The database is Oracle 9i. The JDBC Driver is Oracle thin driver (oracle.jdbc.driver in classes12.jar). Java is JDK1.3. We are told recently that we may need to deploy this application on IBM mainframe Linux systems when we go production. pplication server will be running on IBM mainframe Linux, and assume Oracle will be the same.)
My question is if you know that we will be able to use the same Oracle thin driver that we use on NT platform when we deploy our application to IBM mainframe Linux system. Is there a specific JDBC driver that we must use when running application server and Oracle on IBM mainframe Linux
Thanks for your help in advance.

Hello,
No, thin driver is same for all platforms (binary) - You must set SQL*Net on Linux only

Oracle JDBC thin driver question

Does anyone know if there is a JDBC thin driver available for Oracle that supports "HTTP tunneling" of the SQLNET wire protocol?
Such a driver would package the SQL*NET data stream into HTTP or HTTPS packets and connects to a Servlet proxy on the Web host that unpacks the data and forwards the SQL*NET stream to the Oracle RDBMS and returns the response the same way.
This would help me overcome some firewall issues I'm seeing since HTTP/HTTPS ports are usually opened through a firewall. I know Sybase has a JDBC dirver that does this for their TNS protocol and was hoping some company has developed this for Oracle.
Thanks in advance...

The easiest thing to do is download it as an archive with your applet.
Otherwise, you have to have the files on every client machine.
For netscape, put the classes111.jar in the java classes folder typically:
c:\ProgramFiles\Netscape\Communicator\Program\java\classes.
I'd expect that IE would be setup in a similar way.

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,

JDBC Thin Driver 8.17 Release 2

Is the Oracle Direct Driver (JDBC Thin Driver 8.17 Release 2) compatible with other oracle versions like 8.15 and 8.16? Is it backward compatible to older releases. I have tried it and it does work, but I want to make sure there are no known problems going backwards because we have several versions in our shop.
Thanks
Brian
